胚根鞘

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。

In the early phase of differentiation a series of structural changes occurred at some local areas of the coleorhiza.

胚胎分化时胚根鞘的形态结构特征的变化与营养吸收相联系进行了实验观察。

Both root and root cap are covered by a sheath-like structure called the coleorhiza.

根和根冠被一鞘状结构，即胚根鞘所覆盖。

Up to now, auxin has been the only phytohormone that polar transported.

在胚芽鞘和茎尖生长素是向下运输，在根部是向根尖运输。

The results showed the variation and ranking of genotypes based on the relative value of proline content, SOD and CAT activity of plumule was rather similar to that based on the yield reduction rate in field water deficit experiment.

结果表明，在渗透胁迫条件下，不同小麦品种萌发期胚芽鞘的脯氨酸含量、胚芽鞘和胚根的MDA含量升高，而胚芽鞘和胚根的SOD、CAT活性以及可溶性蛋白质含量下降。

Radical leaves with sheath broadened at base; petiole 30--90 cm; leaf blade triangular or triangular-ovate, 5--15(--25)× 3--15 cm, base sagittate to hastate, apex acute to acuminate.

胚根叶具鞘扩大在基部；叶柄30-90厘米；叶片三角形的或三角状卵形， 5-15(-25)* 3-15 厘米，基部箭头形到戟形，先端锐尖或渐尖。

The changes in activity of glutamine synthetase and NADH-glutamate synthase in endosperms, coleoptiles, and roots were determined during the germination of rice Oryza sativa L.

测定了水稻种子不同萌发时期胚乳、胚芽鞘和幼根的谷氨酰胺合成酶和依赖于NADH的谷氨酸合酶活性变化。胚乳和胚芽鞘的GS活性在萌发过程中升高，幼根的GS活性则有所降低。

Based on the present histological and previous molecular biological studies, the special structure at the apical end is obviously different from the cervical loop giving rise to Hertwig's epithelial root sheath, in human, mouse and rat molar tooth germs.

作者所作的组织学和分子生物学实验结果表明，人类、大鼠及小鼠磨牙牙胚中这种根尖末端特殊的结构与颈环区Hertwig上皮根鞘结构明显不同。

The leaf esterase,endosperm esterase, root esterase and coleoptile esterase zymogram phenotypes in Set II alien addition Lines of wheat-wheatgrass, octoploids of wheat-wheatgrass, common wheat and wheatgrass were analyzed.

本文分析了小冰麦异附加系列II、八倍体小冰麦、普通小麦和天兰冰草的叶片酯酶、胚乳酯酶、根酯酶和胚芽鞘酯酶和酶谱表型。

Winter wheat varieties were used as materials, their coleoptile length, seedling length and main radicle length of wheat seedlings were investigated under different concentrations of PEG-6000 osmotic solution simulated drought stress, and their relations with the yield components and drought tolerance under rainfed and rainout shelters were further analyzed.

以6个抗旱性不同的冬小麦品种为材料，通过不同浓度的PEC-6000渗透溶液模拟干旱胁迫处理，研究了小麦苗期的胚芽鞘长度、苗高、主胚根长等性状，并与其在大田及防雨棚控水条件下的产量构成和抗旱性的关系进行分析。

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。
