Variability of biochemical indicators and adaptation of F. (var.) erythranthera sanio and F. (var.) sulfuranthera kozubow forms of the pine (Pinus sylvestris L.) in the conditions of excess humidification

Dynamics of maintenance the photosynthetic pigments (chlorophyll and carotinoids), free proline, stressful proteins, ascorbic acid and activity of peroxidases in needles of the pine forms ( Pinus sylvestris ) differing with color of microstrobil in the conditions of continuous excess humidification of soils in the lower reach of Northern Dvina river is studied. Levels of individual variability of these indicators during the different calendar periods are determined. The essential distinctions in seasonal dynamics of biochemical indicators testifying to bigger sensitivity and needs in development the protective functions of f. (var.) erythranthera Sanio in comparison with f. (var.) sulfuranthera Kozubow are revealed.
