The resistance to strawberry Verticillium wilt caused by Verticillium dahliae was studied after the symbiosis between strawberry and Glomus mosseae and Glomus versiforme. The results showed both the G.mosseae and G.versiforme have obvious control resistance to strawberry Verticillium wilt. Comparing with the control, the disease index(DI) of the treatment inoculated with G.mosseae and of the treatment with G.versiforme were reduced by 39.4 and 34.7 respectively, the control effection is 66.22% and 58.32% respectively. In addition, the two VAM fungi showed obvious effection of promoting growth. The plant height, diameter of stem, length of root, fresh weight of shoot of both treatments inoculated with G.mosseae and G.versiforme were significantly higher than that of the control.
