1981年在福建漳州的水仙田中查到一种褪绿斑病株,经研究证实,其传播途径、鉴别寄主、体外抗性和病原形态等,均与国外有关水仙花叶病毒的报道基本一致。病毒以机械和鳞茎种球的方式传播。病毒致死温度55～60℃,体外存活期8～10周,稀释限点10~(-7)以上。病原病毒为线状质粒,大小为470～550×12～13nm,分散在细胞质内。 In 1981 in Zhangzhou, Fujian Narcissus field found a chlorotic spot strain, confirmed by the study, its route of transmission, identification of hosts, in vitro resistance and pathogen morphology, with foreign narcotic mosaic virus basically the same. The virus spreads mechanically and bulb bulbs. Virus lethal temperature 55 ~ 60 ℃, in vitro survival of 8 to 10 weeks, dilution limit 10 ~ (-7) or more. Pathogenic virus is a linear plasmid, the size of 470 ~ 550 × 12 ~ 13nm, dispersed in the cytoplasm.
