endosperm n.【植物;植物學】胚乳。

endospermous

Aleurone grain ( aleurone body ) a modified vacuole found in the embryo and endosperm of seeds and containing mostly reserve proteins , but also phytic acid and various enzymes associated with mobilization ( digestion ) of these reserves 糊粉粒(糊粉體) :在種子胚或胚乳中發現的經過修飾的液泡,里面包含許多儲藏蛋白,植酸和各種各樣的酶。

A review about current progress in understanding biochemical processes of starch synthesis in developing cereal endosperms , with an emphasis on the molecular biology aspect of key enzymes involved in the processes 綜述了禾谷類作物胚乳淀粉合成生化過程的近期研究進展,對淀粉合成關鍵酶的生理和分子生物學研究現狀做了重點介紹。

As an effective evolution strategy of angiosperms , double fertilization can enhance the survival of the embryos , seeds and seedlings in which endosperms play a key role in the development of seeds and embryos 摘要雙受精是被子植物的一個有效的進化策略,增加了胚和種苗成活的機會,其中胚乳在胚以及種子發育中至關重要。

However , a small minority of angiosperms that perform apomixsis can overcome the effect of genomic imprinting to normally develop its endosperms without fertilization or with false fertilization 然而極少數進行無融合生殖的被子植物,它們的胚乳可以在假受精或不受精的情況下克服基因組印記效應的影響且正常發育。

Albumin one of a group of simple , lowmolecular - weight proteins found in plants , for example in the endosperm of barley and wheat seeds . albumins are watersoluble and coagulate when heated 清蛋白(白蛋白) :在植物中發現的一種水溶性的、簡單的低分子量的蛋白質。存在于大麥或小麥種子的胚乳中。

Double fertilization the fusion of one pollen nucleus with the egg to form the zygote and of the other pollen nucleus with a polar nucleus to form the triploid endosperm nucleus 雙受精:指花粉粒中的一個精子與胚珠中的卵細胞結合形成受精卵,另一個精核與極核結合形成三倍體的胚乳核。

The result shows it can identify effectively the face of endosperm . 6 . take two surface pictures of corn seed and research feature parameters of two surfaces and their influence 6 、對一粒玉米種子兩面各拍一幅圖像,研究兩面特征,分析它們之間差異及對品種特征的影響。

Amylographic viscosity measurements , a physical property of milled rice flour , are important eating and processing quality parameters of rice and are characteristics of the endosperm 摘要白米淀粉糊黏度測定值是稻米食用與加工品質非常重要之介量,屬胚乳性狀。

It also showed that the seed building ability was weaker , linear dry matter accumulation ability was stronger and endosperm water losing was earlier 研究還表明,西南山地玉米籽粒發育的特點是籽粒建成能力較弱、干物質線性積累能力很強、胚乳失水成熟早。

The pollen grain germinates on a special extension of the carpel , the stigma , and double fertilization results in a diploid zygote and triploid ( usually ) endosperm nucleus 花粉粒在柱頭上萌發,雙受精導致雙倍體的合子和三倍體的胚乳形成。

Gymnosperms lack endosperm and the precise double fertilization characteristic of the angiosperms , although some show a primitive form of it 盡管裸子植物還保留有某些被子植物的基本形態,但它沒有被子植物所特有的胚乳以及雙受精現象。

Kara belonged to relatively primitive sect . leymus hochst . , with bigger endosperm cells than those of l . multicaulis ( kar 了了js具有較大的胚乳細胞,其長寬比也較大;屬于較進化的seot . anjs勿妙了u厲( griseb . ) tzvel .的多枝賴草乙

In flowering plants the endosperm tissue is usually triploid , resulting from the fusion of one of the pollen nuclei with the two polar nuclei 在開花植物中,胚乳組織多為三倍體,由一個花粉核和兩個極核融合產生。

The characters of endosperm cells may be used to distinguish the species in leymus . l . arenarius ( l . ) hochst . , l . racemosus ( lam . ) 屬于較原始的sect .乙倒助附‘ hochst .的沙生賴草l . a廠e朋月us 、大賴草乙

So , the rank of inducing callus from easy to hard is cotyledon , hypocotyls , stem , leafstalk , radicel , endosperm , leaf and root . 3 誘導的難易分別為:根段、葉片、胚乳、胚根、葉柄、莖段、胚軸、子葉。

In endospermic seeds the endosperm replaces the nucellus and is often a rich source of growth - regulating substances 在有胚乳種子中,胚乳取代珠心,成為生長調節物質(應為營養物質譯者注)的豐富來源。

5 . developing is an algorithm that distinguishes the face of endosperm by the image feature of endosperm 5 、研究并提出了判別玉米種子胚乳部所在面的檢測算法,該算法利用胚乳部所在面的圖像特征。

In nonendospermic seeds most of the endosperm is absorbed by the developing embryo and the food stored in the cotyledons 在無胚乳種子胚的發育過程中,大部分胚乳被吸收,養料儲存在子葉中。

Aleurone layer the outermost proteinrich layer of the endosperm of grass fruits ( e . g . cereal grains ) 糊粉層:在谷類種子胚乳最外面的一層或幾層細胞,含有大量的糊粉粒。
