胚根

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。

These observations, coupled with the fact that GA stimulated germination of dormant Myrica seeds, provide evidence that endogenous ABA decreased dormancy break and that endogenous gibberellins, especially GA4 and/or GA1 are involved in germination.

此外，观察暖温、低温或暖低温层积处理后的种子胚部GAs含量发现，除了胚根已伸长的种子胚中的GA4含量增加外，其他各处理的GA1， GA3， GA7和GA20含量都很低。

In IR36-Shuang materials, the rate of twin seedlings with single radicle and single plumule axis was higher than that in other types.

在多胚苗材料中，单胚根单胚轴双苗所占的比例相对较大。

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。

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。

The radicle is joined to the hypocotyls and both tissues are derived from the four octants nearest the suspensor.

胚根和胚轴联在一起，两个组织都来自最靠近胚柄的第四个八分体。

Seed vertical, brown, of same shape as utricle; embryo semi-annular; radicle inferior; perisperm scant.

垂直的种子，棕色，相同形状于胞果；胚半环形；胚根下位。外胚乳不够。

Seeds usually 3-angled; testa thin, crustaceous, smooth to reticulate or verruculose, sometimes adaxially invaginated at hilum; endosperm copious; embryo straight to distinctly curved, lacking chlorophyll; cotyledons broader and much longer than radical.

种子通常3倾斜；种皮薄，壳质，平滑到网状或者小瘤状，有时正面在种脐凹入；胚乳丰富；胚直或明显弯曲，缺乏叶绿素；子叶较宽，远长于胚根。

Seed vertical; embryo horseshoe-shaped; radicle inferior; perisperm copious.

种子垂直胚马蹄形；胚根下位。外胚乳丰富。

The root system in the cortex of the host stem has a few branches and highly simplified stele of original triarch vascular bundles. The haustrium root system, which is from the root system in the cortex of a host stem enters the vascular tissues as finger-like body from the vascular rays and then to become hyphae-like body among the vascular cells.

皮层根有少数分枝，无次生结构，中柱结构高度简化，从胚根的结构可看出其初生木质部原先是三原型的；吸器根从皮层根上发生，进入寄主维管射线中，再进入维管组织内，并形成许多丝状体。

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。
