摘 要 ：以筛选自渭北旱塬葡萄园的3种土著AM真菌菌株Glomus mosseae（GM）、Glomus intraradices(GI)和Glomus versiforme(GV)为试材，在盆栽条件下研究了3种AM真菌单独接种及混合接种对酿酒葡萄赤霞珠（Cabernet Sauvignon）扦插苗营养生长指标的影响。结果表明，不同接种处理的葡萄幼苗AM 真菌侵染程度不同，混合接种显著高于单接种； 混合接种GI+GV＞GM+GV＞GM+GI，单接种GV>GI>GM。接种AM真菌促进葡萄幼苗的生长，显著提高植株高度和地上、地下干重，并提高葡萄叶片净光合速率、气孔导度、胞间二氧化碳浓度和蒸腾速率，从而提高葡萄叶片的光合作用； 葡萄叶片中叶绿素含量、可溶性糖含量、可溶性蛋白含量均高于未接种对照，且混合接种优于单接种。

Abstract:The growth promoting effects of three native AM fungi (Glomus mosseae, GM; Glomus intraradices, GI; Glomus versiforme, GV) which were isolated from vineyards in Weibei Tableland on Cabernet Sauvignon grapevines seedlings were investigated by using the controlled conditions with different inoculation treatments. Arbuscular mycorrhizae were found to form in the grapevine roots after inoculated with AMF, and there were differences of colonization among the different inoculation treatments. The results show that the mixed-fungi treatments have more mycorrhizal infection rates than those of the single fungus treatments. The mycorrhizal colonization caused by inoculum of GI+GV is of the largest efficient, followed by GM+GV, the least is GM+GI. When inoculated with single fungus, the mycorrhizal infection rate as follows: GV>GI>GM. At the same time, the plant height and dry weight are significantly increased. The inoculations of AM fungi can significantly increase Pn, Gs, Ci and Tr, and thereby enhance the photosynthesis of grape leaves, and the mixed-fungi inoculations have better effects than those of the single ones. Furthermore, the inoculations with AM fungi can significantly increase the contents of chlorophyll, soluble sugar and soluble protein of grape leaves.
