摘要
对陕西省桃主产区的病毒病发生情况进行了调查和ＥＬＩＳＡ检测。查明了李属坏死环斑病毒（ＰＮＲＳＶ）、李矮缩病毒（ＰＤＶ）、苹果褪绿叶斑病毒（ＣＬＳＶ）、桃潜隐花叶类病毒（ＰＬＭＶｄ）和桃耳突病毒（ＰＥＶ）等５种病毒和类病毒在桃上的存在及感染情况。ＥＬＩＳＡ检测结果表明，ＰＮＲＳＶ的感染率最高，ＣＬＳＶ发生也较普遍，ＰＤＶ感染率较少，各种病毒的混合感染都有出现，ＰＮＲＳＶ、ＰＤＶ和ＣＬＳＶ的总感染率达６５．８％。ＰＬＭＶｄ和ＰＥＶ的田间发病率约为１．０％和０．２％。
Peach ( P. persica ) trees in the major production areas of Shaanxi were surveyed and detected for viruses by ELISA. 5 different viruses and viroid have been identified in peach : prunus necrotic ringspot virus (PNRSV), prune dwarf virus (PDV), apple chlorotic leafspot virus (CLSV), peach latent mosaic viroid (PLMVd) and peach enation virus (PEV). The incidence of PNRSV infection is the highest, CLSV infection is common, PDV infection is low, different virus mixed infection occurred, 65.8% of the trees were found to be infected with one or more viruses when the samples were detected by ELISA, PLMVd and PEV being found in the field are 1.0% and 0.2%.
