摘　　要： 催熟温度越高,激发果实产生的乙烯和CO_2量越多,呼吸跃变期越早出现,果皮颜色变化越快。但温度在26℃以上,果皮转黄受到抑制。果实在30℃催熟约3天,果肉已成熟,但果皮仍基本是绿色,仅带微黄,颜色指数在3以下。建议香蕉催熟周期为5～7天,催熟温度17～21℃,乙烯利浓度500～1000ppm。提高温度或增加乙烯利浓度虽可加快成熟速度,但导致果肉迅速变软和货架寿命缩短。乙烯的大量释出比呼吸跃变期早出现。呼吸跃变期随乙烯利浓度增加而提早出现。不同的果实饱满度和采收季节对催熟处理的敏感性有差异。 The respiration rate and elhylene production of banana increased at higher temperatures. The higher the temperature, the earlier climateric occured. The peel colour also changed more rapidly at higher temperatures. However, the Chang in colour from green to yellow was inhibited at temperature higher than 26℃ . The pulp was found to ripen in 3 days after a treatment with ethephon at 30℃. but the peel colour was still green with only a trace of yellow colour index below 3). A 5 to 7 days ripening cycle was found to be the best. The temperature from 17 to 21 ℃ and the ethephon concentrations from 500 ppm to 1 000 ppm were demonstrated to be optimum for the ripening treatment of banana. High temperatures and high concentrations of ethephon might accelerate the softning of pulp and shorten the shelf life. A great amout of the ethylene released before the climateric taking place, and the climateric was observed to appear earlier at higher concentration of ethephon. The sensitivity of banana to the ripening temperature and ethephon varied with the stages of fruit matunity and harvesting seasons.
