| 摘 要： | 由山东济南和泰安两市郊区大面积受害的莴苣(Lactuca sativa L.var.asparagina L.)上分离到一株病毒。莴苣上症状为系统花叶,畸型和褐色斑点。人工接种,在昆诺阿藜和苋色藜上产生局部枯斑和系统症状,千日红上呈不规则斑块,不侵染普通烟、心叶烟、曼陀罗、豇豆、菜豆和黄瓜。传毒试验证明经汁液和蚜虫传播,种子带毒。病毒稀释限点5×10-1~5×10-2;失活温度55~60℃;体外保毒期(22~23℃)24小时,经有机溶剂澄清,聚乙二醇沉淀和差速离心可部分提纯。病毒粒子线状,长约750毫微米;病组织超薄切片可见风轮状内含体。试管沉淀法初步测定与马铃薯Y病毒血清呈阳性反应。
