樱草(Primula obconica),又称报春花,是早春季节人们喜爱的一种花卉。近年来,患病严重,病株的叶片呈现花叶、畸型、翻卷等症状,影响观赏。关于樱草花叶病毒在国内未见报道。本文简要报道樱草花叶病毒的分离与鉴定(以下简称PMV)。
A sphere-shaped virus has been found from the diseased plant of primula. Fifteen species plants of seven families were infected, but other three of two families tested were not.The virus purified by PEG(M.W.6000)precipitation and differential centrifugation is found to have a diameter of the isometric particle with 28—32 nm by UV absorption spectrum scanning, the value of A_(260)/A_(280) is 1.70.On the hasis of the symptomes in different host plants, morphological structure of the virions, serological test, we preliminarily conclude that the virus is a strain of the cucumber mosaic virus.
