摘要
研究气流法测定苹果呼吸强度过程中气体平衡时间、干燥器中出气管深度、CO2收集时间、气体流速对测定结果的影响，确定测定中的具体参数。结果表明：对于贮藏后期红富士苹果，气流法测定呼吸强度时气体平衡时间应为30min，干燥器出气管深度应超过干燥器深度3／4，CO2收集时间应为30min，气体流速控制在400mL/min，在此条件下测定贮藏后期红富士苹果的呼吸强度为32．0mg·kg^-1·h^-1。
The effects of air-balance time, air-outlet pipe depth in desiccator, CO2 gathering time and air velocity on apple respiration intensity were studied in the experiment. The results showed that the optimal parameters were air-balance time 30 min, air-outlet pipe depth higher than 3/4 of the depth of desiccator, CO2 gathering time 30 min, air flow velocity 400 mL/min for Red Fuji apple. The respiration intensity was 32.0 mg·kg^-1·h^-1 under these conditions.
