摘要
贵州疣螈（Tylototritonkweichowensis）是一年繁殖一次的有尾两栖动物。繁殖期肥满度、肝脏系数、脂肪系数、性腺成熟系数、性腺体积均具一定的生物学意义。繁殖期一般为5月上旬至7月上旬，窝卵数平均121．5±7．81枚，孵化期21．6天，孵化率44．33％。每窝印数与雌体头体长成正相关。幼体不同日龄的形态特征变化明显。其全长的Logistic生长方程为：
The Guizhou newt, Tylototriton kweichowensis Fang and Chang, deposits once a year. The fattiness during reproductive period, coefficient of liver, coefficient of far, coefficient of mature gonad, and volume of the latter have certain biological significance. In gereral, the breeding season begins from the first ten-days of May till early of July. One clutch contains 121.5± 7.81 eggs. Hatching period takes 21.6 days. Rate of hatch is 44.33%.There is a positive interrelationship between the size of clutch and the snout-vent length of the female. The change of morphological features of the young distinctly different day by day. The growth logistic eqiation is:Total legnth =
