| 摘 要： | 通过对陕西省武功县3个葛藤品种根区AM真菌的调查,初步探明了葛藤根区AM真菌资源,为AM真菌在葛藤上的应用提供理论依据。结果表明:AM真菌能与葛藤形成良好的共生关系,不同品种葛藤具有不同的AM真菌生长特性,其定殖率也不相同。总定殖率、泡囊、菌丝定殖率在品种间为:菜葛>粉葛>药葛;丛枝定殖率在品种间为粉葛>药葛>菜葛;孢子密度在品种间为:药葛>粉葛>菜葛。葛藤根区AM真菌资源丰富,土样中AM真菌多为球囊霉属(Glomus),也有少数无梗囊霉属(Acaulospora)和盾巨囊霉属(Scutellospora)的种类。已鉴定出AM真菌20种,其中球囊霉属13种,无梗囊霉属6种,盾巨囊霉属1种。 |

| Abstract: | AM fungi in three varieties of Puerraria were studied in Wugong county of Shanxi,the results showed: there was a good symbiosis relation between Puerraria and AM fungi.Different varieties of Puerraria have the different AM fungus growing characteristic and the colonization.Total colonization,vebuscular colonization and hypha colonization were in the order of Caige>Fenge>Yaoge.Under different host plants,the abuscular colonization was in the trend of Fenge>Yaoge>Caige.The spore density was in the order of Yaoge> Fenge> Caige.The resource of abuscular mycorrhiza in rhizasphere of Puerraria were abundance.Glomus and Acaulospora were primary genera in the Puerraria and Scutellospora was rarely found.Twenty species of AM fungi in three genus,including thirteen species of Glomus,six species of Acaulospora and one species of Scutellospora,were isolated from rhizasphere of Puerraria. |
