摘　　要：[Objective] This study aimed to evaluate the effects of exogenous salicylic acid derivatives on tobacco resistance to TMV and activity of defense enzymes. [Method] The tobboco leaves were treated by exogenous salicylic acid derivatives. Then, the disease occurrence was observed, and the activity of phenylalanin ammo- nia lyase （PAL） and peroxidase （POX） were measured. [Result] Exogenous salicylic acid derivative increased the activities of PAL and POX, while did not influence the resistance to TMV. [Conclusion] The result provides a theoretical basis for the study of plant disease resistance mechanisms.[目的]研究水杨酸衍生物是否可诱导烟草抗TMV,及其对几种防御酶活性的影响。[方法]用外源水杨酸衍生物处理烟草以诱导其对烟草花叶病毒的抗性,并测定其对接种TMC的烟草叶片中防御酶苯丙氨酸解氨酶(PAL)、过氧化物酶(POX)的活性。[结果]水杨酸衍生物处理可使烟草叶片中PAL、POX活性有不同程度的提高,但对烟草花叶病毒的抗性影响较小。[结论]该研究为植物抗病机制的研究提供了理论依据。
