摘　　要：以内蒙古及周边地区樟子松的外生菌根为材料,采用形态解剖学与分子生物学手段相结合的方法,对与樟子松共生的外生菌根真菌多样性进行了全面调查及研究,并将所测序列在Gen Bank中进行比对。结果表明:在内蒙古及周边地区与樟子松共生的外生菌根真菌共19种,担子菌15种,子囊菌4种,分别来自于丝膜菌属(Cortinarius)、丝盖伞属(Inocybe)、牛肝属(Suillus)、蜡壳耳属(Sebacina)、红菇属(Russula)、乳菇属(Lactarius)、棉革菌属(Tomentella)、黏滑菇属(Hebeloma)和空团菌属(Cenococcum)、块菌属(Tuber)、口蘑属(Tricholoma)。表明樟子松外生菌根真菌多样性相对较高,且与利用地上子实体鉴定的外生菌根真菌种类有一定的区别。The primary study on the diversity of ectomycorrhiza associated with Pinus sylvestris var mongolica in Inner Mongolia surrounding area was investigated using morphological,anatomical and molecular method,and the sequences obtained were blasted using Gen Bank. The results indicated that there were 19 species different ectomycorrhizas on Pinus sylvestris var. mongolica in Inner Mongolia area. Among these 19 species ectomycorrhizas fungi,3 species belong to Ascomycotina and the rest species belong to Basidiomycotina,they belong respectively to Cortinarius,Inocybe,Suillus,Sebacina,Russula,Lactarius,Tomentella,Hebeloma,Cenococcum,Tuber,Tricholoma. The results showed that the diversity of ectomycorrhizas on Pinus sylvestris var. mongolica was high,and it was different with results identified by fruiting body associated with Pinus sylvestris var. mongolica.
