为探讨温度对白腰朱顶雀（ Carduelis flammea）生理生化指标的影响，以白腰朱顶雀为研究对象，将其分为低温组（5℃）、高温组（30℃）和对照组（23℃）进行驯化，驯化后测定其体质量、体脂质量分数（索氏抽提法）、器官的鲜质量和干质量（烘干恒质量法）、基础代谢率和脱支酶活性。结果表明：低温组体质量降低，在驯化0～2周内下降最为明显，第2周结束时与对照组差异极显著（ p＜0．01）；高温组体质量增高，在驯化1～3周内涨幅较大，第1周结束时与对照组差异显著（p＜0．05）。低温组基础代谢率显著高于高温组（p＜0．05）。3组动物肌肉中脱支酶活性差异不显著（ p＞0．05）；低温组肝脏中脱支酶活性与对照组差异极显著（ p＜0．01），高温组肝脏中脱支酶活性与对照组差异不显著（p＞0．05），低温组肝脏中脱支酶活性与高温组差异极显著（p＜0．01）。可见，温度是影响白腰朱顶雀产热特征改变的主要环境因子之一。低温条件下，白腰朱顶雀通过降低体质量、提高基础代谢率、增加摄入能来补偿能量消耗等一系列的生理生化反应，以适应外界环境温度的变化。

In order to study the effect of the temperature on physiological and biochemical indexes of Carduelis flammea, the ex-perimental animals were randomly divided into low-temperature group ( 5℃) , high-temperature group ( 35℃) and the control group ( 23℃) , and after the domestication , the body weight , the body fat ( by soxhlet extraction method ) , the fresh weight, dry weight (drying constant weight method ) of organs, basal metabolic rate and debranching enzyme activity were determined.The low-temperature group weight reduced , and during the domestication within 0-2 weeks, it was de-clined significantly with extremely significant difference at the end of second week compared with control group ( p<0.01) . The high-temperature group weight increased ,during the domestication within 1-3 weeks, it was increased significantly with extremely significant difference at the end of first week compared with control group ( p<0.05) .Low-temperature group basal metabolic rate was significantly higher than that in high-temperature group ( p<0.05) .Three groups of animal muscle debranching enzyme activity was not significantly different ( p>0.05) .Low-temperature group debranching enzyme activity in the liver was significantly different compared with the control group ( p<0.01) , but for the difference between high-tem-perature group debranching enzyme activity in the liver compared with the control group , there was no significant difference (p>0.05).The difference between the low-temperature group debranching enzyme activity in the liver that in high-tempera-ture group was significant (p<0.01).Therefore, temperature is one of the major environmental factors affecting C.flammea thermogenesis .Under low temperature , C.flammea can reduce body weight , improve the metabolic rate , and increase en-ergy intake to compensate the energy consumption to adapt the temperature changes of external environment .
