Ophiostomatoid micromycetes as indicators of the state of forest plantations in Middle Siberia

Abstract

The occurrence of ophiostomatoid fungi, associates of xylophagous insects, was established to be an indicator of the state of coniferous plantations under different anthropogenic influences and adverse eco logical conditions at the coenotic level. The sizes of necroses developed on a tree inoculated with blue stain fungus isolates were recorded to be indicators of the state of the tree at the physiological level.
