湖南郴州烟区大田烟蚜带毒率与烟草病毒病发病相关性研究

Study on the Correlation between the Incidence of Tobacco Virus and the Belt Tox-icity Rate of Aphid in the Tobacco Area of Chenzhou Hunan

摘要: 用环介导等温扩增(LAMP)技术检测了湖南郴州烟草和蚜虫的带毒率，分析了烟蚜带毒率与烟草发病率关系。结果表明：田间烟草CMV、PVY带毒率分别为57.2%、46.4%；田间烟蚜黄瓜花叶病毒(Cucumber mosaic virus, CMV)、马铃薯Y病毒(Potato virus Y, PVY)的检出率分别为49.05%、32.12%；烟蚜带毒率与烟草病毒病发病率无显著相关性。

Abstract: The poisoned rate of tobacco and aphids in Chenzhou, Hunan, was detected by using cyclomediated isothermal amplification (LAMP) technique. The relationship between tobacco incidence and tobacco aphid incidence was analyzed. The results showed that the toxicity rates of CMV and PVY were 57.2% and 46.4% respectively. The detection rates of Cucumber mosaic virus and Potato virus Y were 49.05% and 32.12% respectively. There was no significant correlation between the incidence of tobacco virus and the incidence rate of tobacco aphid virus.
