Contemporary issues of ecological plant physiology and solutions (the case study natural flora of boreal zone)

The modern direction, methods and approaches ecophysiology of plants are given. The results of the study of respiratory and photosynthetic activity of plants boreal European North-East are described. Showing the variation limits of these parameters depending on the species diversity of life forms and geographic group. We give mathematic models describing the relationship of photosynthesis and respiration rates of the nitrogen content of leaves.
