李属坏死环斑病毒(Prunus necrotic ringspot vi-rus,PNRSV)和李矮缩病毒(Prune dwarf virus,PDV)是较为常见且危害严重的两种植物病毒,1992年被我国列为进境检疫危险性有害生物,主要危害李属和蔷薇属植物。反转录-聚合酶链式反应检测法(RT-PCR)因操作简便且灵敏度高而备受青睐。利用该方法已分别从北京怀柔[1-2]及大连地区[3]栽
Prunus necrotic ringspot virus (PNRSV) and Prune dwarf virus (PDV) are the two most common and serious plant viruses. In 1992, our country was listed as the quarantine danger Sexual pests, the main hazards Prunus and rose. Reverse transcription-polymerase chain reaction (RT-PCR) is favored for its ease of use and high sensitivity. The method has been planted separately from Beijing Huairou [1-2] and Dalian [3]
