We investigated the sensitivity of resting eggs of the cladoceran Moina macrocopa to the effect of ionizing radiation during the reactivation of the eggs. The study showed that the resting eggs during reactivation are more vulnerable to irradiation than the resting eggs in a stage of deep dormancy. The decrease in the efficiency of egg reactivation was observed at high doses, the growth rate of juveniles, fecundity, and the number of produced clutches by females strongly decreased when resting eggs at the reactivation stage absorbed doses of 64 Gy and higher.
我们研究了枝角类大型溞的滞育卵在活化过程中对电离辐射影响的敏感性。研究表明，活化过程中的滞育卵比深度休眠阶段的滞育卵更容易受到辐射影响。在高剂量下观察到卵活化效率降低，当处于活化阶段的滞育卵吸收64 Gy及更高剂量时，幼体的生长速率、繁殖力以及雌性产生的卵块数量均大幅下降。
