Some Physical Properties of Sweet Cherry (Prunus avium L.) Fruit

4 Abstract: Information about physical properties of cherry fruit is very important for understanding the behavior of the product during the post harvest operations such as harvesting, transporting, sorting, grading, packaging and storage processes. This research was undertaken to study some physical properties of six Iranian sweet cherry cultivars (Mashad, Siah Mashad, Dorageh Karaj, Shabestar, Siah Daneshkadeh and Ghazvin). These properties include: linear dimensions, geometric mean diameter, projected area, criteria projected area, surface area, sphericity, volume, mass, bulk and fruit density, packaging coefficient, static coefficient of friction and ratio of length to width, length to thickness and length to mass. The peduncle length of cherry fruit varied from 27.04 to 72.1 mm with CV of 18%. The fruit length, width and thickness ranged from 17.92 to 26.78, from 16.50 to 24.57 and from 14.62 to 23.41 with CV of 8.38, 7.71 and 8.53%, respectively. The geometric mean diameter ranged from 16.55 to 24.46 with CV of 7.81%. The criteria projected area of each cherry cultivar resulted in different means, varying from 481.19 to 599.04 mm . The highest and the lowest volume and mass were found 2
