摘　　要：壳聚糖是一种天然的阳离子聚合物,对许多细菌、真菌有很好的抑制作用,在控制果蔬等植物病害方面极具应用前景。壳聚糖作为果蔬等植物抗性反应的激发子,它能迅速激发果蔬等植物的防卫反应,包括诱导植保素、病程相关蛋白、蛋白酶抑制剂、木质素和胼胝质等的合成,启动果蔬等植物的防御系统,有效地提高果蔬的抗病性。Chitosan,an important natural biopolymer, shows a good inhibition for bacteria and fungi and has potential using in controlling diseases of fruit and vegetable. Chitosan, as an elicitor of resistant reaction for fruit and vegetable, can rapidly stimulate defense responses of plant such as fruit and vegetable, which induce the synthesis of phytoalexin, pathogenesis-related （PR） proteins, protease inhibitors, lignin and callose. Moreover, chitosan, startups defensive system of plants such as fruit and vegetable, and effectively improve disease resistance of fruit and vegetable.
