摘要(Abstract)：
在温室内,利用松属Pinus、栎属Quercus植物幼苗分别与乳菇属Lactarius、块菌属Tuber中重要食用菌进行菌根合成过程中,发现有9种外源竞争性菌根真菌exogenous competitive mycorrhizal fungi(ECMF)会造成宿主植物污染。形态解剖和分子生物学鉴定结果表明,9种ECMF分属5个属(Amphinema、须腹菌属Rhizopogon、硬皮马勃属Scleroderma、小球孢盘菌属Sphaerosporella、乳牛肝菌属Suillus)5科(阿太菌科Atheliaceae、须腹菌科Rhizopogonaceae、硬皮马勃科Sclerodermataceae、火丝菌科Pyronemataceae、乳牛肝菌科Suillaceae),其中,造成松树苗污染的主要为Amphinema、Rhizopogon和Suillus属的种类,造成栎树苗污染的主要为Scleroderma属的种类,而Sphaerosporella属的种类既能污染松也能污染栎。同时,对ECMF形成菌根的形态与解剖特征进行了描述,以期为菌根合成过程中ECMF污染的识别与控制提供借鉴。
