马铃薯病毒危害既能引起系统性侵染,又能一直保留在活株营养部分。马铃薯为块茎繁殖作物,一旦植株感染病毒,块茎世代传递,逐年增殖蔓延和积累,造成愈来愈严重的后果。马铃薯卷叶和皱缩花叶是生产上存在的两种主要退化类型,分别由卷叶病毒和X、Y病毒感染造成。卷叶病毒和皱缩花叶 Potato virus damage both cause systemic infection, but also has been retained in the live nutrition part. Potato is a tuber propagating crop. Once the plant is infected with virus and the tubers are passed on from generation to generation, its proliferation and accumulation gradually increase and cause more and more serious consequences. The curly leaf and the crimped leaf are the two main degenerative types of production, caused by the leafroll virus and the X, Y virus respectively. Leaf curl virus and crimped mosaic
