摘要

本文报道了对湖蛙早期胚胎发育的初步观察。湖蛙早期胚胎发育分25个期

在28±1℃条件下

整个发育过程需176.4h

与其他无尾两栖类比较

湖蛙发育速度缓慢;具明显的孵化期

胚体伸长较早;在鳃盖形成中

外鳃出现脱落现象.

Abstract

This paper deals with the study of thc early embryonic development of Ranaridibund.It includes the ivision of stages

a normal table of devetopment at28±1℃

description and photographs of the external forms.The whole course ofthe embryogenesis is divided into 25 stages according to the morphological cha-racteristics of the embryos.This is similar to the eases of other anurans.As aspecies

R.ridibund(?) has its own features:1.Among Chinese species

R.ridibund(?) is one of the slowest anurans in therate of embryonic development.It takes 176.4 hrs to complete whole process at28±1℃.2.After muscular response

R.ridibund(?) undergoes a long and obvious hatch-ing stage.3.The elongation of the embryo along the longitudinal axis occurs at neuralplate stage.4.The shedding of external gills can be observed during the formation of theopercula.
