The purpose of this work is to study the formation of adaptive reactions of grapes to the action of stressors of the winter period, by physiological and biochemical parameters, to identify varieties that have increased adaptive abilities for use in breeding. Objects of research are grape varieties of different origins: Kristall (control), Dostoynyi, Krasnostop AZOS, Vostorg, Aligote, Zarif. It was revealed that the increased resistance to winter stress conditions in the varieties Kristall, Dostoyny is achieved by a decrease in the water content of the buds by 9.09-10.40 %. In the varieties Vostorg, Dostoyny, Krasnostop AZOS adaptive resistance is achieved by increasing the starch content in the tissues of the shoots by 2.81-5.50 times in the pre-winter period. In varieties Krasnostop AZOS, Vostorg an important contribution to the formation of adaptive processes was made by water-soluble sugars, the content of which increased 2.82 and 2.89 times as a result of starch hydrolysis. An increase in the activity of peroxidase (2.49-2.75 times) indicated the instability of varieties Zarif, Aligote. Varieties Vostorg, Dostoynyi, Krasnostop AZOS have increased adaptive abilities in comparison with other studied varieties and are recommended for use in the breeding process.
