INTRODUCTION The problem of creation and use of sorption materials are current interest for the practice of the modern medicine and agriculture. The knowledge of physical and chemical rules of carbonization, activation as well as sorption and desorption processes is of particular importance in the case of application of the nanostructured carbon sorbent agent for high purification of water contaminated with pesticides, as well as for reducing the concentration of cytokines in the blood of sepsis patients. Practical importance is production of a biostimulant using a carbon sorbent for a significant increase in productivity, which is very relevant for the regions of Kazakhstan. As a result of the comprehensive analysis carried out in the work the biostimulant obtained by means of highly-porous carbon sorbent was used in field experiments to stimulate vegetative growth of plants and to form reproductive organs, to increase grain crops yield and their resistance to biotic and abiotic stresses. In addition, biological and cytotoxic activities of obtained fusicoccin open possibilities for their use as anti-cancer drugs. The practical relevance of the work was confirmed by the receipt of the passport safety of chemical production for “PMF” (phyto micro-fertilizer), approved by the Committee of Industry of the Ministry of Industry and New Technologies of the Republic of Kazakhstan from June 16, 2014 (RK-Chemical Production №0000288). The achieved results are aimed at the development of nanotechnology scientific bases in the field of biostimulators produced to improve food crops yield and to determine their biological and cytotoxic activities.
FUSICOCCIN, PROPERTIES AND APPLICATION
1.1 The properties of fusicoccin and its application as an anticancer preparation Fusicoccin was discovered in 1964 by the Italian scientist Alessandro Ballio as the phytotoxin of the phytopathogenic fungus “Fusicoccum amygdali Del”. This phytotoxin was able to kill young almond trees as follows: this toxin opened stomata of leaves which did not close after. In consequence of the excessive transpiration and because of the weakness of the root system young trees were dying rapidly from drought, i.e. fusicoccin is a natural desiccant. In the laboratory of Professor A. Ballio the structure of this phytotoxin was determined as is shown in Figure1. Considering the fact that fusicoccin refers to natural terpenoids as well as the gibberellin Gronevald et.al. developed a hypothesis about the kinship of gibberellin and fusicoccin. Indeed, they both are diterpenoids, metabolites of phytopathogenic fungi. Over time, the number of known gibberellins increased rapidly from few in 1960 to more than eighty by the end of the 80s. The same for fusicoccins: now more than 15 related compounds of this group are known (denoted by literal characters – A, B, C, etc.) . Preliminary data on the presence of substances of the fusicoccin family in higher plants were published first by Muromtsev and his co-wokers in 1980. Later for the detection of fusicoccin a gas chromatography, mass-spectrometry was used (GC/MS) with a preliminary fractionation of the material by the high performance liquid chromatography (HPLC). Initially, the authors have developed an identification method for fusicoccinal metabolites in the culture fluid of the fungus F. amygdali by the combined method of the gas chromatography and mass spectrometry of trisilil derivatives, when the detection is performed through several chosen characteristic ions. To obtain fusicoccin, the authors used corn cobs and cabbage leaves, 12
which were homogenized in ethanol. The alcohol extracts were concentrated. The concentrate was extracted by chloroform. The chloroform extract was subjected to the liquid chromatography. The obtained peaks were subjected to the gas-liquid chromatography followed by mass spectrometry. The content of the endogenous fusicocin A in plants was 10-11-10-12 M, which is 2-3 orders lower than that of the endogenous gibberellins. Hence it becomes clear that the problem of preparative quantities extraction of natural fusicoccin from higher plants is a very difficult experimental problem.

Then, the same authors tried another shot to extract natural fusicoccin from higher plants. At this time, as the object for the fusicoccin extraction the authors used a sterile culture of transformed horseradish roots distinguished by the intensive growth. This objet was chosen for the following reasons. Firstly, it eliminates the possibility of contamination by microorganisms and fungi that may be sources of fusicoccin. Second, the culture of roots cells can be obtained in very large quantities due to their intensive growth. From cultures of roots cells the authors obtained alcohol extracts. The extracts were evaporated in vacuo, the aqueous residues were extracted by chloroform, followed by determination of the presence 13
of fusicoccin in aqueous and chloroform phases by immune methods. Fusicoccin was in chloroform, whereas in the aqueous phase there were found only trace amounts, that eliminates the possibility of effective interaction of such compounds as proteins and sugars with receptors and antibodies. Substances similar to fusicoccin were discovered at all stages of roots cultivation (since 14 days). It was found that the maximum content of fusicoccin in grown sterile roots is up to 150 nM per kilogram of roots. Mass-spectrometric analysis of the obtained fractions showed mainly the presence of fusicoccin type A, also these analyses indicated the possible presence of another unidentified fusicoccin. As a result of undertaken studies Muromtsev and his co-wokers made a conclusion that identification of endogenous fusicoccin is a very difficult task . The first and main of the identified fusicoccins, fusicoccin A, is a glycoside of the carbotricyclic diterpene with a molecular weight of 680 Da gross and the formula С36Н56О12 (Figure 1). The aglycon part of fusicoccin molecules is represented by the tricyclic system including one eight-membered and two five-membered rings. Besides the basic compound (fusicoccin A) the fungus produces some similar compounds (more than 15), which differ in the degree of acetylation, positions of acetyl groups, the degree of oxidation of the aglycone part of the molecule. Thus, ten fusicoccins represent monoacetates, diacetates and triacetates. Another series of fusicoccins has a more simple structure: their C20-atom is not oxidized. The analysis of literature data shows that the fusicoccin molecule is not a unique structure and connections with the similar “skeleton” which are derivatives of the dicyclopentane and cyclooctane (the ring system 5-8-5), are widely distributed in the nature. They were found in fungi and algae, higher plants – liverworts, flowering plants, and even among animals (insects). If and when discovered and identified various representatives of this class of terpenoids the trivial names of organisms-producers are assigned to them. Thus, for example, the fusicoccin extracted from the liverwort Plagiochila acanthophylla is called fusicoplagin C, the fusicoccin extracted from the liverwort Anastrepta orcadensin is anadensin, the fusicoccin extracted from the giant kelp Dictyota dichtoma is epoxydictimen. It was proposed to combine compounds 14
having dicyclopentane and cyclooctane “skeleton” into groups of terpenoids of the fusicoccane range. The basis of the range of such compounds was formed by the hypothetical trans-sin-trans C20 hydrocarbon that was named fusicoccine. 1. The further study of fusicoccin showed that they demonstrate various physiological and biochemical properties. This made it possible to class it among natural regulators of the plant growth. 2. The cells of many organs and tissues of higher plants respond to the treatment by fusicoccin with the increase of the volume, with which such effects can be associated as the opening of the stomata, cells growth and elongation. There are data on the possible role of fusicoccin as an endogenous regulator of seed germination and root formation. 3. Fusicoccin effectively removes seeds from the deep rest. The laboratory of Muromtsev first discovered that fusicoccin actively stimulates the rhizogenesis for number of cultures. Fusicoccin had a very interesting effect on germination of pea seeds. So it stimulated the growth of cotyledon cells and at the same time inhibited the growth of the embryonic axis, which indicates the polarity of the fusicoccin action. It was found that fusicoccin plays an important activating role at early stages of legumes contamination with microorganisms of the genus Rhizobium spp, i.e. fusicoccin activates the nodulation in legumes. 4. Fusicoccin activates absorption of carbon dioxide by columnar cells of the leaf. Also fusicoccin regulates the concentration of ascorbate in the apoplast of coleoptile cells Vigna angularis. 5. One of the most striking hormonal properties of fusicoccin is its anti-stress activity. Muromtsev and his co-wokers showed that fusicoccin can increase the seed germination in conditions unfavorable for germination, for example: at elevated and low temperatures, excessive moisture, salination. The co-wokers of the Institute of Plant Physiology showed that the seeds soaking (0.68 mg/l of fusicoccin) and also spraying of plants of winter wheat, rye, barley (0.34 mg/l of fusicoccin) leads to the increase of the frost hardiness of plants at booting and tillering phases. Moreover, the increase of the frost hardiness correlated well with the degree of development of the photosynthetic apparatus and sugar accumulation, as well as with the development strengthening of the 15
endoplasmic reticulum in cells. It is shown that fusicoccin protects rice plants under salinity, increases the resistance of potato tubers to some diseases. Fusicoccin is undoubtedly one of the most powerful anti-stress compounds for plants. The positive role of fusicoccin in adaptation to osmotic stress is shown in the work . 6. The available data on the study of the biochemical activity of fusicoccin are of particular interest for us. For the first time  Ballio and his co-wokers discovered fusicoccinal receptors on the plasma membrane isolated from the roots of maize seedlings. They also created proteoliposomes with the inclusion of isolated fusicoccinal receptors and studied properties of this artificial system. De Boer and his co-wokers developed a method for purification of FC-binding proteins on a special affine sorbent to which the biotinylated fusicoccin is ligated as the active group. A number of authors have also performed some studies on the extraction of fusicoccin-binding proteins . For fusicoccin the alleged receptors are described – fusicoccinbinding proteins (FCBP) of two types. The first type has a high affinity for fusicoccin with a dissociation constant (Kd) about 10-10 М (high-affinity HA), and the second receptors type with a lower affinity, Kd about 10-7 М (low-affinity LA). They were first detected in the fraction containing plasma membranes of maize coleoptiles. It was shown in the publication that the ratio of the quantity of highaffinity receptors sites to low-affinity receptor sites on isolated membranes [HA]/[LA] is approximately one to two. The authors made a conclusion that only the high-affinity binding site is involved in action of fusicoccin. This point of view in the following years became dominant. Thus, the authors suggested that participation of the high-affinity site as a fusicoccin receptor is according to the reconstruction of the system in vitro consisting of fusicoccin-binding protein and Н+-ATPase [А][6-8]. A small quantity or absence of low-affinity sites on most isolated membranes may be due to their inactivation during the isolation process. It is explained by a much greater lability of low-affinity binding sites in comparison with high-affinity ones. Currently, the issue of the functional role of the high- and low-affinity sites is the subject of research.
Membrane effects of fusicoccin belong to rapid answers: usually stimulation of protons emission begins immediately after adding fusicoccin and has no lag phase. In addition to the rapid membrane effects FC may have a prolonged, generalized action on plants that speaks in favor of its hormonal properties. Conspicuous is the fact that the current fusicoccin doses (10-20 mg / ha) are by two-three orders lower than that of other plant phytohormones and growth regulators (including those for gibberellin). In the publication of Babakov  the role of FC in the activation of protein kinase is discussed. Claudio Olivari and his co-wokers  first stated that the activation process of Н+-ATPase by fusicoccin requires the presence of another protein. In his work Claudio Olivari found that the phenylarsine oxide was a specific inhibitor of activation process of Н+-ATPase by fusicoccin. Very interesting is the action of fusicoccin on cells. First of all it concerns the acidification of the content of the cell under the influence of fusicoccin. The data that fusicoccin stimulates the protons emission in oat coleoptile cells were first specified in the work. The listed processes can be activated upon condition of the work stimulation of Н+-ATPase or reduction of the ions leakage through ion channels of a plasmalemma. Actually, according to the latest data, fusicoccin affects both the activity of H+-ATPase, and the conductivity of plasmalemma potassium channels .
1.2 Plants growth stimulators. Physiological activity and mechanism of action As of today growth regulators include “natural and synthetic chemical substances, applied for plants treatment for the sake of improvement of their quality, changing processes of their vital activity or structure, to increase yields or to simplify winning”. As V.S. Shevelukha points out, this definition is to be supplemented with the most important property of growth regulators – causing respective effects in exceptionally small doses, what is of a great ecological meaning, as well as ability of some of them to protect plants and crops from stress impacts of the environment and pathogens . 17
M. Derfling in his work  “Plants Hormones. Systemic Approach” points out main principles of growth regulators action: 1. Regulator imitates endogenous hormone. Thus hormone action increases. In this case growth regulator is identical to the hormone or has similar physiological activity. 2. Regulator disturbs the process of hormone biosynthesis. 3. Physiological activity is inherent not into the introduced regulator itself, but to the product of its decomposition. 4. Regulator has a toxic action. In the first three cases growth regulators change natural hormonal balance in plants, treated therewith. About five thousand of compounds, having regulatory effect, have been found or studied in a varying degree over last decades. About 50 preparations of them have found their practical application. Te overwhelming majority of such physiologically active compounds can be rated among one of the three following categories: 1. Compounds, produced by inferior plants (fungi, mosses) and regulating their development. 2. Compounds, synthesized by microorganisms, which have the ability to influence growth of higher plants. 3. Compounds, formed by higher plants and influencing their growth, but in case of their introducing in intact plants or in tissues segments exogenously. Representatives of two last groups are mainly represented by phytohormones and their synthetic analogs. V.V. Polevoy  gives the following definition “phytohormones are signal substances, without which plants organism cannot exist as a comprehensive whole”. Phytohormones cause relatively quick physiological reactions, connected, obviously, with membranes, and more slow changes, depending on synthesis of proteins and nucleic acids, in competent cells. As of today five main groups of phytohormones are known: auxins, gibberellins, cytokinins, abscisins and ethylene. Few more endogenic regulatory substances have been detected lately, they are brassinosteroids, jasmine and cetonitr acids. The question, whether such a compound as fusicoccin can be allocated to phytohormones, is disputable . 18
Auxins. The most important representative is indolil-3-acetic acid (IAA). IAA and its synthetic analogs in essence involve all aspects of vital activity of a plant organism. They affect division, elongation and differentiation of cells, induce root xylem formation. Auxin is necessary for DNA replication initiation; it is capable of maintaining cells trophism and hamper ageing processes . Gibberellins are a large group of compounds of tetracyclic diterpenoids class. Their characteristic effect is acceleration of division of cells of sprouts apical meristems, as well as of cambium. Gibberelins activate seeds germination of many species; they play a significant part in plants transfer to flowering. Principle of action of such wide spread retardants as chlorcholinchloride etc. is based upon ability of these substances to inhibit gibberellins synthesis . Cytokinins. By their chemical nature they are mainly substitutes N-aminopurines. The most important representatives: zeatin, natural cytokinin, as well as kinetin and 6-BAP, are widely used in laboratory studies. Cytokinin activity is also inherent in urea derivatives. Cytokinins stimulate cells division, activate seeds germination, play an important role in the process of cell differentiation and organogenesis of a plant, as well as promote ending dormate state of tubers and buds of woody plants irrespective of a season, are able to delay ageing process . Natural cytokinin was first isolated in 1964 by Letham, who used multistage treatment of corn seed alcohol extract on the stage of milky ripeness for that purpose. As this cytokinin was isolated from maize, it was called zeatin. Natural cytokinin formula is presented in Figure 2. Zeatin was also found in ripening fruits of plump, growing fruit of apple tree, as well as in culture liquid of mycorrhizal fungi. Dihydrozeatin was found in lupine seeds. Cytokinins were also found in ferns, mosses and algae. Another substance, related to zeatin, was isolated from the culture of bacterium, pathogenic for plants, Corynebacterium fascians. Its effect on plants resembles much the effect of cytokinin preparations and is connected with apical dominance disturbance. Thus, zeatin and compounds with cytokinin activity, related to it, are widely spread among the representatives of the plant kingdom.

