摘要
以天津、北京地区主要市售的24个黄瓜品种为试材,以黄瓜棒孢叶斑病菌株为供试菌,采用苗期喷雾法,研究了黄瓜主栽品种对黄瓜棒孢叶斑病的抗性。结果表明:黄瓜棒孢叶斑病菌株最适接种浓度为1×10~4个孢子·mL^(-1),筛选出2个黄瓜棒孢叶斑病高抗品种"津优38号"和"津优305号"。
Taking 24 cucumber varieties from market of Tianjin and Beijing as materials,Corynespora cassiicola as tested bacterial strain,using nebulization method in seedling stage,the resistance of different cucumber varieties to Corynespora cassiicola were investigated.The results showed that the optimal inoculation concentration in identification of seedling stage was 1×10^4 spores·mL（-1）,cucumber varieties ‘Jinyou No.38＇ and ’Jinyou No.305＇ displayed good and stable resistant to Corynesporaleaf spot.
