胚乳

The development,proliferation and filling of endosperm cell play determined role in the formation of grain weight and quality.

玉米胚乳占籽粒重量的80%以上，胚乳细胞的发育、增殖和充实状况决定着籽粒的重量和品质。

The results suggested that the endosperm haustoria played roles in the absorption and transportation of nutrients to endosperm.

结果表明胚乳吸器起营养物质的吸收和转运作用，向胚乳提供养料。

MEDEA, a master regulator of endosperm development, is known to be imprinted in the endosperm.

其中MEDEA基因是胚乳发育的主要调控基因，在胚乳中被印迹。

At fertilization one male nucleus fuses with the gee nucleus to form the zygote, while the second male nucleus fuses with the primary endosperm nucleus to form a triploid cell, or more rarely a second diploid or a pentaploid cell that later gives rise to the ENDOSPERM.

受精作用发生时，一个精核与卵核融合形成受精卵，第二个精核与最初胚乳核融合，形成三倍体细胞，偶而也形成第二个二倍体或五倍体细胞，三倍体细胞最后发育为胚乳。

The results showed that both starch content of endosperm and fat content of scutellum (except for 0~2 d) decreased. Endosperm starch content of sweet maize was lower than normal corn notably.

结果表明，在种苗转化过程中，两类型玉米胚乳淀粉含量和盾片脂肪含量(除0～2天外)呈下降趋势；甜玉米胚乳淀粉含量显著低于普通玉米。

In angiosperms where the endosperm is commonly in the triploid condition the development of the endosperm generally precedes the development of the zygote.

译：在胚乳通常是 3 倍体的被子植物中，通常胚乳的发育先于合子的发育。

Firstly, it is found that there are many obvious differences between Acorus and Araceae. Their differences are based on many aspects which include characteristics of morphology, anatomy and epidermis of leaf, types of tapetum in anther walls , patterns of endothecial thickenings, and ways of development of endosperms, presence or absence of perisperm, components of photochemistry, and sequences of rbcL.

研究表明：1。菖蒲属与天南星科其它属在叶的形态、结构、表面特征，花药绒毡层类型，药室内壁增厚的特点，胚乳的发育方式，外胚乳的有无，植物化学成分，rbcL基因序列等多方面存在着显著的差异。

This difference enables seeds to be classified as nonendospermic or endospermic.

可以凭借这种结构上的差别将种子分为有胚乳种子和无胚乳种子两类。

In exalbuminous seeds, the endosperm is short-lived.

在无胚乳的种子中，胚乳是短命的。

Seeds erect or pendulous, sometimes winged, usually exalbuminous, very rarely with thin endosperm; cotyledons mostly fleshy and convex abaxially, rarely folded or convolute.

种子直立或者倒生，有时具翅，通常无胚乳，极少有薄的胚乳；子叶几乎肉质并且背面凸，很少折叠或旋卷。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
