| 中文摘要: |
| 以海南省龙眼主栽品种“储良”（CL）和“石硖”（SX）为试材，比较了两种龙眼种子的大小、果皮和果肉厚度、果皮色泽等外观品质特性。并分别在冷库（6±1）℃、相对湿度75％、内衬有孔塑料袋纸盒外包装的条件下贮藏17 d，测定和分析了2种龙眼的低温贮藏性能。结果表明，SX果实较小、果皮厚且粗糙、果肉清脆；CL果实较大，果皮薄且光滑，果肉绵软。采后低温贮藏期间，SX龙眼果肉可滴定酸（TA）含量变化较缓慢，贮藏17 d时，SX龙眼果实好果率、果肉可溶性固形物含量（SSC）、VC、还原糖含量显著高于CL果实（P＜0.05），SX果实呼吸强度、果皮相对电导率、丙二醛（MDA）含量、果肉褐变度、多酚氧化酶（PPO）活性和过氧化物酶（POD）活性均低于CL果实。综上所述，SX龙眼果实在耐低温贮藏方面明显优于CL龙眼果实。 |

| Seed size， pericarp and flesh thickness，fruit color of Chuliang（CL） and Shixia（SX） longan fruits from Hainan province were compared in this paper.At the same time，the low temperature storage performance of two cultivars of longan fruits packed in plastic bags with holes inside and carton outside and storaged at（6±1）℃ and 75% relative humidity for 17 days was determined and analyzed. The results showed that compared with CL longan,SX longan had smaller fruit, thicker and rougher peel, and crisper flesh. There was no obvious differences in TA content of SX longan flesh during cold storage, after 17 days of storage，the marketable fruit rate, SSC,VC and reducing sugar contents of SX longan were significantly higher than those of CL longan，while the fruit respiration rate，relative electrical conductivity of peel，MDA content，Flesh Browning degree，PPO and POD enzyme activity of SX were all lower than CL longan. In conclusion, the low temperature storability of SX longan was significantly higher than thatof CL longan. |
