Abstract

The effect of epibrassinolide in combination with salicylic acid and methyl jasmonate on the formation of complex resistance of clonally micropropagated potato plants of the Briz variety to the potato virus Y and to moisture lack, their physiological state, the functioning of the pro-/antioxidant system, as well as on the productivity and quality of the obtained mini-tubers was studied. It was revealed that antiviral resistance under combined stress conditions is formed only in the presence of epibrassinolide that triggers a series of protective mechanisms through accumulation of hydrogen peroxide, phenolic compounds and an increase in peroxidase activity, while maintaining productivity and improving the quality of the products obtained. The use of a three-component mixture is accompanied by the largest mass and a number of potato minitubers, while its protective effect against a viral infection is not manifested.
