POMOLOGICAL AND CHEMICAL CHARACTERISTICS OF SWEET CHERRY CULTIVARS GROWN IN DALMATIA, CROATIA

Sweet cherry growing in the Mediterranean area of Croatia has a long tradi-tion because of favourable ecological conditions.
Four local cultivars (‘Gomilička’, ‘Rana Stonska’, ‘Stonska’ and ‘Tugarka’) and five introduced cultivars (‘Burlat’, ‘Garnet’, ‘Isabella’, ‘Summit’ and ‘Van’) were evaluated for ripening time and fruit characteristics.
To assess external and internal fruit quality, the following fruit traits were investigated: weight (g), length, width and thickness (mm), pit weight (g), pedicel length (mm), soluble solids (%), acid content (g/L) and skin colour (L, C, H, CIELAB system). Large differences for particular quality attributes were found between cultivars.
Fruit of ‘Isabella’ and ‘Tugarka’ had mean weights >7.5 g, while those of ‘Burlat’ were less than 5 g.
Fruit soluble solids content varied from 13.1% (‘Tugarka’) to 19.2% (‘Van’), and total acidity varied from 4.8 g/L (‘Rana Stonska’) to 9.3 g/L (‘Van’). The ‘Garnet’ fruits had the highest L values (dark red skin colour). Chroma and hue angle were higher for fruits of ‘Summit’, ‘Isabella’ and ‘Garnet’, and lower for the other cultivars.
