稀土元素浓度为 2 5mg/L时孵化率最高 ,为 82 90 % ;稀土元素浓度为 1 5mg/L时 ,大银鱼胚胎发育时程最短 ,为 5 80 5 7h ,比对照组缩短 1 80 4 6h。
When the concentration of rare earth element was 25mg / L, the hatching rate was the highest (82 90%). When the concentration of rare earth elements was 15mg / L, the shortest time of embryo development was 57807h, which was shortened by 1 804 6h.
