摘　　要：通过测定石榴果粒在不同温度下休眠期内呼吸强度的变化,建立经验模型,化学动力学模型,Langmuir模型以及非竞争型、竞争型和反竞争型的酶动力学模型等6种呼吸速率模型。基于气调休眠保鲜的基本理论,将果蔬呼吸过程分为诱导期、休眠期和衰亡期3个阶段,并通过监测贮藏环境中氧气和二氧化碳气体含量的变化,计算出果蔬休眠期起始和终止时间点。结果表明:石榴果粒呼吸强度随温度的升高而增大,在4℃贮藏条件下竞争型酶动力学模型方程相关系数最大,对该模型进行验证,实测值与预测值之间的相对误差在1.19%~5.45%之间,t检验结果显示实测值同预测值之间无显著性差异。In this study,six different types of respiration rate models,including the empirical model,chemical kinetic model,Langmuir model,and non-competitive,competitive,and anti-competitive enzyme kinetic models,were developed by monitoring the variation in the intensity of pomegranate fruit respiration throughout the dormant phase at various temperatures.Based on the basic theory of controlled atmosphere dormancy preservation,the respiration process of fruits and vegetables was divided into three stages:induction,dormancy and decay.The beginning and conclusion of the dormant period were determined by measuring changes in the oxygen and carbon dioxide gas contents in the storage environment.The results showed that the respiration intensity of pomegranate grains increased with the increase in temperature,and the correlation coefficient of the competitive enzyme kinetic model equation was the largest under the storage condition of 4℃.The relative error between the measured value and the predicted value was 1.19%-5.45%,and the t-test results showed no significant difference between the measured value and the predicted value.
