Abstract
With the purpose of forecast of changes in the biochemical composition of tissues and intensity of the production process of Siberian species of conifers under the influence of global climatic changes, morphogenetic characteristics of trees and the content of carbohydrates, proteins, free amino acids and nitrogen in storage tissues and of cellulose, lignin, and hemicelluloses in the wood of Scots pine, Siberian larch and Gmelin larch were studied in subzones of northern and southern taiga and in the forest-steppe zone of Middle Siberia. It is hypothesized that the global climate warming will lead to a decrease of xylogenesis intensity and forest productivity on the northern and southern borders of the forest zone.
