摘　　要：为探索适用于甜樱桃的最佳气调贮藏方式,以快速气调（FA）、二段仿生气调（SBA）、自发气调（MA）3种气调方式贮藏＂砂蜜豆＂甜樱桃,研究不同气调方式对甜樱桃冷藏期生理品质的影响。结果表明,冷藏期间FA、SBA、MA处理气调箱中CO2含量分别为4.78%9.47%、0.00%10.37%、0.00%8.17%,O2含量分别保持在11.43%16.12%、10.53%20.90%、12.73%20.90%,而对照处理的CO2含量始终低于1.33%,O2含量始终高于19.57%。从保鲜效果来看,与对照相比,3种气调方式均不同程度地延缓了甜樱桃腐烂率、果梗褐变指数的上升,保持了果实的色泽和硬度,有效抑制了可滴定酸含量及Vc含量的下降速率,使果实保持较好的风味,并控制了呼吸强度和乙烯生成速率的升高,较好地保持了POD和PPO活性。3种气调方式中,快速气调（FA）处理最为有效地维持了甜樱桃的贮藏品质、延缓果实衰老,对＂砂蜜豆＂甜樱桃的贮藏保鲜效果最佳。We used three atmosphere modes, that is, fast atmosphere（CA1）, secondary bionics atmosphere（CA2） and modified atmosphere（MA） to store ＂sha midou＂ cherry, in order to explore optimal atmosphere storage mode for sweet cherry and study the effect of different atmosphere mode on quality of sweet cherry during cold storage. Results showed that CO2 content during FA, SBA, MA was about 4.78%9.47%, 0.00%10.37%, 0.00%8.17%, respectively, and O2 content was kept at about 11.43%16.12%, 10.53%20.90%, 12.73%20.90%, respectively. As to the control group, CO2 contentwas always lower than 1.33% and O2 content was always higher than 19.57%. After treated with three atmosphere modes, the rotting rate of sweet cherry was all decreased and fruit stem browning index was increased to varying degrees, compared with control group. The fruit color and hardness were all well preserved well. All of the three atmosphere modes effectively inhibited the decline of titratable acid and Vc, keep fruit flavor as well, and controlled the increase of respiratory intensity and ethylene production rate. The POD and PPO activity of sweet cherry were also kept well. Among the three modes we studied, fast atmosphere（FA） mode maintain the storage quality of sweet cherry most effectively, using this atmosphere mode, the preservation effect of ＂sha midou＂ cherry was the best.
