Аннотация: The rate of accumulation and location of proanthocyanidins and lignin was studied in fir (Abies sibirica Ledeb.) trunk phloem inoculated with two species of pathogenic micromycetes Verticillium sp. and Thysanophora sp., the usual associates of the sawyer Monochamus urussovi Fisch. Greater accumulation of the phenolic substances and more rapid localization of pathogen as a result of a hypersensitivity reaction were detected in firs infected with Verticillium sp. It was concluded that accumulation of proanthocyanidins and lignin is a part of nonspecific immune response of fir to the pathogen action and that the pathogen specific of fir can inhibit induced synthesis of defensive substances by the host plant.
