Pollen tube prolongs on the surface of axile placenta in locule for 2-4 hours .

传染性腔上囊病原体存在于胚囊和胎座中的淀粉粒为胚胎所利用。

Starch grains present in the embryo sac and placenta are utilized by the embryo .

子房为二心皮一室，多胚珠，侧膜胎座，倒生型胚珠。

The ovary was bicarpellary syncarpous and unilocular having parietal placentas . Ovules were anatropous .

子房2室，中轴胎座。

The ovary is 2 locular .

胎座的胚性细胞经继代培养能保持较长时期的分裂能力。

The embryonic cells of placenta in subculture divi - ded continuously during a longer period .

扁桃果实由单心皮上位子房发育而成，边缘胎座，横生胚珠。

The almond fruit was developed from solitary carpel in the superior ovary which there were the border placenta and amphitropous ovule .

前者的维管束进入子房壁，后者的维管束进入子房的中轴，形成胎座维管束。至延长部后，胎座维管束逐渐消失。

The bundles from the outer region enter the ovary wall , while those from the central region extend into the axile and become placental bundles which fade away gradually in prolongation .

珠柄：被子植物子房中连接胚珠（之后的种子）和胎座的柄。营养物质通过珠柄传递到胚珠和种子。

Funicle ( funiculus ) The stalk attaching the ovule ( later the seed ) to the placenta in angiosperm ovaries . Nutrients pass through the funicle to the ovule and seed .

雌蕊3心皮3室，子房下位，中轴胎座，每室2倒生胚珠，厚珠心，双珠被，内珠被独自形成珠孔。

Its pistil consists of three carpels , the inferior ovary has three locules and each locule has two ovules which are anatropous on axile placenta . The ovule is bitegminous and crassinucellate .

扁桃雌蕊形态结构为：湿型柱头，花柱实心，子房1室，基生胎座，横生胚珠，双珠被，厚珠心，有珠孔塞。

The pistil shape structure of the almond is : Wet column cap , style solid , ovary 1 room , the basal placenta , overflowing-ovule , pairs of integuments , thick nucellus , having obturator .

雄花心皮在发育后期出现特化的组织结构，至雄花开花期时，形成类似雌花胎座的结构，但没有分化出胚珠；

The carpel in male flower at latter developmental stage was differentiated , and a placenta-like structure was formed in the carpel of male flower during anthesis , while ovule did not appear as that of mature female flower ;

在梨形胚到盾片形成期这一发育阶段，靠近胎座处的1～2层细胞呈狭长形或多边形，细胞质浓厚、细胞核小；

During the period from the pear shaped embryo to the formation of scutellum , some slim cells with thick cytoplasm and small nucleus near the 1st and 2nd layers placenta and some particular big endosperm cells could be seen .

单株果数对总产量的直接影响最大，果实胎座宽度及早期产量也对总产量有明显的直接影响，而其它性状则仅对总产量产生有限的直接影响。

Fruit number per plant had the greatest direct effect on total yield , width and early yield had marked direct effect on total yield as well , while other characters had only a limited direct effect on total yield .

雌蕊由5心皮组成，柱头、花柱分离，子房合生，1室，基生胎座，胚珠1个，拳卷型，双珠被，厚珠心，珠孔由内珠被形成。

The pistil was composed of five carpels , stigmas and styli separated , the ovary was coadnate , basal placenta , it had only one circinotropous ovule , the ovule was crassinucellate and had two layers of integument , the micropyle was formed by the inner integument .

雌配子体发育的特点是：倒生胚珠、基底胎座、厚珠心、双珠被、孢原细胞直接长大成大孢子母细胞、反足细胞退化早，胚珠发育为蓼型。

The character of macrospore in development were as followed : anatropal ovule , basal placenta , thick nucellar , two integument , megaspore mother cell coming directly from archesporial cell , early degenerating antipodal cell , thedevelopment of the embryo sac being conformed as the polygonum type .
