胚

After lOmin delay only 81.2% pronucleus developed to blastula, significantly lower than control (93.2%).

滞留20min不引起原核胚、2-cell胚胎和桑椹胚以及囊胚的死亡。

Seeds with straight embryo, with or without endosperm; radicle curved upward or downward.

种子具直立的胚，有或没有胚乳；胚根向上或者向下弯曲。

However,the combination of BA with IAA promoted thededifferentiation and redifferentiation,though the regeneration frequency differed in kindsof combinations,among which the combinations of 2.0-3.0 mg/l BA + 0.5 mg/l IAAproduced a highest differentiation frequency of 70％or so.

在仅添加了BA的分化培养基上，下胚轴脱分化和再分化都比较困难，而BA和IAA配合使用时却能很好地促进下胚轴的脱分化和再分化。不同BA和IAA配比组合中下胚轴的不定芽分化率存在差异，其中以BA2.0-3.0mg/l+IAA 0.5mg/l组合的不定芽分化率最高，均达到了70％左右。

Then replate them onto feeder layer culture system (containing leukemia inhibitory factor) in order to passage and expand. Subsequently we identified the expanding cells by alkaline phosphatase staining, karyotype analysis and the formation of embryoid body which are typical characteristics of ESCs.

以分离培养的细胞作为供体细胞，近交系C57BL/6J为受体囊胚供者，采用囊胚注射法构建嵌合胚，体外恢复培养后移植进动情期子宫中，结果生出了黑白杂合的嵌合鼠。

Fruit a winged schizocarp, commonly a double samara, usually 1-seeded; embryo oily or starchy, radicle elongate, cotyledons 2, green, flat or plicate; endosperm absent.

通常，果飞行的分果相似物，通常1种子；胚油性或淀粉的，胚根拉长，子叶2，绿色，平的或折扇状的；无胚乳。2n = 26。

Seeds ellipsoid to pyriform, dull to ± shiny; seed coat with thick inner layer of dense black sclerenchyma surrounded by outer layer of compact parenchymatous tissue; endosperm copious; embryo straight or nearly so; cotyledons ovate to elliptic, flattened; hypocotyl superior.

种子椭圆形到梨形，黯淡到发亮；种皮具厚的紧密黑色的厚壁组织内层，被紧密的薄壁组织外层所包裹；胚乳丰富；胚直立或近直立；子叶卵形到椭圆形，扁平；下胚轴上位。

Seeds remaining attached in dehisced fruit; seed coat with thick inner layer of dense black sclerenchyma and spongy outer layer bounded externally by a shiny black pellicle; endosperm copious; embryo straight or slightly curved; cotyledons elliptic, flattened; hypocotyl superior.

种子附存于开裂的果中；种皮具厚的内层深黑色厚壁组织和海绵状的外层，其外部边界具发亮的黑色表膜。胚乳丰富；胚直或稍弯曲；子叶椭圆形，扁平；下胚轴上位。

Seeds ovoid to reniform; seed coat with thick inner layer of dense black sclerenchyma and spongy outer layer bounded externally by a shiny black pellicle; endosperm copious; embryo straight or slightly bent; cotyledons ovate to elliptic, flattened; hypocotyl superior.

种子卵球形到肾形；种子涂上厚内部层紧密的黑色的sclerenchyma 和海绵状的外部层通过一发亮的黑色的表膜外部束；胚乳丰富；胚稍弯曲的直的或；子叶卵形到椭圆形，扁平；下胚轴上位。

With high oil corn 115 as CK, the embryo, endosperm, seed capsule and the accumulation law of their corresponsive oil in grains of 2 varieties of micro-endosperm super-high oil corn were studied.

方法以高油玉米115为对照，研究2种微胚乳超高油玉米籽粒的胚、胚乳、种皮及相应油分的积累规律。

The so-called AT-algebras are inductive limits of finite direct sums of matrices over the extension algeras of circle algebra by K, where K is the C~*— algebra of all compact operators on a separable infinite dimensional Hilbert space.

若V_*与V_*同构，且保持单位元等价类；T与T仿射同胚，且同构映射与同胚映射相容，则存在E与E′的同构导出上述同构和同胚，所谓AT-代数即为圆代数通过κ的本质酉扩张的矩阵代数的有限直和的归纳极限，这里κ为可分的无限维复Hilbert空间上的紧算子全体，不变量中的V*为三变元Abel半群，T为迹态空间，[1]为单位元所在的Murray-von Neumann等价类，r_E为连接映射。

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。
