油菜是多花多籽的作物,一般单株有花蕾数百个至千余个,结角率40～70%,结籽率40～80%,品种间或同品种不同部位间均有一定的差异.为了研究结角率与结籽率在各部位的分布规律,降水和温度对它的影响程度,我们连续四年进行(1979～1982)开花结实的观察.
Rape is a flower-rich crop. Generally, there are hundreds to thousands of flower buds per plant, and the rate of node formation is 40-70% and the seed-setting rate is 40-80%. There are some differences among different varieties or varieties In order to study the distribution rule of seedling rate and seed setting rate in each part, the influence of precipitation and temperature on it, we observed the flowering and fruiting in 1979 ~ 1982 for four consecutive years.
