Recently, the climate has become increasingly unstable, it leads to an imbalance of natural systems. Temperature anomalies and droughts cause stress in plants. Therefore, the using of growth regulators that increase the resistance of plants to adverse environmental factors has a promising direction. The purpose of the research was to study the influence of the phytohormone epibrassinolide on yield and lipid peroxidation (LPO) of pea plants. Pea plants were grown in the field, one group of plants was treated with phytohormones at the seed stage, the other – at the crop stage. For seed treatment epibrassinolide was used at a concentration of 10-8M, for crop treatment – at a concentration of 10-9 M. Control plants were treated with an appropriate amount of water. The content of diene conjugates Schiff bases and biological yield were measured and the membrane stability index was calculated. Researched phytohormone increased the biological yield of peas both during seed and crop treatment. The treatment of pea seeds with epibrassinolide did not affect the content of LPO products, however for crop treatment epibrassinolide increased the content of Schiff bases. Membrane stability index decreased by 1% during crop treatment. Epibrassinolide can be used to increase the yield of pea plants and pre-sowing seed treatment is more expedient.
