When the embryo reached the prehatching stage, the hatching enzyme granules were secreted into the perivitelline space from the top of HGCs.

孵化酶进入卵周液，对卵膜内层进行消化和降解，使胚胎破膜而出。

When the embryo reached the prehatching stage, the hatching enzyme granules were secreted into the perivitelline space from the top of HGCs. Secretory granules were spherical and 0.5-1.0 μm in diameter. The hatching enzyme was dissolved in the perivitelline fluid, where it gained access to the egg envelope and digested the inner layer of the egg envelope.

至孵化前期时，孵化酶颗粒自HGCs顶部的开口分泌出来，分泌颗粒呈圆球形，直径为0.5-1.0 μm，有的以单体的形式存在，有的粘结成团。

Bractlets rudimentary, membranous, scale-like, hidden by perianth; stigmas papillose or hairy throughout; embryo planospiral.

In the present study, the autotetraploid rice IR36-4X was treated with ion implantation technique by nitrogen ion beams and a polyembryonic seedling mutant (named as the IR36-Shuang) was identified in M2 generation. The mutant line was systematically investigated about the location of seedling in polyembryonic seedling, and the cytological initiation of the additional embryo in the 1R36-Shuang was observed and determined.

以低能氮离子束为诱变源，通过对同源四倍体水稻品系&IR36-4X&进行离子注入后在其第2代群体内筛选得到了1株具有多胚苗性状特征的突变株（IR36-双），对该突变株后代的多胚苗形态特征及其多胚来源进行了研究。

Intracytoplasmic sperm injection, which is a new technique of embryo engineering of domestic animals, can solve the problem of porcine polyspermy.

In an attempt to promote the efficiency in citrus breeding and estimate the pos- sibility of embryo culture applied to citrus production,we carried out the culture technique in the hybrid embryos(Citrus sinensis Osbeek×Poncirus trifoliata Raf.).

为了提高柑桔杂交育种效率和探讨胚培养在柑桔生产上应用的可能性，我们研究了锦橙×枳(Poncirus trifoliata Raf。)的杂交种子胚培养技术。证明：怀特培养基+IAA(1ppm)+CH(600ppm)和 MT 培养基+GA(1ppm)能使第五个小胚萌发成苗；在 MT 培养基+2，4-D(0.7ppm)+BA(0.23ppm)上，有些胚先形成愈伤组织，然后从原有的胚中生根出苗。
