Pigment complex of natural flora plants of the European North-East

The content and ratio of photosynthetic pigments in leaves of 120 species, growing in the SubPolar Ural Mountains, the South Tyman, in the middle stream river-basin of Vychegda, was investigated. The significant differentiation of species on the green and yellow content was revealed. At advancement to the North the increasing of the relative content of carotenoids in a row boreal - hypoarctic - arctalpine species was revealed. As a whole, these results extend our knowledge about mechanisms of adaptation of pigment apparatus and photosynthetic function realization in plants under cold climate environments.
