The optimization of heat shock conditions for producing tetraploidy loach was treated the fertilized eggs for 4 min with 41℃ water after fertilization about 20 minutes.

采用热休克抑制受精卵第一次卵裂、Ag-NOR计数鉴定四倍体胚胎的方法，探索了诱发四倍体泥鳅的最佳条件是：在受精后20 min左右采用41℃热水持续处理泥鳅受精卵4 min。

It indicated that the yield of tetraploidy not more than 25% induced by inhibiting the first mitosis with CB, colchicine and 6-DMAP, respectively, while it can be induced with higher percentage by blocking PB1releasing with CB. The tetraploidy percentage of groups shock began at 15—22min after fertilization are higher than that shock began at 42min, and the yield of tetraploidy also increased with the CB density and time lasting.

结果表明，CB、6-DMAP和秋水仙素抑制扇贝第一次卵裂诱发四倍体的比例低于25%；采用CB抑制PB1可有效地诱导产生四倍体，从授精后42min提前到15—22min开始处理，抑制PB1的放出有助于提高四倍体的比例，在12℃，处理开始和终止时间分别在授精后20—22min和62—67min时(即PB2始出现时)，面盘幼虫四倍体率最高，为56.5%。
