摘　　要：量热呼吸法(Calorespirometry)是从热力学角度来研究植物的生理代谢过程的1种方法。它通过测量代谢热速率和呼吸速率计算出能量利用效率和合成代谢速率或生长速率。本文以沙地柏的量热测定为例详细描述了量热呼吸法的实验过程及其数据分析的方法,阐述了关于植物呼吸和生长的热力学模型机理。它已应用于测量植物的实际生长效率,研究植物生长和环境胁迫的关系以及呼吸和生长对环境温度适应性,从而可应用于作物的选育及引种植物种选择等。Calorespirometry is a method from the angle of thermodynamics to study the process of plant physiological metabolism.Efficiency of energy use and anabolic rates or growth rates can be calculated by measurement of metabolic heat and CO2 rates.Calorespirometric and data-analysis method has been described detailedly by taking the calorimetry of Sabina vulgaris Ant.for example,and the thermodynamics model concerning plant respiration and growth has been explained.Calorespirometry has been used to measure the actual growth efficiency of plant,RAPidly investigate the relationship between plant growth and environmental stresses,and acclimation of plant growth and metabolism to different environment condition,thus can be used for selection of crop plants and plant species for introduction.
