植物病毒病的鉴定,通常采用汁接液种试验,用病毒抗血清进行血清试验,在电镜下观察病毒粒子的形态等。但汁液接种只限于少数测试植物,而且需除虫和消毒土壤、育苗管理等等,很费功夫;血清试验可同时处理多种样品,具有能在短时间内检出病毒及含量的优点,但也能利用有共同抗原的病毒;电镜观察需要熟练有关技术,其适合观察棒状、线条状、杆状等较大型病毒颗粒;然而,对小球形病毒的鉴定中,由于不易识 Identification of plant virus disease, the juice is usually used liquid-type test, serum test with virus antiserum, the virus morphology observed under electron microscopy. However, the inoculation of juices is limited to a few test plants, and it requires time to exterminate and disinfect the soil, nursery management, etc. Serum tests can simultaneously treat a wide range of samples and have the advantage of detecting viruses and contents in a short period of time. However, But also can use viruses with common antigens. Electron microscopy requires skilled techniques that are suitable for observing larger virus particles such as rods, lines, rods, etc. However, in the identification of small spherical viruses,
