| 摘 要： | 为查明海南省万宁市由槟榔隐症病毒1（Areca palm velarivirus 1, APV1）引起的槟榔黄叶病毒病发生情况,2020年9—11月,对该市13个乡镇（区）的黄化槟榔园进行调查、采样,共采集槟榔叶片1454份。利用RT-PCR技术对所采集样品进行了APV1检测,并对携带病毒的槟榔叶片症状进行归类整理。结果显示,由APV1引起的槟榔病毒病发生普遍,最低检出率为75%,最高检出率最达100%;进一步研究发现,感染APV1的槟榔叶片症状主要有6种类型。本研究结果可为万宁市槟榔病毒病的识别与防控提供依据。

| Abstract: | The objectives of this study is to investigate the occurrence of areca plan leaf yellowing virus disease caused by Areca palm velarivirus 1 (APV1) in Wangning, Hannan, China. During September to November 2020, all betel palm planting areas from 13 towns of Wanning were investigated and a total of 1454 leaf samples were collected and further detected by the RT-PCR method. The results showed that APV1 seemed to be the dominating pathogens affecting betel palm, with a detection rate from 75% to 100%. Meanwhile, the symptoms in betel palm infected by APV1 could be grouped into six different types. The results reported in this study would provide useful insights in the identification, prevention and control of the viral disease of betel palm. |
