Abstract

The metabolism of organic acid was closely related to ripening and senescence in the plant tissue. After being treated with an appropriate concentration of citric acid, the physiological activity of the harvested mango fruits was significantly slowed down, and the peak of respiration was delayed, and the peaks of the activities of peroxidase (POX), amylase and polyphenol oxidase (PPO) were delayed, and the peak of the enzyme activities were decreased. But it is no so good results when the mango fruits were treated with a high concentration of citric acid, in comparison with a control. But the peaks of the activities of POX and amylase advanced with high citric acid concentration (≥0.5%). Meanwhile, the activity of PPO was always slow during the storaye.
