【摘要】 研究证明,采用黄瓜、打瓜和葫芦瓜接种,可以诱发蔓枯病菌形成大量的分生孢子器,从而解决了抗病鉴定时所需大量接种体问题,此种方法简单,材料易得,是一种较好的诱发无性子实体形成的方法。采用该法所形成的大量分生孢子对新疆17个哈密瓜品种进行抗蔓枯病鉴定,证明所供试的品种无免疫品种,发病程度较轻的品种有新蜜杂1号、新蜜19号,其病情指数均在21以下,而炮台1号、伽师瓜、炮台2号、秋霞、天合早黄蜜、87、新蜜16号和新蜜18号感病性较强,病情指数都在50以上。更多还原

【Abstract】 The results showed that a lot of pycnidia can be induced easily on the cucumber, cucurbit and seed-using watermelon after inoculation. The method was first reported in the domestic and resolved the problem when the resistance experiment of hamimelon needs large amount of spores of the pathogen.The method was simple and the material was easy to obtain.17 muskmelon varieties from Xinjiang were evaluated for their resistance by inducting spoeres. The studies showed that the varieties had no immunity. Xinmixa-1 and Xinmi-19 were the varieties with better resistance to the diseases. Its disease index was below 21,while Paotai-1, Jiashimelon, Paotai-2,Qiuxia, and Zaohuangmi were easier to be invaded, the disease index number was above 50.更多还原
