摘　　要：以蛹虫草CM2品种为供试菌株,蛹虫草子实体的产量及虫草素含量为指标,以麦粒为基础培养基,添加5种不同碳氮源,观察对蛹虫草菌丝及子实体生长的影响.结果表明,在5种碳氮源中蔗糖和蛋白胨最有利于蛹虫草子实体生长,子实体在100g培养料中产量分别为57g和55.67g.虫草素含量分别高达15.76mg/g和14.32mg/g.With CM2 cordyceps as the tested strains,the output of Cordyceps militaris and cordycepin as measuring indexes,the wheat berry as basic medium,adding five different carbon source and nitrogen source to observe the influence on Cordyceps militaris mycelium and its sporophore′s growth.Research has reveled that saccharose and peptone in five carbon and nitrogen sources were most conducive to the growth of the Cordyceps militaris.The output of sporophores in 100 g cultivation substrates were 57 g and 55.67 g.The content of cordycepin was as high as 15.76mg/g and 14.32mg/g.
