PHYSIOLOGICAL AND BIOCHEMICAL STUDIES OF THE FROST-RESISTANT OF INTERSPECIFIC HYBRIDS OF GRAPES IN AUTUMN-WINTER PERIOD
The results of physiological and biochemical studies frost-resistant of grape varieties are presented in the article in natural and simulated environments. Ranges of variation of the Optima biochemical parameter of frost resistance (in the state of deep and compelled rest), allowed grape varieties such as Crystal, Krasnostop, AZOS, Dostoyniy to survive in extreme winter conditions of Anapa-Taman region, are established in result of study of stress factors influence of winter period on biochemical composition of plant organs of highly resistant to low temperatures grape varieties.
