Abstract

This study aimed to survey the occurrence of eight grapevine viruses in commercial vineyards located in the Calchaquíes Valleys in the northwest region of Argentina. A total of 103 samples of mature canes of vines showing either none or some viral-like symptoms were randomly collected. The samples were tested by RT-PCR/PCR-based assays for the screening of the following viruses: (GFLV), (GLRaV-1, -2, -3, -4), (GVA), (GRSPaV), and (GRBV). Sixty percent of the analyzed samples showed infection with some of the analyzed viruses, except GRBV. GLRaV-3 and GFLV were the most frequent viruses, present in 34% and 21% of the positive samples, respectively. This study represents the first survey report of the presence of grapevine viruses in the region of the Calchaquíes Valleys and contributes to the knowledge to maintain the sanitary status of commercial vineyards in Argentina.

摘要

本研究旨在调查阿根廷西北部卡尔查基斯山谷商业葡萄园里八种葡萄病毒的发生情况。总共随机采集了103份表现出无病毒样症状或一些病毒样症状的成熟葡萄藤茎样本。通过基于RT-PCR/PCR的检测方法对样本进行检测，以筛查以下病毒：（扇叶病毒）、（葡萄卷叶相关病毒-1、-2、-3、-4）、（葡萄病毒A）、（葡萄茎痘病毒）和（葡萄斑点病毒）。除葡萄斑点病毒外，60%的分析样本显示感染了某些被分析的病毒。葡萄卷叶相关病毒-3和扇叶病毒是最常见的病毒，分别存在于34%和21%的阳性样本中。本研究是卡尔查基斯山谷地区葡萄病毒存在情况的首份调查报告，有助于了解如何维持阿根廷商业葡萄园的卫生状况。
