Abstract

The invention discloses a method for measuring pathogenicity of pathogen wood-rotting fungi in basidiomycetes by standing timber stems. The method includes the steps: (1) manufacturing a wood dust culture medium containing 82% of wood dust, 15% of wheat bran, 2% of glucose and 1% of gypsum; (2) introducing bacterial strains into the wood dust culture medium and manufacturing an inoculant stick; (3) selecting a young tree, disinfecting the young tree, cutting a stem 10-30cm away from the ground to form a 1-5cm long and 1-5mm deep notch serving as an inoculation position matched with a shear mouth on one side of the inoculant stick, attaching wet cotton to the lower end of the inoculation position to preserve moisture, fixedly wrapping the inoculation position with a plastic strip, and wrapping the stem about 5-10cm away from the upper portion of the inoculation position with thick paper to form an umbrella to cover the inoculant stick; (4) performing inoculation and infection for 1-2 months, unfastening the thick paper and the plastic strip wrapping an inoculant and verifying the pathogenicity. By the method, the young standing timber stems are inoculated for the first time, the pathogenicity of the pathogen wood-rotting fungi causing tree stem rot and root rot is measured, success rate is high, and operation is simple.

Description

technical field [0001] The invention relates to the field of plant protection, in particular to a method for inoculating pathogenic wood rot fungi in basidiomycetes by using the stems of living standing trees and its pathogenicity verification application. Background technique [0002] Wood-decaying fungi can degrade rotten wood and fallen wood, most of which are Basidiomycota fungi, some of which can infect the stem or root system of standing trees in forests, causing stem rot or root rot of trees , affect the growth of trees, and in severe cases, the whole plant will die. It is an important pathogenic wood rot fungus. For tree stem rot or root rot caused by pathogenic wood-rotting fungi, the determination of pathogenicity is a big problem in the process of completing Koch's law to verify its pathogenicity. At present, most of them use artificial inoculation of isolated materials to complete the determination of the pathogenicity of tree stem rot or root rot caused by wood...
