摘　　要：笔者纠正了“3种牡丹(芍药)病毒”的过时观点,统计、分析了国际上共计17种病毒侵染牡丹、芍药的情况,回顾了国内学者对牡丹、芍药病毒病的研究成果,包括对烟草脆裂病毒(tobacco rattle virus,TRV)侵染、为害牡丹、芍药的调查,近年来新发现的牡丹卷叶相关病毒(peony leafroll-associated virus,PLRaV)等多种侵染牡丹、芍药的新病毒,苹果茎沟病毒(apple stem grooving virus,ASGV)等已知病毒侵染牡丹、芍药的寄主新纪录,利用VIGS(virus induced gene silencing)技术研究牡丹、芍药基因功能等一系列研究。目前国内牡丹病毒病基础研究仍然存在多方面不足,如国家级课题专项资助机会少,对传统牡丹、芍药栽培中心病毒病发生本底情况不明,对病毒侵染、传播机制研究不深入等;在病毒病检测与诊断技术应用方面与西方国家相比存在明显的劣势,如基层的技术人员对病害诊断知识更新不及时,对病毒病的分子检测技术的最新发展了解不全面。由此提出应用分子检测技术开展全国范围的牡丹病毒病普查、开始牡丹病毒病的危险性分析和风险管理等有益建议。The outdated view of“three species of peony viruses”was corrected at first,whereas 17 species of viruses infecting peony(including tree peony and herbaceous peony)in the world was counted and analyzed.The research work on viral disease of peony dedicated by Chinese scholars was reviewed,including investigation about tobacco rattle virus(TRV)infecting peony;discovering several new viruses of peony such as peony leafroll-associated virus(PLRaV)and new host records for peony infected by some known virus such as apple stem grooving virus(ASGV)in recent years;a series of research progress about study on peony gene function using VIGS(virus induced gene silencing)technology.There were still many deficiencies in the basic research of peony viral disease in China,such as the lack of special funding opportunities for national projects;unknowing the background of viral disease occurrence in traditional peony cultivation centers;lacking deep research on the infection and transmission mechanism of the virus.Compared with western countries,the obvious disadvantages in the application of viral disease detection and diagnosis technology was that lower level technicians could not update the knowledge of disease diagnosis in time and could not completely understand the recent development of molecular detection technology for viral diseases.Therefore,it is suggested that molecular detection technology should be applied to carry out nationwide survey of peony viral disease,risk analysis and risk management of peony viral disease.
