Drought Resistance of Pinus massoniana Seedlings Inoculated with Ectomycorrhizal Fungi
In order to explore the role of protective enzymes in raising the drought resistance of Pinus massoniana seedlings inoculated with ectomycorrhizal fungi, two mycorrhizal fungi were tested, and the activities of protective enzymes in the needles of the inoculated seedlings were determined under drought stress. The results indicated that the seedlings inoculated with Lactarius insulsus had the highest drought resistance, next came the seedlings inoculated with Laccaria aemthystea, and the seedlings without mycorrhizal fungi inoculation, namely the control of the experiment had the lowest drought resistance. It was found that inoculating the seedlings with L. insulsus, the content of MDA and the activity of SOD increased slightly, whereas the activity of POD and cell membrane permeability changed significantly, and positively correlated with the drought resistance of the seedlings. It was concluded that the cell membrane protective enzyme playing an important role in drought resistance improvement in Pinus massoniana seedlings inoculated with ectomycorrhizal fungi.
