【摘要】 研究了柠檬酸稀土对青虾Macrobrachiumnipponense卵子孵化的影响,结果表明:当柠檬酸稀土的浓度为0.1～0.6mg/L时,孵化率无显著差异;当柠檬酸稀土的浓度为1.2～4.8mg/L,孵化率比对照组高10.6%～26.2%,当柠檬酸稀土的浓度大于9.6mg/L后,孵化率显著降低。卵子对柠檬酸稀土的饱和吸收量为7.95μg/粒。更多还原

【Abstract】 The effect of rare earth citric on egg hatching of Macrobrachium nipponense was studied. When the concentration of rare earth citric is between 0.1 mg/L and 0.6 mg/L,the hatching rates are not influenced (P>0.05). The optimum concentration of rare earth citric are between 1.2 mg/L and 4.8 mg/L. Compared with the control group, it can increase the hatching rates by 10.6 %～26.2 %.The hatching rates increased by absorbing rare earth citric.更多还原
