摘　　要：以大泽山葡萄果实为试材,采用浓度0.5%、1.0%、2.0%、4.0%的壳聚糖溶液浸泡果实l min,在室温下贮藏12 d,研究了壳聚糖涂膜处理对葡萄果实贮藏品质的影响。结果表明:与对照相比,4种壳聚糖涂膜处理均可不同程度降低果实的失重率和腐烂率,抑制果实贮藏后期可溶性固形物含量下降,保持果实较好的硬度。同时抑制呼吸作用,提高果实中抗氧化酶活性,延缓了果实的成熟衰老。其中1.0%壳聚糖涂膜处理的果实贮藏12 d,其腐烂率和失重率分别为12.8%和3.34%,而对照的分别是27.3%和6.46%,与对照的差异显著,果实品质好,保鲜效果最佳。The effect of chitosan coating on grapes postharvest quality were studied in different concentration,0.5 %, 1.0%,2. 0%, and 4. 0%, under room temperature. The results showed that each treatment could reduce the weightless rate and rotten rate, restrain the reduce of soluble solid content during storage. It also could stave the senescence by restrain the respiration and improve the antioxidation enzymes activity. The treatment of 1.0 % chitosan coating could reduce the weightless rate and rotten rate significantly on 12 d after storage. Altogether, the quality of grapes with 1.0 % chitosan coating was quite better than control and other treatments.
