配子体的

One of two sperm get into an archegonium and fused with egg. The nucleus of fertilized egg began to divide, and the walls were formed after the third division. The eggs without fertilization divided two times and then disappeared.

雄配子体产生的两个精子中的一个进入颈卵器与卵细胞结合形成受精卵，受精卵核到第3次分裂形成细胞壁，没有受精的卵细胞还要进行两次有丝分裂后才消失。

In this paper the authors reviewed the characteristics in the different phases in the life cycle of ferns. Special attentions were given to the effect of light, plant growth regulators, water and temperature on the fern gametophyte development, and the effect of antheridiogen, light, calcium and other plant growth regulator on the formation and differentiation of fern sex organ.

作者概述了蕨类植物生活周期中不同发育阶段的特点，并着重介绍了光、植物生长调节物质、水和温度等因素对蕨类植物配子体发育的影响以及成精子囊素、光、钙离子和其它植物生长调节物质在性器官形成和分化过程中的作用。

Light plays very important role in the growth of Gametophyte clone. Light time and intensity affect its growth directly.

光照对海带配子体克隆的生长起着至关重要的作用，光照时间和光照强度直接影响着克隆细胞的生长。

The polar and egg nuclei of the female gametophyte are genetically identical.

雌配子体中的极核和卵核遗传上是同一的。

Usually there were two archegonia in a female gametophyte which developed a synchronously at first, and gradually developed in concert.

一个雌配子体中的颈卵器数目通常为2个，它们的发育最初不同步，以后逐渐趋向一致。

In these groups and in the bryophytes, some species produce unisexual gametophytes and some produce hermaphrodite gametophytes.

这些类群以及苔藓植物中的某些种类的配子体属于雌雄异株，而另外一些则为雌雄同株。

The gametophyte development of the two species were observed morphologically. Spore germination rates and sporophyte appearance rates in various culture media and substrate were also studied.

falcata 的孢子，对其配子体发育过程进行形态学观察，研究不同培养基中孢子的萌发率及成苗情况。

During the fertilization of angiosperms, the degenerated synergid induces a pollen tube to enter and break the pollen tube to release two sperm cells, which fuse with the egg and central cell.

在受精过程中，助细胞吸引花粉管向雌配子体生长，并接受花粉管长入细胞程序死亡助细胞中。接下来的花粉管停止生长和花粉管顶端破裂释放出2个精细胞的过程可能也依赖于助细胞。

Male gametophytic selection is known as a powerful motivation in biological evolution, and is also considered as an important factor that influences genetic differentiation, variation and genetic diversity in plant.

雄配子体选择是影响植物遗传分化、演变和遗传多样性的重要因素，被认为是生物进化的有力动力。

S-RNase-mediated gametophytic self-incompatibility is controlled by a multiallelic S-locus at which two separate genes, the female and male specificity determinants, are tightly linked.

配子体自交不亲和由具有多基因的单一位点S位点控制，该位点包括紧密连锁的雌性和雄性S决定因子。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
