11. Authors 'materials showed that all the single, twin and triplet embryoes were situated at the micropylar end in one embryo sac of young ovule and no adventitious embryo was seen outside the embryo sac of ovules.
    在含单胚和多胚颖果中，胚均位于同一胚囊的珠孔端，未见到胚囊以外存在不定胚。
12. The endosperm development follows the nuclear type. The endosperm cells form at the micropylar end, and remain free nuclear phase at chalazal end.
    胚乳发育为核型，珠孔端胚乳细胞化，合点端保持游离核状态。
13. In about 18~ 24 hours, the pollen tube enters the embryo sac and destroys one of the two synergids, releasing 2 sperms in the micropylar end.
    约18～24h，花粉管进入胚囊，破坏一个助细胞，并在其珠孔端释放两个精子；
14. These results suggest that the shape and the size of the micropylar apparatus is favourable for the sperm to penetrate the egg envelop and to block polyspermy.
    研究表明，精孔器的大小与形态有利于精子快速入卵，是精子穿过卵膜的唯一通道。
15. Micropylar collar and operculum are absent in micropylar region.
    珠孔区无珠孔领与孔盖的分化；
16. When the free nuclei of the endosperm were 16 or 32, the nucellar embryo initial ( s) originated from the nucellar cells near the micropylar end of the embryo sac.
    当胚乳游离核达到16或32个时，最早的珠心胚原始细胞由靠近胚囊珠孔端的珠心细胞分化形成。
17. The results are as follows: Allium odorum-type& Callose first occurs in the wall of megasporocyte from the micropylar end, then gradually envelops the whole cell. Megasporocyte is surrounded by the wall with callose during metaphase ⅰ, anaphase ⅰ and telephase ⅰ.
    结果表明，韭型（Alliumodorum-type）胚囊大孢子发生时，自大孢子母细胞的珠孔端细胞壁内出现胼胝质荧光，并逐渐扩展到整个细胞壁，中期Ⅰ至末期Ⅰ细胞壁呈现胼胝质荧光。
18. More initials specialized from one or more layer of nucellar cells in the micropylar region with the ovary growth.
    随着子房生长，多个原始细胞持续不断地从珠孔端靠近胚囊的1至几层珠心细胞中分化出来。
19. And then, it enters the embryo sac by one degenerated synergid, releasing 2 sperms in the micropylar end.
