罗汉果病害研究进展

Diseases of Siraitia grosvenorii(Swingle)C. Jeffrey ex A M Lu & Zhi Y Zhang: A review

  • 摘要: 罗汉果是广西大宗道地药材,具有润肺止咳的功效,其所含低热量的罗汉果甜苷备受人们欢迎。随着罗汉果人工种植面积的不断扩大,其病害问题日益突出,质量和产量均受到严重影响,已成为制约罗汉果产业发展的重要因素之一。目前已报道的罗汉果病害有罗汉果病毒病、根结线虫病、青枯病、斑枯病、芽枯病、炭疽病、白绢病和根腐病等,其中病毒病和根结线虫病是主要病害,发生普遍、危害性大。文章综述了罗汉果病害的发病症状、病原、发生规律及防治方法等研究现状,指出当前罗汉果病害研究主要聚焦于罗汉果病毒病和根结线虫病,但研究深度不够,生产中罗汉果病毒病和根结线虫病问题依然严峻;提出建立快速、简便、特异性强的罗汉果病毒病检测方法,制定和完善罗汉果病毒检测规程;完善罗汉果脱毒苗生产技术体系,做到组培苗不带病毒,育苗基质不带线虫;重视田间综合防治技术协同研究,以减少病毒和线虫传播;加强对罗汉果病毒病和根结线虫病防治的宣传,指导农户科学合理种植;加强罗汉果抗病毒和抗线虫种质资源的收集、筛选与利用。针对今后罗汉果病害重点研究方向,认为应系统开展“寄主、病原物、环境”三角互作关系研究,建立绿色防控技术体系,选育抗病品种,以期为罗汉果病害的综合防治提供参考,推动罗汉果产业的高质量发展。

     

    Abstract: Siraitia grosvenorii(Swingle)C. Jeffrey ex A M Lu & Zhi Y Zhang,as one of the genuine medicinal materials in Guangxi,has high medicinal and edible values. The dried fruit of S. grosvenorii has a remarkable effect on moistening the lungs and relieving cough. As one of the effective components of S. grosvenorii, mogroside is not only high in sweetness,but also low in calories,which makes it very popular. With the continuous expansion of planting areas,the diseases of S. grosvenorii have become one of important factors restricting its development. The reported diseases of S. grosvenorii include virus disease,root-knot disease,bacterial wilt,leaf blight,bud blight,fruit anthracnose, southern blight and root rot,among which virus disease and root-knot disease are the main diseases,which are common and harmful. This manuscript reviewed the research progress on the diseases of S. grosvenorii,including the symptoms,pathogen, occurrence rule and prevention method. At present,the researches of S. grosvenorii disease mainly focus on virus disease and root-knot disease, but the research depth is not enough, so the virus and root-knot diseases are still the serious diseases in production. It is suggested to establish a rapid,simple and specific method for the detection of S. grosvenorii virus diseases, and formulate and improve the detection procedure of the virus disease, improve the production technology system of virus-free seedlings of S. grosvenorii,so that the tissue culture seedlings would be free of viruses and the seedling substrate is free of nematodes; reduce the transmission of virus and nematodeby attaching importance to the collaborative research of field integrated control technology; strengthen publicity on the prevention and control of S. grosvenorii virus disease and root-knot disease,and guide farmers to plant scientifically and rationally;strengthen the collection,screening and utilization of S. grosvenorii germplasm resources for antiviral and nematode resistance. It is suggested to focus on the research on the interaction of host,pathogen and environment,establish a green prevention and control technology system, and select disease resistant varieties,so as to provide a reference for the comprehensive control of S. grosvenorii diseases and promote the high-quality development of S. grosvenorii industry.
