| 摘 要： | 采用室内实验生态学方法研究了不同规格和温度对处于标准代谢下三角帆蚌耗氧率的影响。结果表明个体大小、温度以及二者的综合效应均对其耗氧率有极显著的影响(P<0.01);三者的影响程度为个体大小>温度>二者综合效应。个体大小与耗氧率的关系为随着体重的增加,三角帆蚌的耗氧率降低,呈负相关的幂指数关系;体重与耗氧率的方程OR=aW-b,b值均在0.7715～0.9709之间,平均为0.875。温度对三角帆蚌的影响表现为在一定温度范围内,耗氧率随温度的升高而加大,但超过适温上限的临界点则表现出下降趋势,甚至停止呼吸。

| Abstract: | The relationship of the oxygen consumption rate (OCR) of Hyriopsis cummingii with body size and temperature in standard metabolism was studied under controlled laboratory condition in this paper. The results indicate that size of individual, water temperature and both together have significant effects on OCR (P<0.01). Among these effects, effect of body size>that of temperature>the mixed effect. OCR decreases as the increase of body size and there is a negative exponential regressive function OR=aW~(-b),b value of 0.7715-0.9709, With a mean value of (0.875). The experiment indicates OCR rises with the rise of temperature in a temperature range; nevertheless, OCR decreases and even the respiration of Hyriopsis cummingii ceases when exceeding the upper critical point. |
