We could not achieve the original purpose of the project understanding the mechanism of the injury, but the following findings were made;1. It seems that the main reason for the injury is high CO_2 concn. and the susceptibility of the fruit to CO_2 is enhanced by low-temperature.2. There is a strong correlation between the effect of curing in reducing the injury and weight loss in curing.3. Hot-water-treatment, dipping the fruit for 5 minutes in 50C hot water, has been a reliable treatment to control the injury, and may be commercially feasible.4. Chemical analyses indicate some relationship between reducing sugar, oxidized ascorbic acid, gluconic acid in peel and the development of injury.The following subjects of research and development are suggested;1. Study physiological (respiration etc.) and biochemical (sugars, organic acids and growth regulators such as ABA etc.) Changes in relation to the effect of hot-water-treatment, curing and conditioning.2. Study the optimum curing factors.3. Develop a device of hot-water-treatment for indivisual farmer.4. Study the feasibility of intermitten warming.5. Study the preharvest factors on the storage injury.

我们无法达到了解损伤机制的项目最初目的，但取得了以下研究结果：1。高CO_2浓度是造成损伤的主要原因。低温处理增强了果实对CO_2的敏感性。治疗减轻损伤的效果与治疗中的体重减轻有很强的相关性.热水处理，将果实在50 ℃的热水中浸泡5分钟，是控制伤害的可靠处理，并且在商业上是可行的。化学分析表明，果皮中还原糖、氧化型抗坏血酸、葡萄糖酸等物质与损伤的发生发展有一定的关系。研究生理学（呼吸等）和生物化学（糖、有机酸和生长调节剂如阿坝等）与热水处理、养护和调理效果有关的变化。研究最佳固化条件.开发适合农户个人使用的热水处理装置.研究气候变暖的可行性.研究采前因素对贮藏损伤的影响。
