Under light microscope, the egg is an oblated and agglutinated demersal with a narrow perivitelline space; eggs ranged in diameter from 1.95 to 2.38 mm with a mean of 2.18 ± 0.03 mm; their membrane are smooth and they have 5 to 7 cannular keratose egg-filaments; the oil globules are multiple, ranged in diameter from 0.05 to 0.50 mm and in number from 7 to 145 with a mean of 28±2, the position of them migrate during embryonic development; the yolks are ivory-white with no segments, ranged in diameter from 1.00 to 2.30 mm with a mean of 1.90 ± 0.03 mm; the development phases of the embryo are variable. So they were identified as the eggs of one Beloniformes.

在光学显微镜下：卵呈微扁圆形，卵径1.95~2.38mm，粘着沉性；卵黄间隙较窄，卵黄囊呈乳白色，无龟裂；卵膜平滑，在其表面有5~7根细长角质管状卵膜丝；多油球数不定（4~145），油球径0.05~0.50mm，油球在卵黄囊中的位置随不同的发育时期而不断发生变化；胚体处在不同的发育阶段，其特征符合颌针鱼目鱼卵的特征。

在体外比色法观察大豆胚轴提取物对大鼠小肠黏膜蔗糖酶和麦芽糖酶活性的影响，并用快速过滤法观察其对兔小肠刷状缘囊泡葡萄糖转运活性的影响。

During the development three outstandingcharacteristics were observed:three kinds of different division taking place;.the orientation of spindle to be fixed in the three mitosis of one-nucleate embryo sac;.changes of starch grains during megagametophyte development to be regularity.

单核胚囊三次有丝分裂纺锤体的定向较为固定。

The megaspore tetrad is linear. The chalazal megaspore develops into an embryo sac of the polygonum type.

大孢子四分体线形排列，合点端大孢子为功能大孢子，胚囊发育为蓼型。

Mature embryo sac can form from megaspore mother cell on the modified VW medium supplemented with 0.5mg/L BA and 0.1 mg/L NAA.

在培养基无外源激素或仅含生长素或细胞分裂素时，雌配子体的发生过程不能顺利完成；在改良VW培养基上添加0.5 mg/L BA和0.1 mg/LNAA时，形成成熟胚囊。

The megaspore mother cell is located at the 3rd or 4th layer of cells in the nucellus top end. It divides transversally to form a linear megaspore tetrad, and the megaspore at the chalazal end develops into the embryo sac mother cell.

大孢子母细胞位在珠心顶表皮下第三或四层细胞处，经横分裂后产生一直线形的大孢子四分体，其中位居合点端的大孢子发育成胚囊母细胞。

In first stage,from the beginning of pollination to megaspore tetrad,pollen tubes grow axially,passing through gynostemium to the ovary and from proximal placenta along ovary wall develop upward.

花粉在柱头上萌发和生长后，花粉管沿着花柱一直延伸到子房，进入胚囊释放精细胞，实现精卵结合，这就是亲和受精过程[1]。

Inner cell mass were separated by micromanipulator with laser micro-dissection under the microscopy.

在显微镜下利用显微操作仪及胚胎专用雷射将胚囊之内细胞质分离。

The thesis work is to investigate the connection of [Ca2+]cyt and fertilization by avoiding drawbacks noted above, say, employing an ideal experimental plant, Torenia fournieri , with a naked embryo sac that protrudes from the micropyle.

因此，材料本身的结构限制和研究手段的限制使得植物双受精过程中胚囊内胞质游离钙的研究相比之下显得落后。
