The purpose of this work is to study the grapes adaptive resistance to the summer stress factors by physiologo-biochemical parameters, to identify varieties adapted for cultivation in the Anapa-Taman region. The objects of research were following varieties: Krasnostop, Dostoynyi – euro-american origin; Vostorg – amur-american; Zarif – eastern-european; Aligote – western-european, Kristall– euro-amur-american. The grapes adaptive stability was achieved by maintaining a stable ratio of photosynthetic pigments in the leaves during the summer growing season, increasing the content of carotenoids, proline and abscisic acid. The lowest values of the chlorophyll/carotenoid ratio (2.47-2.69) were found in the Zarif variety, the maximum increase in the proline content (8.9 times larger) was observed in the Kristall variety. It is shown that the protective response induction is more expressed in the varieties Dostoynyi, Krasnostop, Crystal, and Vostorg and they proved to be more adaptive in comparison with the Aligote and Zarif varieties in the summer of 2020.
