Abstract
Abstract Bruising in “Aroma”, “Cox's Orange Pippin” and “Ingrid Marie” apples grown in a Swedish research orchard were studied during two seasons—1992, 1993. Incidence was recorded by dropping fruits from 0, 5, 10, 15, 25 and 30 cm. Bruising increased with increasing drop heights, and dropping from higher than 10 cm caused more large bruise areas. The diameter of some bruise areas increased during storage for 2 months. Aroma was the more sensitive cultivar and Cox's Orange Pippin was the more resistive against bruising. In order to compare bruise quantifying methods, we studied number, diameter, weight and volume of bruise. We found that the bruise weight parameter ((bruise weight/fruit weight) × 100) was the most accurate method owing to the correspondence between this parameter and impact energy.
