| 摘 要： | 采用1.95×10-4mol.L-1的KK-42溶液浸润处理南美白对虾(Penaeus vannamei)幼虾(体长为4.2~5.0cm),从组织细胞学水平对分泌蜕皮激素的Y-器官结构进行初步研究,观察KK-42处理后幼虾Y-器官的形态结构变化。结果表明,伴随动物的生长,Y-器官腺细胞条索变粗,腺细胞核增大。KK-42处理后腺细胞核的结构、大小未见显著变化,腺细胞索的宽度明显高于同一时期对照组。

| Abstract: | KK-42 is a kind of juvenile hormone antagonist.The shrimps,Penaeus vannamei(4.2-5.0 cm) were treated by soaking in KK-42 at a concentration of 1.95×10-4 mol·L-1.The structures of Y-organ which secreted molting hormone were preliminary studied by using normal paraffin slice method.The cords of gland cells in Y-organ became wider,and diameter of nucleus increased with development of the shrimp.No significant change was observed in structure or size of gland cells in KK-42 treated group,but the width of cords was higher than that of the control group. |