Of the brightest physiological manifestation of cytokinin action is its ability to delay aging of leaves, that was first demonstrated in the work by Richmond and Lang, in which they succeeded to retain yellowing and protein disintegration in cut off burdock leaves with the help of phytohormone (Xanthium pensylvanicum Wallr.). In these experiments, the cut off burdock leaves, which ended growing, were put into cytokinin solution. Intensive decrease of chlorophyll and protein was in progress in control leaves, so that on the 12th day of testing its loss was 60% of the initial content. Leaves on phytohormone solution remained green and have lost only 15% of protein, that corresponded to its loss for the same period in analogous leaves on a plant. Thus an effective mean for delay of yellowing was found and it seemed rather likely that cytokinins are the product of root metabolism, which are necessary for normal life support of leaves. A more substantial study of the effect of cytokinin on cut off leaves was conducted in works [20-23] by Mothes et al. They showed that biostimulant action in case of its applying to the leaf surface remains strictly localized in the place of its application. That is why, if only one part is sprayed with cytokinin, it remains green and viable for a long period of time, while the other part turns yellow and dies. Such application of phytohormone on one part of a leave was used in studies on cut tobacco leaves, which ended their growth. These leaves were compared to the leaves sprayed with water or cytokinin water solution in whole (10-20 mg/l). For the period of study all the leaves were placed in wet camera under sparse light. In control leaves, which received only water, within 10 days of the test a sharp decrease of protein and chlorophyll content, which was accompanied by outflow of nitrogenous compounds to the footstalk, was registered. Spraying the whole leaf with biostimulator prevented protein content decrease in lamina and outflow of nitrogenous 20
compounds to the footstalk. These results corroborated the data provided by Richmond and Lang . As was mentioned earlier, cut off leaves lose their ability to move metabolites from one part of a leave to another and acquire it only on acceleration. Under the influence of cytokinin moving of metabolites from one part of a leave to another was sped up in cut leaves, and thus, hormone in this respect is a kind of substituted roots action. All this made assumption of the fact, that cytokinins are the factor of root metabolism, with the help of which roots regulate metabolism in leaves, rather probable. This assumption was even more corroborated by stimulating the effect of cytokinin on the growth of young leaves, which didn’t finish growing. Stimulation with cytokinins was expressed both in etiolated leaves in dark, and in green leaves in light. Whereas in certain cases, it was shown that cytokinins can cause secondary growth of leaves, which have already finished their growth. In order to check, how widespread the ability of leaves to react to cytokinin in plant kingdom is, Kulayeva et. al.  studied cytokinin effect on cut off leaves of the plants, belonging to various systematic groups, picked up from the point of view of phylogenetic aspect. For that purpose cut off leaves were placed in wet camera under sparse light at room temperature and one half of each leaf was sprayed with water, and the second one – with kinetinin water solution (20 mg/l). The study performed showed that kinetinin slowed down yellowing of the half of a leaf, treated therewith, in representatives of various families of plants from phylogenetic point of view, including the oldest ones (Ranales) and the most advanced (Glumiflorae и Campanulatae) families. Cytokinin affected leaves of both monocotyledonous and dicotyledonous plants. It provided effect on the leaves of plants, belonging to various ecological groups, e.g. on steppe plants – feather grass, and on the representative of the flora of moist places – calla. Archeogoniates proved to be also kinetininsensitive. In particular, leaves of a gymnosperm, Ginkgo bilobа, and a spore-bearing plant, a fern Osmunda claytoniana, reacted to kinetinin. Thus, universal character of cytokinin action on all the types of plants was corroborated. Interesting results were obtained in work [26-29]. The possibility of secondary virescence of cut off 21
leaves under the influence of cytokinin was shown. Already yellowed tobacco leaves were taken for that testing. The leaves were cut from the plants and were placed into moist conditions. One half of each test leave was sprayed with highly active cytokinin – 6benzylaminopurine (BAP) – solution (20 mg/l), and the other one – with water. Probes for biochemical analysis and cytological studies were taken from each half. BAP caused secondary virescence of halves of cut off yellow leaves, treated there with. Halves of all the leaves, which weren’t treated with BAP, continued yellowing until the end of the test (10-11 day) most of them died off. Virescence continued during the whole period of study. It occurred due to both chlorophyll а, and chlorophyll b. The increase in chlorophyll content in initially yellow leaves lasted longer and its content practically reached the content of old, but still yellow leaves on the same plants, from which test leaves were cut. Thus, reversibility of old leaves yellowing occurred the more brimful, the less was the result of the process of yellowing. In a half of a leave, receiving only water, protein and RNA content continued decreasing. As was pointed out earlier, decomposition products were not accumulated in a yellow half of a leaf, but were moved to the part, resuming its vital activity under the influence of cytokinin. The next task was to determine, whether it is roots, which supply leaves with cytokinin-type substances. It was shown in Mothes laboratory that tobacco cut leaves are highly sensitive to kinetinin, whereas leaves on the plant provide no reaction to kinetinin. In order to find out which organs of a plant prevent demonstrating cytokinin action to plant’s leaves, reactions of plant’s leaves to phytohormone in the following variants were compared: 1 – cut leaf; 2 – leaf on a sprout, cut at root collar; 3 – leaf on a stump with deleted remaining top, but preserved root system; 4 – leaf on an entire plant. Third tier tobacco plants pale green leaves were taken for the study. It was found that phytohormone delays yellowing of that part of a leaf, which it was applied to. Difference in pigmentation of the two halves of a leaf, resulting therefrom, is a rather sensitive test of leaf reaction to cytokinin. It was also found that hormone was effective when affecting leaves on remote sprout; at the same time it wasn’t effective when affecting the leaf, connected with stump root, or the 22
leaf of entire plant. Thus it was proven that it is the root which is the producer of cytokinin for leaves. Analogous data as to the importance of the root as the source of cytokininfor plants were obtained for haricot plants in Mothes lab [30-33]. Cytokinins effect was also evident on various cell structures of a leaf. It was clearly seen, e.g., on internal chloroplasts structure. Internal chloroplasts membrane structures are the place of pigments and enzymatic systems localization, providing for water photolysis and photosynthetic phosphorylation. It was shown that under the influence of cytokinins chloroplast structure is preserved. Thus it was found that cytokinins are one of the factor of hormonal regulation of development and maintenance of chloroplasts internal structure, providing for their photosynthetic activity. According to the data provided, cut off wheat leaves also showed that phytohormone delays chloroplasts decomposition in cells. It delayed grains decomposition and chloroplasts filling with osmiophil globules in disks of Brussels sprout leaves in the same way. This effect of cytokinins on chloroplasts structure is to be reflected at their functional state. Membrane apparatus of chloroplasts is the form of spatial organization of pigment and enzymatic photosynthesis system. That is why development of membranes under the influence of cytokinin causes activation of photosynthesis in leaves. Abscisic acid is growth inhibitor and in many cases acts as auxins, gibberellins and cytokinins antagonists. Abscisins extend dormancy of many plants species, accelerate protein and nucleic acids decomposition and improve plants resistance to unfavorable environment factors, are antitranspirants, without affecting photosynthesis intensity. Ethylene is the only gas phytohormone. Ethylene delays mitotic process in root, sprouts and axillary buds meristems, stops auxin polar transport, that causes such processes, as exfoliation, blossom fading and fruits falling, organs ageing. Ethylene accelerates fruits ripening. On the basis of 2-chlorethylphosphonic acid preparations, producing ethylene, viz. ethrel, capozane and others are created, which are successively applied against grain crops lodging. Brassinosteroids. Phytohormones of steroid nature. They were discovered relatively recently: in 1979 chemical composition of 23
brassinosteroid was determined. Brassinosteroids are contained in various plants organs, whereas the highest content of these phytohormones is characteristic of pollen. One of the most important functions of brassinosteroids is their ability to increase plants resistance to unfavorable environmental conditions . Thus, a significant role in response reaction of a plant to various external influences belongs to phytohormones. Diversity of physiological effects of phytohormones is mainly determined by the fact that they regulate realization of cell genetic program, implementation of which needs coordinated action of a variety of enzymatic, structural and regulatory proteins. The primary role of the majority of phytohormones in a plant cell is in genes expression control. Whereas experimental data point out to several levels of phytohormones effect on genes expression, including formation of an active transcription complex, provision of matrix RNA stability as well as regulation at translation level. To implement this function, a hormone is to bind with receptor protein and to get transported to the nucleus in form of hormonereceptor complex. In the nucleus hormone-receptor complex binds with chromatin that causes its activation and transcription induction forming a respective matrix of RNA. Phytohormones directly influence DNA by means of its enzymatic methylation regulation. Auxins, gibberellines and cytokinins inhibit replicative DNA methylation and thus can cause formation of non-methylated sites in DNA, controlled by them, which are necessary for certain genes expression. It was shown that fusicoccin, a regulator of growth of plants of terpenoid nature, is as well able to control the degree of DNA methylation, extracted from wheat seeds embryos. Apart of direct impact on DNA phytohormones actively influence the molecular and genetic processes at transcription and post-transcription levels. Cytokinins and their synthetic analogs increase activity of polymerases I and II, that causes RNA synthesis enhancement, increase the amount of ribosomes as well as activate polysomes formed from ribosomes and mRNA present in the cell. Auxin and its analogs have the ability to activate enzyme RNA polymerase and to stimulate RNA synthesis.
A more detailed review of phytostimulators action will be given at the example of fusicoccin, a well-known biosynthetic plants growth stimulation of terpenoid nature. Fusicoccin was first discovered in 1964 as product of metabolism of a fungus Fusicoccum amygdali Del., causing cancer in stone and almond trees . According to its chemical nature fusicoccin is a glycoside of carbocyclic diterpenoid with molecular weight 680 and formula C36H56O12. It is stated that fusicoccin shows high and versatile physiological activity in high plants organisms, treated therewith [36-41]. Fusicoccin activates cell growth in various organs of flowering plants: in stems, seed lobes, leaves, coleoptiles and roots, showing greater universality of action than auxin, gibberellin and cytokinin. It is found that fusicoccin induces seeds germination. Seeds treatment with fusicoccin solutions replaces durable cold stratification. Fusicoccin induces root formation in grafts of various plants. Fusicoccin is able to cause leaves stromata opening in darkness and thus to improve transpiration. Fusicoccin increases vital activity of cultivated plants in unfavorable soil and climatic conditions, especially under low temperatures, salinization, overwetting etc. Aggregate of data received as of today: a rather broad spectrum of physiological activity of fusicoccin, its receptors identification in plasmalemma preparations from roots and coleoptiles of cereals and germinated garden radish seeds, as well as from leaves of Vicia Faba mayor L. and, finally, discovery of endogenic fusicoccin in cells of higher plants, belonging to monocotyledons and dicotyledons: maize Zea mays L. Sterling breed and headed cabbage Brassica oleracea L, “Zimovka 1474” breed in amounts of approximately 10-8 and 10-9 g/kg allows making a conclusion that fusicoccin pretends for the role of phytohormone with a highly low content in plant tissues. According to modern views, fusicoccin action shows itself both on membrane level and on the level of protein synthesizing. Fusicoccin specifically activates process of intracellular energy of high-energy phosphate bounds turning into the energy of electrochemical protons gradient on the plasmalemma level. The data, obtained in vivo and in vitro, point to the fact that fusicoccin effect is connected with Mg2+ -dependent, K+ -stimulated ATF-aze, 25
which, in its turn, activates proton pump. Stimulation of H+ ATFazes with fusicoccin is shown on various plant materials [42, 43]. According to the point of view of some researchers, H+ pump activation is not a primary reaction to fusicoccin: fusicoccin is able to acidify cytoplasm in plasmalemma, which leads to ATF-aze activation and protons discharge. Though according to the data of other authors, obtained with application of NMR method, fusicoccin does not cause cytoplasm acidifying in cells of peas internodes. According to numerous data fusicoccin does not provide effect on the synthesis of RNA and protein. An assumption is expressed, according to which fusicoccin effect on functional activity of protein synthesis apparatus occurs through activation of proton pump, as well as by means of influencing proteins, already existing in a cell. Though, fusicoccin prolonged influence on the entire plant, such as protection from stress, root formation stimulation cannot be directly connected to activation of proton pump only or other transport plasmalemma system. It is probable, that various fusicoccin effects are conditioned by participation of various types of receptors, which remain not identified. According to the data of various authors fusicossin influences RNA and protein synthesis in isolated seed lobes of pumpkin and in barley plants. According to the data of D.G. Muromtseva , fusicoccin mechanism of action is based upon the increase thereby of activity of RNA-polymerase, bound with chromatin, whereas this activation is of a short-term, transitory character. Stimulation of RNA synthesis with fusicoccin is the result of a regulator effect directly on the ferment, RNA-polymerase, and does not affect chromatin matrix activity. Thus, action of natural and synthetic growth regulators is directly or indirectly caused by their influence on genetic apparatus of a plant cell [45-49].
1.3. Natural small molecules and their use as an anticancer drug Some small molecules that are used in preclinical as well as clinical studies influence PPIs of the Bcl-2 protein family of antiapoptotic proteins . Several compounds have been identified that target the hydrophobic binding pocket, which forms the BH3 binding site in Bcl-2, and prevent thereby the hetero-dimerization of Bcl-2 with pro-apoptotic members and thereby the induction of apoptosis. Another well known example is the nutlins (cis-imidazoline analogs) that target the p53/MDM2 interaction. These compounds bind selectively to MDM2 and prevent thereby the interaction with p53 and enhance the activity of the p53 pathway. It is interesting, that healthy wild-type p53 cells retained their viability when treated with these nutlins, while wild-type p53 expressing cancer cells are killed. Besides these examples many other small molecules are known that prevent PPIs that are beneficial in the treatment of cancer. However, so far not many small molecules are known that affect cancer cells by stabilizing PPIs. In recent years several reviews have been published about the isolation of (novel) natural compounds and active small molecules with an anticancer activity from various sources. Plants supplied several of these compounds while other anticancer drugs have been isolated from marine organisms and microorganisms, like fungi. Although the working mechanism of many active small molecules is not yet (completely) clarified, most new compounds have been shown to belong to diverse structural classes, including polyketides, terpenoids, terpenes, alkaloids, and steroids and to influence PPIs. Furthermore, many drugs (> 60%) that are currently used in cancer treatment are derived from natural occurring small molecules, either directly or indirectly. Paclitaxel (taxol) is, for instance, isolated from the bark of the Pacific yew tree Taxus brevifolia  and the vinca alkaloids vinblastine and vincristine are isolated from the Madagascar periwinkle Catharanthus roseus.
1.4 Fusicoccanes, an interesting group of active small molecules Fusicoccanes are a large group of active small molecules that refer to the terpenoids. They have a typical dicyclopenta[a,d] cyclooctane skeleton (5-8-5 core ring structure), to which various side chains are linked . They are found throughout nature and are amongst others produced by various fungi, higher plants, liverworts, and even insects. A number of biological effects have been described for fusicoccanes on both plants and other organisms, and several of them are caused by the selective targeting of a particular protein or PPI. Some well-studied fusicoccanes are Fusicoccin-A (FC), Cotylenin-A (Cot-A), and Ophiobolin-A (OPH-A) (Figure 3). Fusicoccin-A was first described in 1964 by Ballio et al., and is produced by the fungus Phomopsis amygdali (formerly known as Fusicoccum amygdali Del.) from which more than 30 fusicoccin derivatives have been isolated, among which at least 16 natural derivatives (Figure 3). The fungus infects peach and almond trees, in which the secreted FC stabilizes the complex formed between the Cterminal tip of the plasma membrane H+-ATPase and a 14-3-3 protein. This stabilization irreversibly activates the H+-ATPase, that drives the opening of stomata resulting in uncontrolled water loss and wilting of the tree. Although the only known FC target in plants is the H+-ATPase, at the cell and organ level FC affects a range of different processes, like opening the stomata, breaking seed dormancy, inducing an apoptotic like cell death in sycamore cells, and reducing hydrogen peroxide and nitric oxide production in guard cells [47-51]. Many of these processes can be (in)directly explained by the activation of the H+-ATPase while others suggest the presence of another FC target. FC is not only active on all higher plants, but on other organisms as well. It randomizes, for instance, the left-right asymmetry early in the Xenopus laevis embryonic development  and induces apoptosis in cancer cells derived from different origins, for which the efficacy of FC can be enhanced by combining it with the cytokine interferon (IFNα). Cotylenin-A was first described by Sassa who discovered it in a fungal culture filtrate of Cladosporium sp. And described its 28
growth enhancing effect on plant cotyledons. The structure of Cot-A is rather similar to that of FC, and comparisons made on their effects in plants show that both molecules have similar physiological effects. In some cases FC is more potent (e.g. induction of seed germination and wilting of tomato cuttings), while Cot-A is more effective in others (e.g. stomatal opening and cotyledon elongation). Besides this, Cot-A has been shown to induce differentiation in human myeloid leukemia cells and inhibits the growth of various tumor types both in vitro and in vivo, when combined with IFNα or rapamycin.
Figure 3 – Chemical structure of Fusicoccin-A, Cotylenin-A and Ophiobolin-A 
Ophiobolins (OPHs) are roduced by plant pathogenic fungi belonging to the Bipolaris species. Currently 23 analogs have been identified, to which various biological activities are ascribed that are all damaging plants either directly or indirectly. Besides being harmful for plants, OPHs also possess anti-microbial activities as well as toxicity towards animals and even cancer cells. The working mechanism of most OPHs is not completely clear and probably differs per analog. OPH-A, however, has been shown to mainly function through the specific inhibition of calmodulin, an important signalling molecule.
Anticancer effects have been described for several fusicoccanes, including FC, Cot-A and OPH-A. All show a clear growth reduction at relatively low concentrations (IC50-value mostly in the μM range, depending on the cell line). Although the tumor selectivity differs per molecule, with some being relatively cancer selective while others are indiscriminate and kill healthy cells as well as cancer cells, fusicoccanes form an interesting group of potentially new anticancer compounds. The working mechanism of most fusicoccanes in inhibiting the cancer cell growth is not clear yet. OPH-A most likely acts through the selective inhibition of calmodulin by binding covalently to calmodulin with its C7-aldehyde group . FC and Cot-A both lack this aldehyde group, suggesting that these compounds function through a different cellular target. When combined with IFN, FC and Cot-A both induce apoptosis by the induction of the TRAIL pathway, however, this is most likely the final effect of the combined treatment and the primary target of both compounds is therefore still unknown. Boear and et.al  studied properties of fusicoccin-A as anticancer. We have developed a highly efficient method of producing fusicoccin extract from germinated wheat seeds. This method is based on the selective sorption fusicoccin by nanostructured carbon sorbent developed by researchers at Institute of Combustion Problems . Thus, it becomes possible to create a high-performance domestic anticancer drug.

