| 摘 要： | 采用中心组合设计和响应曲面法在实验室条件下研究了Cd2+与Zn2+对马氏珠母贝受精率的影响。Cd2+、Zn2+的浓度范围分别为0.030—20mg/L、0.100—20mg/L。结果表明:Cd2+与Zn2+两因子对马氏珠母贝受精率的一次效应极显著(P<0.01);Cd2+与Zn2+两因子一次互作效应极显著(P<0.01)。经响应曲面法分析,随着Cd2+与Zn2+浓度的增加受精率呈下降趋势,当Zn2+浓度在最低浓度(0.100mg/L)时,受精率随着Cd2+浓度的上升而下降;当Cd2+浓度在最低浓度(0.030mg/L)时,受精率随Zn2+浓度的上升而先下降后升高。本实验建立了马氏珠母贝受精率与Cd2+、Zn2+间关系的模型方程(R2=0.996,Adj.R2=0.987,Pred.R2=0.887,P<0.01)并可用于预测Cd2+、Zn2+对马氏珠母贝受精率的影响。

| Abstract: | Using the central composite face-centered design(CCF) and response surface methodology,the combined effects of Cd2+(0.030—20.000mg/L) and Zn2+(0.100—20.000mg/L) on the fertilization rate in Pinctada martensii were studied under laboratory conditions.The results showed that the effects of two factors Cd2+ and Zn2+ on the fertilization rate in P.martensii were highly significant(P<0.01),and effect of Cd2+ was more significant than that of Zn2+.The interaction between the two factors was also highly significant(P<0.01).Based on the response surface plots,it was found that with the increased concentration of Cd2+ and Zn2+,the fertilization rate was decreased.When Zn2+ concentration was at its lowest level(0.100mg/L),the fertilization rate decreased with the increased Cd2+ concentration.When Cd2+ concentration was at its lowest level(0.030mg/L),the fertilization rate was first decreased and then increased as the concentration of Zn2+ increased.The model equation of the fertilization rate towards Cd2+ and Zn2+ was established,with R 2 = 0.996,Adj.R 2 = 0.987 and Pred.R 2 = 0.887(P<0.01).The model equation could be practically used for forecasting the effects of Cd2+ and Zn2+ on the fertilization rate in P.martensii. |
