Abstract： In this paper, the mycorrhizal infection rates of Bretschneidera sinensis under different water treatments (40%, 60%, 80%, 100%) and time points were determined. Quantified morphology characteristics of the seedlings such as heights, ground diameter, and number of leaves, together with malonaldehyde content and survival rate in the inoculation group and the control group before and after different water treatments were also determined. The results showed that, under the condition of relative soil moisture content of 60%, the infection rates of mycelium, arbuscula and the total were the highest, low moisture content (40%) and high moisture content (≥80%) were not conducive to mycorrhizal fungi on the seedlings infestation; the content of malondialdehyde in the inoculated seedlings was significantly lower than that of the control at 40% and 60% treatments, suggested that inoculation with Funneliformis mosseae could increase seedling resistance to drought stress, but with no obvious effect on treatments of 80% and 100% high moisture content; the relative water content of soil suitable for seedling growth under natural and inoculated conditions was 80% and 60%, respectively; under the same water conditions, the survival rate of inoculated seedlings was higher than that of the control, with the highest (90%) under 60% treatment, while the survival rate of seedlings was relatively low at 40% low moisture content and 100% saturated moisture content
