Eight excellent individuals were preliminarily selected for further identification of cold resistance and high yield. They selected single plants were 57-1, 57-3 and 55-24 of combination 6- 34-1×S1-5, 56-3, 56-5 and 55-19 of combination 6-34-1×S3-1, 21-12 of combination 6-37-2×S3-1 and 21-12 of combination 6-23-1×S3-1.展开更多

Kuntze) and hazelnut (Corylus pontica C. Koch.). The indicators, which not only describe the physiological state of plants in the stressful period, but also allow it to identify more adaptive varieties within a given area was determined. Analysis of catalase activity data in Chinese tea and hazelnut revealed the presence of similar patterns: there is a change in enzymatic activity in response to hydrothermal factors. It is established that the stable varieties Camellia sinensis (L.) O. Kuntze and Corylus pontica C. Koch. characterized by a more active catalase, which is of particular importance during droughts. The water regime parameters variance scale for Camellia sinensis was developed, which allows differentiating varieties into groups of varying degrees of stability. It is shown that all methods that are used to estimate stability of plant species to extreme environmental conditions are based on several basic principles connected with peculiarities of adaptation mechanisms. The result was a selection of diagnostic indicators proposed for assessing adaptability: the water content of the leaf tissue, water-holding capacity of leaves, and concentration of cellular juice sprouts and activity of catalase.展开更多
