使受精

However, it remains unclear how reliable cleistogamy is for gene flow mitigation: a Co-Extra research project on rapeseed investigating the matter has published preliminary results which cast doubt on the attainment of a high degree of reliability.

然而，目前还不清楚闭花受精对缓解基因流有多可靠。Co-Extra项目以油菜籽为材料研究了这个问题，已经发表了初步结果；这些结果使他们对能否高度可靠地缓解基因流产生了怀疑。

Egg selection enables only the healthiest eggs to be taken from the ovaries for fertilisation. It can be useful for women with diminished number and quality of eggs.

蛋的选择，使只有最健康的卵子将要采取的从卵巢为受精，它可用于妇女与减少的数量和质量的鸡蛋。

On the other hand, if you do get tomate, having bigsexual organs is likely to increase the chance that it will beyoursperm, rather than another male's, that fertilise the female'seggs.

从另一方面说，在交配时，如果一个雄性金龟拥有较大生殖器，那么就意味着这只金龟的精子使卵子受精的几率相对于其它雄性金龟较大。

Weirder still, a woman could conceivably use sperm made from her bone marrow to inseminate her own eggs.

更不可思议的是，一个妇女可以用自己的骨髓培育出的精子使自己的卵子受精。

The only use for males is to inseminate the queen; afterwards they are either driven out of the nest or killed.

雄蚁唯一的作用是使蚁后受精，之后它们就被驱逐出蚁巢或是被杀死。

And some scientists doubt that Nayernia's engineered sperm could ever be functional enough to inseminate an egg successfully.

纳耶尼亚的研究已经使一些伦理学家感到大为惊讶，况且一些科学家怀疑，纳耶尼亚所培育的精子可能会功能有限，难以成功地使卵子受精。

The porine is the polyembryony animal, many obtains the ovocyte from the porine ovary although but the maturity quite to be low; Because the ROSI technology is does not have to grow the mature sole round sperm cell to pour into directly completely in the ovicell nature, jumped over the spermatozoon in to pass through the physiology and the biochemistry, if the ovicell nature mature or the activation degree were insufficient, added the round immature sperm cell maturity quite inferior reason, very possibly Causes the ROSI micro fertilization defeat.

猪是多胎动物，从猪卵巢上获得的卵母细胞数量虽然较多，但成熟度比较低；由于ROSI技术是将没有完全发育成熟的单一圆形精细胞直接注入卵胞质内，跳越了精子在穿过透明带和卵质膜等过程中所发生的生理和生化反应；如果卵胞质成熟或活化程度不够，加之圆形未成熟精细胞成熟度比较差等原因，很可能造成ROSI受精的卵母细胞内部激活因子蓄积减少和生成不足，引起精核解聚困难、精圆核不能形成、第二极体不能排出、卵母细胞孤雌发育率增加等，使ROSI显微受精失败。

After that , the comparison of the fertilizable competences of ICSI and IVF on cryopreservated oocytes was studied in this article , in order to establish an optimized method to improve the fertilizable competences of oocytes up to the level of embryos .

和胞浆内单精子注射两种方法对玻璃化冷冻卵母细胞的受精能力进行了比较研究，旨在建立能够进一步提高牛冷冻卵母细胞受精能力的改进方案，使卵母细胞冷冻技术上升到与胚胎冷冻同样成熟的水平。

When GA_3 was used before flowering at the concentration of 25mg/kg in KYOHO, the seedlessness was due to not being fertilized and when used after flowering in MEI GUI XIANG, the seedlessness was due to the degeneration of fertilized embryo.

巨峰花前25mg·kg~(-1)处理导致胚不能正常受精而形成无籽果实；玫瑰香花后GA_3处理可能使受精胚退化而无籽。

Following chemical activation, blastocysts rate of the treated oocytes was similar to untreated oocytes.8 Following fertilization, however, few oocytes inhibited with CHX developed into morulae/blastocysts, due to a high incidence of polyspermy.9 Cortical granule migration occurred during inhibition, but CHX inhibition impaired CG migration, significantly no oocytes inhibited by CHX completed CG migration after maturation.10 CHX inhibition had no effects onα-microtubles and microfilaments of goat oocytes.

抑制24h转为正常培养24h，不影响卵母细胞的成熟和孤雌激活能力，并且CHX抑制后再成熟的卵母细胞经孤雌激活发育到囊胚的比例与对照组卵母细胞相似。8、体外受精后，CHX抑制后再成熟卵母细胞的多精受精现象显著增加，发育到桑椹胚/囊胚的比例显著低于对照组。9、CHX抑制过程中皮质颗粒仍能发生迁移，但是CHX抑制会对皮质颗粒的迁移造成不可恢复的损伤，使再成熟的卵母细胞内皮质颗粒不能完全迁移。10、CHX抑制对山羊卵母细胞α-微管和微丝都没有影响，无论是抑制后处于生发泡期的卵母细胞，还是抑制后再成熟的卵母细胞，微管和微丝的分布都与对照卵母细胞相似。

It is also known as one of the most poisonous naturally occurring substances.

它也被称为一个最自然发生的有毒物质。

The greatest stress is found at the location on the cross section where V is the largest.

最大应力出现在横截面上V为最大的地方。
