摘要
接种测定结果表明：香蕉、粉芭蕉和大蕉等是香蕉束顶病毒的寄主，但美人蕉、芋头、艳山姜、芭蕉芋、姜黄、长春花、甜瓜等其它２４种供试植物不是该病毒的寄主。研究结果还认为：在福建省香蕉产区，香蕉束顶病流行的主要侵染源为香蕉病株，而粉芭蕉和大蕉等病株则可在病区中病害的长期定殖和流行起重要的作用。本文还讨论了这些研究结果对该病害的流行学和防治的重要性。
Inoculation tests showed that a Fujian isolate of the banana bunchy top virus could infect various bananas including Musa nana (Xiangjiao), M.paradisiaca (Fenjiao) and M.sapientum (Dajiao),however,it could not infect 24 other plants tested at the same inoculation pressure.These plants were Canna indica,Colocasia esculenta,Achasma zerwbet,Canna edulis,Curcuma domestica,Catharanthus roseus and Cucumis melo etc.,some of which were previously doubted to be hosts of BBTV.Virus from infected Xiangjiao cultivars was the major source of the disease epidemics in Fujian,China,whereas infected plants of Fenjiao and Dajiao could have a long term effect on the habitation of the disease in a given area.The significance of the present results on the epidemiology and control of the disease was also discussed.
