从三倍体率、D幼孵化率、幼虫生长速度、生产成本等方面比较了细胞松驰素 B、二甲基氨基嘌呤、咖啡因三种化学诱导剂诱导太平洋牡蛎产生三倍体的效果。 CB的三倍诱导率最高 ,为91.5% ,但 D幼孵化率最低 ,仅为 5.8% ,且成本最高 ,为 6 - DMAP和咖啡因的 4倍和 50倍。 6 -DMAP的三倍体诱导率略低于 CB,为 88.0 % ,但 D幼孵化率最高 ,为 6 0 .5% ,其成本仅为 CB的1/ 4。咖啡因的三倍体诱导率最低 ,为 82 .4 % ,幼虫孵化率为 30 .2 % ,但其成本最低 ,仅为 CB的 2 %和 6 - DMAP的 8%。三种诱导剂诱导的三倍体群幼虫在生长速度及成活率方面无显著差别。
The effects of cytochalasin B, dimethylaminopurine and caffeine on inducing triploidy production in Pacific oyster were compared from the aspects of triploid rate, D juvenile hatching rate, larval growth rate and production cost. CB induced the highest triple induction rate of 91.5%. However, the rate of juvenile incubation was the lowest at 5.8% with the highest cost of 4 - and 50 - fold increase for 6 - DMAP and caffeine. The triploid induction rate of 6-DMAP was slightly lower than that of CB, 88.0%. However, the highest rate of juvenile D incubation was 6.5%, which cost only 1/4 of that of CB. Caffeine had the lowest triploid induction rate of 82.4% and larvae hatching rate of 30.2%, but the lowest cost was only 2% of CB and 8% of 6 - DMAP. Three kinds of inducer induced triploid group larvae in the growth rate and survival rate no significant difference.
