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.
