Abstract: To clarify quality change of Hanjiang cherry[Cerasus pseudocerasus（Lindl.） G. Don] during fruits development, the preservation effect of different processing conditions and ambient temperature changes during logistics was analyzed. The changes of single fruit weigh, fruit handle pull, soluble saccharide during fruits development were compared. The marketable fruit rate after pre-cooling and logistics was studied by analyzing the fruit decay rate under different conditions（25 ℃, 0 ℃, 0 ℃+gas modulation, 80% N₂+15% CO₂+5% O₂）. The results showed that the fruit weight of cherry fruit was 0.80, 1.50, 2.34, 3.03, 3.24 g at hard core stage, color changing stage, early well, medium maturity and near maturity respectively. The higher the fruit maturity, the smaller the pull force of fruit stalk. The soluble saccharide value was 7.55%, 10.04%, 13.62%, 15.40%, 16.34%; The decay rate reached to 72% by the fourth day at 25 ℃, but was only 4% under 0 ℃; There was no decay occured under 0 ℃+gas modulation. If treated by pre-cooling for 24 h, the marketable fruit rate was as high as 90% after 41 h of logistics. The preservation effects of Hanjiang cherry under gas modulation +low temperature was superior to single low temperature.
