摘 要 ：水杨酸（salicylic acid, SA）作为植物体内一种内源信号分子，具有多种生理功能，尤其与通过诱导气孔关闭提高植物的抗病性密切相关。以蚕豆气孔为材料，利用表皮条生物分析、膜片钳等手段研究表明，SA浓度在1~1 000 mol L^-1时诱导的气孔关闭具有可逆性，而10 mmol L^-1时导致的气孔关闭不可逆

Abstract:Salicylic acid is an endogenous signal compound with many functions especially in disease-resistance in plants. Previous studies have suggested that SA can inhibit catalase, resulting in elevated levels of H₂O₂, which activate defense responses in plants. At present, it is acce
