摘要：The effectiveness of Glomus mosseae and Glomus fasciculatum to control Verticillium wilt on cucumber was assessed under greenhouse conditions. Several parameters were considered to assess the disease reduction by the arbuscular mycorrhizal fungi (AMF) included shoot and root biomass, disease severity and nutrient contents (N, P and K). After 10 weeks from planting the height of cucumber plants inoculated with G.fasciculatum was significantly (138.5 cm) different compared to all other treatments, but the combined treatments (G. mosseae & Verticillium, G. fasciculatum & Verticillium) were similar to control plants (117.5cm, 122.5cm, 121cm respectively). Leaves number were in G.mosseae treatment not significantly different compared with the combined inoculation of G. mosseae and Verticillium. Cucumber shoot and root biomass were significantly increased in G. fasciculatum treatments compared with G. fasciculatum & V. dahliae treatment. Disease severity was decreased significantly in the combined treatments of G. mosseae and Verticillium, G. fasciculatum and Verticillium (2.5, 3.2 respectively) as compared to V. dahliae infected plants (6.5). The current study illustrated that shoot and root nutrient analysis of N, P and K were increased in the combined treatments and AMF inoculated plants as compared to infected plants. Roots colonized by both species of mycorrhizal fungi were higher compared to combined treatments of the AMF and Verticillium. Mycorrhizal spore production was higher in plants inoculated with G. mosseae compared with the other treatments. G. fasciculatum & V. dahliae and G. mosseae & V. dahliae treated plants were more significantly tolerant to disease infection compared with Verticillium infected plants.
