Özet
Due to its different ecological conditions, Türkiye is one of the rare countries where the most of fruit species have spread widely throughout the country, both economically and naturally. In this study on apple, which is one of the important fruit species with economic importance, was aimed to determine the color characteristics, biochemical and sugar contents of 4 different commercial apple cultivars grown in the ecological conditions of Çarşamba district of Samsun province. The material of the study consisted of 6-7 years (2016 and 2017) old trees belonging to Granny Smith, Fuji, Galaxy Gala, and Royal Gala cultivars grafted on M9 clone rootstock. Wide variations occurred in all parameters evaluated in the study among the cultivars. The fructose content of the cultivars was from 14.22 (Royal Gala) to 34.40 g 100 ml-1 (Fuji), glucose content was from 1.30 (Galaxy Gala) to 4.34 g 100 ml-1 (Fuji), and sucrose content was varied from 2.01 (Fuji) to 4.52 g 100 ml-1 (Granny Smith). The highest value in total sugar content was determined in Fuji cultivar with 40.75 g 100 ml-1. The highest total phenolics, total flavonoids and antioxidant activity (according to DPPH and FRAP) were 423.7 mg 100 g-1 (Granny Smith), 96.1 mg 100 g-1 (Fuji), 250.8 µmol 100 g-1 (Granny Smith) and 952.9 µmol 100 g-1 (Granny Smith), respectively. In the principal component analysis results, the first component was associated with a*, b*, hue angle, total phenolics, total flavonoids and antioxidant activity (DPPH and FRAP) and explained 59.4% of the total variation. The second component explained 36.4% of the total variation of the obtained data and was determined to be related to L*, chroma, glucose, sucrose, fructose, and total sugar properties. As a result, Granny Smith cultivar gave remarkable results in terms of biochemical properties and Fuji cultivar in terms of sugar content. It is thought that the results obtained may guide the researches to be made about apples in this region.
