Abstract : The postharvest physiological characteristics of mango (Mangifera indica cv. Hongxiangya and Wacheng) at different storage conditions were investigated. The respiratory rate, total sugar, vitamin C (Vc) content, firmness, polyphenol oxidase [catechol oxidase] (PPO) and peroxidase (POD) were determined. The results showed that both 8 and 11°C were the better storage temperatures, and the storage life would last 50 days in this situation. The respiration rate increased quickly between the 16th and 22nd days; the peak values were on the 28th and 25th days at 8°C for the Hongxiangya and Wacheng cultivars, respectively. The flesh firmness decreased dramatically at 6 days after harvest. The total sugar, Vc, PPO and POD levels were increased at first and then decreased. The colour changed from green to yellow with the increase of carotenoid content. After treatment with thiophanate and iprodione, the number of rot fruits was markedly lower than the other treatments. The best temperatures were 11 and 14°C for Hongxiangya and Wacheng, respectively. The rot rates were 6.77 and 8.33% with 1000 ppm iprodine treatment after 50 days of storage, respectively. It is suggested that the storage technology of mango still needs further study.
