摘要
按照Sneh等提出的方法和标准,对草地早熟禾(Poapratensis)和高羊茅(Festucaarundinacea)丝核菌综合症的分离菌株进行了病原菌物种鉴定。鉴定的主要依据包括菌落和菌丝形态、菌核的形态和结构、菌丝顶端细胞核数目等。鉴定结果表明,杭州、西安、宝鸡、杨凌等地引起草地早熟禾和高羊茅丝核菌综合症的病原菌为立枯丝核菌(Rhizoctoniasolani)。
Identification of Rhizoctonia species with Kentucky bluegrass(Poa pratensis)and Tall fescue(Festuca arundinacea)was conducted following the procedures contributed by Sneh et al. The key characters considered were morphology of colony and hyphae,morphology and structure of sclerotia,and cellular nuclear number in young hyphal cells.As the results,the isolates from Zhejian and Shaanxi were identified as Rhizoctonia solani.
