Sažetak

Fruit samples of ‘Granada’, ‘Wonderful’ and ‘Hicaznar’ cultivars were collected in productive pomegranate orchard in Neretva valley, Metković (Croatia) and their pomological and chemical properties were compared. Significant differences among cultivars were noted between the studied traits. Fruit weight ranged from 429.37 g to 359.43 g and the lowest was recorded in cv. ‘Hicaznar’. Color of peel, aril and juice of all investigated cultivars was intensively red and dark red, respectively. ‘Granada’ and ‘Wonderful’ stood out with high juice yield compared with ‘Hicaznar’. Total soluble solid (TSS) of ‘Hicaznar’ (18.61%) was higher than that of ‘Wonderful’ (16.64%). Total acidity (TA) significantly differed among cultivars and ranged from 1.6% to 2.1%. According to the TSS/TA ratio investigated cultivars belong to the group of sour-sweet cultivars. Dissimilarity between cultivars was found in the phenolics content (TPC). It ranged from 679.6 to 906.6 mg/100 g D.W. where ‘Hicaznar’ stood out as a cultivar with highest TPC and also highest flavonoid and non-flavonoid content (521.1 mg/100 g D.W. and 385.5 mg/100 g D.W., respectively). In ‘Granada’ antioxidant activity measured by 1,1-diphenyl-2-picrylhydrazyl was recorded for 64.1%, in ‘Wonderful’ 70.2% and the highest in ‘Hicaznar’ (74.5%). Results of this assessment are the basis for practical determination of the pomegranate use.
