摘　　要：用0.5%、1%、2%和4%浓度的蔗糖基聚合物对香蕉进行采后涂膜处理,研究其对香蕉果实及果皮中超氧化物歧化酶(SOD)和过氧化物酶(POD)活性的影响。结果表明,香蕉采后进行蔗糖基聚合物涂膜,可以提高SOD,降低POD活性,在延缓果实组织的衰老,延长贮藏寿命方面有较好的效果。Murcott post-harvested was treated by sucrose-based polymers with concentration of 0.5%, 1%, 2% and 4%. The activities of Superoxide dismutase（SOD） and Peroxidase（POD） in the banana fruit and peel were investigated. The results showed that sucrose-based polymers could enhance SOD activity, decrease POD activity, and slow obviously decay of fruit, prolong the storage life.
