近年来的研究表明,大豆花叶病毒(SMV)可以在田间普遍侵染扁豆。根据南京地区扁豆病毒病的调查,SMV自然侵染扁豆的发病率可达到病株的60％以上,作者从扁豆上分离到一株SMV-DL-6,采用了鉴别寄主和单克隆抗体双抗体夹心ELISA两种方法进行毒株鉴定。 将SMV-DL-6用常规摩擦接种4个大豆品种,结果(表1)SMV-DL-6分离物不能侵 In recent years, studies have shown that soybean mosaic virus (SMV) can be widely in the field of lentils. According to the survey of lentil virus disease in Nanjing area, the incidence of naturally infected lentils in SMV can reach over 60% of the diseased plants. The author isolated a strain of SMV-DL-6 from lentils and used the differential host and monoclonal antibody diabodies Sandwich ELISA two methods for strain identification. Four soybean cultivars were inoculated with SMV-DL-6 by conventional rubbing and the results (Table 1) SMV-DL-6 isolate could not invade