CARBON SORPTION MATERIALS
The useful properties of activated carbon have been known since ancient times. This traces back to 1500 BC when Egyptians used charcoal as an adsorbent for medicinal purposes and a purifying agent. Around 420 BC it was observed that Hippocrates dusted wounds with powdered charcoal to remove their odor. Ancient Hindu societies purified their water by filtration through charcoal. In 1773, the Swedish chemist Karl Wilhelm Scheele was the first to observe adsorption of gases on charcoal. A few years later activated carbons began being used in the sugar industry as a decolorizing agent for syrup. In the early 20th century the first plant to produce activated carbon industrially was built for use in sugar refining industry in Germany. Many other plants emerged in the early 1900’s to produce activated carbons primarily for decolorization. During World War I activated carbon was used in gas masks for protection against hazardous gases and vapors. Today, activated carbons are used to remove color from pharmaceutical and food products, as air pollution control devices for industrial and automobile exhaust, for chemical purification, and as electrodes in batteries. 500,000 tons per year of activated carbon are produced globally [1-6]. 80% of this is used for liquid phase applications, and 20% is used for solid phase applications. Activated carbon (AC) is a unique material with its immense capacity for adsorption from gas and liquid phases. It occupies a special place in terms of producing a clean environment involving water purification as well as separations and purification in the chemical and associated industries. In these roles, it exhibits a remarkable efficiency as the international production is a little more than a million tons per year, with perhaps 2 million tones being in continuous use. Broadly AC has been used for three main purposes:
Figure 4 – Application of carbon materials 
1. AC is dominantly used for purposes of adsorption in liquidphase. The wide-ranging scenarios for AC are: ‒ drinking water availability, to improve taste, smell and color including ‒ removal of chlorinated compounds and other volatile organic carbons (VOCs); ‒ purification of ground water purity from contaminants coming from disused sites of heavy industries; ‒ treatment of both industrial and municipal wastewater; ‒ mining operations require feed water treatment, metallic ion adsorption (gold and other metals), adsorption of excess flotation reagents and adsorption of natural organic matter (NOM); ‒ pharmaceutical processes, including purification of process water, use with fermentation broths and purification of many products; ‒ the food, beverage and oil industries for removal of color and unacceptable tastes; ‒ the dry-cleaning industries require purification of solvents; ‒ the electroplating industries require purification of wastewaters containing Pb, Cr, etc; ‒ household water purification, cleaning of aquaria and use in oven-extract hoods;
‒ the sugar and sweetener industries need decolorization agents for production of white sugar, etc. 2. AC in different forms (granular, extruded, fiber or cloth) is used for production of pure gases in the chemical industry, to reduce pollutant gases to very low concentrations in a single stage, in protection against poisonous gases, in air conditioning, for removal of oil from compressed air, to separate gases in mixtures by sieving, etc. 3. Carbon materials have been used for some time in heterogeneous catalysis, acting as direct catalysts or as a catalyst support. Catalytic particles can be supported within the porosity to promote required catalytic conversions [8-10]. Activated carbon is a microcrystalline form of carbon with very high porosity and surface area. It may be visualized as foam solid that has a large surface within a rigid granule or particle structure of relatively small volume. Its chemical structure allows it to preferentially adsorb organic materials and other nonpolar compounds from gas or liquid streams. Activated carbon has become one of the most technically important and most widely used adsorbents because of its high adsorptive capacity. Present technology demands a very large production of activated carbons with appropriate characteristics for each particular application. In general, activated carbon which is used in any of the most common applications must have adequate adsorptive capacity, chemical purity, mechanical strength, etc. Furthermore, all these specifications should coexist with a low production cost. Activated carbon is obtained from a carefully controlled process of dehydration, carbonization and oxidation of organic substances. It can be prepared for research in the laboratory from a large number of materials. However, the most commonly used ones in commercial practice are peat, coal, lignite, wood and agricultural by-products such as coconut shell, almond shell, rice husk, etc. Pyrolysis of the starting material with exclusion of air and without addition of chemical agent usually results in an inactive material with a specific surface area of the order of several m2/g and low adsorption capacity. One can prepare carbon with a large adsorption capacity by activating the carbonized products with a 37
reactive gas. The majority of activated carbon used throughout the world is produced by steam activation (physical activation). In this process, the carbonized product is reacted with steam over 900 oC. Another procedure used in the production of activated carbon involves the use of chemical activating agents before the carbonization step. The most commonly used activating agents are phosphoric acid, zinc chloride and salts of sodium and magnesium etc. Chemical agents act as dehydration agents and they may restrict the formation of tar during carbonization. Chemical activation is usually carried out at lower temperatures than the simple pyrolysis and the activation process with steam or carbon dioxide. The production at lower temperatures promotes the development of a porous structure because under these conditions elementary crystallites of smaller dimensions are formed [11-12]. Most of the available surface area of activated carbon is nonpolar in nature. However, during production the interaction of surface with oxygen produces specific active sites giving the surface of slightly polar nature. As activated carbon is one of the most commonly used adsorbents in many industrial applications for its adsorptive capacity. In this study, production of activated carbon from apricot stones and the quality of the products have been investigated. Carbon adsorbents tend to be hydrophobic and organophilic [13-14]. According to the IUPAC definition, pores can be distinguished in three groups with respect to their dimensions. Macropores – Pores with larger than 50 nm; Mesopores – Pores with diameters between 2 nm and 50 nm; Micropores – Pores with diameters less than 2 nm. Most activated carbons contain pores of different sizes: micropores, transitional mesopores and macropores. Therefore they are considered as adsorbents with wide variety of applications (Figure 5). Microporous carbons have a unique structure which essentially is a three dimensional network, or labyrinth of carbon atoms some in hexagonal arrangements and some as individual carbon atoms bonded together extremely close but not close packed. This bonding arrangement results in space existing between the atoms to create an interconnecting three dimensional passage way in which every space unit has a connection to all others within the carbon. The dimensions 38
of the passage way (width) are those of molecules, about 0.5 nm, such that any molecule which enters into this space is subjected to intense dispersion forces from the carbon atoms (about eight per space) which make up the “surface” of the space.
Figure 5 – Classification of pore size 
These forces can “trap” the molecule for periods of time much longer than on an open surface and so the phenomenon of physical adsorption of gases is generated. The site, place or space where a molecule can be trapped (adsorbed) is called an adsorption site. These adsorption sites can be modified in terms of their size (widened or narrowed) and in terms of their chemical composition . The surface can be bonded to hydrogen, oxygen, chlorine, nitrogen, etc. to alter the polarity of the surface. Changing this polarity can enhance the adsorption process for polar molecules. The porosity can be widened by gasification with water vapor, oxygen or carbon dioxide. The parent materials may also be impregnated with zinc chloride, potassium hydroxide or phosphoric acid, these treatments improving adsorption characteristics, a process known as activation. The variables, within an adsorption system (dominantly an aqueous solution) controlling extents of adsorption include [17-18]: 1. Volume of narrow micropores, < 0.7 nm (VNM – cm3/g), including the pore-size distributions. 39
2. Volume of wider micropores, 0.7-2.0 nm (VWM – cm3/g), including the pore-size distributions. 3. Volume in mesopores, >2.0 and 7500C. 6. The effects of additions of surface oxygen complexes upon pore volumes and pore size distributions (pore dimensions can be reduced). 7. The characterization of surface oxygen complexes. 8. The pH of the solution. 9. Ionic strength. 10. Temperature. Nowadays in Kazakhstan the necessity of creation of carbon materials with high sorption properties has come. A pioneer in this field was “Laboratory of carbon nanomaterials” at the Institute of Combustion problems and at Al-Farabi KazNU created by Professor R.M. Mansurova. In this laboratory from waste rice grinding production by carbonation the first carbonized carbon biomaterial was obtained which has the ability to adsorb not only molecules, but even whole microbial cells. In the work [19-21] on the carbonized carbon material from rice husk cells of the following microorganisms: rhodotorula, glutinis var, glutinis, pseudomonas aeruginosa, pseudomonas mendocina were sorbed. The choice of these microorganisms was due to the fact that they are widely used for detoxification of sewage. In this work we have obtained very interesting results. It is shown that microorganisms adsorbed on carbon materials remained viable in the presence of highly toxic ions of cadmium, lead and copper [22-24]. If you apply the available microorganisms in the presence of these ions in a day only 20% of the total number of introduced microorganisms remains, whereas the number of living microorganisms adsorbed under the same conditions was 80 %. That is sorption of microorganisms in the 40
carbon sorbent from rice husk four times increased the viability of the microorganisms in the presence of toxic ions, in this case the total sorption capacity of these toxic ions increased several times. All these results suggest that unusual carbon material with sorbed living cells of microorganisms was created and it has the ability to high sorption of highly toxic ions. This new material can be widely used for industrial detoxification of polluted water contaminated with heavy metal ions. In this laboratory headed by Professor R.M. Mansurova, carbon materials have been created by carbonization of the waste from local raw materials. Interesting work has been done on the sorption of toxic ions by obtained carbonized carbon materials derived from rice husk and wheat bran [25-26]. It is stated that activation of the obtained carbon materials with hydrogen peroxide and ammonia significantly increases the sorption capacity for heavy metal ions and radionuclides. Thus, developed on the basis of vegetative raw materials of Kazakhstan carbonized carbon materials have a great potential for detoxification of water contaminated with ions of heavy metals and radionuclides. Moreover, they offer the prospect of using these materials for the enrichment of rare and expensive metals. Owing to excellent sorption quality of such materials it is necessary to expand and deepen the study on the creation of properties of new carbon materials derived from the vegetative raw materials of Kazakhstan . Nanostructured carbonaceous materials are produced and used as sorbents of general and selective purposes [28-38], hydrogenation catalysts and cathode materials for production of lithium batteries. In this work [39-43], a promising new material based on carbonization of apricot stones is obtained. Synthesis of nanomaterials is carried out by the methods of carbonization plant and carbonization of minerals [44-47] raw materials under various temperature conditions, using different catalysts, as well as in flames, at the facilities of various types. This material is characterized as a partially graphitized system with low crystallinity. The initial loss of the battery capacity based on a new electrode material is due to formation of a protective layer on the electrode surface which protects the anode from further destruction. The new anode material showed stable performance during prolonged cycling. Furthermore, this material showed 41
excellent compatibility with the electrolyte based on propylenecarbonate even at relatively high current densities. Further improvement of the performance of the material can be achieved by increasing its dispersion and surface modification of the anode. There also have been studied the processes of carbonization of mineral raw materials (Tonkereys, Chilik, Narynkol, and Saryozek clay) [48-49]. The degree of water purification from ions of lead reaches 85.2 %, copper ion – 94.4 %, and 98.4 % of nickel ions. In the case of carbonized vegetative raw materials the situation is as follows: the concentration of metal ions in water is from 9 to 7 µg/ml, the degree of sorption of lead carbonized by walnut shells is up to 93 %, nickel – 68 %, cadmium – 70 %, and cobalt – 83 % [50-51]. The main trends of development in science and technology is currently focused on the study of nanoscale structural components of matter and functional materials. Progress in this area is of great theoretical and practical importance because such materials can be widely used in ecology, biology and medicine and just because in these areas of science the greatest social and economic effect from the introduction nanomaterials is predicted. It should be noted that prospects for practical use of nanostructured sorbents are obtained by high temperature carbonization of cheap secondary vegetative raw materials. Carbon obtained by the carbonization of plant materials, keeps its original finely organized structure. By varying the conditions of carbonization, it is possible to obtain a complex of compositions of carbon from other materials. Some of these materials can find practical application. Availability and annual renewability of raw materials, low content of mineral impurities, developed porous structure, ecological production allow to obtain cheap, fast regenerable carbon sorbents [52-54].
2.1. Activated carbon based on raw materials A typical carbonization scheme with the following physical activation comprises raw materials preparation stages (separation, drying, cleavage), coking (carbonization without access for air) . The chemistry of pyrolitic processes during carbonization is extremely complex and not fully clear. The main task of the 42
carbonization stage is the removal of easily fugitive components, the maximum increase of carbon density and obtaining of a material with a sufficiently large specific surface and porosity [56, 57]. We would only note that the general thermodynamic analysis of the pyrolysis of carbon-containing materials allows to distinguish three main groups of processes and mechanisms: 1) cracking and dehydrogenation reactions of non-aromatic molecules; 2) cyclization of hydrocarbon chains with n ≥ 6 in the aromatics with the side chains interruption; 3) polycondensation of the aromatics in more stable polynuclear arenas. Together these cleavage (destruction) and synthesis with the recombination (consolidation) reactions lead eventually to accumulation of flat formations of hexagons, structural elements of graphenes. At the same time, these reactions are accompanied by the educing of auxiliary gaseous products entrapping the part of the carbon. More complex transformations happen to the carbohydrate part of vegetable raw materials. The articles [58, 59] show a flow chart of possible chemical reactions behavior of cellulose during the activation. From the flow chart of chemical transformations during the activation presented in Figure 6 it is apparent that ctivation proceeds in four stages. During the first stage (T=25-150 °C) predominantly the process of moisture desorption from the surface takes place. Also, dehydration due to formation of water from hydroxyl and hydrogen groups and the growth of the local ordering of macromolecules mutual arrangement may occur. The processes proceeding at this stage are reversible. The second stage occurs in the temperature interval 150-240 °C and is accompanied by the intramolecular dehydration forming bonds –C=O and –C=C-. The temperature interval 240-400 °C corresponds to the third carbonization stage. In this temperature range macromolecules degradation processes proceed as the result of the destruction of 1,4 glycoside, cyclic –C-O-C and part of –C-C bonds according to the radical mechanism. These processes lead to the decomposition of the initial polymer to separate “rings” with the consequent formation of fragments C4 (-CH =CH-CH=CH-). Simultaneously with dehydration depolymerization competing reactions are possible resulting in the formation of levoglucosan. 43
Figure 6 – Scheme of chemical transformations during carbonization of cellulose 
It dramatically increases the yield of volatile resinous matters and reduces the final carbon content. During this stage the selection of various products including aromatic proceeds. The main processes of the fourth stage which proceeds in the temperature range 400-700 °C are aromatization with hydrogen evolution and condensation of fragments C4 in the “carbon polymer”, i.e. in turbostratic carbon layers. Condensation of the C4 fragments may occur according to two possible schemes: “longitudinal” and “transverse”. In the case of the “longitudinal” scheme C4 fragments link up forming a polymer chain. Binding of neighboring chains leads to formation of graphite-like layers. In the case of the “transverse” polymerization each fragment links up with its “copy” forming a carbon chain which grows in the transverse direction. Interaction of the neighboring chains creates new layers. All this indicates the complexity of processes occurring during the pyrolysis of even, such a “model” system as cellulose. In spite of nearly identical chemical composition the cellulose samples of different origins may be very distinct in structural and textural characteristics. It is natural to assume that the behavior of carbonization processes for plant samples of various types is much more complex and under the same conditions differs both well in the composition of products educed during pyrolysis and contained in the carbonized sample and as in structural characteristics of the carbonated coal. Nevertheless, the results of the elemental GC-MS analysis, the studies of sample mass changes during the process indicate that the process of carbonization of rice husk and apricot stones generally fits into the above-described scheme and is characterized by chemical transformations presented in Figure 6.
2.2 Characterization of pores in carbon materials Pores in carbon materials have been identified by different techniques depending mostly on their sizes. The techniques for identification of pores in carbon materials are summarized Figure 7. Pores with nano-meter sizes, i.e. micropores and mesopores, are identified by the analyses of gas adsorption isotherms, mostly of N, at 77 K. Other gases, such as CO2, H2, H2O, Ar and CH4 are also 45
used. For the analysis of adsorption/desorption isotherms of gases, different methods have been proposed to extract pore structure parameters, named as BET, DFT, t-plot, BJH, HK,etc. these pores detected by gas adsorption are only open pores. If some pores are too small to accept gas molecules, however, they can not be detected as pores by the adsorbate gas molecules. In other words, these pores are closed pores, which are sometimes called latent pores. By using gases with different molecular sizes, therefore, molecular sieve performance of porous carbons has been evaluated. The fundamental theories, equipments, measurement practices, analysis procedures, and many results obtained so far by gas adsorption have been reviewed in different publications. Small – angle X-ray scattering has an advantage to identify the closed pores, together with open pores. For macropores, mercury porosimetry has been frequently applied, but great care has to be paid to apply this technique to fragile carbon materials as exfoliated graphite. Identification of intrinsic pores between hexagonal carbon layers, interlayer space, in carbon materials, is carried out by X-ray diffraction. The use of internal standard of silicon is emphasized to be essential for accurate determination of the width of these pores. Recently, direct observation of pores on the surface of carbon materials was reported by using microscopy techniques, such as scanning tunneling microscopy (STM) and transmission electron microscopy (TEM) for micropores and mesopores and scanning electron microscopy (SEM) and optical microscopy for macropores. In order to evaluate pores, a large number of observations and statistical treatment are essential, coupled with image processing technique. By these techniques, not only the pore size and its distribution but also the shape and area of pore cross-section and smoothness of the pore wall can be evaluated [62- 64].

