1.辣椒花叶病 主要由烟草花叶病毒(TMV)和黄瓜花叶病毒(CMV)侵染所致。烟草花叶病毒使株矮,脱叶,出现黄斑块花叶。鉴定方法是用病叶榨汁接种到指示植物——心叶烟的叶面,会产生小褐枯斑;接种普通烟苗产生花叶。电镜下病毒粒子呈直杆状。用抗TMV抗血清与病叶汁液作用有沉淀反应。黄瓜花叶病毒使顶叶簇生,变成细条的蕨叶状。鉴定方法是用此病叶汁摩擦接种指示植物——蚕豆的叶面,会产生枯斑;接种苋色藜叶面有小枯斑。电镜下病毒粒子很小,呈球状。用抗GMV抗血清与病叶汁液作用有沉淀反应。
1. Pepper mosaic disease is mainly caused by the infection of TMV and CMV. Tobacco mosaic virus makes plant short, defoliate, appear macular mosaic. Identification method is to diseased leaves of jujube inoculated to indicate the plant - leaflet leaves, will produce small brown spots; inoculation of ordinary tobacco seedlings. Under electron microscope, the virion was straight rod. With anti-TMV antiserum and sick leaves juice precipitation reaction. Cucumber mosaic virus parietal parietal, into a thin fern leaf. Identification method is to use this diseased leaf juice friction inoculation indicated that the plant - broad bean foliage, will have a spot; inoculated amaranth leaves have small dead spots. Electron microscope virus particles are small, spherical. With anti-GMV antisera and diseased leaves juice precipitation reaction.
