Study of the influence of stevia glycoside compounds on antioxidant activity of agricultural plants

Currently, there is a need to create environmentally friendly bioregulators of plant growth. Stevia Stevia rebudiana Bertoni is known to be a promising source of substances with an antioxidant effect. It has been established that stevia contains diterpene glycosides with growth-regulating activity. Studies have been conducted to study the antioxidant activity of diterpene clicoside extracts at concentrations of 10-4%, 10-6%. 10-8%. It was found that in wheat seedlings treated with diterpenoid extracts, the level of ascorbate oxidase and peroxidase increases, which is a consequence of reducing the oxidative stress of the plant, the value of peroxidase indicators decreases. The level of little-new dialdehyde as an important indicator of cell oxidation decreased by 10-8% when treated with glycoside extract, which indicates its protective effect on the oxidative status of plant cells. It was revealed that when exposed to diterpenoid extract in a concentration of 10-8%, optimal indicators of laboratory germination and germination energy were observed. Extracts of diterpene glycosides are promising components for creating products with growth-stimulating and antioxidant effects.
