| 摘 要： | 目的]研究中华条颈龟（Mauremys sinensis）胚胎发育过程中外部形态的变化。方法]在恒温（29±0.5）℃,相对湿度为85%～90%,基质湿度为5%～10%的孵化条件下,连续解剖观察了中华条颈龟胚胎发育的过程。对胚胎发育各期主要形态学特征进行了详细描述,并配以周详的图片比较各期的典型特征。结果]中华条颈龟的孵化期为53.00±1.77 d,根据其胚胎的日龄、大小和形态特征的变化将整个的胚胎发育分成了23期,其中9～23期主要以四肢、背甲、腹甲、头部、尾部等的变化为分期依据,同时,对龟鳖类胚胎发育分期的标准进行了讨论。结论]结果有利于龟鳖类胚胎发育分期的标准化。

| Abstract: | Objective] The aim was to observe the morphological changes of embryonic development of M.sinensis.Methods] Embryonic development process of M.sinensis were observed based on serial dissection,under the condition of constant temperature(29±0.5)℃,relative humidity 85%-90%,5%-10% of matrix humidity,and the major morphological characters of every stage were described in detail with amply photos respectively.Results] The incubation period of M.sinensis were 53.00±1.77 d,according to the embryo daily age,size,and morphological characters,the period of embryonic development was divided into twenty-three stages,hereinto,stages 9 to 23 were affirmed mainly by the shape changes of limbs,carapace,plastron,head and tail;meanwhile,staging criteria of embryonic development of chelonia was discussed here.Conclusion] The results were beneficial to the standardization of morphological development of M.sinensis. |
