abstract
banana is a really chilling injury sensitive product. its sensitivity to cold temperatures generates serious practical, economical and commercial problems. chilling injury related physiological responses of cavendish type green banana samples stored at 2.5, 5, 10 °c and near optimal (15 °c) cold storage temperature were investigated by nondestructive optical methods (surface color and chlorophyll fluorescence measurement, da-index® evaluation) and by the determination of the physiological reactions (respiration, ethylene production, symptom manifestation) during cold storage and the 8-day long subsequent shelf-life. the positive effects of low temperature storage were proven on mass loss, respiration and ethylene production. in case of bananas stored at 2.5–10 °c, the chilling injury related changes in chlorophyll content related da-index®, ir-values; fm and fv chlorophyll fluorescence values, the l*, a*, b*, c* and hue angle color characteristics suggested clearly from day 3 the onset of chilling injury several days before the visible signs of chilling injury appeared.
香蕉是一种非常耐寒的对伤害敏感的产品。它对低温的敏感性产生了严重的实际，经济和商业问题。通过无损光学方法(表面颜色和叶绿素荧光测量，da-index®评估)研究了在2.5、5、10°c和接近(15°c)冷藏温度下的卡文迪许绿色香蕉样品与冷害相关的生理反应。 )，并确定冷藏期间和随后8天的货架期后的生理反应(呼吸，乙烯生成，症状表现)。低温存储的积极作用已被证明对质量损失，呼吸作用和乙烯生成有影响。如果香蕉在2.5–10°c下储存，则冷害引起的叶绿素含量变化与da-index®相关，ir值；fm和f v叶绿素荧光值，l *，a *，b *，c *和色相角颜色特征从第3天开始明显出现冷害开始，直到出现明显的冷害迹象。
