核桃仁霉烂病病原菌鉴定及生物学特性研究

Identification and Biological Characteristics of Pathogen of Nut Mildewed Rot

对核桃仁霉烂病痛原菌进行了分离鉴定，并对其生物学特性进行了研究。结果表明，核桃仁霉烂病病原为立枯丝核菌。病原菌最适生长爷件为：25～30℃，pH值5～9，PDA培养基，连续光照。核桃应储存在低温、干燥条件下，以抑制病原菌生长，减少病害的发生。

The pathogen of nut mildewed rot is Rhizoetonia selani and cas grow from 15℃ to 35 ℃. The optimum temperature for hyphae growth is 25 ℃ and pH value, 7. Among the tested carbon and nitrogen resouree： sucrose, glucose and beef extract were beneficial for hyphae growth with lighting.
