İzmir İlinde Yetiştirilen Bazı Önemli Kiraz Çeşitlerinin Fiziksel ve Kimyasal Özelliklerinin Belirlenmesi

Abstract

Physical and chemical properties of cherry fruits, which are quality indicators of cultivars, may differ greatly among cherry cultivars depending on the cultivation ecology. In this study, we aimed to determine the physical and chemical properties of some important cherry cultivars grown in Kemalpaşa County of Izmir Province, Turkey. We determined physical and chemical characteristics of cherry cultivars harvested at full maturity in the Kemalpaşa region. These included Bing, Early Burlat, Early Lory, Napolyon (also known as Napoleon), Sapıkısa, Stella, Regina and 0900 Ziraat cherry cultivars grafted onto Ziraat Prunus mahaleb L. rootstocks. The Regina and 0900 Ziraat cultivars had the highest fruit diameter, fruit weight, fruit firmness and tensile strength, whereas the Sapıkısa cherry cultivar yielded the lowest results for the same parameters. The Stella and Bing cultivars showed the highest C* and h° values for color parameters. The Napolyon cherry cultivar had the highest water-soluble dry matter and total phenol content; based on individual cultivars, these parameters varied from 9.86% to 16.13% and from 83.4 to 99.8 mg GAE/100 g, respectively. The Bing cherry cultivar had the highest TA content, whereas it had the lowest pH value. The Early Lory cherry cultivar yielded the highest antioxidant activity ( 15.19 µmol TE/g) , whereas the 0900 Ziraat cultivar yielded the lowest activity (9.77 µmol TE/g). This study revealed significant differences in several of the physical and chemical properties of important cherry cultivars grown in the Kemalpaşa region.
