Fruit Quality, Anthocyanin, and Cyanidin 3-Glucoside Concentrations of Several Blood Orange Cultivars Grown in Different Areas of Iran

摘要

Fruit quality and its appearance are very important from consumer's view point. The fruits of 'Moro', 'Tarocco', 'Sanguinello', and 'Sanguine' blood orange cultivars were harvested at the stage of commercial maturity in Kotra (North) and Darab (South) counties in Iran. After harvesting, the fruits were analyzed for Hunter value, total soluble solids (TSS) content, titratable acidity (TA), and concentrations of anthocyanin and cyanidin 3-glucoside. 'Tarroco' fruits from Darab region showed high Hunter L value (70.3). The oranges harvested in Kotra had a hue angel value of more than 80. Chroma values were at the highest amount in 'Tarocco' with 70.6 values. Generally, TSS was higher in the cultivars grown in south than north. 'Sanguinella' and 'Sanguine' fruits had the highest TA in both regions. Cyanidin 3-glucoside contents of 'Tarocco' (South) and 'Moro' (North) were 368.2 and 196.05 mg.L-1, respectively, which were higher than the others. However, 'Sanguinello' and 'Sanguine' fruits gown in the southern region contained higher amount of cyanidin 3-glucoside than those in the northern area. In this experiment, we found that climate was the major influence on main component and anthocyanin of fruits. 'Tarocco' and 'Moro' fruits had high quality in south and north counties, respectively.
