The main aspect of the A.N. Bakh peroxide theory of slow oxidation is the development of con cepts on the role of peroxide compounds and the early stages of activation of molecular oxygen in reactions of biological oxidation. The use of modern physicochemical methods, namely, spectroscopy, pulse radiolysis, and ac polarography in studying the catalytic and antioxidant properties of natural compounds, flavonoids, makes it possible to detect the oxidation reaction intermediates which represent the partial charge transfer complexes [ ] and also to explain the possibility of formation of nanostructured metal particles in reverse micelles in the presence of oxygen with quercetin Qr acting as reducing agent.

The article presents studies on the impact of ultraviolet light-emitting diodes and silicon-containing preparation “Nanosilicon” on the germination of seeds of meadow clover ‘Ranny 2’, alfalfa (Medicago varia) ‘Victoria’ and fodder galega ‘Yaltinsky’. The purpose of the studies was to investigate the synergism of the simultaneous exposure to ultraviolet radiation and nanosilicon to increase the rate of seed germination. The study was investigating ultraviolet radiation zone “A” (UV-A) for a period of 5 minutes. The average irradiance was 3.137 W/m2. A decrease to 2-3% of the amount of hard seeds of meadow clover was noted in the variants: first treatment was with ultraviolet light, and then with “Nanosilicon” (UV irradiation + “Nanosilicon”) and vice versa: first, treatment was with “Nanosilicon”, and then with ultraviolet (“Nanosilicon” + UV irradiation). In addition, a decrease to 7.9-9.5% of the seeds contamination was detected for fodder galega in almost all studied variants. The use of the preparation “Nanosilicon” and UV radiation on the seeds of alfalfa contributed to an increase in the length of the sprout up to 2.4 cm, the root up to 1.5 cm, the degree of development of seedlings up to 3.0 points, the growth rate up to 29.8%.
