The effect of xylotrophic basidiomycetes on the photosynthetic pigments of small-leaved trees

Xylotrophic basidiomycetes are an essential component of any biogeocoenosis. It is due to these organisms that one the most important processes occurs throughout biosphere, namely decomposition organic substances and, first all, cellulose, which synthesized by producers. However, phytopathogens bring significant losses forestry, making wood unsuitable for industrial use. At same time, sufficiently effective methods diagnosing and assessing damage heartwood rot, caused xylotrophic basidiomycetes, have not been developed. The paper studies peculiarity influence on pigment apparatus valuable small-leaved tree species using spectroscopy electrophotocolorimetry, while comparing rate degradation main pigments photosynthesis chlorophylls a b pheophytin, as well assesses content chlorophyll, auxiliary such carotenoids xanthophylls in healthy trees with signs pathogenic xylotrophs. A number effects leaf identified. Among those rapid primary secondary pigments, distortion chlorophyll concentration data filter properties photoelectric colorimeter higher affected comparison control sample. These results obtained can be actively used both forestry assess phytosanitary state trees, further study features interaction woody plants.
