Abstract:
Ten apricot varieties，including two kernel apricot and eight flesh apricot cultivars were used as materials for assaying contents of soluble total sugar，reducing sugar and titratable acid in flesh，and anthocyanin，chlorophyll，carotenoid and flavoniod in flesh and peel during the ripeness.Flesh apricots were separated according to flesh color into three groups：white，yellow，and orange-yellow.Contents of sugar acid and pigments were compared among different groups.Also the correlation between flesh color and each index was analyzed.The results showed that soluble total sugar was lower and titratable acid was higher in the apricot than in the flesh apricot；the reducing sugar had no significant differences between them.Anthocyanin was only located in the peel of red apricot varieties.As a general rule，in addition to the anthocyanin，contents of pigments in both flesh and peel of kernel apricot cultivars were higher than that of flesh apricot cultivars；the peel tissues contained higher amounts of pigments than the flesh tissues in the same variety.Contents of soluble total sugar，titratable acid，and carotenoid were significantly different among three flesh color groups.The carotenoid content was correlated significantly with the flesh color (r=0.872).No significant correlation between the flesh color and chlorophyll，flavoniod，and sugar acid was observed.
