【摘要】 对从甘肃定西定安区采集的柠条VA菌根真菌进行分离,共鉴定出8种VA菌根真菌:缩球囊霉(Glomus constrictumTrappe),地球囊霉(Glomus gepsporumGerdemann,J.W and J.M.Trappe),集球囊霉(GlomusfasciculatuGerd.&Trappe emend.Walker&Koske),两型球囊霉(Glomus dimorphicumBoyetchko&Tewari),微丛球囊霉(Glomus microaggregatumKoske Gemma&Olexia),苏格兰球囊霉(Glomus caledonium(Nicol.&Gerd.)Gerd.&Trappe),副冠球囊霉(Glomus coronatumGiovannetti)和巨大巨孢囊霉(Gigaspora giganteanGerd.&Trappe)。并对这8种VA菌根真菌的主要形态进行了描述,分析了其侵染情况及结构特征。更多还原

【Abstract】 8 species were obtained from the study of VAM fungal resources in Gansu Dingxi.They were Glomus constrictum Trappe;Glomus gepsporum Gerdemann,J.W and J.M.Trappe;Glomus fasciculatu Gerd.& Trappe emend.Walker & Koske;Glomus dimorphicum Boyetchko & Tewari; Glomus microaggregatum Koske Gemma & Olexia;Glomus caledonium(Nicol.&Gerd.) Gerd.& Trappe;Glomus coronatum Giovannetti;Gigaspora gigantean Gerd & Trappe;The main morphological characters of the eight species were described.The infectious intensity of AMF and the characters of mycorrhizal structure were analyzed.更多还原
