1Both sexual and apomictic embryo sacs were co-existed which belonged to facultative apomixis.

2在有性生殖胚囊中，可观察到完整的八核胚囊。

Seeds enclosed by fleshy edible aril; endosperm fleshy or thick; embryo curved; cotyledon broad and flattened.

种子被肉质可食用的假种皮包围；胚乳肉质或者厚；胚弯曲；子叶宽和扁平。

The growth of radical and hypocotyls time of seed was delayed by long time natural store and refrigeration, and the condition of long time natural store for Atriplex canescens seed's vigor was the worst.

长时间自然存放和冷藏均会推迟四翅滨藜种子胚根和胚轴的延伸日期，且长时间自然存放推迟的更晚。得出长时间自然存放使种子的活力降低最快。

But the abnormal phenomena in autotetraploid rice were more than that in diploid rice.

同源四倍体水稻胚囊发育过程与二倍体基本一致，但在同源四倍体水稻胚囊的形成和发育过程中出现了较多的异常现象。

So, the abnormality of embryo sac was one of the factors that induce low seed setting percentage in autotetraploid rice.

从对13个品种的成熟胚囊育性调查的结果来看，同源四倍体水稻胚囊育性是影响其结实率的原因之一。

Embryo development and origin of twin-embryo of autotetraploid rice with twin-embryo seedlings were observed and verified.

利用激光扫描共聚焦显微技术对同源四倍体双胚苗水稻的受精过程、胚胎发育过程和双胚来源进行观察鉴定。

The structure and expression pattern of each storage protein was investigated using one-dimensional SDS-PAGE. Our results showed that the protein content of each fraction in endosperm of autotetraploid rice line is mostly higher than that of its corresponding diploid rice line.

结果表明：同源四倍体水稻胚乳蛋白各组分含量与相应的二倍体相比，大部分呈增加趋势；同源四倍体水稻胚乳蛋白的亚基类型与相应的二倍体水稻基本一致，仅在全蛋白电泳和清、球蛋白电泳中各发现1条差异条带。

Objective To investigate the effect of different splitting solutions and decompaction treatment on the bisection of mouse embryos at morulae and blastocysts stage and their subsequent transfer after cultured.

目的 研究不同分割液和分割前胚胎去致密化与否对昆明白系小鼠的桑椹胚和囊胚的徒手分割以及分割后胚胎移植的影响。

Yet, all being well, it will become one—for a blastocyst is an early stage in embryonic development.

然而，如果这些胚泡细胞发育得当，它们的确可以生长成一个人，因为胚泡是胚胎发育的早期阶段。

It is concluded that the initial ancotomic site of blood island genesis may be is mesoblast of extraembryonic blastoderm rather than the yolk sac; the blood vessel endothelium cells and the blood cells are generated parallel; the PGCs are the common ancestry of angioblast and HSC.

血岛最早发生的解剖位置可能不是卵黄囊而是胚外胚盘中胚层，血管内皮细胞与血细胞平行发生，PGC是成血管－造血干细胞的共同祖先。

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。
