| Abstract: | Avena fatua L. as a common weed in the farmland of Qinghai Province, was selected as the target receptor. The effects of Trichoderma polysporum HZ-31 on various physiological indexes of wild oats were determined after potted inoculation, and the physiological mechanism of the interaction between host and pathogen was analyzed. The results showed that there were various effects of Trichoderma polysporum HZ-31 on the defense enzymes of physiological mechanism of Avena fatua L., PAL and POD activity increased to resist the infection of the strain. The other physiological defense indexes including MDA content, CAT activity, PPO activity, SOD activity, soluble protein content and chlorophyll content were destroyed by the infection of the strain. The effect of the inhibited defense enzyme was greater than that of the promoted defense enzyme. The infection of HZ-31 inactivated or inhibited the main enzymes in Avena fatua L., interrupted the corresponding enzymatic reaction, and caused a wide range of metabolic changes in plants, including changes in cell membrane permeability, interference in photosynthesis, protein synthesis, phenol metabolism and other physiological changes. |
