摘　　要：为研究不同温度的贮藏前处理对机械损伤苹果果实腐烂的控制作用,以富士苹果为试材,通过人工模拟果柄戳伤和挤压伤(分别记作处理A和处理B),研究3种不同的降温方式(①24h内立即入(0±1)℃冷库降温;②(13±1)℃下放置48h后入(0±1)℃冷库;③常温(20±1)℃放置48h后入0℃冷库,分别记作T1、T2和T3)对苹果果实硬度、呼吸速率、乙烯释放速率、腐烂指数和腐烂率等的影响。结果表明,3种降温方式比较,T2的呼吸速率、乙烯释放速率、腐烂指数、腐烂率和质量损失率均低于T1及T3。(13±1)℃下放置48h后入(0±1)℃冷库对机械损伤果有明显的控制腐烂变质的效果,可有效延长贮藏期。The control effects of different cooling methods on fruit decay of mechanical damaged Red Fuji apple in cold storage were studied. Red Fuji apples were used as the experirnent objects. The crush and pedicel damages of fruit were simulated before the storage period, three cooling methods were as follows： （i） move into 0 ℃ cold storage within 24 hours （T1）; （ii） keep at （13＋1） ℃ for 48 hours and then move into the 0 ℃ cold storage（T2） ; （iii） keep at room temperature （20±1） ℃ for 48 hours and move into （0±1） ℃ cold storage （T3）. The result showed that the respiration rate,magnitude of ethylene peak,mass loss, decay incidence and rotten index of T2 were the lowest in the three treat- ments. In conclusion,to keep at （13±1） ℃ for 48 hours before the 0 ℃ cold storage had good signifi- cant control effects on fruit decay of mechanical damaged Red Fuji apple and extended the storage peri- od effectively.
