研究了 4种不同激素 (17α -羟孕酮、 5-羟色胺、前列腺素和保幼激素 -Ⅲ )的体外注射对中国对虾 (Penaeuschinensis)卵巢发育的作用效果 .试验结果显示 :用 10 0ng/g浓度的 17α 羟孕酮和 5 羟色胺注射亲虾对对虾卵巢的发育有明显的刺激作用 ,生殖指数分别比对照组增加了 50 0 %和 4 4 7% .而同样浓度的前列腺素和JH Ⅲ的体外注射作用不明显 .在相同条件下 ,去眼柄对对虾卵巢的发育作用最明显 ,生殖指数比对照组增加了 150 % .文中还讨论分析了几种激素的属性和对虾卵巢发育的作用机理 .
The effect of in vitro injection of four different hormones (17α-hydroxyprogesterone, 5-hydroxytryptamine, prostaglandin and juvenile hormone-Ⅲ) on ovarian development of Penaeus chinensis was studied.The results showed that with 10 0 ng / g Concentrations of 17α-hydroxyprogesterone and 5-HT injected broodstock significantly stimulated the development of ovary in shrimp, with a reproductive index of 50% and 44.7% higher than that of the control group respectively. However, the same concentrations of prostaglandins and JH Ⅲ In vitro injection was not obvious.Under the same conditions, to the development of the shrimp ovary the most obvious effect, reproductive index increased 150% than the control group.This paper also discusses the analysis of the properties of several hormones and shrimp ovary development mechanism of action .
