| Sumario: | In conditions of increasing differences in the hydrothermal regime of the environment, all known adaptation mechanisms should be used fully, as at the level of individual varieties and at agrobiocenosis in general. The modern gardener needs high-productive, adapted to the growing conditions varieties of the Fragária × ananássa Durh. The resistant varieties of the Fragária × ananássa Durh. to negative environmental conditions is a basic characteristic, which shows an economic value and the effectiveness of their cultivation in an actual zone. The main physiological and biochemical indicators of resistance during autumn hardening and after temperature stress in winter are changes in the antioxidant system, interruptions of the protein-carbohydrate complex, accumulation products of membran’s lipoperoxidation, and changes in the fractional composition of water in leaves. The Fragária × ananássa Durh. production process is characterized by the following physiological parameters: pigment analysis, photochemical activity of isolated chloroplasts, respiration, and net photosynthesis productivity. Studies of physiological and biochemical resources of resistance to abiotic stress factors and productivity of Fragária × ananássa Durh. are shown. As a result of the carried studies, perspective variety of the Fragária × ananássa Durh. (“Tzaritza”) was identified for the creation of resistance berries’ agrobiocenosis. |
