ABSTRACT: The
study of the water
status and activity of catalase in Chinese tea plants (Camellia sinensis (L.)
O. 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.
