| Popis: | Modern agricultural production requires innovative technologies. For a labile technological process of grain growing the following things are necessary: precise (coordinate) farming, crops protection in the form of controlled coexistence with undesirable life forms and a single pre-treatment with biopreparations based on biogenic metal nanoparticles. Physical-chemical properties of nanoparticles contribute to biocompatibility and biological activity when interacting with wheat and other crops. The paper shows relationship between the size of metal nanoparticles and their effect on wheat seedlings at concentrations of 0.001-1.000 g/t. The activity of superoxide dismutase and catalase in the crops significantly decreased when maximum morpho-physiological parameters and increased sharply at concentrations above 100 g/t and 10 g/t, respectively, for nanoparticles sized 35-60 nm and up to 20 nm. For nanoparticles sized 35-60 nm the stability limit was the concentration of nanoparticles much higher than 100 g/t, and for those up to 20 nm it was 0.001-10 g/t. The content of hormone indole acetic acid increased under the action of nanoparticles, which increased energy efficiency of plant respiration, activity of enzymatic reactions and wheat yield and grain quality when strengthening the seedlings’ viability, reducing the effect of weeds to minimum. |
