Description
Summary:The influence of harvest date and storage method on bruises sensitivity of apples was investigated. The cultivars 'Braeburn', 'Jonagold' and 'Golden Delicious' were harvested at three times in an interval of 10 days. Fruits have been stored at 2°C in normal atmosphere (cold storage) or in film bags (CA-/ULO-storage; CA=Controlled Atmosphere, ULO=Ultra Low Oxygen) for three months. Monthly fruits were bruised by a penetrometer applying a range of pressures. One day later the appearance of bruises were evaluated. Increasing pressures resulted in bruises of increasing severity. Early harvest led to less severe bruises. No differences were observed in storage conditions, but duration of storage increased bruise sensitivity of 'Braeburn'. In comparison of the three cultivars 'Braeburn' was less sensitive than 'Jonagold' and 'Golden Delicious'.
