CHANGES IN THE CHEMICAL COMPOSITION OF WOOD PECEA OBOVATA LEDEB. UNDER THE INFLUENCE OF IPS TYPOGRAPHUS L.
UDC 630*85,5(045)
Abstract
The process of forest destruction is very dynamic and covers the entire boreal zone of the Northern hemisphere. Against the background of deterioration of the sanitary condition of plantings, pathogenic organisms become more active. The article presents materials on the study of the chemical composition of wood of individuals of various life conditions of Siberian spruce (Pícea obovata Ledeb.) in the conditions of distribution of bark beetle (Ips typographus L.). Plants of various life States were studied for the content of water-soluble and resin-like extractives, tannins, lignin, and polysaccharides. The obtained data were subjected to statistical processing. Under the influence of the bark beetle-typographer, no significant differences were found between individuals of different life States in the polymer structural components of spruce wood (lignin and polysaccharides). In the course of the study, it was noted that during the colonization of bark beetles in plants, the content of extractive substances increases. With deterioration, the proportion of phenolic compounds begins to increase from 25.8% in plants of good condition to 37.5% in plants of unsatisfactory condition, with a decrease in the proportion of resinous substances. An increase in phenolic compounds is associated with an increase in tannins. The highest content of all groups of metabolites (including tannins) was observed in individuals of a satisfactory life state and is 7.15% of the a.s.s.
