The Effect of Region on Nut and Biochemical Traits of Mincane Hazelnut Cultivar

Abstract

Abstract: This study investigated the effect of region on the nut and biochemical traits in Mincane hazelnut cultivar. The study was carried out in the Trabzon (Black Sea Region) and Sakarya (Marmara Region) districts, in 2021 and 2022. The material of the study consisted of the nut of Mincane hazelnut cultivar grown in both regions. Depending on regions, nut weight ranged from 1.89 (Black Sea) to 2.14 g (Marmara), while kernel weight ranged from 0.96 (Black Sea) to 1.06 g (Marmara). The nuts obtained from the Black Sea region yielded the highest total phenolics (118.1 mg 100 g-1). Marmara region’s nuts had the highest total flavonoids (8.1 mg 100 g-1) and antioxidant activity (1027.8 and 738.1 µmol 100 g-1 according to DPPH and FRAP assays, respectively). The results demonstrated the significance of the growing region on the investigated nut and biochemical traits and the superiority of the Marmara region on many quality traits.
