The results showed that there were important significant differences among the cultivars in most of the parameters that were measured. Among the cultivars, Black cultivar had the highest fruit mass(207.65 g), followed by Big Ariane(188.34 g) and Medium Ariane(137.49 g). The actual fruit volume(cm~3) ranged from 61.77(Apricot) to 269.67(Black). The highest geometric, arithmetic, square and equivalent mean diameter values were observed for Big Ariane. The surface area and projected area of cultivars were between 14.53-69 cm~2 and 45.56-165.33 cm~2, respectively. The maximum coefficient of static friction was obtained on plastic followed by steel, iron and glass; the maximum coefficient of dynamic friction was obtained on glass followed by steel, plastic and iron.展开更多
