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.

同时，新仔虫的第一咽膜(P′1)也开始由老单毛基索复制，并在细胞分裂后期与老结构分离；(2)大核在虫体分裂过程中由长带状逐渐缩短变粗至扁圆形，于虫体即将分开时迅速拉长，然后分裂为二个新大核；小核分裂先于大核，在两仔虫口纤毛器即将分开时完成；(3)原帚胚及柄归属老仔虫，新仔虫的帚胚在虫体分裂后逐渐形成，柄内肌丝则在柄鞘形成后逐渐长出。

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。

It was showed that throughout the nuclear division, nuclear membrane did not disintegrate,lamina always existed; But only one lamin peptide (similar to lamin B in higher eukaryotes) was expressed during division,ant its expression quantity changed according to the progress of division: in interphase, lamin was constant; when entering G1 phase, lamin increased sharply; then, increased slowly untill division finished.

结果表明：在整个核分裂过程中，核膜不崩解，核纤层结构一直存在；但随着分裂的进展，始终只有一种成分（类似于高等生物lamin B ）的表达；其表达量随着分裂时相的推移而变化：间期时，比较恒定，进入G1期时明显增加；以后不断略有增加，直到分裂完成。
