Abstract: To study the arbuscular mycorrhiza inoculation on growth and drought resistance of maize (Zea mays) in soils with high phosphorus availability, a pot experiments was carried out by the inoculation of Glomus intraradices and Glomus etunicatum. There were three irrigation levels, 70%, 45% and 20% of soil field capacity. The results show that compare to the non-mycorrhizal treatment, the mycorrhizal inoculation increases the host plant shoot and the phosphorus contents of shoots and roots significantly. Hydraulic potential, the contents of prolin, POD and CAT of maize leaves are decreased under the treatments with 45% and 20% of soil field capacity. The mycorrhizal inoculation increases the hydraulic potential, POD and CAT activities and decreases prolin concentration of host plants which relieve membrane lipid peroxidation caused by water stress. It can conclude that arbuscular mycorrhiza fungus could form symbiosis with host plants and improve drought resisting ability even under high soil phosphorus availability.
