In the late of April of the second year, male inflorescences unbound and pollinated. When female inflorescences accepted the pollen grains, ovary development was increased in early May. With the development of either of the two ovule, funiculus, integument and nucellus were differentiated. Embryo sac mother cell came into being and the meiosis begins. Then fuctional megaspore developed into matured embryo sac that contain eight nucleuses. In the end of May, double fertilization generated.
