The morphological parameters of apple (Malus) clonal rootstock 62-396 (infected and non-infected by ACLSV) on standard medium after one passage of its cultivation on nutrient media containing salicylic acid in different concentrations were studied in the conditions of the Republic of Belarus. It was established that cultivation of non-infected plants on media with salicylic acid caused significant reduce of average shoot length and propagation coefficient during subsequent passages. Addition of salicylic acid led to significant increase of microcutting vitrification rate. It was shown for regenerants infected by ACLSV that cultivation on media with salicylic acid resulted in increase of necrosis rate and callus formation during subsequent cultivation on standard nutrition medium. It was shown that salicylic acid addition to nutrient medium affected vital capacity of the studied rootstock regenerants; both infected and non-infected plants demonstrated this effect. We recommend using of 30 mg/1 of salicylic acid for chemotherapy.
