Pomological and Biochemical Characteristics of Local Pomegranate Genotypes of Kahta (Adıyaman) Region

Abstract

In the study carried out to determine the pomological characteristics of local pomegranate genotypes grown in Kahta district center and Bostanli, Eceler, Balli, Kilisk, Sarica, and Narince villages of Adıyaman province, one orchard belonging to a grower in each region and 1 genotype in each orchard were determined. 10 fruits in each genotype were harvested, and pomological measurements and biochemical analyses were performed. The largest fruit was obtained with the Sarıca genotype and Narince was the genotype with the smallest fruit. In genotypes, the fruit weight was between 196.300-328.909 g, the fruit length 61.528-72.801 mm, and the fruit width between 73.047-86.613 mm. Total aril weight was between 94.144-203.567 g and the fruit volume was between 188.333-327.000. The Sarıca genotype had the highest juice volume and the lowest juice ratio was recorded in the Eceler genotype. Calyx length was longer in the Sarıca genotype and the highest values in terms of calyx radius were recorded with the Kilisk genotype. The Eceler genotype had thicker shells and the Narince genotype had thinner shells. The number of chambers in the genotypes was between 5 and 6. There were significant differences between genotypes in terms of fruit skin and aril color. The soluble solids content (SSC) in genotypes was determined between 12.011-17.267, pH was 3.583-4.073 and total acidity (TA) was 0.736-1.489%. Phenolic compounds such as protocatechuic acid, rutin, gallic acid, chlorogenic acid, epicatechin, ferulic acid, floridzin, vanillic acid, hydroxycinnamic acid, catechin, caffeic acid, syringic acid, and p-coumaric acid were detected in pomegranate fruit, and rutin was phenolic compound with the highest concentration.
