受精核

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。

Part one: Previous results indicated that the abnormal development of haploid goldfish embryos is due to the expression obstruction of some proteins, which are correlative with eyes development, nerve development, development regulation, cell differentiation and maintenance, arthromere formation and signal transduction.

第一部分金鱼雌核发育过程中胚胎蛋白质组比较研究前期已发表的工作表明在金鱼雌核发育眼睛形成期(受精后26个小时)单倍体上一些与眼睛发育、神经发育、发育调控等相关的重要蛋白质未能被选择表达或表达受阻，从而导致单倍体发育畸形。

To induce diploid gynogenesis in summer flounder, eggs were fertilized with heterogenous cryopreservative sperm of Lateolabrax japonicas , which was irradiated with UV ray to be genetically inactivated, and cold shock was used to prevent extrusion of the second polar body.

中文摘要：用冷冻保存的花鲈精子作为异源精子，采用紫外线对精子进行照射使其遗传物质失活，然后与卵子进行"授精"，可以刺激犬齿牙鲆鱼卵进行雌核发育，在受精后一定时间采用冷休克处理"授精"卵，抑制第二极体排出成功获得了犬齿牙鲆雌核发育二倍体鱼苗。

Effects of different fruit-retaining reagents upon fruiting on Yunan seedless wampee;2. To probe into the seedless reason of fruit of the Linyuan 1 seedless wampee ,the Linyuan 1 seedless wampee is observed at its flower organs, pollen quantity and degree of satiation, and germination, and compared with the seed wampee.

为了探讨林院 1号无核黄皮果实无籽的原因，于 1992年～ 2 0 0 0年在广西大学林学院观察林院 1号无核黄皮的花器、花粉数量及饱满程度、花粉萌发情况，并和有核黄皮比较；采用随机区组试验设计，对林院 1号进行自然授粉、去雄不授粉套袋、去雄后用有核黄皮花粉授粉并套袋的授粉试验；观察林院 1号的授粉受精过程。

Following fertilization the emdosperm becomes and remains multinucleate for some time, becoming cellular near the time of pit-hardening

受精以后，胚乳变成多核，并继续存在一个时期，近硬核期时变成细胞状。营火的余烬。

Following fertilization the emdosperm becomes and remains multinucleate for some time, becoming cellular near the time of pit-hardening

受精以后，胚乳变成多核，并继续存在一个时期，近硬核期时变成细胞状。

Most of the a-sexual embryo sacs also parthenogenetically developed into asexual seeds,which is the same as that of their maternal parent.

此外，平邑甜茶也形成次生极核，并在卵分裂前，形成胚乳游离核；而卵的发育，无论受精与否都要经过3-5天休眠后分裂，并逐渐形成小球形胚、子叶胚。

The fertilization was processed by sperm in mature male gametophyte combining with egg cell on the top of archegonia on June 15 or so.

摘要樟子松发育成熟的雄配子体中的精子6月15日左右在颈卵器中上部与卵细胞结合，进行受精作用，其后，受精卵进行游离核分裂，形成8个子核时，开始形成细胞壁。

The aim of this study was designed to explore the possibility oftransferring bovine embryo blastomeres into buffalo nucleated oocytes.

本实验探讨了将体外培养成熟的水牛卵母细胞去核后，作为体外受精生产的黄牛胚胎细胞核移植的受体进行种间核移植的可能性。
