abstract
‘malindi’ banana (musa,‘dwarf cavendish’) was stored at three storage conditions (11–12?c and 95.5% rh; 20–22?c and 82–85% rh; and cyclic cooling and warming to simulate day/night conditions during the banana harvest season: 28?c and 50% rh/18?c and 70% rh). fruit storage life was 21, 10, and 8 days in the refrigerated storage, normal room storage, and storage under cyclic day/night conditions, respectively. fruit ripening, respiration, and ethyelene production were significantly higher at high temperature storage and cyclic day/night conditions leading to faster fruit deterioration. under these storage conditions, the rate of fruit weight loss, firmness, vitamin c loss, and chlorophyll degradation was also higher compared to refrigeration.
“malindi”香蕉(musa,‘dwarf cavendish)在三种储存条件下储存(11–12℃和95.5%rh；20–22℃和82–85%rh；循环冷却和加热以模拟香蕉收获季节的白天/夜间条件：28℃和50%rh/18℃和70%rh)。冷藏贮藏、正常贮藏和循环昼夜贮藏的果实贮藏寿命分别为21天、10天和8天。在高温贮藏和昼夜循环条件下，果实成熟、呼吸和乙烯产量显著提高，导致果实变质更快。在这些贮藏条件下，果实的失重率、硬度、*损失和叶绿素降解率均高于冷藏条件。

respiration and ethylene production
respiration rate of the individual banana fruit was measured using a co2/o2 dual gas analyzer (ica15, international controlled atmosphere (ica) ltd., kent, uk). fruit ethylene (c2h4) production rate was measured using ethylene analyzer (ica56, international controlled atmosphere (ica) ltd.). the procedure explained by dadzie and orchard (1997) was used in this study.
呼吸和乙烯测试
使用二氧化碳/氧气双气体分析仪(ica15，英国ica公司)测量单个香蕉果实的呼吸速率。采用乙烯分析仪(ica56，英国ica)测定了果实乙烯(c2h4)的产率。本研究使用了dadzie和orchard(1997)解释的程序。