Scanning tunneling Detect only pore entrances on the surface. Give microscopy morphological information of the pore entrance. Need statistical analysis with criteria. Scanning electron microscopy Detect only macropores Mercury porosimetry Defect mostly macropores. Difficult to apply for fragile materials.
STM observation gives only information of the entrance of pores on the physical surface of samples. For a quantitative assessment of these pores, criteria for the definition of pores have to be set up in order to distinguish them from depressions on the surface. The following two criteria were used, for example, in the analysis of the pore formation on the surface of glasslike carbon spheres during air oxidation: 1) pore wall must be so steep that its slope must be more than unity, and 2) pore must be so deep that the tip apex of the microscope can not reach its bottom. Defect formation by oxygen plasma treatment and ion bombardment was studied on the basal plane of natural graphite by STM observations. In a TEM image, taken on thin section with sufficiently high magnification, pores can 48
be recognized. Detailed studies were carried out mainly on activated carbon fibers by applying Fourier transformation on TEM images. SEM was successfully applied to characterize rigid intraparticle pores in worm-like particles of exfoliated graphite. For this observation, a novel procedure had to be developed to prepare the fractured surface of worm-like particles along the exfoliated direction. Distributions of cross-sectional area, lengths of major and minor axes, aspect ratio, and fractal dimension were determined as a function of exfoliation conditions. For flexible interparticle macropores in exfoliated graphite, the process consisting of impregnation of paraffin, thin-sectioning, and then transmission optical microscopic observation was successfully applied. Macropores in isotropic high-density graphite were analyzed on their polished cross-sections observed under optical microscope. Relationships of pore structure parameters determined through image processing on optical micrographs to mechanical properties of isotropic high-density graphites were discussed [65, 66].

