In this study, O_2 consumption and CO_2 production rates of young soybean were measured under different temperatures and O_2 concentrations to develop the predicting model for respiration rate under modified atmospheres. A flow through system was developed and used to obtain data. It was observed that the model based on Michaelis-Menten enzymatic kinetics, which had been reported previously, was in good agreement with our experimental data. The model was expanded to describe the Arrhenius type temperature effect on the kinetic constants K_m and V_<max>. The model developed in this study will enable to predict O_2 consumption and CO_2 production rate of young soybean under various temperatures and O_2 concentrations.

本研究测定了不同温度和O_2浓度条件下大豆幼苗的O_2消耗速率和CO_2产生速率，建立了气调条件下大豆幼苗呼吸速率的预测模型。开发了一个流通系统，并用于获取数据。结果表明，基于Michaelis-Menten酶动力学的模型与我们的实验数据吻合得很好。将该模型扩展到描述动力学常数K_m和V_m的Arrhenius型温度效应<max>。本研究建立的模型可用于预测不同温度和O_2浓度下大豆幼苗的O_2消耗和CO_2产生速率。
