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)在三種儲(chǔ)存條件下儲(chǔ)存(11–12℃和95.5%rh；20–22℃和82–85%rh；循環(huán)冷卻和加熱以模擬香蕉收獲季節(jié)的白天/夜間條件：28℃和50%rh/18℃和70%rh)。冷藏貯藏、正常貯藏和循環(huán)晝夜貯藏的果實(shí)貯藏壽命分別為21天、10天和8天。在高溫貯藏和晝夜循環(huán)條件下，果實(shí)成熟、呼吸和乙烯產(chǎn)量顯著提高，導(dǎo)致果實(shí)變質(zhì)更快。在這些貯藏條件下，果實(shí)的失重率、硬度、*損失和葉綠素降解率均高于冷藏條件。

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.
呼吸和乙烯測(cè)試
使用二氧化碳/氧氣雙氣體分析儀(ica15，英國(guó)ica公司)測(cè)量單個(gè)香蕉果實(shí)的呼吸速率。采用乙烯分析儀(ica56，英國(guó)ica)測(cè)定了果實(shí)乙烯(c2h4)的產(chǎn)率。本研究使用了dadzie和orchard(1997)解釋的程序。
