A minute structure in seed plants, containing the embryo sac and surrounded by the nucellus, that develops into a seed after fertilization.

胚珠种子植物的一个小的结构，含有胚囊并被珠心所包围，施肥后长成种子

The ovule of development is the one nucellus that make a group at first organization, because basilar segmentation is rapidder and form or two bags by the layer, bead by , other nucellus the organization laps inside and next alveolus stays in one aspect of the matter, bead aperture .

发育的胚珠最初是一整团珠心组织，由于基部的细胞分裂较快而形成一层或两层包被层—珠被，将其他珠心组织包裹在内并在一端留下一个小孔—珠孔。

Ovary 2-locular, carpels free at apex; ovules mostly 1 per carpel, less often many, but then most of them sterile, crassinucellar, bitegmic, anatropous, halfway between apotropous and epitropous, pendent from ovary top if solitary, along the carpellary margins if numerous; placentation axile.

子房2室，心皮离生在先端；每心皮多数的胚珠1，较少的通常很多，中途在apotropous和胚珠向上转之间，然而他们中大多数不育，crassinucellar，bitegmic，倒生，中轴胎座花柱和柱头2。

Leaves several, lorate or linear, cross section semiterete or terete, solid or fistulose, base usually not narrowed into a petiole; ovules 2 to several per locule; if leaf base narrowed into a petiole or ovules 1 per locule then bulb tunic never distinctl

叶数个，带状或线形，横断面半圆柱形或圆柱状，中空的固体或，基部通常不缩小成为叶柄；胚珠2到数枚每室；如果叶基部狭窄成为叶柄或胚珠1每室那么鳞茎皮从未是distinctl 7

Gynoecium superior, of 1-5 distinct carpels with adaxial-basal style; ovary with (1 or)2(-5) ovules; ovule basal-marginal or marginal; style gynobasic; stigma clavate to capitate.

雌蕊群上位，具有1-5个离生的心皮和正面基生的花柱；子房具(1或)2(-5)胚珠；胚珠生于基部边缘或者边缘；花柱着生子房基部；柱头棍棒状或头状。

As a sexual reproductive organ, ovules have received much attention by botanists. Since the nineteenth century, the morphology, structure, ontogenesis, origin and molecular biology of angiosperm ovules have been studied in detail.

胚珠作为被子植物的有性生殖器官一直为植物学家所关注。19世纪以来，人们从形态结构、发生发育、起源及分子生物学等方面对胚珠进行了大量的研究。

No morphological difference was observed between embryos gained from ovule culture and embryos grown in planta, indicating that the in vitro ovule culture system phenocopies the in planta developmental program of embryogenesis.

体外培养形成的胚珠及胚胎在形态上与自然状态下形成的胚珠及胚胎几乎没有差异。
