上海郊区草莓病毒病害表现多种症状,并日趋严重,关于草莓病毒病病原的研究,国内尚未见报道,我们将草莓病叶经氯仿和聚乙二醇处理,蔗糖梯度离心,可获得部分纯化的病毒分离物,电镜观察可见大小不同的二种球状病毒颗粒,直经分别为28—30毫微米和40毫微米左右,可能与国外报导的草莓隐潜环斑病毒(SLRV)和草莓脉暗病毒(SVBV)相似。
Strawberry virus diseases in Shanghai suburbs show a variety of symptoms and become more and more serious. There are no reports about the pathogen of strawberry virus disease in our country. We treated strawberry diseased leaves with chloroform and polyethylene glycol and sucrose gradient centrifugation to obtain partially purified Virus isolates and electron microscopy showed that the two globular virions with different sizes were 28-30 nm and 40 nm respectively, which may be related to the reported SLRV and strawberry vein dark virus (SVBV) similar.
