Through potted inoculation experiment, grape cutting seedlings of six cultivars with different growthpotential were selected as plant material to explore the effect of Glomus mosseae（Gm） on arbuscular mycorrhizalfungus（AMF） infection rate and hyphal enzyme activity, and to analyze the effect of AMF on inorganic nutrient ab-sorption capacity of the materials. The results showed that Gm vaccination could significantly improve AMF coloni-zation of tested cultivars and infection rates of strong growth potential cultivars were significantly higher than theweak growth potential cultivars. Inoculation improved hyphal enzymes（ALP and SDH） activity of tested material infollowing order: Meiguimi ＞ Zaoheimi ＞ Shuijing ＞ Weilasha ＞ Jingxiu ＞ Red globe. Inorganic nutrients absorptionof tested grape cultivars were affected by the formation of AM, and absorption of major elements increased morethan trace elements. Content of major elements in root, stem, leaf were significantly higher than CK, whereas traceelements in parts of the tested materials were lower than CK, especially in stem. Contribution rate of Gm to the ab-sorption of inorganic nutrients behaved differently in different cultivars, contribution rate to relatively weak growthpotential cultivars were higher than the stronger growth potential cultivars.
