摘要
广东的开平金山火蒜、信宜木蒜、怀集绵蒜、怀集火蒜、高州火蒜、台山大蒜及河南大蒜等七个栽培品种看来都已100％感染了大蒜花叶病毒。典型的症状为花叶、扭曲、黄色条斑及矮缩等。病毒可由汁液传播,除大蒜外,人工接种的35种寄主植物全部不发病。电镜观察到开平金山火蒜等七个品种的病株汁液均含有二种线状病毒粒体,大小分别为12—13×500—700nm和12×900—2000nm,和一种大小为14×200—300nm的棒状病毒粒体。对开平金山火蒜病毒粗提纯液进行了病毒粒体在葡聚糖凝胶洗脱检测和蛋白外壳分子量测定,结果也都表明存在有三种病毒粒体。病叶切片电镜观察到细胞质内有环状和风轮状内含体。开平金山火蒜病毒抗血清与其它六个品种的抗原病毒具有同一血清反应,与水仙花叶病毒、TMV、马铃薯病毒X、Y和S、西瓜花叶病毒株系2和番木瓜环斑病毒均无反应。金山火蒜病毒中长度为500—700nm的粒体与加拿大大蒜花叶病毒粒体大小相同,其交互血清反应均为阳性,表明它们属同一种病毒,同为马铃薯Y组的大蒜花叶病毒(GMV)。其他两种病毒的归属有待进一步研究解决。

Abstract
Seven garlic cultivars in Guangdong province were found 100％ infected by mosaic disease. The infected garlics showed typical symptoms of mosaic,yellowstreak, curly-top and dwarf. The viruses were transmissible from garlic to garlic by juice, but other 35 tested plant species were found insusceptibleTwo kinds of flexible virus particles with the sizes of 12-13×500-700 nm and 12×900-2000nm respectively,one kind of rod-shaped particle with the size of 14×200-300nm, and a kind of pinwheel inclusion existing in ...
