| 摘 要： | 目的]探讨水杨酸（SA）处理对铅胁迫下花椰菜生长特性及生理生化指标的影响，为植物生物修复技术提供参考。方法]以浓度为0、0．01、0．10、0．50、1．00、1．50和2．（30mmol／LPb^2＋胁迫下的花椰菜品种“JR00X”为材料，采用0．05mmol／L SA与未施SA进行处理。研究sA处理对铅胁迫下花椰菜生长特性及生理生化指标的影响。结果]花椰菜种子在铅胁迫期间，发芽率、发芽指数、根长、单株鲜重和活力指数均随pb^2＋浓度增加而降低；当pb^2＋浓度较低时，与未施SA相比，SA与铅同时处理种子萌发率升高，当铅浓度过高（1．5mmo]／L以上）时，SA处理效果不明显，幼苗生长严重受抑制；与未施SA相比，SA与铅同时处理MDA和可溶性糖含量明显降低，且随着pb^2＋离子浓度的升高MDA和可溶性糖含量升高缓慢。结论]SA处理在一定程度上缓解了铅胁迫对花椰菜幼苗的毒害作用。
