Abstract

Pomegranate (Punica granatum L.) is native to Iran, and numerous cultivars are cultivated across the country. This study was conducted to evaluate and compare twelve pomegranate cultivars grown in Yazd province. Fruits harvested at the full ripening stage from 32-year-old trees in the Yazd Pomegranate Collection were evaluated using 22 quantitative, qualitative and biochemical traits. The results showed significant differences among the cultivars in all evaluated parameters. Average fruit weight ranged from 134.85 (cv. Suski Ashkzar Yazd) to 315.55 g (cv. Malas Saveh). The proportions of peel, aril, juice, and seeds relative to the total fruit weight varied among cultivars. Total soluble solids ranged from 13.53 to 18.67 °Brix, titratable acidity from 0.44 to 1.83 mg/100 mL and the maturity index from 9.51 to 34.49. The results also showed that total phenol and flavonoids content in pomegranate cultivars ranged from 158.81-332.78 mg GAE/100 mL and 43.79- 91.31 mg CE/100 mL, respectively. Total anthocyanin content ranged from 13.79 to 165.41 mg/L and antioxidant capacity from 36.57 in the Pust Sefid Dezfol to 89.45 % in Suski Ashkzar Yazd cultivars. Overall, the findings demonstrated that the cultivar plays a pivotal role in determining the quantitative, qualitative, and biochemical characteristics of pomegranate fruits.
