plum cultivar s ,i.e.Ooisiwase,Longyuanqiuli,Fraiar,Angeleno,were used in this study.The result showed that chlorophyll,carotenoids,total phenolics and flavonoids con tents in the fruit skin decreased during fruit development ,whereas contents of sugars and anthocyanin and activity of polyphenol oxidase(PPO)increased.Exce pt relationship among sucrose,glucose contents and anthocyanin content in Ang eleno,there was marked correlation between anthocyanin and total sugar,sucrose ,fructose,glucose.There was marked relationship between sucrose and anthocyan in in cv.Ooisiwase(r=0.9688),cv.Longyuanqiuli(r=0.9481 ),cv.Fraiar(r=0.9447);between anthocyanin and fructose in cv.Ooi siwase(r=0.9438),cv.Longyuanqiuli(r=0.9763),cv.Fra iar(r=0.9358),cv.Angeleno(r=0.8925);between antho-cyan in and glucose in cv.Ooisiwase(r=0.8940),cv.Longyuanqiuli(r=0. 9022),cv.Fraiar(r=0.9424).The total phe-nolics had been sh owed to be negatively correlated with PPO activity in cv.Longyuanqiuli(r=-0 .9896)and Fraiar(r=-0.9664).
