研究了铈 (Ce3 +)对日本沼虾 (Macrobrachiumnipponenese)卵子孵化的影响 .结果表明 ,当Ce3 +的浓度为 0 2mg·L-1时 ,孵化率与对照组无显著差异 ;Ce3 +的浓度范围为 1 2～ 2 .4mg·L-1,可提高孵化率 13 7%～ 19 1% .铈对卵子孵化的促进作用是通过卵子对铈的吸收实现的
The effect of Ce3 + on the egg hatching of Macrobrachium nipponenese was studied.The results showed that there was no significant difference between the hatching rate of Ce3 + and the control when the concentration of Ce3 + was 0 2 mg · L-1. The concentration range of Ce3 + 1 ~ 2. 4mg · L-1, can increase the hatching rate of 13 7% ~ 19 1%. The promoting effect of cerium on egg hatching is through the egg’s absorption of cerium
