| 摘 要： | 荒漠沙蜥（Ｐｈｒｙｎｏｃｅｐｈａｌｕｓｐｒｚｅｗａｌｓｋｉｉ）１年繁殖１次，有明显的季节性周期。４月初出蛰时雄性精巢已相当发育，５月其重量和体积最大，６月变小，进入精子发生的晚期，７月降到最小，８月开始回升，１０月中旬入蛰时已接近春季出蛰时水平。１年内仅７月精巢中无精子。雌性出蛰后卵细胞开始发育，４月下旬进入成熟期，６月达高峰，７月下降，８月进入休止期。每雌年产卵１～３枚或１～４枚，平均１．８３（ｎ＝４８，１９８７）和２．１７（ｎ＝４８，１９９３）。特定体长组的生殖率是影响种群年平均生殖率的主要因素。生殖周期与光周期相符，光周期是影响荒漠沙蜥生殖周期的主要气候因子。

| Abstract: | The reproductive ecology of Phrynocephalus przewalskii was studied in Shapotou of Ningxia. Male and female P. przewalskii were examined monthly in 1987 and 1993. Seasonal changes in the histological morphology of the testes and developments in ovum cells were observed. The reproduction of P.przewalskii occurs from spring to summer every year, showing significant seasonal circle.When adult males concluded hibernation their testes have fairly developed. The weight and the volume of the tests were upto greates... |
