菊花切花的生产量在整个切花生产中占比例最大,高达30%,它是世界上栽培最普遍、销售量最大的花卉之一。能侵染菊花的病毒多达近二十种。因此,只有搞清中国菊花上病毒的种类、分布,病毒的检疫、检测及无毒种苗的生产才能顺利进行。我们采用乳胶凝聚、免疫电镜、免疫双扩散、ELISA、双向电泳等方法来鉴定菊花切花病毒的种类。现已鉴定出菊花上有蕃茄不孕病毒菊花株系(CB株系) (Tomato Chrysanthemum cut flower production in the entire cut flower production accounted for the largest, up to 30%, it is the world’s most common cultivation, one of the largest sales of flowers. Up to nearly 20 kinds of viruses that can infect chrysanthemum. Therefore, only to find out the Chinese chrysanthemum species, distribution, virus quarantine, testing and production of non-toxic seedlings in order to proceed smoothly. We use latex agglutination, immunoelectron microscopy, double immunodiffusion, ELISA, two-dimensional electrophoresis and other methods to identify Chrysanthemum species. Chrysanthemum has been identified with tomato infertility virus chrysanthemum line (CB strain) (Tomato