OBTAINING OF ACTIVATED CARBONS BASED ON VEGETABLE RAW MATERIALS AND RESEARCH METHODS 3.1. Activation process of raw materials In this work, a series of experiments on the physical and chemical activation patterns of raw materials was performed. Physical activation of raw materials samples was performed in a rotating stainless steel reactor of 0.5 dm3 at 19 rpm. Carbon dioxide gas, was chosen as an activating agent which is supplied from the bubbler into the reaction zone at a rate of 50 cm3/min. Carbonization was carried out in a horizontal pyrolysis installation with adjustable electric heating (Figure 8) in the temperature range from 400 to 900 °C, duration 1 hour after carbonization yield at a predetermined temperature. For the experiment, crushed walnut shells, highlighting the sieving of the product of crushing the working fraction with a diameter of 2-4 mm .
Figure 8 – Setting the carbonization of vegetable raw materials
Activated carbon (AC) does not just happen; it has to be synthesized. The porosities of carbon, as initially prepared by carbonization, are not sufficiently developed for most applications and some amelioration is a prerequisite step. This is done in several ways involving creation of further porosity, widening of existing porosity, modifications to the surfaces of porosities and also modifying the carbonization process itself. There are two industrial processes used to maximize the adsorption potential of carbonaceous material.
3.1.1 Physical activation of raw materials Thermal or physical activation is a process of selective gasification (removal) of individual carbon atoms. Physical activation is carried out using either carbon dioxide or steam or mixtures of these two gases. Carbon atoms can be removed from within porous carbons by gasification using carbon dioxide or water vapor, usually at 800-900 oC according to the following stoichiometric equations, equation I and II. Activation by carbon dioxide and steam produces carbons with different porosities. 2C + 2H2O 2CO + 2H2; C + H2O CO + H2
H +159 kJmol
H +117 kJmol
3.1.2 Chemical activation Chemical activation is a process of co-carbonization by additions of such material as phosphoric acid (H3PO4), or zinc chloride (ZnCl2) or potassium hydroxide (KOH) and potassium carbonate (K2CO3). Mechanism for these activations is all different, with zinc chloride promoting the extraction of water molecules from the lignocellulosic structures of parent materials, and phosphoric acid combining chemically within the lignocellulosic structures. There is no selective removal of carbon atoms as during physical activation and carbonization yields are improved. 55
As some industrial adsorption processes require “fine-tuning” of the porosity of a carbon, it is possible to combine thermal and chemical activation processes to obtain a desired activated carbon .
Figure 9 – Installation for chemical activation of vegetable raw materials
3.2 Methods of studying the physicochemical properties 3.2.1 Fourier – IR spectroscopy FTIR spectra were recorded using specially pressed tablets consisting of KBr, and the test substance previously crushed to obtain a fraction of ~ 50 microns. Measurements were conducted in the wave number range 4000-450 cm-1 at room temperature on the device «Spectrum 65” of the firm PerkinElmer.
3.2.2 Method of scanning electron microscopy Research of surface morphology in the obtained samples were carried out on a microscope QUANTA 3D 200i (FEI, USA) with an accelerating voltage of 30 kV, Figure 10. 56
The samples were fixed on a copper holder with a conductive glue or tape. Previously on the sample surface in a special vacuum system Zeiss Sigma, using emission gun SEM (Zeiss NTS) with an accelerating potential of 5 kV was applied to the conductive thin platinum layer thickness of 4 nm to eliminate charging effects.

3.2.3 The method of low-temperature nitrogen adsorption Information on the micro-mesoporous texture (area of 17 to 3,000 Ǻ) samples of carbon materials was obtained by lowtemperature nitrogen adsorption-on device Autosorb 1 (Quantachrome, USA) after preliminary treating samples and 150200 0C performed at a residual pressure of less than 0.001mer.colmn, Figure 11. Further, measurements of adsorption isotherms of nitrogen were made at liquid nitrogen temperature, 77 K, in the range of relative pressures between 0.005 and 0.991 and their standard processing using the theory of BET (Brunauer-Emmett-Teller) for calculating the total specific surface area SBET; on the model of Barret-Joyner-Halenda (BJH), the adoption of a conditional model of cylindrical pores to calculate the volume of mesopores (Vmeso) and average pore diameter (dav); by the method of Dubinin-Radushkevich (DR) to calculate the volume of micropores (Vand also on the method of DFT (Density Functional Theory – DFT) with the 57
adoption of models of slot / cylindrical pores (QSDFT) for calculating the specific surface area (SDFT) and pore volume (VDFT). Accuracy of the method is 10%.

3.2.4 Аutomated mercury porosimeter The pore structure of activated carbon materials has been investigated using a mercury porosimeter PoreMaster (Quantachrome Instruments, USA), Figure 12. The operation of all mercury porosimeters is based upon the physical principle that a nonreactive, non-wetting liquid will not penetrate into fine pores until sufficient pressure is applied to force its entry. The relationship between the applied pressure and the pore diameter into which mercury will intrude is given by the Washburn equation: D = (-4γ cos θ)/P, where P is the applied pressure, D is the pore diameter, γ is the surface tension of mercury (480 dyne cm-1) and θ is the contact angle between mercury and the pore wall, usually taken as 140º. Monitoring mercury volume intruded as a function of pressure permits the generation of pore size/volume distributions from the Washburn equation.

3.2.5 Sorption activity of methylene blue on activated carbon Before carrying out the analysis standardized test solutions were prepared for the construction of the calibration curve. Construction of the calibration curve. Blank solutions are prepared for the construction of calibration curve. For this purpose in 10 volumetric flasks of 50 ml each, 0.5; 1.0; 1.5; 2.0; 3.0; 4.0; 5.0; 6.0; 7.0; 8.0 ml of methylene blue (MB) solution (1500 mg/l) are infused, then the volume is made up to the mark with water at a temperature of 20 ± 2 °C. The obtained solutions contain 1l, respectively, 15; 30; 45; 60; 90; 120; 150; 180; 210; 240 mg/l. Optical density of the obtained blank solutions is measured on photoelectric colorimeter with a blue colour filter with a wavelength of (λ) of 400 nm in cuvettes with the distance between the active faces of 10 mm. Distilled water is used as a test solution. According to the obtained data the calibration curve of optical density dependence on the concentration of the blank solution is constructed. The data on the dependence of optical density on the concentration of the calibration solutions of MB. Carrying out an analysis. Approximately 0.1 g of carbon, predried and crushed in an agate mortar, is weighed with an accuracy of less than 0.001 g. A weighed sample of carbon is placed in a conical 59
flask of 50 ml with addition of 25 ml methylene blue solution (1500 mg/l), stoppered and stirred for 20 minutes. After shaking, the carbon slurry is transferred to a centrifuge tube and centrifuged for 15 minutes, 5 ml of clarified solution gently pipetted, and its absorbance is determined on the same photoelectric colorimeter. If the optical density of clarified solution is greater than 0.8 absorbance units, then 5 ml of this solution is transferred into a volumetric flask of 25 ml or 50 ml, depending on its optical density. The solution in the flask is diluted with distilled water up to the mark. The optical density of the solution after dilution should be from 0.1 to 0.8 absorbance units. The dilution factor in this case is equal to 5 or 10. Upon optaining of the value of optical density, using the calibration curve the residual concentration in the methylene bleached solution is determined. Activated carbon adsorption of methylene blue (X) in milligrams of methylene blue per 1 g of activated carbon is calculated by the formula: Х = 0.025* (С1 – С2*К) /m
wherein: С1 – concentration of original dye solution (1500 mg/l); С2 – concentration of the solution after contacting with carbon, mg/l; K – dilution factor taken for analysis, after contacting with carbon (if necessary, the solution is diluted 10 times); m – mass of activated carbon weighed portion, g (≈0.1 g); 0.025 – amount of methylene blue solution, taken for lightening, l. For the analysis result, the arithmetic mean of two parallel determinations is taken, permissible differences between them should not exceed 10 mg/g.
3.2.6 Chromatographic separation of fusicoccin For the experiment, 1 kg of seeds of spring wheat cultivar “Steklovidnaya-24” was taken. The seeds which were soaked for one day in a sterile cool tap water supplemented with 1 mM 6-BAP (6benzyl aminopurine). 6-BAP was added as an inducer of the BS. Then germinated seeds were homogenized in 3 liters of 70% ethanol on the blade type homogenizer MPW-302 (Poland). The homogenate 60
was centrifuged for 10 minutes at 10,000 x g. The resultant alcoholic extract was purified by column nanostructured carbon sorbent of size ø 3 cm by 20 cm which was previously equilibrated with distilled water. In the column was applied to 100 ml of alcohol extract. Then to completely remove unbound materials the column was washed with 200 ml of 10% ethanol, desorption of BS was conducted with 50% ethanol, then for complete removal of all substances that final column was washed with 96% ethanol. Sorption and desorption were carried out on a glass column of their own manufacture, control of the elution was carried out on type UV monitor Uvicord SII manufactured by LKB (Sweden). In the presented work was used a column manufactured as follows (Figure 13).
Figure 13 – The apparatus UV detecter connected with column chromatography
For a glass tube a rubber tube so of the desired size was selected that it enters the tube only half or less. Then, with the narrow end of the plug blade we chose gentle concave surface, deepening the center plug, and then polishing the surface with sandpaper and the exact center of the plug was inserted into the plastic nozzle or syringe with a diameter of 1.5-2.5 mm. The nozzle must be inserted so that one end accounted for exactly the bottom surface of the funnel, and the other free exit from the wider end of the plug. If possible, it is desirable to have a plastic plug screw thread, which can be tightly 61
screwed to various connecting plastic tubing or plug. After making the bottom plug with a hose, the narrow end of its snug nylon fabric (preferably from the children’s bow) was inserted into the cork with a cloth in the lower end of the column. After the plug firmly, but not much comes to a column sticking out of the column pieces of nylon fabric carefully cut with a razor cap more tightly planted on the column and the column was checked for leaks. It was very convenient to use the plug with the union in the upper part of the column. In this case, the cut surface of the funnel is not necessary, and the nozzle or needle is located on both sides of the plug. The top tube provides complete sealing of the column and continuity in the elution solution from a supply vessel with a minimum hydrostatic pressure .
3.2.7 High performance liquid chromatography (HPLC) HPLC is basically a highly improved form of column chromatography. Instead of a solvent being allowed to drip through a column under gravity, it is forced through under high pressures of up to 400 atmospheres, Figure 14. That makes it much faster.
Figure 14 – High performance liquid chromatography
It also allows to use a very much smaller particle size for the column packing material which gives a much greater surface area for interactions between the stationary phase and the molecules flowing past it. This allows a much better separation of the components of the mixture.
3.2.8 The mass spectrometric analysis method Mass spectrometric analysis of chromatographically extracted compounds was performed on an apparatus Agilent 1100 mass spectrometer trap Esquire 3000 plus. Type ionization – electrospray, flow rate 0.4 ml / min., Temperature – 35 0C. The total time of the experiment was 25 minutes. HPLC conditions: 2 minutes – 10% AcN, 100 minutes – 100% AcN, 15 minutes – 90% AcN, 18 minutes – 80% AcN, 21 minutes – 50% AcN. This method is based on chromatographic separation of peptides (fragments in solution) on column converts an RP-18 phase. Pre-dried sample was diluted by a buffer containing 10% aqueous solution of formic acid. The measurement error is 3%. A separation method using LC-MS with stationary phase using fused core particles has been developed. The column was an Ascentis®Express C18 (2.1mmx100cm, 2.7 μm). The advantages of that type of stationary phase is that it provides high peak efficiency, equivalent to a stationary phaste if 1.7 μm particles, but with the need of less inlet pressure. The fragmentation of fusicoccin with multistage mass spectra (MS2 and 2 independent fragmentation pathways in MS3) with an ion trap have been studied to provide a reliable identification even in presence of possible interferences from the matrix. We have attempted to identify fusicoccin in ethanol extracts obtained from wheat (solid extract) and in these extracts spiked with standard.
3.3 Synthesis of carbon sorbents and using for fusicoccin extraction, experimental results and their discussion 3.3.1 Computer modeling of activated carbon for fusicoccin We have retrieved an X-ray structure of fusicoccin from the Brookhaven Protein Database (entry 3IQV) and optimised its geometry using molecular mechanics (MMFF) followed by semiempirical calculations (PM3). The size of the molecule (to its van der Waals limit) is about 1.9 x 1.5 x 1.1 nm. As it can rotate freely in solution it is unlikely to be bound within pores that are smaller than the compound’s largest dimension. Overlaying the molecule on a model of a graphene sheet and removing carbon atoms until fusicoccin just fits leaves a pore just over 2.1 nm in diameter. To allow for any solvent and rapid molecular rotation, we would suggest a pore size of 2.5 nm as the minimum that could be expected to bind the molecule.
Figure 15 – Microporous activated carbon and fusicoccin molecular
According to the results of computer modeling, cleaning composite components of fusicoccin using microporous carbon adsorbents not suitable as the size of the molecule of fusicoccin more than micropores. And in the following figure (Figure 16) the optimum pore size for purification of constituents of fusicoccin was determined by computer simulation. When cleaning the composite components of fusicoccin using microporous carbon adsorbents, computer modeling was first used.
Figure 16 – The optimal pore size of carbon for column chromatography
As the results of computer simulation in this work study show that the most effective recognized mesoporous activated carbons.
3.3.2 Determination of specific surface area of samples of carbon materials Sorbtometre-M Summary thermal desorption method is that a mixture of argon with carrier gаs of helium uptake of argon the sample is cooled to liquid nitrogen temperature. Cooling reduces the concentration of argon in the mixture flowing through the meаsuring cell detector that registered the adsorption peak by potentiometer and noted it on a chart. After determining the adsorption equilibrium the sample is 65
heated to room temperature. Concentration of argon аs a result of desorption increаses, and this change in the concentration is recorded on the diagram аs a peak of desorption, directed in the opposite side with respect to the peak of adsorption. The square of obtained peaks are proportional, respectively, the adsorption and desorption amount of the argon. The calculation of the specific surface area of the sample is made by area of desorption peak, like less blurred, using the calibration graph constructed in the coordinates: the peak area related to the hitch, the specific surface of adsorption m2/g. Investigated the specific surface of samples obtained vapor-gаs and chemical (phosphoric acid) activation WSh-600, RH-900, АS600, АS-500, WSh-600. Table 2 shows the data obtained by device Sorbtometer-M. Table 2 The data on the specific surface area of the samples of carbon materials Sample WSh-600 RH-900 АS-600 АS-500

