【Objective】 The growth and the impact of drought tolerance of Cabernet Sauvignon after inoculating AM(Arbuscular mycorrhizal) fungi was studied in this experiment in order to provide theoretical basis for promoting the ues of AM fungi in production.【Method】 Cutting seedlings were inoculated by Glomus mosseae(Gm),Glomus etunicatum(Ge) and the mixture of Ge and Gm in the pot and the control were treated by the same AM inoculants after disinfecting through high-temperature.The mycorrhizal colonization rate and the grape's growth were determinated after 100 d,then drought resistance of different cutting seedlings were compared with each other after drought stress for 30 d.【Result】 AM fungi inoculation significantly enhanced the growth of Cabernet sauvignon,and Mycorrhizal dependency was correlated with the mycorrhizal colonization significantly.The activity of three protective enzymes,SOD,CAT and POD of Cabernet Sauvignon leaves,increased significantly,MDA content and relative conductivity decreased,and the drought tolerance of Cabernet Sauvignon was remarkably improved during drought stress.【Conclusion】 The effect order of three AM fungi inoculants was GmGeGm+Ge.The mixture of AM fungi inoculants was an effective quomodo for the ectomycorrhizal fungi utility.
