胚根

In order to understand the mechanism of action of ComCat, agronomic农艺学 parameters such as seed germination, root and coleoptile development in seedlings as well as seedling establishment, vegetative growth and the effect on final yield were monitored under laboratory and field conditions.

为了帮助理解碧护/康K的作用机理，一些农艺学的参数如：种子发育，根和胚芽鞘在秧苗和秧苗培植期，植物成长和提高最后收成在实验室和大田进行了跟踪和采集。

All the contents of Extractable heavy metal like Pb, Cu, Zn and Cd in limestone slagged wasteland are higher than those in contrapositive soil nearby. The slag filtrate has no effect on seed germination rate of Mung beans, Broad beans and Corns but restrains their germination vigor and protraction of hypocotyls with root restraint rate exceeding 30-50%; While it has an apparent effect on germination rate and germination vigor of sensitive seeds like Beans with P=0.05. Simulate to plant the 4 different seeds in pot for a month, Test groups have a lower data in total leaf area, plant height and weight but a much higher content of protective materials like PRO and MDA in biochemical mensuration experiment compared with CK group.

石灰炉渣废弃地中Pb、Cu、Zn、Cd重金属有效态含量均高于临近对照土壤，其炉渣淋出液对绿豆、蚕豆、玉米3种植物种子发芽率无影响，但均抑制其发芽势和下胚轴伸长，根长抑制率达30%~50%以上，对敏感种子黄豆的发芽率、发芽势（4d）影响明显，摸拟盆栽一个月苗期，4种植物试验组在总叶面积、株高、生物量方面均低于对照组；生理生化测定，4种植物其体内抗逆性保护物质脯氨酸和膜过氧化产物丙二醛含量试验组均高于对照组。

In the third chapter,we study mainly iterative roots of piecewise homeomorphic maps of an Y-star.

在第三章，我们主要研究了Y星上逐片同胚映射的迭代根的问题。

In this paper, we discussed mainly the iterative roots of piecewise homeomorphic maps of an Y- star.

本文主要讨论Y星上逐片同胚映射的迭代根。

In the second chapter,we introduce some lemmas and concepts about iterative roots of piecewise homeomorphic maps of y-stars.

在第二章，我们介绍了与Y星上逐片同胚映射的迭代根有关的概念和引理。

In addition to this, shoots were differentiated on hypocotyl segments cocultivated with A.

除此之外，共培养后的下胚轴切段在发根的同时也分化出幼苗。

In the range of 20-40g/L, the growth rate of hypocotyl calli of A. crenata was positive to sucrose concentration.

在20-40 g／L范围内，朱砂根的下胚轴愈伤组织生长速率随着蔗糖浓度的升高而升高，50 g／L的蔗糖降低愈伤组织的鲜重增长率，但提高干重增长率。

In cotyledon, on one hand, very weak GUS staining was observed in PARF8:GUS, but very strong was found in phyA-209 PARF8:GUS. In the shoot apical meristem, hypocotyle and root tip, on the other hand, phyA-209 PARF8:GUS exhibited weaker GUS activity than PARF8:GUS. Interestedly the same expression patterns of ARF8 resulting from disruption of PhyA have been observed in dark, white-light and far-red-light conditions.

结果表明，无论在黑暗、白光和远红光条件下，PhyA突变均明显提高幼苗子叶和叶片中ARF8的表达水平，但明显降低幼苗下胚轴、茎尖和根尖中的表达水平。

Under light microscope, the egg is an oblated and agglutinated demersal with a narrow perivitelline space; eggs ranged in diameter from 1.95 to 2.38 mm with a mean of 2.18 ± 0.03 mm; their membrane are smooth and they have 5 to 7 cannular keratose egg-filaments; the oil globules are multiple, ranged in diameter from 0.05 to 0.50 mm and in number from 7 to 145 with a mean of 28±2, the position of them migrate during embryonic development; the yolks are ivory-white with no segments, ranged in diameter from 1.00 to 2.30 mm with a mean of 1.90 ± 0.03 mm; the development phases of the embryo are variable. So they were identified as the eggs of one Beloniformes.

在光学显微镜下：卵呈微扁圆形，卵径1.95~2.38mm，粘着沉性；卵黄间隙较窄，卵黄囊呈乳白色，无龟裂；卵膜平滑，在其表面有5~7根细长角质管状卵膜丝；多油球数不定（4~145），油球径0.05~0.50mm，油球在卵黄囊中的位置随不同的发育时期而不断发生变化；胚体处在不同的发育阶段，其特征符合颌针鱼目鱼卵的特征。

The proteins from endosperm, root, stem, leaf, leafstalk of Jatropha curcas L. and their calli were hybridized the seed toxin protein of Jatropha curcas L. by Western blot.

然后我们以麻疯树的胚乳、根、茎、叶、叶柄及其诱导出的愈伤组织为材料，对麻疯树种子毒蛋白作Western-blot杂交。

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。
