摘　　要：为了探索东北林蛙在越冬期内生殖器官的生理变化,本研究自2013年10月至翌年3月,每月采集雌、雄成体林蛙各10只,测定雄蛙的体重、睾丸重、脂肪体重;雌蛙的体重、输卵管重和卵巢重,并进行测定器官的系数计算和相关性分析。结果表明：雄性林蛙睾丸的重量和系数在越冬期里无显著变化（P〉0.05）,而脂肪体的重量和系数自1月之后显著降低（P〈0.01）。雌性林蛙卵巢的重量和系数自1月开始显著增加（P〈0.01）;而输卵管系数在越冬的第1个阶段（11月~12月间）显著上升（P〈0.01）。相关性分析证明脂肪体是雄蛙的主要越冬能量来源,而输卵管则是卵巢中卵子发育的主要营养物质来源。本研究揭示了林蛙越冬期生殖生理基本规律,并为林蛙养殖提供科学依据。To study the physiological changes of reproductive organs of Rana dybowskii during win- ter dormancy, we collected 10 male and 10 female adult Rana dybowskiievery month from Novem- ber to March. We recorded live body weight, testis weight and weight of body fat of males. We recorded live body weight, ovary weight, and oviduct weight of females. We used correlation a- nalysis to quantify relationships between weights of target organs. Testis weight and testis coeffi- cient were constant during the wintering period（ P 〉 0.05）, while, both body fat weight and coeffi- cient of body fat decreased significantly（ P 〈0. 01 ）after January. Both ovary weight and ovary coeffi- cient of female R. clybowskii increased significantly（ P〈0. 01 ）from January. The oviduct coefficient decreased significantly（ P 〈0. 01 ）during the first phase of wintering（ November to December）.
