从贮藏温度和贮藏期两个方面探讨了西瓜冷害的发生情况以及冷害症状与呼吸强度变化的关系。结果表明,西瓜‘丰收2号’品种在14、16和20℃贮藏一个月,无冷害发生;12℃贮藏5-10天,0-10℃贮藏5-6天无冷害或只有轻微的冷害,以后随贮期延长冷害加重。在冷害症状出现之前,升温到20℃后呼吸强度即表现出异常升高。随着贮藏温度的提高腐烂明显增加。 The relationship between chilling damage and changes of chilling injury and respiration intensity were discussed from two aspects of storage temperature and storage period. The results showed that the watermelon ’Fengshu 2’ was stored at 14, 16 and 20 ℃ for one month without chilling injury; stored at 12 ℃ for 5-10 days, stored at 0-10 ℃ for 5-6 days without chilling injury or with slight chilling injury, With the prolonged storage of chilling injury worse. Before chills symptoms appear, the respiration intensity shows an abnormal increase after warming to 20 ° C. With the storage temperature increased decay significantly increased.
