1)Mail' genera more than 90% - of VA mycorrhizal fungi may belong to the Glomus and Acaulospora according to the identification of spores collected from our university farm field due to the method of Schenck's manual, in which one species of Glomus sp. (etunicatum like)has a quite high ability to promote the growth and nutrient uptake of leguminous plants - cowpea. pigeonpea and groundnut - under the both conditions of relatively high and low fertilities of an An(losoil. The retardation of the defoliation and the promotion of ripening of these legumes due to VA mycorrhizal formation were clearly observed.2)The nodule activity in ripening stage of soybean maintained high level due to VA mycorrhizal formation by Gloms sp. (ettinicattim like)mentioned above in an Andosoil with enough level of phosphorus application resulted in also high protein content in grain.3)The contents of cytokinin, especially ribosylzeatin, in xylem sap and leaves at ripening stage of soybean infected with Glomus sp. (etunicatum like)were nearly double-fotir times higher than that without YA mycorrhizal infection.

（1）根据Schenck's manual方法对我校农田VA菌根真菌孢子的鉴定，90%以上的VA菌根真菌可能属于球囊霉属（Glomus）和无梗孢霉属（Acaulospora），其中球囊霉属（Glomus sp.）（etunicatum like）对豆科植物豇豆（Cowpea）的生长和养分吸收有很强的促进作用。木豆和花生-在相对高和低肥力的土壤条件下。VA菌根的形成明显抑制了大豆的落叶，促进了大豆的成熟。2）Gloms sp.（ettinicattim类）在施磷水平足够的安多土中也导致了籽粒蛋白质含量的增加。3）细胞分裂素，尤其是玉米素核糖基化，结果表明，接种Glomus sp.（etunicatum like）的大豆成熟期木质部汁液和叶片中的可溶性糖含量比未接种YA菌根的高近一倍。
