Dimensional, Frictional, and Color Properties of Four Quince Cultivars (Cydonia Oblonga Miller)

Abstract

Basic dimensional, frictional and color properties of four quince cultivars, namely 'KA +/- AY AyvasA +/-', 'Anzav Dere', 'Ekmek AyvasA +/-' and 'Ecem', were determined in this study. Physical features, namely length, width, geometric mean diameter, sphericity, aspect ratio, surface area, projected area, volume, mass, static coefficient of friction on aluminum, plywood and steel surfaces, and color features such as L*, a*, b*, hue angle, and chroma were determined and compared for the quince cultivars. The differences among the cultivars were statistically significant in terms of most properties investigated. The values of length, width, geometric mean diameter, sphericity, and fruit mass of four quince cultivars were established between 75.32-91.68 mm, 68.56-90.53 mm, 70.72-90.88 mm, 94.02-99.18 %, and 175.12-329.44 g., respectively. The highest static coefficient of friction (0.47) has observed for aluminum surface as the lowest static coefficient of friction (0.23) has observed for steel surface.
