The effects of inoculating arbuscular mycorrhizae fungi (AMF) on the growth and verticillium wilt of eggplant were studied, with the possible mechanisms for induced disease resistance by AMF discussed. The results indicated that the AMF inoculation promoted the growth of eggplant plants. The disease incidence and disease severity index of eggplant plants inoculated by AMF were decreased significantly. In the combination of inoculation with AMF first and pathogen afterwards, the proline content and the relative electrical conductivity in eggplant leaf were lower, the root activity was higher, and POD, PPO and PAL activities were higher than those of inoculating pathogen alone. Our experiment confirmed that AMF had certain biocontrol effect on eggplant verticillium wilt. The resistance of plant against pathogen induced by AMF possibly resulted from improving plant nutritional status, thus activating the mechanism of plant disease resistance.
