Some investigations suggested that cyclins and CDK played an important role in the regulation of endomitosis of megakaryocyte. However, the mechanism of cyclins and CDK in the regulation of endomitosis of fetal megakaryocytes during ontogenesis and the relationship between cyclins/CDK and retardation of endomitosis of fetal mgakaryocyte is totally unknown.

Both the new peniculus 1 and the old haplokinety separated at the telophase.The two germinal rows germinal rowsfor both the daughter cells appeared almost at the same time;(2) The macronucleus became shorter and thicker, finally oblate during the division of the cell. Then the macronucleus restored its original shape, band-like form. The micronucleus were divided into two before the macronucleus division;(3) The original scopula and stalk contributed to the old cell. The new cell formed scopula gradually after the cell division.

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.
