中国林蛙雌化技术研究

Studies on feminizing techniques of Rana temporaria chensinensis

采用物理、生化等技术措施 ,在中国林蛙卵发育的适当时期进行处理 ,能明显提高雌蛙的比例。试验结果表明 :用激素处理 ,雌蛙比例达到 73.3%～ 85.9% ,用化学离子处理可使雌蛙达到83.3%～ 91.6 % ,适宜的低温亦可使雌蛙比例有所提高。处理蛙卵的最适时期应控制在胚胎发育的 17～ 2

The proportion of female frog was increased remarkably when eggs of Rana temporaria chensinensis were treated by physical and biochemical and other technical measures during the suitable development stage. The results indicated that:the proportion of female frog might reach 73.3%～85.9% if treated by hormone and 83.3%～91.6% if treated by chemical ions,respectively;the proportion of female frog might be promoted under suitable low temperature.The optimum time of eggs treatment should be confined from 17th to 25th during embryo development.
