1995年至1997年间,从山东烟区各主要产烟县(市)采集病毒样品,经鉴定、分类、分离、纯化后,对纯化物进行了生物学特性、病毒粒体形态、血清学关系等方面的比较,从而明确了山东烟区主要烟草病毒病病原物的株系:烟草黄瓜花叶病毒的普通株系(CMVc)、坏死株系(CMVTN)、黄化株系(CMVY);烟草普通花叶病毒的普通株系(TMVC)、坏死株系(TMVN)、黄化株系(TMVY)、环斑株系(TMV R0);烟草马铃薯Y病毒的普通株系(PVYO)、坏死株系(PVYN);烟草蚀纹病毒的轻症株系(TEVM)、重症株系(TEVs)。其中烟草黄瓜花叶病毒的普通株系(CMVC)、烟草普通花叶病毒的普通株系(TMVC)、烟草马铃薯Y病毒的坏死株系(PVYN)、烟草蚀纹病毒的重症株系(TEVS)是优势株系。烟草蚀纹病毒(TEV)的株系毒力分化属国内首次报道。
From 1995 to 1997, the virus samples were collected from major tobacco producing counties (cities) in Shandong tobacco area. After identification, classification, separation and purification, the biological characteristics, virus morphology and serological relationship (CMVc), necrosis (CMVTN) and yellow (CMVY) strains of tobacco cucumber mosaic virus in tobacco growing areas in Shandong Province. Tobacco common TMVC, TMVN, TMVY, TMRR; PVYO, necrotic strains of tobacco, potato virus Y, (PVYN); Tobacco Etch Virus Slight Strain (TEVM), Severe Strain (TEVs). Among them, CMVC, TMVC, PVYN and TEVS of Tobacco mosaic virus (RTVS) Is the dominant strain. Virulence of Tobacco Etch Virus (TEV) is the first reported in China.