Terms passage of the activation process of carbon materials have been selected in such a way that after activation the carbon material had a high surface area and save a high mechanical strength. Previously, it was found that treatment of carbon materials with inorganic activating reagents was followed by the increase in their specific surface area to 1000 m2/g. Changing the ratio of the activating reagent and the activation temperature rise to 950 °C leads to the fact that the reaction of carbonization proceeds simultaneously with oxidation of the material. The combined influence of two processes leads further to the growth of the specific surface to 12002100 m2/g (Table 4), however, it reduces the mechanical strength of the samples.

3.3.3 Methylene blue adsorption As a result, activation of raw materials significantly changed the value of specific surface area and sorption capacity (Table 6). If before activation the samples have sorption capacity by the methylene blue 0.07-0.10 cm3/g, after activation the samples showed sorption capacity of 268.75 – 400 mg/g. Some activated carbon had a mesopore (2 to 5 nm) structure which adsorbs medium size molecules, such as methylene blue. Thus, the quantity of methylene blue which is adsorbed onto absorbent also indicated the number of mesopore.

3.3.4 The investigation of physico-chemical properties of the obtained nanoporous carbon sorption materials. Selection of the optimum conditions for obtaining modified sorption materials To reveal the morphological and structural features of carbon materials, the method of electron microscopy was used. Investigations were carried out on the microscope Quanta 3D 200iDualSystem, FEIso with the built system of energy-dispersive microanalysis. As seen in Figure 19-22, all the samples of the carbon materials have non smooth and rough surface with a high porous structure. As seen from the photomicrograph the increase ratio of activating reagent destroys the porous structure and reduces the mechanical strength of the samples. With the help of modern energy-dispersive spectrometer of the type Jidda-2300 EDS company «JEOL», Japan, which is an additional device of scanning electron microscope the elemental composition of the carbon samples was determined before and after activation. The results of these studies are presented in Table 8.

Table 8 shows, cetonitrile resulted in a substantial reduction of the amount of oxygen and sulfur, which are volatilized during carbonization, this beneficially affecting the quality of the carbonized material. If before carbonization the content of carbon is 62%, after carbonization it is 91%.
3.3.5 The study of sorption characteristics of carbon materials One of the tasks was to control the texture-sorption characteristics of the materials produced – namely, the mesopore volume according to mercury porosimetry, the nature of nitrogen 72
adsorption isotherms and pore size distribution, surface area, volume and average pore diameter. During the work samples of activated carbon from rice husk, walnut shells and apricot stones were synthesized. Samples AS-500, AS-600 and AS-700 were obtained by carbonization in current of argon for 1 hour at temperatures of 500, 600, 700 °C, respectively. Activated carbons (CRH – 600, 700, 800, 900) have been obtained by carbonation in the current of argon for 1 hour at a temperature corresponding to the indices of samples, followed disilication 1M NaOH. In Figure 23 shown a graph of pore size distribution of samples from apricot stones at 500 0C according to the mercury porosimetry. In Figure 24 shown a graph of pore size distribution of samples from apricot stones at 600 0C according to the mercury porosimetry.
Figure 23 – The pore size distribution of samples from apricot stones at 500 0C, according to the mercury porosimetry
According to the mercury porosimetry, in all samples of carbon materials derived from apricot stones, peaks are observed in the range of pore distribution of from 7 to 15 nm, indicating that the mesoporous materials, although substantial amounts of pores attributable to a range of 70 to 100 nm for sample AS-500 and 100 to 300 nm for the other samples correspond to small macropores. 73

In Figures 26-29 shows the pore size distribution of samples of rice husk obtained under various temperature settings in a stream of argon.

Figure 29 – The pore size distribution of samples of rice husk, at 800 0C, according to the mercury porosimetry
From the presented curves of pore size distribution (Figures 31 and 32) it is seen that the samples obtained from carbonized rice husk by leaching silica are more meso and macropores, as compared 76
with samples of apricot stones, and have pores in the range of 7 to 80 nm. In Figure 30 shows the pore size distribution of samples from walnut shells, obtained at 700 0C degrees under argon. From the presented curves of pore size distribution (Figure 30) follows shows that the sample obtained from carbonized walnut shells by physical activation, have more meso pore compared with samples of apricot stones and rice husk, and have pores in the range from 1 to 7 nm. Further study of porous samples were performed by lowtemperature nitrogen adsorption for the best carbonized samples from rice husk and apricot stones.
Figure 30 – The pore size of the carbon material from walnut shells
Table 9 shows the values of textural properties of the samples according to the low-temperature nitrogen adsorption. Standard processing was performed by the BET method using a conventional cylindrical pore model (BJH) with the calculation of the total specific surface area, total pore volume; dav median pore diameter (based on micro- and mesopores), and density functional theory (DFT) with calculation with a total specific surface area, total pore volume.

The table also shows the data on the volume of pore according to the mercury porosimetry.
Figure 31 – The isotherms of adsorption and desorption of nitrogen samples AS-500
From the above table it follows that the sample of AS-600 has a higher BET specific surface area (393 cm2/g) and pore volume than the sample of AS-500, due to the higher temperature carbonization. The sample CRH-800 has a surface area of 641 cm2/g BET, and a large pore volume according to mercury porosimetry, which corresponds to the graph of the distribution of pore sizes (Figure 29). Figures 32-34 shows that the adsorption / desorption isotherms of nitrogen, which are classified by the International Union of Pure and Applied Chemistry (IUPAC), belong to the first type. 78
In Figure 32 presents the isotherms of adsorption and desorption of nitrogen samples AS-500. In Figure 33 presents the isotherms of adsorption and desorption of nitrogen samples AS-600. In Figure 33 presents the isotherms of adsorption and desorption of nitrogen samples CRH-800. According to the method of nitrogen adsorption the method accounts for the largest number of pores per mesopores, evidenced by the results of measurements of the surface of the pore volume and shape of the hysteresis loop of the formed isotherms. For samples AS-500, AS-600 and CRH-800 were built nitrogen adsorption isotherms as shown in Figure 34.

The adsorption isotherm of nitrogen and water of the sample WSh are shown in Figure 35. 80
1 adsorption-desorption of liquid nitrogen, 2 adsorption-desorption of water Figure 35 – The adsorption isotherm of nitrogen and water on the sample WSh
When considering the isotherms of adsorption-desorption of nitrogen, it turns out that there occurs a capillary condensation, due to the presence of mesopores (2-50 nm) in material of walnut. This is evidenced by the shape of the hysteresis loop formed by the adsorption and desorption branches of the isotherms that classification BDDT refer to the 4th type, characteristic of the micromesoporous materials. – Water contains information about the surface chemistry of the sample (but nitrogen can not). - The kinetic diameter of water molecules is less than that of nitrogen molecules, so water can pass more deeply into the very small micropores. On the other hand, water can fill only small mesopores (while nitrogen may completely fill mesopores (2-50 nm)). Figures 36-38 shows the differential pore size distribution in the samples of the AS-500, AS-600 and 800-CRH. The figure shows that all samples have maximum distribution of mesopores at a pore with the diameter of 3 nm and 4, however, the samples contain a sufficiently large number of pores with sizes ranging from 4 to 16 nm. 81

3.3.6 The results of Fourier – IR spectroscopy of raw materials Very important and interesting information about the presence of various functional groups and radicals in the samples gives the IR spectrometry. Was studied the IR spectra of the carbon material, carbonized at different temperatures. The results are shown in Figures 41-44. For IR spectrum of the feedstock (crushed apricot stones) are characteristic absorption bands NH2 (3431,92 cm-1), ОН (3009,97 cm-1) group, С=О (1643,25 cm-1), С–О (1241,55 cm-1), С–ОН (1055,64-1157,28 cm-1), С=С, С=N (1662,55 cm-1) stretching vibrations of СН2 (1378,87 cm-1) (Figure 42). For the IR spectrum of the carbon material, carbonized at a temperature 800 0С, is an increase in the intensity of the characteristic absorption bands NH2, 84
СОН, С=О, ОН and absorption bands СН2 of the aromatic ring (Figure 42). The emergence of fullerenes indicates a serious restructuring in the structure of the carbonized material. These results were confirmed by direct electron-microscopic study of this carbonized material.

