Egg hatchability was affected significantly by irradiation but there was no significant difference in eggs laid per female, fecundation eggs as increasing treated doses. 受精卵的孵化率受辐照剂量的影响显著,但每雌产卵量、受精卵数对辐照剂量的增加反应不显著。

SONG DANDAN: LOVE AGAIN The effect of treatment with hormones after fecundation is best to pollination. 先授粉再进行激素处理,受精效果较好。
Therefore, the pollination and fecundation was bad, a lot of fruit dropped, the rate of fruit set was low, the growth of young fruit was restricted, and the speed of fruit growth slowed down, and finally the yield decreased. 因而致使授粉受精不良,落果严重、座果率低,同时幼果生长受抑制,果实生长速率减慢,最终造成产量降低。
At last, we noted the age to producing first egg in each group, laying rate, egg weigh, fecundation rate, produced qualified egg counts in each group on every week. 记录并统计各处理组鸡群的开产日龄、每周产蛋率、蛋重、受精率和合格率。
