| 摘 要： | 在田间自然发病的条件下,1989～1990年调查不同地区3个大豆品种大豆灰斑病的普遍率和严重度,证明普遍率和严重度的关系都可用 Gompertz 衍生模型描述,而以普遍率小于65％时拟合最好。3个品种的 I-S 关系可用一个通式描述。

| Abstract: | The relationships between incidence and severity(I-S)of frogeye leaf spot of soybean
were studied with data from naturally infected fields.The results showed that the I-S rela-
tionships of disease of three cultivats might be described with Gompertz-derived model.The
best fitness was obtained,when incidence was below 65%.The I-S relationships of three vari-
eties also might be des cribed with one function. |
