The Mechanism Research of Host Resistance Enhanced by the Composite Mycorrhizal Fungi under Water Stress

Abstract:

The mechanism of resistance enhanced by composite endomycorrhizal and ectomycorrhizal fertilizers under stresses had been studied. The results showed that under water stress, the seedling height, ground diameter, aboveground and underground dry weight, relative water content, WUEof WS+F treatment group were higher than that of WS+NF treatment group, to which were respectively higher 55.09%, 59.22%, 29.98%, 75%, 26.49%、142.86%. The RWD, Pro and MDA content of the inoculation of composite mycorrhizal fungi treatment under the stresses were all significantly decreased. In the aspect of antioxidant enzymes activity, SOD, CAT and POD activity of WS+F treatment group increased than that of WS+NF treatment group to 13.45%、59.88%、45.58%. Because of the series responses of Chinese fir seedling inoculated with the composite mycorrhizal fungi, which were benefit for promoting growth, improving water use efficiency, improving the physicochemical character of soil, etc, the resistance of plant had been improved to stress.
