摘要:
西番莲病毒病在福建省西番莲主要种植区普遍发生。但品种间发病率存在差异,杂交种的发病率明显高于“本地种”。罹病西番莲在田间主要表现为叶片产生环斑、皱缩、花叶等病状。从罹病西番莲分离得到2个病毒分离物,根据它们的寄主范围、病状,物理性质,蚜传结果,血清学性质,病毒粒体形态,认为该2个病毒分离物属于黄瓜花叶病毒的2个株系,即CMV菠菜株系、CMV普通病系。
Abstract:
Virus diseases occurred widely in the main growing areas of passion fruit in Fujian province. However, the rate of infection in the field varied from variety to variety. The rate of infection of hybrid varieties was higher than that of "local" ones. It was observed in field that the infected plants had shown ringspot, mosaic and distortion of the leaves and dieback on branch.Tests were carried out to determine the identity of the causal virus strains. Two virus isolates were obtained from the infected pssionfruit growing in fruit garden of Fruit Research Institute at FAAC. Two virus isolates were identified as two strains of cucumber mosaic virus, i, e. the common and the spinach strains, on the basis of host ranges and their symptons. physical properties, transmission via aphid, serology and particle morphology.Among the causal agents of virus diseases of passionfruit in Fujian province, CMV was considered as an important one.
