| 摘 要： | 利用田间调查的数据，分析了稻粒黑粉病病穗率与病粒率的关系和发生程度的分级标准。结果表明，病穗率与病粒率的关系以指数函数拟合较好；在病穗率小于８０％左右时可以用直线方程拟合。病害发生程度可分为５级。

| Abstract: | Based on the data collected in a field investigation,the relationship between diseased paniclerate and diseased seed rate(P-S relationship)of rice kernel smut(Neovossia horrida)was analyzedand the standards for grading its incidence were established.The P S relationship may well bedescribed with an exponential function.It may also be described with a linear function when thediseased panicle rate is below 80%.The incidence of the disease is divided into five grades. |
