摘　　要：荔枝果实采后常温条件下贮藏极易褐变、腐烂,低温可以延长果实的贮藏期。以妃子笑荔枝果实为试验材料,通过测定果实不同生理指标,研究预冷和物流方式(低温运输和常温运输)对荔枝采后贮藏期间果实品质的影响。研究结果表明,荔枝采后预冷且低温条件下运输能够较好地维持妃子笑荔枝贮藏期间的果实品质,该方法明显降低了荔枝果实的褐变指数、腐烂率和相对电导率,较好地维持了果实中的可溶性固形物(TSS)、可滴定酸(TA)和VC的含量。研究结果为将来荔枝冷链物流技术的应用和改进提供数据支撑和理论依据。After harvest, litchi fruit highly tends to become browning and decaying during storage at room temperature, while low temperature can prolong its storage time. In this study, using ＇Feizixiao＇ fruits as materials, several physiological parameters were measured to investigate the effects of pre-cooling and logistics condition, including low and room temperature transportation, on postharvest litchi fruit quality during storage. The results showed that the browning index, decay ratio and relative electric conductivity were obviously reduced by pre-cooling combined with low temperature transportation. In addition, the decrease in contents of total soluble solids （TSS）, titratable acid （TA） and Vc was delayed. These results suggest that pre-cooling combined with low temperature transportation can maintain the quality of litehi fruit during storage. Together, our findings will provide data and theoretical basis for the application and improve cold-chain logistics technology of postharvest litchi fruit.
