| For the first time for different ecological conditions of the Volga region, quantitative data have been obtained on the net photosynthetic productivity, biological and mineral productivity of Scotch pine plantations at the individual tree level in ontogenesis. It is shown that a non-specific adaptive reaction of plants to the growing nutritional deficits with aging is manifested in increasing the ratio of the root system/photosynthetic potentials. |
