| 摘 要： | 对Ca2 和K 诱导西施舌(Coelomactra antiquata)幼虫附着变态的效果进行了研究.结果表明:Ca2 添加浓度为20 mmol/L时诱导效果较为理想,变态率、附着率分别为42.8%、86.1%;K 添加浓度为10 mmol/L时,幼虫变态率、附着率分别为33.5%、83.7%.Ca2 诱导西施舌幼虫附着变态的效果优于K . |
| 关 键 词： | 西施舌 附着变态 诱导 Ca2 K |

| Abstract: | The settlement and metamorphosis of the larval of Coelomactra antiquata treated with Ca2 and K .The results indicated that the hightest settlement and metamorphosis rates of was carried out.Component larval were observered in Ca2 concentration of 20 mmol/L,the settlement rate was 86.1% and the metamorphosis rate was 42.8%.The hightest settlement and metamorphosis rates of component larval were observered in K concentrations of 10 mmol/L,the settlement rate was 83.7%,the metamorphosis rate was 33.5%.Ca2 can induce the larval settlement and metamorphosis of Coelomactra antiquata more effectively than K . |
| Keywords: | Coelomactra antiquata settlement metamorphosis Ca2 K |
