| 摘 要： | 采用骨龄学方法，对半人工养殖的120只东北林蛙（Ranadybowskii）进行年龄鉴定，将样本分为6个年龄组（2～7龄），并在此基础上研究了林蛙的性成熟年龄、生长速率及性别二型性等。结果表明：林蛙性成熟年龄为3岁；雌蛙平均体长（64．79±8．41）mm显著大于雄蛙平均体长（60．83±4．46）mm（P〈0．05）...

| Abstract: | In this research, the age, growth rate and sexual dimorphism in population of the Dybowski＇s frog （ Rana dybowskii） from half ratified farm were studied in 2010. The result showed that age of frog ranged from 2 - 7 years among 120 individuals. Endosteal resorption might have eroded away the first LAG in only 12.50% of the samples, maturity age was 3 years old. The mean Sount-Vent Length was （60.83± 4.46） mm in males and （64.79 ± 8.41 ） mm in females, the mean body mass was （19.81 ± 4.46） g in males and （27.75 ± 10.02） g in females, the mean length and body mass of females frogs were significant higher than those of males （ P 〈 0.05 ）, the mean phalanx diameter was （476.78 ± 61.73） μm in females and （473.79 ± 62.63） μm in males, but on significant. The growth coefficient （k） was 0.567 in males and 0.429 in females. |
