Abstract: Storabilities of plum fruits of different cultivars including the early-maturing cultivars‘Beauty', ‘America1', ‘Zongtong', the medium- maturing cultivar ‘Yuhuang 'and the late- maturing cultivars ‘Friar Plum'and‘Australia 14'at the storage condition of ( 0 ±0.5) ℃ and relative humidity 80%~90% were investigated.The fruit firmness, soluble solid content ( SSC) , pH, content of titratable acid, weight loss rate, juice yield, and ethylene releasing rate were measured and the differences of storability were analyzed and compared among the selected cultivars of the fruits.Results showed that the‘Yuhuang'plum had the best storability, followed by‘Australia 14'and ‘Friar Plum', the‘Beauty'plum was soft, juicy and had a fuller flavour, but its SSC was low.‘America 1'and‘Zongtong'plum got softening quickly and were sensitive to decay.These results provided a theoretical criteria and application base for revealing the storability difference at low temperature among different cultivar plums.
