An experiment was carried out to study the postharvest physiological changes of mango cv. Hainan-Qiumang fruits stored at room temperature (28-35 deg C). Respiration rate reached a peak on the 6th day of storage. Simultaneously, fruit colour changed from green to yellow. Up to the 11th day, the peel fully changed yellow as fruits became softer. The activities of polygalacturonase (PG) and protein esterase (PE) [pectinesterase?] in peel and pulp increased with softening. These activities were higher in the peel than in the pulp, especially PE activity, which in the pulp was only 39% of that in the peel. The activity of polyphenol oxidase (PPO) [catechol oxidase] during storage gradually decreased and the activity of peroxidase (POD) increased. The activities of PPO and POD had no relation with fruit softening. The activity of cellulase in the peel decreased, but that in the pulp clearly increased, reaching a peak on the 7th day of storage then decreasing.
