The results of physiological and biochemical studies frost-resistant of grape varieties are presented in the article in natu-ral 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 bio-chemical composition of plant organs of highly resistant to low temperatures grape varieties.
The results of hardiness evaluation of new apples varieties of different ripening to early and late winter frost, after thaw, under Kuban conditions are analyzed.
The stability of grapes types of different origin to the complex of the abiotic stress factors of summer period of Anapo-Taman zone is studied. On the basis of determination of anatomical-morphological and physiological and biochemical indexes it is established that the hybrids of Euro-American origin possess the combined stability to the stress factors of summer periods.
Laboratory and field data on studying of physiological and biochemical features of resistance to drought of different chromosomal apple-tree forms are presented.
Anatomical and morphological studies of generative buds of the apple tree variety maturing in autumn-winter period of development are conducted. Using light microscopy 3 groups of the generative buds, varying in degree of development of anthers are identified. The relation between the degree of the development of anthers and the winter hardiness of buds is revealed.
