Siirt İlinde Yetiştirilen Zivzik ve Pervari Nar Genotiplerinin Pomolojik ve Fizikokimyasal Özellliklerinin Karakterizasyonu

Abstract

Commercial pomegranate cultivation in Siirt province is concentrated in Şirvan and Pervari districts. Although Zivzik pomegranate variety is a registered pomegranate variety, it is not well known outside the region where it is grown (Zivzik, Sarıdana, Kapılı and Pirinçli villages). Pervari pomegranate is grown in the regions between Bitlis stream, Hizan and Pervari. In this study, pomological and physicochemical characteristics of different sized fruits of Zivzik (n=8) and Pervari (n=10) pomegranate genotypes collected from different locations in Siirt province were investigated. The pomological characteristics examined were fruit weight, aril yield, 100 aril weight, fruit width-length, aril width-length, rind (peel) skin and aril colour, juice yield, juice density and colour. The physicochemical properties analysed were total soluble solids, total acid, pH, ascorbic acid, total sugar, reducing sugar, total phenolic substance, anthocyanin, antioxidant capacity (DPPH), moisture and ash content. It was found that the most abundant organic acid in Zivzik and Pervari pomegranates was citric acid (3.34-4.67 g/L) and malic acid was found more in Zivzik pomegranate (1.76 g/L). Zivzik pomegranate was found to be richer in terms of the amount of phenolic compounds. Quercetin and caffeic acid are the most abundant phenolic compounds in the fruit of both varieties.
