摘要
采用组织分离法对滇黄精(Polygonatum kingianum)病害样品进行病原菌分离,进一步通过柯赫氏法则进行验证并通过形态学观察和ITS序列分析方法鉴定该病原菌。结果表明,病原菌菌株的菌丝为白色,背面淡黄色,菌丝体呈絮状、贴基生长、生长茂盛;病原菌菌株的分生孢子有两种形态,大型分生孢子呈镰刀形或柱形,小型分生孢子呈卵形或肾形;从菌株的形态学、致病性测定和ITS序列分析初步鉴定该菌为腐皮镰刀菌(Fusarium solani)。
A pathogen from Polygonatum kingianum was isolated by pathogen isolation method,and identification of the pathogen was carried out by Koch's rule,morphological observation and ITS sequence analysis.The results show that the single colony mycelium of the pathogenic strain is white,the back is light yellow,and the mycelium is flocculent and flourishes.The conidia of the pathogenic strain have two forms,the large conidia are sickle-shaped or columnar,and the small conidia are oval or kidney-shaped.The pathogen was identified as Fusarium solani from the morphological,pathogenicity and ITS sequence analysis of the strains.
