Then, the male and the female pronuclei contact with each other and fuse to form the nucleus of zygote, which divides into two daughter nuclei. 雌、雄原核彼此接触,最后融合成合子核,随后分成两个子核。
About 12-24 hours after pollination zygote is in dormancy, at this time primary albuminous nucelus has become to develop continually, a large number of albuminous free nuclei distributed between embryo sac and caeca. 在授粉后12&24小时,合子休眠时,初生胚乳核已开始不断分裂,大量的胚乳游离核分布在胚囊和盲囊中间。
The primary endosperm nucleus was division before the dormant zygote and formed two free nuclei endosperms. The endosperm free nuclei continue to division and formed a circle of free nuclear layer along the embryo sac wall. 初生胚乳核先于休眠的合子进行分裂,形成两个游离的胚乳核,胚乳游离核再经过多次分裂形成多个核,呈游离状态分布在胚的周围,并沿胚囊壁形成一圈游离核层。
Until the next Mid-April, the zygote starts to divide. At this moment, the endosperm nuclei has divided several times. 到次年4月中旬,合子开始分裂时,胚乳核已分裂多次。
