The research results of the influence of silicon at the processes, taking place in plants indicate its crucial role. Its shortage increases the susceptibility of plants to fungal and bacterial disease etiology, reduce their productivity, drought, and frost and winter hardiness.
Laboratory monitoring of physiological processes in plants under the influence of mobile forms of silicon showed that increased activity of the plant processes of respiration, which is associated with increased activity of redox enzymes as cytochrome oxidase, polyphenol oxidase, catalase, ascorbic acid oxidase and peroxidase.
It is known that: polifenoloksidase is a single enzyme, which catalyzes the oxidation at low temperatures, the activity of this enzyme depends on the resistance of plants to high concentrations of chemical compounds; peroxide is contributing to their protective functions to disease; ascorbic acid provides resistance to drought; catalase activity is closely related to magnesium-porphyria and cytochrome oxidase has been actively involved in photosynthesis.
Thus, the obtained results indicate that there is a formation specific trigger of increasing plant resistance to stress factors under the influence of silicone compounds from the early stages of plant ontogenesis. The important role of silicon in the early stages of plant growth of wheat and maize is clearly visible in the photographs. Organic mineral mixtures Greenodin and soluble water glass differ in composition of silicon products, and control variant demonstrates the character of wheat seedlings and the formation of the root system of maize in the absence of mobile forms of silicon.
In the researches, the scientists used seeds of winter wheat variety of “Pereyaslavskaya” and maize varieties of “Favorite”. In the experimental variants the used dose of Greenodin White, Greenodin Black and SiArga 200-400mg per 200 g of sand or gray forest soil. Soil of gray forest podzolized with the following characteristics: the content of macro- and microelements, mg / l soil: N – 11,4; P – 305.2; K – 59.7; CA – 4331.6; Mg – 1524,1; Fe – 687,5; Mn – 95,5, pH – 4.8; humus content – 2.8%; content of microbial biomass – 265.6 g C/g soil; the content of phenolic compounds – 91.4 mg / kg of soil. Photos were taken between days 15-20 after seeding.
