Photosynthesis and productivity of plants aconitum Lycoctonum L. in mountain cenopopulations in territory of national park «Yugyd Vа»

Are resulted photosynthetic, productive and population characteristics of Aconitum lycoctonum, growing in forest mountain-tundra zones. In both cenopopulations plants showed properties of shade tolerance with moderately expressed signs of photophily and didn't differ essentially on leaves photosynthetic activity. In mountain-tundra cenopopulation plants of younger age condition prevailed, in forest - generative. Distinctions in habitus and efficiency of plants is limited more likely not by photosynthesis, but by growth processes. Probably that growth of plants in mountain-tundra zone is limited to the raised level of Uf-radiation.
