Comprehensive analysis of physiological data of taxation phytomass of Pinus sylvestris (Pinopsida: Pinaceae) at the organism level in ontogeny European Russia

Was performed the comprehensive physiological analysis of forest taxation data phytomass of pine ( Pinus sylvestris L.) in the European part of Russia. Were obtained quantitative data net photosynthetic efficiency, carbon sequestration, the absorptive activity of the root system and the biological productivity of plants in the ontogeny of the ages of 10-30 to 130-220 years. Shown the specificity of the reaction to the pine contrasting climatic and site conditions in the vast expanses of the East European plain. Were identified the zones where the plants have a higher physiological characteristics and biological productivity. In all regions, with the age of the plants there was a decrease absorptive activity of the root system, the net photosynthetic productivity, carbon sequestration and biological productivity. Installed nonspecific adaptive response of plants to a progressive age-lack of nutrients, expressed in a change of attitude to the photosynthetic potential of the root in favor of roots. Such reactions allow the plant to increase the supply of mineral elements in the aerial parts to maintain vital processes of photosynthesis and possible stabilization of biological productivity in older age ontogeny.
