使用流式细胞计和染色体制片法 ,对栉孔扇贝同一诱导群体的胚胎、D型初期幼虫和 6～7mm稚贝的三倍体率进行了检测 ,结合制片法对非整倍体现象进行了观察。结果表明 ,胚胎阶段检测出的三倍体率较高 ,D型初期幼虫和稚贝阶段的三倍体率无明显差异。胚胎阶段存在的非整倍体 ,在稚贝阶段未查出 ,尚不能确定存在的可能性 Using flow cytometry and chromosome preparation, the embryos of the same induced group, the initial larvae of D type and the triploidy rate of 6 ~ 7mm juveniles were detected. Combined with the method of production, the aneuploidy phenomenon Observed. The results showed that the rate of triploidy detected in the embryo stage was high, and there was no significant difference in the triploidy rate between the stage D larvae and juvenile. Aneuploidy in the embryo stage is not detected at the juvenile stage and the possibility of its existence is not yet known
