To study the diversity of ectomycorrhizal fungi associated with Picea asperata in Xin Jiashan Forest of Qinling Mountains.
This method combined the field investigation, morphological and molecular biology to identify ectomycorrhizal fungi.
There were 37 different ectomycorrhizal fungi under 14 genera of 10 families on spruce in Xin Jiashan Forest of Qinling Mountains, 34 types belonged to Basidiomycetes, 1 to Ascomycete and 2 to unknown species. Among these identified ectomycorrhizal fungi types, Inocybe sp. was the dominant group; Russula nauseosa was the most dominant species; Hygrophorus sp., Tomentella coerulea, Inocybe sp. 1, Helotiaceae sp. and Lactarius deterrimus were common species; and the rest species were rare species.
The large number but relatively rare species of dominant family and the small number but relatively more species of rare family survived in ectomycorrhizal fungal communities of Picea asperata. For the extreme degradation in arid area of western ecological system, identifing some rare family for further development and utilization had very important practical significance.
研究秦岭新嘉山林区云杉外生菌根真菌的多样性。
采用野外调查、形态学和分子生物学相结合的方法鉴定外生菌根真菌。
秦岭新嘉山林区云杉上有10科14属37种不同的外生菌根真菌，其中担子菌门34种，子囊菌门1种，未知种类2种。在这些已鉴定的外生菌根真菌类型中，丝盖伞属为优势类群；恶心红菇为最优势种； Hygrophorus sp.、蓝绒盖牛肝菌、丝盖伞属1、Helotiaceae sp.和辣味乳菇为常见种；其余为稀有种。
云杉外生菌根真菌群落中优势科种类多但相对稀少，稀有科种类少但相对较多。针对西部生态系统干旱地区的极端退化情况，鉴定一些稀有科进行进一步开发利用具有非常重要的现实意义。
