黄瓜病毒病又叫黄瓜花叶病,在各蔬菜产区均有发生,是黄瓜生产中极其重要的一种常见性病害,在黄瓜生长过程中可单独或复合侵染引起危害。不同年份以及不同地区之间发生程度有所差异,春季保护地栽培和秋季露地栽培黄瓜发生较重,病株率达30%以上,对黄瓜产量和品质均有明显影响。发病原因:黄瓜病毒病主要由颗粒状的黄瓜花叶病毒(图1)、甜瓜花叶病毒和杆状RNA类的烟草花叶病毒(图2)等三种病毒引起。黄瓜花叶病毒有很宽的寄主范围,可侵染1000多种双子叶和单子叶植物。甜瓜
Cucumber virus disease, also known as cucumber mosaic disease, occurs in all vegetable producing areas. It is an extremely important common disease in cucumber production. It can cause harm in cucumber growth alone or in combination. In different years and in different regions, the degree of occurrence was different. The cultivated cucumbers in spring and autumn were heavier and the diseased plants rate was more than 30%, which obviously affected the yield and quality of cucumber. The cause of the disease: Cucumber virus disease is mainly caused by three kinds of virus such as granular cucumber mosaic virus (Figure 1), melon mosaic virus and rod-shaped RNA tobacco mosaic virus (Figure 2). Cucumber mosaic virus has a wide host range and can infect more than 1,000 species of dicotyledonous and monocotyledonous plants. melon
