摘　　要：[目的]初步研究丁香酚对植物病毒病的作用机制。[方法]利用盆栽法测定了丁香酚对烟草花叶病毒病的预防和治疗效果;电镜法观察了丁香酚对病毒粒子的影响;体外混合法测定了丁香酚对烟草花叶病毒外壳蛋白体外聚合的影响。[结果]丁香酚对烟草花叶病毒病具有较好的预防和治疗效果;丁香酚与病毒混合处理后,病毒粒子有断裂现象;丁香酚对TMV外壳蛋白体外聚合有一定的抑制作用。[结论]丁香酚可以作为新型抗病毒剂用于防治作物病毒病。[Aims] The aim of this research was to study mode of action of eugenol on tobacco mosaic virus disease. [Methods] The preventive and therapeutic effect of Eugenol on tobacco mosaic virus disease was determined. The influence of eugenol on TMV virions was observed with electron microscope. The effect of ugenol on polymerization of TMV coat protein was also determined. [Results] The results showed that eugenol had a better preventive and therapeutic effect. The TMV virions treated with Eugenol showed ruptures and abnormality. Eugenol had an inhibition effect on polymerization of TMV coat protein. [Conclusions] Eugenol as a newly reported antiviral compound could be used to control plant virus diseases.
