摘要
本文对中国林蛙卵、胚胎、蝌蚪、幼体和成体等不同发育阶段的热生物学研究进行了综述。温度对中国林蛙不同发育阶段均有不同的影响。11~13℃是卵孵化的最适温度,卵孵化率接近100%,胚胎在7~22℃温度范围内均能正常发育;10~20℃是蝌蚪的最佳生长发育温度,成活率都在95%以上;5℃以下蝌蚪不能完成变态;在15~30℃之间,温度越高,雄性比例越大;15~25℃是成体生活的最适温度。这些研究结果可为中国林蛙的人工养殖提供科学依据。
Thermal biology research of Rana chensinensis in the different developmental stages (egg, embryo, tadpole, froglet and adult) was carried on the summary. Temperature had the different influence to Rana chensinensis in the different developmental stages. 11~13℃ is the optimum temperature which the egg hatches, the hatching rate of egg approaches 100%. The embryo can normally develop in 7~22℃ temperature ranges. 10-20℃ is the best development temperature of the tadpole, the survival rate all in 95% above. The tadpole under 5℃ cannot complete the metamorphosis. From 15 to 30℃, the temperature is higher, the proportion of male is bigger. 15-25℃ is the optimum temperature of the adult. These results of research may forthe artificial cultivation of Rana chensinensis provide the scientific basis.
