It takes about 0.5 h for a pollen tube from germination to arrive at the micropyle. About 0.5 h after pollination, the pollen tube releases two sperms into one synergid. At 0.5-2.5 h after pollination, the egg cell fuses with one sperm to form a zygote. About 10.0 h after pollination, the division of the zygote begins. The duration of the zygote lasts about 2.5-10.0 h. However, one sperm nucleus fuses with two polar nuclei at 1.0-3.0 h after pollination, and 5.0 h after pollination the primary endosperm nucleus begins to divide.
水稻受精过程经历的时间表如下:授粉后,花粉在柱头萌发;花粉萌发至花粉管进入珠孔大约需要0.5小时;授粉后0.5小时左右,花粉管进入一个助细胞,释放精子;授粉后0.5-2.5小时,精卵融合形成合子;授粉后约10.0小时,合子第1次分裂,合子期为授粉后2.5-10.0小时;授粉后1.0-3.0小时,精核与两极核融合;授粉后约5.0小时,初生胚乳核分裂。

The microspore germination of self-pollination,self-plant-pollination and cross-pollination and the pollination microspore germination in and outside of stigma were observed with fluorescence microscopy.
采用荧光显微镜技术,观察自花授粉、自株花授粉、异花授粉下花粉粒的萌发生长,以及柱头内外授粉花粉粒的萌发情况。

Thus, flowering plant species dependent on insect pollination, as opposed to self-pollination or wind pollination, could be endangered when the population of insect-pollinators is depleted by the use of pesticides.
因此,依赖于昆虫授粉的开花类的植物,因为不同于自身授粉或风媒授粉,在花粉媒虫数量因杀虫剂的使用而减少时,会濒临灭绝的危险。
