摘要
分别用细胞松驰素B（C．B）（浓度为0．5mg／L）和低温（10℃）处理诱导华贵栉孔扇贝Chlamysnobilis产生三倍体．抑制第一极体的三倍体诱导率达到44．1％和31．8％；而抑制第二极体的三倍体诱导率分别为90．2％和72．7％（胚胎初期检查）．随着C．B浓度的增加，孵化率下降；而随着温度的降低和休克时间的延长，非整倍体增多．
Triploid induction by application of cytochalasin B (C. B) and cold shocks during early development soon after fertilization was attempted in Chlamys nobilis. When the experimental group was treated with 0. 5mg/L C.B, or cold shock at 10℃, the incidence of triploid was 44. 1 % and 31 .8% for the retention of the first polar body, and 90.2 % and 72. 7% for the retention of the second polar body respectively.
