Abstract
The test studies on growth and verticillium wilt of cotton inoculated by AM fungi of Glomus mosseae and Glomus etunicatum,and discusses the possible mechanisms for induced disease resistance by AMF.The results indicate that the AMF inoculation can promote the growth of cotton plants and increase the content of chlorophyll in leaves.Under the condition of the combination of inoculation with AMF first and pathogen afterwards,the content of total phenol in cotton roots was increased,inducing the synthesis of POD enzyme in cotton roots was induced and POD activity was increased.The disease incidence and disease index of mycorrhizal cotton plants also decreased significantly.On the other hand,the mycorrhizal infection rate of cotton plants decreased when the plants exposed to pathogen fungi.It is proved that there are certain interactions between the two kinds of fungi,AMF and Verticillium dahliae.The establishment of arbuscular mycorrhiza symbiotic relationship between AMF and plant introduced influences on plant in many aspects,and the mechanism for the resistance of plant against pathogen induced by AMF is a complicated process involving many changes in plant tissue structure,physiology and biochemistry,such as improving plant nutritional status,competing photosynthesis products and colonization sites with pathogen,and activating plant defence reaction.