18.104.22.168 IR spectroscopic analysis carbonized rice husk On Figure 43 shows the IR – spectrum carbonized rice husk samples which obtained at a temperature of 700 °C, respectively. The bands of silica as well as carbon materials pyrolyzed in rice husk dominate in the IR spectrum. 700 °C temperature carbonization peaks disappear, indicating that the carbon burnup surface forms containing fragments of C-H (Figure 43). In this form of oxidized carbon with absorption at 1599, 1453 and 1383 cm-1 are present in larger quantities. The absorbance at 1599 cm-1, attributed to the C = O vibrations of a ketone and aldehyde groups. The peaks with low intensity at 1453 and 1383 cm-1 correspond to the vibrations of C-O in the carboxyl group. With increasing temperature carbonization to 700 °C, the relative intensity of the peaks at 1599, 1453 and 1383 cm-1 remains unchanged. It can be assumed that the formation of oxidized forms of surface carbon by carbonizing rice husk in these conditions occurs: by thermal decomposition of the starting fragments of cellulose, hemicellulose and lignin to form a surface of ketone, aldehyde and carboxyl groups.
Figure 43 – The IR spectra of carbonized rice husk at 700 °C
Figure 44 – IR spectra of walnut shells (t=800 0С)
By IR – spectroscopy method found the presence of carbonyl, carboxyl, hydroxyl and siloxane groups on the surface of rice husk.
22.214.171.124 IR spectroscopic analysis carbonized sorbents On the IR spectrum observed characteristic absorption bands 883 and 1050 cm-1 corresponding to C = C, deformation oscillations of C = C aromatic ring and band relating to the stretching vibrations of aromatic rings 1600, 1578 and 1510, and C-H group 3053, 3030 cm1 . By IR spectroscopy revealed the presence of structures of polyaromatic hydrocarbons. It is shown that increase in carbonization temperature increases the intensity of the bands of aromatic condensed systems, . The carbonized sorbents at temperatures 800 С, identified the following polycyclic aromatic hydrocarbons: pyrene by absorption bands (cm-1) 720, 850; crown – 547, 1320; fluoranthene – 600, 740, 820. On the IR spectra of intense absorption bands at wave numbers 1284, 1183, 577, 528 cm-1 revealed the presence of the C60 in Raman 87
spectra. Thus, the study of carbonized sorbents by IR spectroscopy revealed the presence of carbonyl, carboxyl, amine, phenolic groups, and polycyclic aromatic hydrocarbons, and structures of the fullerene. Comparing three different sorbents based on raw materials, it was stated, that walnut shells shows good results and more developing meso pore structure. So, in future work we will use walnut shells for column chromatography.
3.3.7 Extract of phytohormone of fusicoccin containing components Fusicoccin was obtained by a technique developed in the ICP, as part of the bouquet of organic compounds. In this connection, there arose the task of separation of biologically active substances. To solve this task, the technique has been used with liquid chromatography sorbent made of WSh. A distinguishing property of the selected sorbent is that it contains carbon and silica in its structure, this leading to the presence of both hydrophobic and hydrophilic properties. Supernatant – supernatant liquid resulting from the above method was placed on a column of a separating material (in this case cetonitri WSh). To control the chromatographic separation, a UV monitor type Uvicord S II manufactured by LKB (Sweden) was used. To release columns from unadsorbed substances, the column was washed with 10% ethanol to completely remove them, and then bounded with sorbent phytohormone was eluted with 50% ethanol. The spectroscopic study of purified WSh was conducted on spectrophotometer Ultrospec +1100 pro company of Amersham Biosciences (UK) in the ultraviolet and visible regions of the spectrum. Fot the test, СWSh samples obtained at temperature of 800 °C were chosen. To compare the specific characteristics, nanomaterial organic gel Octyl Sepharose CL-4B (Sweden) used in the world today was taken. The liquid containing FC was passed through a separation column with the experimental material. The results of the chromatographic separation are shown in Figure 45.
Figure 45 – Curves of chromatographic separation of fusicoccin on the column SGA-750 (a) and organic gel Octyl Sepharose CL-4B (b)
The first peak (Figure 45) contained substances that do not bind with sorbent. For release the column from unadsorbed substances, the column was washed with 10% ethanol prior to complete removal, and then the phitohormone bound with the sorbent was eluted with 50% ethanol (2nd peak). Analysis of the figures of separation suggests that the synthesized sorbent has separation characteristics which are not inferior to the world analogues. Also from Figure 45 it follows that when using a nanostructured composite material, the process of separation takes a shorter amount of time. However, the greatest advantage of this material is that it has a high resistance with respect to the microbiological media and the lack of parasitic sorption, unlike organic gel Octyl Sepharose CL-4B (b), having agarose in its structure.
3.3.8 Mass spectrometric analysis. Fragmentation of Fusicoccin using MS/MS Fusicoccin was infused with methanol at a concentration of 11.7 µg/g and a flow rate of 180 ul/h in methanol. The MS conditions are shown in Figure 46. 89

STUDY OF BIOLOGICAL AND CYTOTOXIC ACTIVITY OF FUSICOCCIN
4.1 The examination of the cytotoxic activity of the obtained fractions Objects of the study were 8 sample substances for the presence of cytotoxic activity pertaining to brine shrimp larvae Artemia salina (Leach) under cultivation conditions in vitro. Samples designation (name): 1. A0 – crude extract; 2. А1 – fraction after the preparative separation; 3. А2 – fraction after the preparative separation; 4. А3 – fraction after the preparative separation; 5. А4 – fraction after the preparative separation; 6. А5 – fraction after the preparative separation; 7. А6 – fraction after the preparative separation; 8. А7 – fraction after the preparative separation. Cytotoxicity was assessed with the help of the survival test of brine shrimp larvae of Artemia salina (Leach). Experiments were carried out in 2-day-old larvae in cultivation conditions in vitro. The larvae were grown up by dipping of brine shrimp eggs Artemia salina (Leach) into the artificial sea water and by the 48 hours incubation at a temperature of 37 0C. A weighed portion of the test sample was dissolved in 2 ml of methanol, and then it was taken from that solution by 500 μl (3 parallels), 50 μl (3 parallels), 5 μl (3 parallels). After evaporation of methanol 5 ml of artificial seawater were added to each vial. Thus, if the initial sample weight was 2 mg, the final sample concentrations were 100 µg/ml, 10 µg/ml and 1 µg/ml, respectively of each concentration in 3 replications. 10 2-dayold brine shrimp larvae Artemia salina were put into each vial containing the sample using the Pasteur pipette. Thereafter, all the vials were left at room temperature exposed to light for 24 hours. After 24 hours survived and dead larvae were counted. Then, using the obtained data of the upper and lower toxic limits a half-toxic sample dose was calculated. 99
Statistical results reporting was conducted using FNI computer program. Findings of investigations.

4.2 Antimicrobial activity tests Materials and methods: Objects of the study were 8 samples for the presence of antimicrobial activity. Samples designation (name): The study of antimicrobial activity of the samples mentioned above was performed pertaining to gram-positive bacteria strains Staphylococcus aureus, Bacillus subtilis, gram-negative strains Escherishia coli and Candida albicans yeast fungus by the method of diffusion into the agar (wells). Comparator agents were gentamicin for bacteria and nystatin for C. albicans yeast fungus. Cultures were grown in a fluid medium with pH 7.3 ± 0.2 at a temperature of 30 to 350C during 18-20 hours. The cultures were diluted 1:1000 in a sterile 0.9% sodium chloride isotonic solution; then they were put into cups with 1 ml of solution with relevant elective nutrient media for the studied test-strains and inoculated according to the method of “continuous lawn”. After drying on the surface of the agar wells of size 6.0 mm were formed, which were filled with the solution of the test sample, gentamicin and nystatin. Ethanol in equivoluminar quantities was used ss control. Thus, the sample was tested in quantity of 1 µg and the comparator agent in quantity of 1 mg. The inoculations were incubated at 37 0C, the accounting of growing cultures was performed after 24 hours. The antimicrobial activity of the samples was estimated by the diameter of test-strains inhibition zones (mm). The diameter of inhibition zones lower than 10 mm and the continuous increase in the cup were estimated as the absence of the antibacterial activity, 10-15 mm – as a weak activity, 15-20 mm – as a moderate activity, over 20 mm – as an expressed one. Each sample was tested in three parallel experiments. Statistical reporting was performed by methods of the parametric statistics with the calculation of arithmetic mean and standard error.
Findings of investigations. The results of the testing of the samples’ antimicrobial activity are listed in Table 12.

USING FUSICOCCIN AS BIOSTIMULANT (BS)
5.1 Investigation of the activity of fusicoccin using biotest Of course, any bioregulator is necessary to be examined first using biotest. Using this biotest, it is possible to determine what type of hormones among regulators relates to bioregulator. For this reason, the impact of fusicoccin on plants were investigated with multiple biotest. The exciting thing in bioassay is to destroy the influence of the apical dominance. Among all phytohormones only because of the effect of the cytokinin performed biotest. Apical dominance is characterized by the presence of the terminal bud on the stem. In case when growing indicated bud, other additional leaves can not grow on this stem. If remove this apical bud, among phito hormones may be additional leaves and shoots only because of the impacts of cytokinin. Beans were placed by 12 pieces in 3 Petri dishes, poured water was poured in a ratio of 1/3, and left in a well-lighted place, Figure 58. About 2 weeks the beans were watered, and changed the paper under the laid seeds was changed. When the beans sprouted and began to grow, were opened a petri dish, and continued to care for the plants were continued to be cared. After 2 weeks, sprouted bean seeds were placed into cups. Thus, daily pouring water on the basis, take care of the plants for 1-2 weeks, Figure 59. Then, the “apical dominance” (availability of the terminal bud on the stem), was destroyed, i.e. removed the terminal buds were removed. In case where the apical bud grows, no other additional leaves can grow on this stem. If we remove this apical bud, among plants of phytohormones only because of the impact of cytokinin there may be additional leaves and shoots.
Figure 58 – Grains of beans for biotest
To carry out this bioassay, wetted foam 50 ng/ml with solution of wheat fusicoccin, and with a piece of that foam rub the stem stepson removing the terminal bud, within 1 week once a day.
Figure 59 – Bean seeds put into the cups
To determine the efficacy of a given dose of 50 ng/ml, one specific bioassay was performed. To do this, cut the stem of a conventional flower, placed them in three different glasses, and observe the index of rooting. In the first glass there is water, in the second – fusicoccin with water in a ratio of 1: 1000, in the third – fusicoccin with water in a ratio of 1: 500.
We can make the following conclusion based on this comparison study: rooting in wheat of fusicoccin proceeds faster than in water, and optimal concentration of wheat fusicoccin is 50 ng/ml. As a result of rubbing the stem stepson within 1 week once a day with a piece of foam soaked in 50 ng/ml solution of wheat fusicoccin, removing terminal buds, we obtained the best results. This plant was growing 2-3 times faster than the beans growing on the water only, i.e. without fusicoccin.
b Figure 60 – The plant poured with: a – solution of fusicoccin; b – only with water
In conclusion, we can say that using physiological bioassay our fusicoccin can be attributed to cytokinin.
5.2 Practical application of fusicoccin The unusual properties of the biostimulator make it very promising for the rapid vegetative reproduction of woody plants with any type of root system. The use of the obtained sorbent allowed us to obtain the amount of biostimulant, sufficient for field trials. Given the harsh environmental and climatic conditions of Kazakhstan, it was very interesting to study the effect of the biostimulant on increasing the resistance to stress of the most important cereal crops of Kazakhstan. Thus, the effect of purified 108
fusicoccin on the germination of wheat seeds of the Nadezhda variety in 2% NaCl solution, i.e. under conditions simulating strong chloride salinization. It was shown that under these conditions, fusicoccin increases the germination of wheat grains by 19% by weight. The results of the experiments are presented in Figure 61.
2% NaCl + Fusicoccin
Figure 61 - Influence of a biostimulator on the germination of seeds of wheat variety “Nadezhda” in NaCl solution (2%)
As can be seen from Figure 61, seedlings on fusicoccin have a better developed root system. The use of this biostimulator for increasing winter-hardiness of winter wheat has a great prospect. The tests were carried out in the Research and Production Center of Agriculture and Plant Industry of the Republic of Kazakhstan. Table The effect of fusicoccin on yield and weight of 1000 grains of Steklovidnaya-24 winter wheat Productivity with Version 1000 grain weight 0.1 weave kg % г % control 2,950 100 43,73 100 biostimulator 3,250 110 50,41 115
As shown by the experiments, the use of fusicoccin increases a mass of 1000 grains by 15% and productivity by 10% (Table 15). In the course of further research, field tests of fusicoccin were carried out (Fig. 62). It was noted that wheat treated with a biostimulant ripened 15 days earlier than wheat without treatment (green shoots).

