The induction ratio of female tetraploid silkworm was dependent on the difference of hybridized combination eggs which were at the period of first maturation division, the more first maturation division eggs, the higher induction ratio. 不同杂交组合材料盛产卵后不同时间卵所处的分裂期不同,影响到四倍体雌蚕的诱发率,处于第一分裂期的卵数越多,诱发率越高;
The egg was activated as the sperm penetrating into the egg, with the development of the second maturation division and the cortex reaction. 精子入卵后,卵子被激动,第二次成熟分裂继续进行,同时发生皮层反应;
Analysis of Fertilizability of Bovine Oocytes Cryopreservation after in Vitro Maturation and Their Chromosomes at the First Cleavage Division 超低温冷冻保存牛成熟卵子的体外受精能力和染色体异常分析
In the secondary maturation cell division the secondary spermatocyte generated spermatid containing 32 nuclei with round, spindle and crescent shapes, which eventually developed into 32 spermatozoon. 第二次成熟分裂由次级精母细胞产生精细胞,有核32个,呈圆形、梭形和弯梭形,由后者发育为32个精子。
The decline in GSH content and increase in ASC content during fruit maturation suggest that GSH is important for cell division during the formation of cucumber fruits, whereas ASC is critical for cell expansion during their development and senescence. 黄瓜果实成熟过程中GSH含量下降和ASC含量升高说明GSH是促使黄瓜果实形成过程中细胞分裂的重要因素,而ASC则促进后期果实发育过程中细胞膨大。
The maturation of DWDM ( Dense Wavelength Division Multiplexing) has greatly improved the capacity of optical communication system and become the mainly technology to increase the capacity of optical transmission network. 密集波分复用(DWDM)技术的成熟极大的提高了光纤通信系统的容量,成为光纤传输网络增容的主要技术手段。
