Modeling the Effect of Nanopolymer Preparations on the Contents of Micro and Macroelements in Soybean Seeds and Рlants

Abstract

Conducted research to study the influence of nanomaterials on seeds, plants and resulting products, on metabolic processes in plants is one of the pressing problems. The purpose of the study was to study the effect of nanopolymer preparations on the concentrations of micro and macroelements in seeds and plants. In all experimental variants studied, in thirty-day-old soybean plants, the copper concentration decreased significantly compared to seeds. Thus, in the seeds of the soybean variety Baraka treated with the preparation PMC Cu2 +:Ag 8:2, the concentration of copper decreased in thirty-day-old plants by almost 1.5 times compared to the seeds. The concentration of iron in thirty-day-old plants also decreased compared to seeds treated with nano and polymer preparations. Our studies revealed that nanopolymer preparations Nanoascorbate chitosan 0.5% (4:1), PMC Cu 2+ :Ag 7:3, PMC Cu 2+ :Ag 8:2 have high biological activity, the content of micro and macroelements in plants whose seeds treated with nanopolymer preparations contributed to a more uniform distribution of the concentration of these elements in all phases of soybean plant development than polymer ones. The nanopreparation PMC Cu 2 + :Ag 7:3 acts on the substrate-enzyme complex of plants and enhances biochemical reactions due to copper, which has a small ionic radius and many orbitals of different symmetries (S, P, d), allowing one to get very close to the enzyme co-factor. The simulation results show that the closer the two parabolas (I and II) are, the greater the Franco-Condon Factor will be, which increases the probabilities of biochemical reactions.
