Acibenzolar-S-methyl (ASM) is a functional analogue of salicylic acid and an artificial synthetic chemical elicitor. ASM has been shown to induce resistance in a wide range of fruit and vegetables. Spraying with ASM before harvest or postharvest dipping treatment decreased postharvest diseases of pear, peach, grape, strawberry, muskmelon, mandarin, banana, loquat, tomato and potato. The resistance induced by ASM is related to various defense responses, including induction of reactive oxygen species accumulation, activation of phenylpropanoid pathway and production of pathogenesis-related proteins. Range of fruit and vegetables of ASM application, the efficacy of ASM and mechanisms involved in induced resistance with ASM are still need to be investigated in future researches.%苯丙噻重氮(acibenzolar-S-methyl,ASM)是水杨酸的类似物,也是人工合成的植物抗病性化学诱导剂,能够诱导多种植物的抗病性.采前或采后ASM处理可有效降低梨、桃、葡萄、草莓、甜瓜、橘、芒果、香蕉、枇杷、番茄和马铃薯等多种果蔬的采后病害.ASM的诱抗机理涉及诱导活性氧的积累、活化苯丙烷代谢和促进病程相关蛋白的产生等方面.本文还对扩大ASM的使用范围,提高其使用效果,以及深入阐明ASM的作用机理进行了展望.
