摘要: 在恒温(29±0.5)℃,相对湿度为80%—93%,沙盘含水量5%—10%的孵化条件下,观察研究了黄喉拟水龟胚胎的发育过程。黄喉拟水龟胚胎孵化周期为67d,根据胚胎日龄、大小及形态特征变化将整个胚胎发育过程划分为22期,其中1—7期以卵黄囊血管区、体节数目、心脏形态变化为主要分期依据;8—22期主要以四肢、背甲、腹甲变化为分期依据。同时在胚胎生长发育过程中对头宽、眼径、背甲长和背甲宽等器官生长数据进行了测量统计,发现头宽、眼径、背甲长、背甲宽与日龄呈显著正相关关系。在胚胎发育过程中观察卵壳外观变化,通过对照各期的胚胎发育状况与卵壳外观变化发现,第1期胚胎时,卵壳中部开始出现白色受精斑;第5—7期时,受精斑绕卵短径一周成环状;第20—21期时受精斑在卵长径的增长停止。
