Ecological-physiological characteristic of resource kind plants Aconitum septentrionale Koelle in communities of Sonth Timan and Subpolar Urals

Ecological-physiological characteristic of aconite plants (Aconitum septentrionale) in coenopopulations of Subpolar Urals (basin of headwaters of river Kozhim) and Sonth Тiman (river Soyva) is given. Microclimatic conditions in plants inhabitations are characterized. Dependence of photosynthesis processes and breath of plants on illuminance and temperatures is revealed. Distinctions in capacity and activity of the photosynthetic apparatus of plants growing in different ecological-coenotypical conditions are shown. Aconite is possible to carry to shade-enduring plants with expressed attributes of photophily that is shown in adaptation to dwelling in wood and poiums. Integrated effect of northern conditions reduces efficiency of light use on photochemical processes.
