摘　　要：家蚕转青卵冷藏抑制胚胎发育在生产上具有实用价值。为了探讨转青卵适宜的冷藏抑制处理时间,以家蚕品种“湘晖”为材料开展试验。试验于2022年、2023年分2个批次完成,设置5个不同冷藏抑制天数的试验组及对照组(不抑制),蚕卵孵化后调查一日孵化率,并对一日孵化率进行平方根反正弦转换得到的新转换值做方差分析。结果表明,对照组蚕卵的一日孵化率最高,而5个冷藏抑制组随着冷藏抑制时间的增加,一日孵化率呈逐渐下降趋势;2个批次的一日孵化率转换值均值有极显著差异(α=0.05,P<0.01);进一步做两两比较,2022年(第1批次)的一日孵化率转换值对照组与4个抑制组(冷藏抑制2~8 d)间无显著差异(P>0.05),而2023年(第2批次)的对照组与5个抑制组间的差异极显著(P<0.01),具有统计学意义。以上结果提示,“湘晖”2个批次试验蚕卵不同冷藏抑制时间处理组的一日孵化率均值不全对应相同,推测可能还存在其他因素与冷藏抑制因素一起共同影响了“湘晖”转青卵的一日孵化率。从生产效益考虑,建议家蚕品种“湘晖”非必要则不将转青卵做冷藏抑制处理,如若一定要进行转青卵的冷藏抑制,处理时间应控制在1周内为宜。Refrigerated inhibition of turned blue eggs has practical value in production.The refrigerated inhibition test of turned blue eggs was carried out with silkworm variety“Xianghui”to explore the days of inhibition.The experiment was completed in two batches in 2022 and 2023,with a control(no inhibition)and 5 treatments with different inhibited days.We had investigated the one-day hatching rates after the incubation of the silkworm eggs,obtained new conversion values after the square root arcsine conversion of the one-day hatching rates and conducted ANOVA using the conversion values.The results showed that the one-day hatching rate was the highest in Xianghui control group,and had a gradual downward trend with the increase of inhibited days.The mean conversion values of the two batches were significantly different(α=0.05,P<0.01),but further pairwise comparison of conversion values showed no significant difference(α=0.05,P>0.05)between the control group and the first 4 inhibited groups in 2022(the first batch),while the control group was significantly different(α=0.05,P<0.01)from all 5 inhibited groups in 2023(the second batch),which had statistical significance.This indicates that in silkworm variety“Xianghui”,the mean values of the one-day hatching rates of the two batches with different treatments not all correspond to the same,and there may be other factors that together with refrigerated inhibition factor affect the one-day hatchability of the turned blue eggs in“Xianghui”.Considering the practical value of one-day hatchability,it is necessary to carefully consider that whether or not there is an urgent need for the cold storage treatment of Xianghui’s turned blue eggs.And better to refrigerate the eggs within one week if there are no other choices.
