| 摘 要： | 本文以中国太平洋牡蛎二倍体自交作为对照,比较了诱导三倍体群体及其杂交三倍体的早期表型性状。通过对各试验组卵径、卵裂率、D幼率、D形幼虫大小、生长、存活率和倍性等指标进行测定,进一步评估了2种诱导方法的有效性。结果表明:与诱导三倍体群体相比,杂交三倍体表现出明显优势,D幼率、D形幼虫大小均大于诱导三倍体群体,且差异显著(P<0.05);稚贝期壳长和壳高生长也显著快于诱导三倍体群体(P<0.05)。至附着,杂交三倍体的存活率很高,显著优于诱导三倍体群体。就三倍体率而言,杂交三倍体达到100%,而诱导三倍体群体仅为51.00%±11.79%。由上得知,杂交三倍体更适合应用于大规模生产。

| Abstract: | Performance of induced and hybridized triploid Pacific oysters(Crassostrea gigas) was studied and compared for traits such as fertilization and hatching success,survival,larval and juvenile growth.The results showed that hybridized triploids were superior over induced triploids,and the difference in hatching success and D-larval size was significant(P<0.05).Larval survival of the hybridized triploids was significantly higher than that of induced triploids.Juvenile shell height and shell length of hybridized... |
