1995~1996年调查表明,湖北省五峰、建始、恩施县(市)白肋烟主产区为花叶和黄花病毒病流行区。1995年花叶类型发病率为10%~90%,平均30%以上;黄化类型10%~30%,平均20%左右,蚀纹病在3县(市)零星发生。1996年各产区病害比1995年轻,以花叶病害为主。经血清鉴定明确,花叶类型病害、黄化类型病害和蚀纹病分别由黄瓜花叶病毒(CMV)、马铃薯Y病毒(PVY)和烟草花叶病毒(TMV)引起。CMV为侵染白肋烟的主要病毒。这是湖北省白肋烟病毒病调查与病毒鉴定的首次报道。
From 1995 to 1996, the survey showed that the main producing areas for Burley tobacco in Wufeng, Jianshi and Enshi (Hubei) areas of Hubei Province are endemic areas of mosaic virus and yellow fever virus. In 1995, the incidence of mosaic type was 10% -90%, with an average of over 30%. The type of yellowing was about 10% -30% with an average of about 20%. Erosion pattern occurred sporadically in 3 counties (cities). In 1996, the diseases in the producing areas were lighter than in 1995, with mosaic disease as the main factor. It is clear from the serum identification that mosaic type, yellow type and etc are caused by cucumber mosaic virus (CMV), potato virus Y (PVY) and tobacco mosaic virus (TMV), respectively. CMV is the major virus that infects burley tobacco. This is the first report of investigation and virus identification of Burley tobacco virus disease in Hubei Province.
