摘　　要：为提高白菜育种中授粉结籽率,并获得最佳的授粉时间,以白菜品种75#为材料,对开花前1d、开花当天、开花后1d和开花后2d的花粉进行活力、萌发率和形态的观察测定。结果表明:开花当天花粉活力最高,开花后2d花粉活力急剧降低,开花前1d与后1d花粉活力相差不大,居于开花当天和后2d之间。白菜育种中选用开花当天的花粉利于受精。ln order to improve the pollination rate of Chinese cabbage and get the best time,taking Chinese cab bage variety 75 # as material,the germination rate and morphology were measured on the day before flowering, flowering, one and two days after flowering. The results showed that pollen vitality was the highest on the day of flowering, and fell sharply on two days after flowering, it were similar on the day before or after flowering in the middle. Pollen on the day of flowering was conducive to fertilize in Chinese cabbage breeding.
