Geometrical, volumetrical, colour and chemical properties of Malus floribunda as affected by maturity level and fruit size

In this study, the geometrical properties (length, width, thickness, geometric mean diameter, sphericity, surface area), volumetrical properties (fruit mass, fruit volume, bulk and fruit density, porosity), colour characteristics (L*, a*,b*, Chroma, hue angle) and chemical properties (pH, soluble solid content, total acidity) as affected by maturity (semi- maturity,full maturity) and fruit size (big, medium, small) of Malus floribunda fruits were investigated. The geometric mean diameter and fruit mass were changed from 27.01 to 27.44 mm; 10.86 to 11.67 g according to the maturity level of Malus floribunda fruits, whereas, thegeometric mean diameter and fruit mass were varied from 22.89 to 31.69 mm and from 6,46 to 16,69 g according to fruit size differences, respectively. Chemical properties such as pH,soluble solid content, and total acidity ranged from 3.20 to 3.28; 12.89 to 14.06%; 1.00 to 3.20% for Malus floribunda fruit maturity level, respectively.
