| Summary: | Abstract The article studies the accumulation of photosynthetic pigments and the ratio of their forms in the needles of Juniperus communis L. in the mountainous middle taiga dark coniferous forests of the Southern Urals during the winter and summer periods in contrasting conditions of the tundra-clear forest transition zone within the same slope of Dalniy Taganay. The assessment of the morphophysiological state makes it possible to assess the adaptive capabilities of plants, which consist in changing the content and ratio of pigment forms, transformation of the life form, while the accumulation of the pigment composition does not depend on age. Adaptation of the photosynthetic apparatus at the level of the ratio of photosynthetic organs allows this species to maintain growth parameters and gain an advantage in light spruce forest conditions. |
