冬瓜枯萎病菌与节瓜枯萎病菌的差异比较

Studies on Differences Between the Pathogens Brought Wilt Disease in Wax Gourd and Chieh-Qua

摘要: 对冬瓜枯萎病菌Fusarium oxysporum（schl．）f.sp．benincasae与节瓜枯萎病菌F.oxysporum（schl．）f．sp．chichqua在形态、致病力、致病速度、毒素分泌量、寄主范围等方面进行了比较研究．结果表明二者的形态基本相似，但在致病力、致病速度、毒素分泌量、寄主范围等方面均存在较大差异．从而推断冬瓜枯萎病菌与节瓜枯萎病菌可能不是同一病原物．

Abstract: Differences between the pathogens brought wilt disease in wax gourd and chieh-qua were studied. The results showed that two pathogens were similar in shape, while different in ability of infection, speed of infection, the yield of toxin and scope of parasitism,thus indicated that the isolate of wax gourd wilt was not the same as that of chieh-qua wilt.
