Abstract
Fruit samples of domestic (Barski slatki, Ciparski, Glava and Sladun) and foreign pomegranate cultivars (Granada, Hicaznar and Wonderful) were collected in productive pomegranate orchard in Metković (Croatia) and compared their pomological and chemical properties.
The results on the main pomological and quality traits indicated significant statistical differences among domestic and foreign cultivars.
Fruit weight of investigated cultivars varied from 510.5 to 355.1 g and the highest was recorded in Glava, while difference in fruit weight between other cultivars was not found.
Color of peel, arils and juice of domestic cultivars was yellow to red, red and light red to red, receptively, while in the foreign cultivars intensively red and dark red.
Arils yield of Barski slatki and Ciparski (57.7 and 60.8%, receptively) was higher compared with other investigated cultivars.
Juice yield of domestic cultivars was higher than that of foreign.
Total soluble solid (TSS) of Hicaznar (18.6%) was higher than that of Barski slatki (17.0%), Ciparski (14.7%) and Wonderful (16.6%). Total acidity
(TA) of Glava (2.24%) and Hicaznar (2.08%) was the highest while of Barski slatki (0.58%), Ciparski (0.37%) and Sladun (0.59%) the lowest.
According to the TA and (TSS/TA) Glava and foreign investigated cultivars belonged to the group of sour-sweet cultivars while Barski slatki, Ciparski and Sladun belonged to the sweet cultivars.
Foreign cultivars had higher total phenolic content (TPC) that ranged from 679.6 to 906.6 mg 100 g‑1 d.w., than domestic ones. Hicaznar stood out as a cultivar with the highest TPC and anthocyanin content (86.3 mg 100 g‑1 d.w.). Non-flavonoid content in studied cultivars ranged from 160.6 to 385.5 mg 100 g‑1 d.w. and antioxidant activity measured by 1,1-diphenyl-2-picrylhydrazyl from 60.2 to 74.5%. Results of this survey are a basis for use defining of the pomegranate fruit.
