子叶

Seed large, globose, enveloped by membranous endocarp, endosperm present or absent; cotyledons unequal.

种子大的，球状，被膜质内果皮包围，胚乳宿存或无；子叶不等长。

A clearly defined endodermis is seen in all roots and in the stems of the non seed-bearing vascular plants and some dicotyledons.

所有不产生种子的维管植物和一些双子叶植物的茎中都可以清楚的显示出这一结构。

Epicotyl The part of the plumule above the cotyledons.

上胚轴：是子叶着生点以上的胚轴部分。

Results showed that the monochromatic lights were advantageous to the Pchlide reduction and biosynthesis for etiolation seedling of Phaseolus radiatus in illumination for 0.5 h at first. The monochromatic light did not favor for Chlide esterification after illumination for 2 h. Chlide esterification was controlled by the cell nucleus gene, because Chlide esterification rate was restrained to the seedling leaf of P. radiatus.

结果表明：绿豆黄化幼苗在光照最初0.5h，单色光有利于Pchlide的还原和新Pchlide的生物合成；光照2h后，单色光不利于Chlide的酯化；CH明显抑制绿豆幼苗子叶Chlide的酯化速度，说明Chlide的酯化是受细胞核基因控制。

A diarch or triarchsiphonostele with exarch primary xylem was found at lower cotyledonary node zone.

果表明：银杏幼苗的轴向器官以子叶节区下部的初生维管结构先建立，其中柱类型是外始式二原型或三原型管状中柱

Keep fenugreek leaves in warm water for 10 minutes and blend to powder.

葫芦巴子叶浸於暖水约10分钟，磨成粉状。

In M3 generations, 40 mutants of leaf, stalk, flower, seed and cotyledon were obtained by treatment of 60Go γ rays, and 145 mutants by EMS.

结果在M3代分别获得40份和145份叶、茎、花、种子、子叶等性状变异的材料。

Seeds 2 or 1 by abortion, ovoid or ellipsoid, on carunclelike strongly tapered funicle; testa crustaceous, endosperm absent; cotyledons thick, plano-convex.

种子2或1 败育，卵球形的或椭圆形的，生于种阜状强烈渐减的珠柄；壳质的种皮，缺席的胚乳；子叶厚，平凸。

The plantlets of soybean, cucumber and garden balsam were inoculated by wild-type Agrobacterium rhizogenes K599, and hairy root was induced on inoculated sites in vivo. The frequencies of hairy root induction from wound cotyledons of soybean, cucumber and garden balsam were 100%, 65% and 91%, respectively.

利用野生型的发根农杆菌K599对属于不同科属的大豆、黄瓜和凤仙花进行活体感染实验，结果表明，发根农杆菌K599可使切割后的大豆、黄瓜和凤仙花子叶形成不定根，生根频率分别为100%、65%和91%。

Of or relating to seed germination in which the cotyledons remain below the surface of the ground.

地下生的，地下产生子叶的种子萌芽的，或与之有关的，在这种萌芽里胚胎保留在地表面以下

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
