| 摘 要： | 以大豆灰斑病菌７号小种的培养基滤液和层析后的粗毒素，对３０个大豆品种的幼苗和叶的致萎初始时间和失水萎蔫程度进行了研究分析，结果指明初始反应时间和失水率是大豆灰斑素效应的两个量化指标，也分别反应其品种的敏感性和受害严重度。滤液和粗毒素，幼苗和叶片鉴定结果以及它们和田间抗性鉴定结果一致性表明毒素可以用来作抗源鉴定，由此建立了大平灰斑病毒素筛选抗源的方法和标准。

| Abstract: | The seedlings and leaves of 30 soybean cultivars were treated with filtrates and rude toxin made from race 7 of Cercospora sojna Hara. The beginning time and degree of wilting were studied. The results showed that the beginning wilting time and water-lost ratio were both the quantitative indexes of toxin effects and the reflections of the sensitivity and serious degree. The screening results of treating with filtrates, as well as between the leaf and seedling method were highly in accordance with each other. The fact suggested rude toxin could be used in the screening of resistant resources. The screening method and standard of resistance treated with toxin from Cercospora sojna were also established. |
