In ad鄄 dition,the mycorrhizal treatments significantly increased the number of lst,2nd,and 3rd lateral roots. Inoculation with arbuscular mycorrhizal fungi significantly increased the root projected area, surface area,volume,and total root length (mainly 0-1 cm root length),but decreased the root average diameter. Meanwhile,G. versiforme showedthebesteffects. Mycorrhizalinoculat
