盘形囊胚的

After Cryopreservation of embryo and larvae of manina clam Ruditapes variegata, the results indicate the survival rate of blastula embryo and vlegier are significantly better than that of trochophore and D-shaped larvae(P.05); the survival rate of blastula embryo is 42.3%(4.0M DMSO) and the effect of high sucrose density is better than that of low sucrose density with the same DMSO dendity.

对杂色蛤胚胎和幼虫的超低温冷冻保存发现，杂色蛤囊胚和面盘幼虫的保存复活率显著高于担轮幼虫和D形幼虫的复活率(P＜0.05)；杂色蛤囊胚的解冻复活率达42.3％(4.0M DMSO)，相同DMSO浓度条件下，高蔗糖浓度组保存效果好于低蔗糖浓度组，但差异不显著(P＞0.05)；在相同蔗糖浓度条件下，抗冻液中DMSO浓度较高组的保存效果好于DMSO浓度较低的组，但差异不显著(P＞0.05)。
