摘　　要：菌核形成与羊肚菌(Morchella esculenta)子实体的形成有密切的关系。以PDA培养基为基础培养基,通过添加其他物质培养羊肚菌菌丝,观察菌核生长情况,从而初步判断其形成菌核的培养基限定条件。结果表明,碳源营养添加物为淀粉和乳糖,浓度为10 g·L^(-1);氮源添加物为NH4HCO3、KNO3和甘氨酸,浓度为250 mg·L^(-1);添加KH2PO4,浓度为1 g·L^(-1),均能较好地促进羊肚菌菌核的形成。Sclerotia formation is relative to the development of Morchella esculenta fruiting bodies directly.PDA medium as the basic medium for M.esculenta sclerotia,by adding other nutrition substances,the affections of different nutrition substances for sclerotia formation were investigated,and the defined condition for sclerotia formation was judged.The experiment results showed,carbon nutrition substances (starch and lactose,10 g·L^(-1)),nitrogen nutrition substances (NH4HCO3,KNO3and glycine,250 mg·L^(-1)) and inorganic chemical (KH2PO4,1 g·L^(-1)) can promote the M.esculenta sclerotia formation.
