【摘要】 以部分黄瓜和甜瓜品种为试材,通过病害抗性组分分析法,对其霜霉病抗性进行了初步研究。结果表明:供试黄瓜、甜瓜品种均为感病品种;其中黄瓜品种"唐山秋瓜精品606"、"水果型101"(唐山秋瓜)、"及早挂满架"、"津研4号"、"绿宝2号"等,甜瓜品种"纯甜时代"、"高糖金玉"等感病较轻,表现为病斑相对较小,病斑数形成较少,病斑产孢囊量较少;黄瓜品种"吉杂4号"、"麻皮黄"等,甜瓜品种"如意"、"金甜佳美"等品种感病较重,表现为病斑相对较大,病斑数形成较多,病斑产孢囊量较多。更多还原

【Abstract】 Taking some cucumber and melon varieties as material,by disease resistant component analysis,the resistance to downy mildew was studied.The results showed that some cucumber varieties,such as ‘Tangshanqiugua 606’,‘Shuiguoxing 101’(Tangshanqiugua),‘Jizaoguamanjia’,‘Jinyan No.4’,and‘Lvbao No.2’,some melon varieties,such as ‘Chuntianshidai’and‘Gaotangjinyu’,were slightly susceptible and showed relatively small disease spots,less number of disease spots and fewer sporangia produced.Others cucumber varieties,such as‘Jiza No.4’and‘Mapihuang’,and melon varieties,such as‘Ruyi’,and‘Jintianjiamei’were the highest susceptible and showed relatively bigger lesion,larger number of disease spots and more sporangia production.更多还原
