Abstract
Effects of the storage period and fruit portions on the resistivity of ‘Kokko’ apples to impact and compression were investigated.1. In the fruits stored for 2 to 3 weeks, the mechanical injuries caused due to impact by dropping onto the board from the height of 5-10cm, or compression by loading to 20kgW at a speed of 2mm/min, seemed to be alleviated. However, in case the impact was given by dropping fruits from the height of 30-50cm, no differences of injuries were observed among the lots with different storage periods.2. The resistivity to mechanical injuries showed some relation with the percentage of permanent deformation, but not with fruit stiffness or the flesh firmness within the scope of this experiment.3. Concerning the resistivity of fruit portions to impact, cheek, equatorial portion of fruit was somewhat susceptible compared with calyx and stem ends.
