荒漠沙蜥精巢组织结构的季节性变化

本文以组织学方法对荒漠沙出（Ｐｈｒｙｎｏｃｅｐｈａｌｕｓｐｒｚｅｗａｌｓｋｉｉ）精巢的组织结构进行了研究，结果表明，荒漠沙晰精巢的组织结构具有明显的季节性变化。每年４月初出蛰时精巢已相当发育，５月其生精上皮的厚度和曲细精管的直径达全年最高值，６月逐渐减小，７月降至最低值，８月开始回升，１０月中旬入蛰时已接近４月出蛰时的水平。精巢的体积和重量有相同的变化规律。荒漠沙蜥精巢组织结构的季节性变化受光照的影响，光通过作用于松果腺和脑垂体间接地调控其生长发育。

SEASONAL CHANGES IN TESTICULAR HISTOLOGY OF THE PHRYNOCEPHALUS PRZEWALSKII

he Testicular mioroanatomy and its seasonal changes of P.Przewalskii were studied. Itwas shown that the reproduction of P.Przewalskii occuried from spring to summer every y6ar,displaying significant seasonal circle. In Aprie, when adult males concluded hibernation theertestes fairly developed.The seminiferous epithelial height and seminiferous tubule diameter oftestes reached a peak in Mad. Both the height and the diameter decreased in June. In July theheight and diameter were down to minimum. But the weight and diameter of testes graduallyrised in August. In mid-October before Lizards began to hibernate their testes were for to forof in April.Ecological factor that effect on seasonal changes in testicular histlolgy of the lhard illumination time.The illumination controlled the growth and development Of the find effecting on pineal gland and pituitary gland.
