The aim of the study was to evaluate the ef-fect of salicylic acid on the processes of re-generation and root formation in vine grafts during the stratification period. The efficiency of treatment of copulation sections on root-stock cuttings of vines with Salicylic acid (SC) solution was studied) (10-2, 10-4, 10-6, 10-8) during the production of grafted grapevine seedlings. For setting up the experiment, we used the grafted grapevine variety Cabernet Sauvignon, the rootstock - Kober 5BB. In some variants of the experiment, a reduction in the period of vaccination stratification was noted, due to the activation of the process of wound tissue formation. At the same time, the use of salicylic acid stimulated the budding of the scion, the growth of shoots and the devel-opment of the root system. With an increase in the concentration of the solution to 10-2, a slowdown in the growth of shoots was noted. The present results indicate that salicylic acid, being an endogenous stimulator of growth processes, can be used in nursery production.
