Fruits of 3 plum cultivars were stored in air or in controlled atmosphere (CA) storage (3% O2 + 5% CO2) in cycles of 10 days at -0.5 deg C and 18 days at 7.2 deg . Some fruits were stored in partial CA storage consisting of 2% O2 + 5% CO2 at -0.5 deg for 10 days, followed by cycles of 18 days at 7.2 deg and 10 days at -0.5 deg in air. Other fruits were subjected to prestorage conditioning consisting of 2 days at 20 deg in 21% O2 + 5% CO2 followed by cycles of 10 days at -0.5 deg and 18 days at 7.2 deg in air. The fruits were stored for 4-8 weeks and held after storage at 10 deg C for 7 days. Laetitia plums could be stored for 8 weeks, followed by 7 days at 10 deg . Continuous CA storage, partial CA storage and prestorage conditioning all gave good results with this cultivar. Casselman fruits could also be stored for 8 weeks plus a further 7 days at 10 deg . The best treatments for this cultivar were continuous CA storage and partial CA storage. For Songold fruits, continuous CA storage gave the

best results and the maximum storage time was 7 weeks, followed by 7 days at 10 deg . The incidence of decay was low throughout in all cultivars and treatments, but wilting, although of a light intensity, was too high after 8 weeks. Shorter storage periods resulted in less wilting.
