摘　　要：以黑皮冬瓜为材料,探讨不同授粉时间和次数对冬瓜人工杂交制种效果的影响。结果表明,开花当天上午8:00授粉,其座瓜率最高,但上午9:00授粉的单瓜种子数最多;试验结果还表明,授粉次数对种子质量没有显著影响,但在上午(8:00～10:00)进行两次重复授粉能大幅度提高单瓜种子数。The black wax gourd was pollinated during the flowering day to study the effect of different pollination time and repeated pollination times on hybrid seed production. The results showed that the fruit rate was the highest when black wax gourcl pollinated at 8： 00 am,while the highest seed number per fruit was got when pollination was carried out at 9：00 am. Repeated pollination times had no significant effect on seed quality, while two times increased seed number per fruit in the morning （8：00-10：00 am）.
