酶联免疫吸附试验法从首次报道以来(Voller等,1976;Clark和Adams,1977)已被认为是鉴定马铃薯y病毒、A病毒和卷叶病毒的很有前途的方法。与标准方法相比,这一技术在灵敏和快速,特别是用常规提取法鉴定叶片中的马铃薯病毒等方面,都有其优越性。应用Pollhne滚轮榨汁器(Gugerli,1979b),一 Enzyme-linked immunosorbent assays have been considered as promising methods to identify potato y virus, A virus and leafroll virus since their first report (Voller et al., 1976; Clark and Adams, 1977). Compared with standard methods, this technique has its advantages in sensitivity and rapidity, especially in the identification of potato virus in leaves by conventional extraction methods. Application Pollhne roller juicer (Gugerli, 1979b), one
