胚乳

The secondary nuclei can fertilize normally and form nuclear type endosperm while some constitute cellular endosperm, All of them degenerate 12 days after pollination,with the result of the ovules being aborted earlier while the arillus still occur and develop into seedless fruit finally.

次生核虽正常受精，并产生核型胚乳，有的还能发育到细胞型胚，到 12d左右也完全退化。结果导致胚珠极早败育，但假种皮仍能发生发育，最终形成无核果实

There are commonly eight nuclei in the embryo sac: the egg apparatus at the micropylar end, made up of an gee nucleus and two synergid nuclei; three antipodal cells at the oppsite chalazal end that probably aid embryo nourishment; and two polar nuclei in the center that fuse to form the primary endosperm nucleus.

通常胚囊中有8个核，卵器在珠孔端，由卵和两个助细胞组成；3个反足细胞在合点端，可能为胚胎提供营养；胚囊中央有2个极核，融合在一起形成最初的胚乳核。

The genetic effects of the embryo and endosperm genes on rice seedling biomass at early stages were investigated in this paper.

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
