Abstract: The post-harvest physiology and mechanism of pericarp browning in different pomegranate cultivars were studied.The result showed that soluble solids,and titratable acid content of pomegranate fruits decreased gradually during storage.Meanwhile,the MDA content and membrane permeability of pericarp slowly increased.The peel polyphenol oxidase activity of different varieties showed a declining trend and the content of phenolic substances declined slightly after the early increase with extension of preservation.The pericarp browning index was negatively correlated with the changes in phenolic substances content during storage period,but not highly correlated with the polyphenol oxidase.Pericarp browning sensitivity of the three varieties,from high to low,was Xinjiang biger seeds pomegranate,Taisan Hong,Mengyang Hong.
