【摘要】 以"中科红"海湾扇贝为种贝,研究了在人工促熟条件下其性腺发育各期的特点,分析了积温和性腺指数的函数关系。实验结果表明,性腺发育在生物学零度6.6℃以下时,为休止期;水温14℃,积温171℃,性腺指数8.59,发育到增殖期;水温15℃,积温216℃,性腺指数11.49,为生长期;水温17℃,积温267℃,性腺指数15.85,达到成熟期;水温21℃,积温达446℃,性腺指数达17.99,为排放期,同时也对影响性腺发育的因子等进行了讨论。更多还原

【Abstract】 Argopecten irradians is one of the most important clam species cultured in China.We reseached the histology of its gonad develepment and the relation between periodic variation of histology with gonad development and effective accumulated temperature.The gonads were fixed with Bouin’s solution,and tissue sections were stained with H·E solution.Taking micrography pictures is to show the gonad development.The results showed that: when the biology zero-pointis below 6.6℃,the gonad was at a resting stage;when the water is 14℃,effective accumulated temperature is 171℃,the gonad index was 8.59,the gonad was in a multiplication stage.When water temperature is 15℃ and effective accumulated temperature is 216℃,the gonad index was 11.49,the gonad was at a growing period.When water temperature is 17℃ and effective accumulated temperature is 267℃,the gonad index was 15.85,the gonad was at a matureity period.When water temperature is 21℃ and effective accumulated temperature is 446℃,the gonad index was 17.99,the gonad was at a sprawing period.This paper discussed the influence factor on gonad development of A.irradians.更多还原
