| 摘 要： | 2015年-2016年,在甘肃省10个地市24个马铃薯主栽县(区)146个生态区域(乡镇)采集了757份具有典型症状的马铃薯样品,应用DAS-ELISA法进行检测,筛查6种主要病毒(PVX、PVY、PLRV、PVA、PVS和PVM)。结果表明:631份样品检测到病毒,PVS的检出率最高,达47.03%,PVY次之,为33.82%,PVA最低,只有0.63%;发生复合侵染的病毒主要为PVY+PVS,复合侵染率达到10.13%,三种病毒复合侵染主要是PVY+PVS+PVM;病毒种类和感病程度与品种、地域有关。

| Abstract: | 757 potato samples with virus-like symptoms were collected from 146 different ecological regions (villages and towns) in 24 potato main planting counties and districts which are affiliated to 10 cities and prefectures in Gansu Province. All samples were tested for the presence of six viruses (PVX, PVY, PLRV, PVA, PVS and PVM) by DAS-ELISA in this study. A total of 631 samples were shown to be infected with virus, of which 47.03% were infected with PVS, and 33.82% with PVY. Two or three viruses were detected from some potato plants, and the combination infection of PVY and PVS was the main type with the highest infection rate of 10.13%, and the mixed-infection of PVY, PVS and PVM was the main type of infection containing three kind of virus. The type of virus and disease susceptibility were related to the potato varieties and potato growing regions. |
