Abstract: The results showed that the fruit expanding period of Apple Golden Delicious was for about 75 days in the ecological environment.During this period, the fruit volume, weight, total soluble solids (TSS),total sugars had highly positive correlation with development days, While total acids,respiration intensity (RI)had highly negative correlation with development days.There also existed highly positive correlation between fruit volume and weight, fruit volume and TSS,TSS and total sugars,RI and Total acids,RI and ascorbic acid,total acids and ascorbic acid,respectively,while highly negative correlation existed between fruit weight and RI,fruit weight and total acids,RI and total sugars,TSS and total acids,total sugars and total acids,respectively.Linear regression also existed among fruit weight and volume,TSS.total sugars,total acids, RI; TSS and fruit volume, total sugars, total acids, RI; total sugar and fruit volume,total acids,RI,respectively.
