Özet:

 Objective: This study was carried out to determine the effect of kernel size on the change of bioactive compounds in Kalınkara hazelnut cultivar. Materials and Methods: This study was conducted on the Kalınkara hazelnut cultivar grown in a producers orchard in Ulubey Ordu district. The study was designed according to the randomized plot design with three replications and three ocak in each replication. Harvested nuts were classified according to kernel size as small, medium and large. Then, total phenolics, total flavonoids, and antioxidant activity were determined. In addition, correlation coefficients were calculated, and principal component analyses were performed to determine the relationships between the examined features. Results: In the study, it was observed that kernel size was effective on bioactive compounds in Kalınkara hazelnut cultivar. According to the research findings, the total phenolics was determined between 759 mg 100 g-1 medium and 819 mg 100 g-1 large, the total flavonoids was determined between 8.2 mg 100 g-1 medium and 8.7 mg 100 g-1 small, and total antioxidant activity was determined between 0.46 mmol 100 g-1 medium and 0.60 mmol 100 g-1 large according to the FRAP assay, while it was determined between 1.83 mmol 100 g-1 medium and 1.92 mmol 100 g-1 small according to the DPPH assay. In addition, a positive correlation was determined between the total phenolics and antioxidant activity. Accordingly, while the correlation coefficient between total phenolics and DPPH assay was r0.921, it was r0.982 with FRAP assay. Conclusion: As a result of the research, it was determined that the total flavonoids, and antioxidant activity according to the DPPH test were higher in small kernels. In comparison, total phenolics, and antioxidant activity according to the FRAP assay were higher in large kernels.

 Amaç: Bu çalışma Kalınkara fındık çeşidinde meyve iriliğinin biyoaktif bileşiklerin değişimi üzerine etkisini belirlemek amacıyla yapılmıştır. Materyal ve Yöntem: Bu çalışma Ulubey Ordu ilçesinde bir üretici bahçesinde yetiştirilen Kalınkara fındık çeşidi üzerinde yürütülmüştür. Çalışma tedadüf parselleri deneme desenine göre 3 tekerrürlü, her tekerrürde 3 ocak olacak şekilde dizayn edilmiştir. Hasat edilen meyveler küçük, orta ve büyük olarak iç meyve iriliğine göre sınıflandırılmıştır. Ardından toplam fenolik, toplam flavonoid ve antioksidan aktivitesi belirlenmiştir. Ayrıca incelen özellikler arasındaki ilişkileri belirlemek amacıyla korelasyon katsayıları hesaplanmış ve temel bileşen analizleri gerçekleştirilmiştir. Araştırma Bulguları: Çalışmada Kalınkara fındık çeşidinde meyve iriliğinin biyoaktif bileşikler üzerine etkisi önemli bulunmuştur. Araştırma bulgularına göre, toplam fenolik içeriği 759 mg 100 g-1 orta - 819 mg 100 g-1 büyük, toplam flavonoid içeriği 8.2 mg 100 g-1 orta and 8.7 mg 100 g-1 küçük, antioksidan aktivitesi FRAP testine göre 0.46 mmol 100 g-1 orta - 0.60 mmol 100 g-1 büyük, DPPH testine göre 1.83 mmol 100 g-1 orta - 1.92 mmol 100 g-1 küçük arasında belirlenmiştir. Ayrıca, incelenen özelliklerden toplam fenolik ve antioksidan kapasitesi arasında pozitif bir korelasyon tespit edilmiştir. Buna göre toplam fenolik ile DPPH arasındaki korelasyon katsayısı r0.921 olarak belirlenirken, FRAP ile r0.982 olarak tespit edilmiştir. Sonuç: Araştırma sonucunda, küçük irilikteki meyvelerde toplam flavonoid içeriği ve DPPH testine göre antioksidan aktivitesinin, büyük irilikteki meyvelerde ise toplam fenolik ve FRAP testine göre antioksidan aktivitesinin yüksek olduğu belirlenmiştir.
