Most of the experiments have indicatedthat Vesicular-Arbuscular Mycorrhizae were able to resist water stress ,improve water transportation and enhance ability of resisting drought stress. The paper summarizes that Vesicular-Arbuscular Mycorrhizae accelerate water absorption of host plant in the normal condition of water, advance growth of host plant, improve water metabolism, affect regulative matters and increase survival percentage of seedlings in the condition of water stress. Mechanism that Vesicular-Arbuscular Mycorrhizae can enhance resistance of drought stress in host plants may be many aspects.: (1) Mycorrhizae enlarge root areas of host plant; (2) Mycorrhizae stimulatehormoneto regulate metabolism ; (3)Mycorrhizae enhance absorption of mineral nutrition; (4)Mycorrhizal hyphae have special channels of water transported; (5) Mycorrhizae are due to mechanism of direct absorption of mycorrhizal hypha and indirect regulation of physiological function .
