摘要
对四川、浙江、安徽、河北、辽宁等地不同梨品种采集的6个梨黑星菌(Venturianashicola Tanaka et Yamamoto)的单孢分离物,采用鉴别寄主进行致病力测定和菌体酯酶同功酶测定。结果表明:在我国栽培梨上的黑星菌是存在生理分化的。并可将供试6个分离物分成4个类型。
The pathogenicity and esterase isoenzyme of six single spore isolates of Venturia nashicola collected from several provinces of China were identified. The results indicate that the Venturia nashicola in Chinese cultivated pears have physiologic specialization, we can divide the isolates into four types.
