胚根

Vascular tissue of the cotyledonary-stage somatic embryos from the two cotyledons to radicle presented V or Y shape.

子叶胚的维管组织从两片子叶伸向胚根，呈V形或Y形。

Seeds with bony tegument; endosperm thin; cotyledons oblate, rounded; radicle short.

种子有多骨的皮；胚乳薄；子叶扁球形，绕行；胚根短。

As for wampee seed, the dormancy was kept for 12 months with germination percentage above 90% but no growth of plumule, though the rabicle elongated.

黄皮再进入休眠，12个月后种子发芽率能达90％以上，但胚芽不伸长，胚根伸长；24个月后休眠解除，幼苗正常生长。荔枝能贮藏6个月。

Seeds were germinated at eleven salinities (0,20,40,60,80,100,120,140,160,180,200 m mol/L NaCl) and germination percentage, rate of germination, as well as seedling growth were measured to detect the differences amang three cultivarscline.

在0，20，40，60，80，100，120，140，160，180，200m mol/L浓度NaCl胁迫条件下，研究了发芽率、发芽指数，并比较分析了胚根、胚轴生长状况。

Seeds numerous, apically comose; embryo straight, cotyledons as long as radicle.

种子多数，顶部具丛毛；直接的胚，子叶倍于胚根。

Seeds linear, elongated, not beaked, apex comose; endosperm copious; cotyledons linear, flat, radicle superior.

结子线形，拉长，不发，先端；胚乳丰富线形，平的子叶，上位的胚根。

The results showed that the extracting liquor of Rhytidium rugosum, Rhytidiadelphus squarrosus, Anomodon minor subsp. Integerrimus, Racomitrium japonicum and Conocephalum conicum have obviously promotive effect on the growth of the main radicle and germ of Zea mays. The extracting liquor of seven species of bryophytes all have restrictive effects on the increasing number of the lateral roots.

结果显示：垂枝藓、粗枝拟垂枝藓、牛舌藓扁枝亚种、东亚砂藓和蛇苔明显促进了玉米主胚根和胚芽的生长。7种苔藓植物配子体水提液均表现出抑制玉米侧根数增加。

Seeds 1 per locule; testa 2-layered; outer layer black, shiny, crustaceous; inner layer thinner; embryo spirally curved, radicle short.

种子1每室；种皮2分层；外部层黑色，发亮，壳质；内部层薄；胚螺旋弄弯，胚根短。

In this research, many indices of drought resistance during germination stage and seedling stage were chosed to evaluate comprehensively the drought resistance of 20 Dactylis glomerata L. germplasm from abroad.

以国外引进的20份野生鸭茅种质资源为研究材料，通过萌芽期PEG模拟干旱试验、幼苗期温室盆栽试验，系统测定了干旱胁迫下鸭茅种质萌芽期种子萌发抗旱指数、胚根、胚芽，幼苗期幼苗株高、根冠比、叶片水分饱和亏缺、质膜透性、脯氨酸含量等形态和生理指标，全面分析了这些指标的变化规律，对所引进的20份鸭茅种质的抗旱性进行了综合评价。

Seeds solitary, exalbuminous; testa membranous; cotyledons usually membranous, contortuplicate, rarely fleshy and planoconvex; radicle superior.

种子单生，无胚乳；种皮膜质；子叶通常膜质，卷折，很少肉质和平凸；胚根上位。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
