The effect of selenite-ion on the reactions of lipid peroxidation, the electrolyte release, the membrane damage coefficient and the growth parameters of winter rye seedlings of the Tatiana variety under optimal water supply conditions and during a seven-day drought was studied. Seeds treatment with 5.8·10-3 M sodium selenite solution reduced the accumulation of lipid peroxidation products in the leaves - lipid fatty acid hydroperoxides and malondialdehyde under optimal and stressful conditions. To a greater extent, selenite-ion reduced the content of malondialdehyde compared to hydroperoxides (by 25%). The effect of selenium on lipid peroxidation reaction was more effective in drought conditions. The inhibition of electrolyte release from seedlings leaves enriched with selenium was revealed. The coefficient of membrane damage in drought conditions was lower in the variant with selenite-ion (by 37%). The large mass of aboveground seedling organs, length and weight of the root system when treating seeds with sodium selenite were noted. The obtained data are discussed in connection with the effect of selenium on the content of auxins, expressing genes responsible for the antioxidant enzymes synthesis.
