Ectomycorrhizal (ECM) fungal communities of Quercus liaotungensis of different ages (seedlings, young trees and mature trees) in the growing seasons (June and September) between 2007 and 2009 were studied in a temperate forest of northern China. A total of 66 ECM fungal taxa were identified based on ECM morphotyping, PCR-RFLP, and DNA sequence data. Of these fungal taxa, 51 were Basidiomycetes (77.3%) and 15 were Ascomycetes (22.7%). Cenococcum geophilum was the dominant species. Thelephoraceae (16 taxa), Sebacinaceae (12 taxa) and Russulaceae (seven taxa) were the most species-rich and abundant ECM fungi, accounting for 19.5%, 17.6% and 8.3% of the total ECM root tips, respectively. Results of multiple response permutation procedure (MRPP) analysis indicated that there were marginally significant effects of tree ages (A = 0.01801, P = 0.054) and growing seasons (A = 0.01908, P = 0.064) on the ECM fungal species composition of Q. liaotungensis in a temperate forest.
对中国北方温带森林中不同年龄（幼苗、幼树和成熟树）辽东栎（Quercus liaotungensis）在 2007 年至 2009 年生长季节（6 月和 9 月）的外生菌根（ECM）真菌群落进行了研究。基于 ECM 形态分型、PCR-RFLP 和 DNA 序列数据，共鉴定出 66 种 ECM 真菌类群。这些真菌类群中，有 51 种为担子菌（77.3%），15 种为子囊菌（22.7%）。共生球腔菌（Cenococcum geophilum）是优势种。栓菌科（Thelephoraceae）（16 个分类群）、Sebacinaceae（12 个分类群）和红菇科（Russulaceae）（7 个分类群）是物种丰富度和丰度最高的外生菌根真菌，分别占总 ECM 根的 19.5%、17.6%和 8.3%。多重响应置换过程（MRPP）分析的结果表明，树龄（A=0.01801，P=0.054）和生长季节（A=0.01908，P=0.064）对温带森林中辽东栎的 ECM 真菌物种组成有轻微显著影响。