Plants (Fig. 62) were grown on the fields of the Republican State Enterprise "Scientific Production Center of Agriculture and Plant Growing" of the Ministry of Agriculture of the Republic of Kazakhstan (Almalybak village, Karasai district, Almaty region).
5.3 The use of BS to increase the yield of agricultural crops Given the extremely high stimulating activity of BS, it was impossible not to study the effect of BS on the yield of the most important crops. For the experiment, an aqueous solution of BS was taken at a concentration of 50 ng/ml. Seeds before sowing were soaked in this solution for 3-6 hours. After that, the seeds are dried and sown with standard tractor seeders. Field experiments were 110
carried out on sites ranging in size from 2 to 4 hectares. The experiments were conducted on the fields of the RSE "Research and Production Center for Agriculture and Plant Growing". Village Almalybak Karasay district of Almaty region. The results are presented in table 16. Table 16

The following experiment to increase the yield of winter rye was carried out on the fields of the Bishkul poultry farm on field plots, each of which had an area of 8 hectares. The results of the experiments are presented in table 17. Table 17 Increasing the yield of winter rye varieties "Sholpan" Yield increase centners / ha Version swath the average Control 19,9 20,0 20,1 20,0±0,1 Experience 27,9 28,0 28,1 28,0±0,1 Yield % 40,2 40 39,8 40±0,2
As can be seen from the table and the official act signed by the administration of the factory, pre-sowing treatment of seeds of winter rye of the Sholpan variety gave an increase of 40% to the yield.
Such a high increase in yield of winter wheat and winter rye is explained by the following reasons. The pre-sowing treatment of seeds with BS preparation significantly accelerates the development of plants and, before winter, plants of winter wheat and winter rye form the root system better and therefore overwinter better. In spring, plants with a well-developed root system make better use of soil moisture, and these plants grow better than control plants. And all this provides a significant increase in yield. Field trials of the biostimulator obtained by us were carried out to increase the yield of sugar beet. Kazakhstan provides only 10-15% of its needs with its own sugar, while the rest of the sugar is imported. And this led to more than two-fold increase in the price of sugar. The agricultural workers are tasked with a sharp increase in sugar beet production in the Republic. The use of biostimulants to increase the yield of sugar beet will play a major role in this task. Therefore, our task was to study the effect of the BS preparation on the yield of sugar beet. Field tests were carried out in the fields of the Production Agricultural Cooperative "Zher Ana" of Almaty region on an area of 2 hectares With an aqueous solution of BS preparation at a concentration of 50 ng/ml, the seeds of sugar beet were soaked for 4-6 hours; after the seeds were dried, they were planted. The results of the experiment showed that the use of purified biostimulant concentration of 50ng/ml for presowing treatment of sugar beet seeds gave a yield increase of 20% as can be seen from table 18. Table 18 Effect of BS on increasing the yield of sugar beet

Figure 63 shows the effect of presowing treatment of sugar beet seeds with a purified biostimulant on the development of a root crop. So, for example, 1 gram of BS is enough for pre-sowing treatment of seeds of grain crops sown on an area of more than 500 hectares. 112
Figure 63 – The effect of presowing treatment of sugar beet seeds on the development of the root, I-control, II-exprience
Pre-sowing treatment of grain seeds gives an increase in yield: winter rye by 40.0%, winter wheat by 33.3% and sugar beet by 20%. Presowing seed treatment accelerates ripening for half a month, winter crops, which allows you to get away from the summer drought.
5.4 Sowing varieties of tomatoes and cucumbers in the greenhouse with PMF Using as a bio-stimulator compound components fusicoccin and enriching part, a new microfertilizer phyto microfertilizer (PMF) was developed and tested in the greenhouse, in the sowing fields. Thanks to the obtained positive results, issued a Material Safety Data Sheet by Ministry of Industry and New Technologies of the Republic of Kazakhstan dated June 16, 2014 (SC-HP number 0000288) (Figure 61) was issued.

5.5 Results of laboratory and field experiments to assess the effectiveness of phytomicrofertilizer (PMF) on cereals In laboratory experiments there were determined the growth stimulating preparation and fungicidal activity at dilutions of 1:10, 1:25, 1:50, 1:100. As a reference, we take registered in Kazakhstan as plant growth regulators Russian drug biosil established on the basis of the triterpenoid acid. Seeds of wheat and barley were treated with different dilution of the original product on the basis of PMF. They germinate in Petri dishes on moist sterile sand by 100 seeds in 4 times repetition. At the 4th day it was determined vigor, on the 7th day germination and musty. In parallel experiments on laid paper rolls filled with a mixture of sand and soil in the ratio 1: 1, where the plants were grown to the phase of 2 leaves. Field experiments were laid in the Karabalyk ACES. As standards there were chemicals recommended for use on cereals in Kazakhstan. Seeds of spring wheat and barley were treated at the rate of PMF 0.2 and 0.4 l/m. They correspond to the drug dilutions 1:25 and 1:50, with the water flow rate of 10l/t for seed treatment of cereals, which is accepted in production environments. Scheme of experience: PMF – 0.4l per 1 ton of seeds PMF – 0.2l per 1 ton of seeds Vitavaks 200FF – 2.5 kg/t (etalon-1) Kinto duo – 1,5 l / t (etalon-2) Control – untreated seeds Sowing the seeds treated with medication with humidifying water (10-15 l/t) was carried out at the beginning of the third decade of May batch drill. Predecessor – fallow. Sort of wheat is Karabalyk 92, barley – early Karabalyk. Seeding rate of 3.5 – 4 mln pcs/ha, depth – 4-5 cm. The size of the plots – 10 m2, repetition – quadruple. Basic surveys and observations made in the experiments: – The energy of germination, seed germination and musty (analysis of 100 seeds in four repetitions); – Phenological observations during the growing season; – Defeat seedling root rot in the 2-3 leaf stage (50 plants in 4 fold repetition);
– Affecter ears of corn smut in the flowering stage (analysis of 200-250 ears for each repetition); – Consideration of the harvest, the analysis of its structure and biometric indicators of plants (50-100 pcs. for each option). There were drier with significant insufficient precipitation, but it was not reflected to receive good sprouts. The summer months were generally favorable to the growth and development of crops and manifestations of disease with a sheet-hypophyseal infection. In June or during sprouting – tillering plants dropped more than 120 mm of rain or 2.5 – 3 times the long-term norm. The average daily air temperature was closer to the long-term. July was characterized by significant shortfalls in precipitation and higher average temperature. However, soil moisture was sufficient, in the second decade of the month 10-11 am on crops remained plentiful dew. The first decade of August was also damp, 39.5 mm of rain or more fell that 2 times as much long-term average, the average temperature was lower by 1.5 °C, which delayed the ripening of grain crops (Table 17). Laboratory screening. To determine the growth-stimulating activity of the PMF at different dilutions of the parent drug, a series of laboratory experiments were carried out. It was stated that it exhibits a specific physiological activity. Low temperatures (12-17 °C) significantly accelerates the formation of the second leaf spring wheat.

On the accumulation of leaves-hypophyseal mass exceed prototype version control from 11.5 to 47.2%, and the weight of the root system – from 8.2 to 27.9%, and barley – from 7.4 to 16 20,5 125
and from 4 to 39.7% respectively. The most growth -stimulating activity of the drug was shown at dilutions of 1:10 to 1:50, and at 1: 100 it declined. Prevalence of barley root rot in the experimental variants was lower 1.7-1.8 times. This indicates that the drug may be inducers of plant resistance to disease (Table 18).

On the basis of laboratory research the optimum concentration or dilution of PMF has been verified, which stimulates the growth and development of seedlings. Taking into account that in seed dressing chemicals crops for their hydration it is recommended to take water at the rate of 10 liters per 1 ton of seeds, field trials were established at a rate of preparation 0.4 and 0.2 liters per 1 ton of seeds that correspond to its PMF dilutions 1:25 and 1:50. The results of surveys and measurements are shown in Tables 3-5. Accounting for laboratory and field germination of spring wheat showed that in the control variant it is very high (97.3%) and under the influence of PMF there is no noticeable change in its figure. Germination of seeds was increased by treatment with chemicals which significantly reduced prevalence of plant root rot (Table 19). In phase two heading replicate plots planted with seeds treated with PMF, this drug was sprayed at the rate of 0.250 liters per 1 ha. Determination of wet weight of ears during breast ripeness showed that its index is much higher in the plots where seeds and crops during the heading stage were treated with a new drug. If selective harvesting combine found that a significant increase obtained by pre126
sowing treatment of phytomicrofertilizer at a rate of 0.2 l/t – 3.4 and 0.4 l/t – 7.3c/ha. Further spraying their crops during the heading level of allowances does not exceed 4.8 kg/ha. Analysis of the structure of the crop and biometric indicators revealed that it was obtained by the stimulating effect of the drug on the growth of plants, the formation of the reproductive organs, resulting in increased grains of ear and weight of 1000 grains. In many respects the structure of the crop option of treating seeds and crops during the growing season clearly excelled over the control (Table 20 and 21). It is advisable to continue research to clarify the effectiveness of phytomicrofertilizer on cereals depending on weather conditions, terms and methods of application. To improve competitiveness and reduce the cost of seed treatment is necessary to determine the physiological activity of the drug in a dilution of 1: 100, 1: 250 and 1: 500 which meet the standards of its rate of 100, 25 and 12 of drug per 1 ton of seeds.

The experience laid on barley showed that phytomicrofertilizer slightly reduces the germination of seeds, although its laboratory component was high – 98.6%. Chemical drug kinto-duo effectively suppressed the development of molds and reduced the prevalence of 127
plant root rot 1.6 times. Number of affected loose smut ears in the control variant does not exceed 1.3%, the disease is not detected in the processing of seeds with kinto-duo, PMF has reduced prevalence of the disease in the plants 2 times. When barley seed were treated with kinto-duo, an additional yield of 3.3 c/ha was produced in case of phytomicrofertilizer – 5.7 c/ha. However, the processing of the crops was not gain, although this method has a positive influence on the formation of grain yield and weight.

Phytomicrofertilizer significantly stimulated the initial growth of spring wheat and barley. In the treatment of wheat seeds of the drug dilutions from 1:10 to 1: 100, prototype options exceeded the retention sheet for hypophyseal mass from 11.5 to 47.2% of the root system – from 8.2 to 27.9%, and on barley – from 7.4 to 20.5 and from 16.4 to 39.7%, respectively. Higher stimulating effect of the drug was observed at dilutions 1:25 and 1:50. At low temperatures (12-17 °C) phytomicrofertilizer significantly accelerates the growth of spring wheat, which indicates the increase in the resistance of plants to abiotic stress. In field experiments the stimulating effect of phytomicrofertilizer was confirmed on the growth and development of wheat and barley. As a result, stimulation of vegetative growth of plants and the formation of the reproductive organs, increasing grains of ear and weight of 1000 grains in the processing of their seeds the obtained yield of spring wheat increased from 3.4 to 7.7 c/ha with the average yield in the control of 40.2 c/ ha, and on barley – from 3.9 to 5.7 c/ha. It reduced the prevalence of ears of barley loose smut 2 times. On the basis of laboratory and field experiments there was determined the best optimal consumption rate or concentration of the drug to stimulate the growth and development of crops. The obtained data allow applying for an innovative patent to use the drug to increase grain yields and its resistance to biotic and abiotic stresses.
Conclusion 1. The Material Safety Data Sheet approved by the Committee of Industry, Ministry of Industry and New Technologies of the Republic of Kazakhstan dated 16 June 2014 RK-Chemical production number №0000288 was obtained. 2. It is stated that fusicoccin significantly stimulates initial growth of spring wheat and barley. On the accumulation of leaves, shoots hypophyseal mass culture experienced the first variants exceeded the control from 11.5 to 47.2%, the root system – from 8.2 to 27.9%, and barley – from 7.4 to 20.5 and from 16.4 to 39.7%, respectively. Higher stimulating effect of the drug was observed at dilutions 1:25 and 1:50. At low temperatures (12-17 °C) fusicoccin accelerates the growth of spring wheat, which indicates the increase 130
in the resistance of plants to abiotic stress. In field experiments, as a result of stimulation of the vegetative growth of plants and the formation of the reproductive organs, increasing crop spike and 1000 grains weight of seed treatment of spring wheat, the yield increase was from 3.4 to 7.7 t / ha with the average yield in the control of 40.2 t / ha and on barley – from 3.9 to 5.7 t/ ha.
