Abstract
Investigated antioxidant levels of 30 pomegranate genotypes via FRAP, DPPH, iron-chelating methods in this study. Pomegranate genotypes were collected from the several orchards located in Sarıdana, Kapılı, Pirinçli and Zivzik villages of Şirvan district, at Siirt province in Southeastern Anatolia of Turkey and were numbered from 1 to 30. 26 genotypes studied in the study are Zivzik pomegranate clones. Four of 30 genotypes, which have different fruit characteristics from Zivzik variety. These four genotypes are called as Asili (Genotype 21), sour pomegranate (Genotype 22 and 23) and red pomegranate (Genotype 24). The difference in antioxidant levels of genotypes, determined by FRAP method were assessed using one-way analysis of variance. The results of ANOVA indicated a statistically significant difference in absorbance values between the genotypes (p<0.001). Therefore, the genotypes were grouped based on absorbance values by Tukey's multiple comparison test. Test results showed that genotypes 30, 16, 22 and 29 had the highest antioxidant level, the mean antioxidant levels of 13, 23, 28, 18,14, 9, 6, 12, 2, 4, 5, 3, 17, 27 and 11 genotypes were similar, and genotypes 15, 1 and 7 had the lowest antioxidant levels.
