以秦岭辛家山林区红桦为研究对象,通过野外调查结合形态学和分子生物学方法,观察鉴定与其共生的外生菌根真菌.结果鉴定出33种外生菌根真菌,均为担子菌,分属8科9属,其中毛革菌属Tomentella是优势类群,Piloderma lanatum、Russula 1、Russula 5、Sebacina cystidiata、Tomentella 1是常见种,其余28种为稀有种.样地1和样地2的丰富度指数、Simpson指数、Shannon指数、Pielou均匀度指数、侵染率均有一定差异,Jaccard相似性指数和Sorenson相似性指数分别为0.27和0.43.说明秦岭辛家山红桦外生菌根真菌资源相对丰富,并且红桦林型在种群建立(幼龄)时外生菌根真菌多样性指数及侵染率均高于种群稳定(中龄)时期.
Diversity of ectomycorrhizal fungi associated with Betula albosinensis in Xinjiashan forest region of Qinling Mountains
The diversity of ectomycorrhizal fungi associated with Betula albosinensis in Xinjiashan forest region of Qinling Mountains was investigated by using the combination of field investigation and morphological and molecular identification methods.The results showed that there were 33 taxa of ectomycorrhizal fungi under nine genera of eight families;all of them belonged to basidiomycetes.Tomentella was dominant;Russula 1,Russula 5,5ebacina cystidiata,Tomentella 1 were common.Richness index,Simpson index,Shannon index and Pielou evenness index of these ectomycorrhizal fungi were discrepant between site 1 and site 2.Jaccard index and Sorenson index were 0.27 and 0.43,respectively.It is suggested that ectomycorrhizal fungi associated with B.albosinensis in Xinjiashan forest region are relatively abundant,and the diversity index and infection rate in young B.albosinensis population were higher than those in stable-aged population.
