Young plants of Shatian pomelo shaddock are inoculated with arbuscular mycorrhizal fungi during transplantation. From the commencement of the experiment, the condition of the arbuscular mycorrhizal fungi in the root-system, the comparative water content of the leaf blade, the parameters of the photosynthesis, the content of the chlorophyll, ABA, praline and the N, P, K content of stem and roots are sampled periodically. The results show that the course of AM fungi infection is very fast and inoculating arbuscular mycorrhizal fungi to young plants increases the concentration of chlorophyll, strengthens the whole output of photosynthesis and raises the transpiration rate of leaf and stomatal conductance. Meanwhile it decreases the ABA content of leaf, and also abates the level of plant water pressure. What is more, it can absorb the water effectively, enhance the comparative water content, promote the growth of seedlings and improve ability of seedling to resist draught. In the mean time, inoculating arbuscular mycorrhizal fungi to young plants will facilitate the accumulation of N, P(especially improve the content of P), speed up the growth of young plants, increase live weight of seedling, especially on stem. In addition, arbuscular mycorrhizal fungi inoculation method is simple. It can obviously help Shatian pomelo through the drought period and improve the economic benefits, This approach can be used in a large area in Chongqing city.
