摘要: 通过对随机采自陕西省辣椒主产区关中地区的4批137份辣椒叶样的免疫电镜观察和ELISA分析,发现关中西部地区辣椒前期(6月份)病毒病的主要病原为CMV和BBWV,后期(即成株期)主要病原为PMMV、BBWV、CMV、ToMV等;整个关中地区辣椒病毒病的4种主要病原依次为BBWV、CMV、CVMV和PMMV,渭南市、兴平市的主要病原为BBWV,眉县的主要病原为BBWV和PMMV,岐山县的主要病原为BBWV和CMV。各年份间主要病原的侵染频率有所不同。

Abstract: By means of immunoelectronmicroscopy and ELISA, 137 pepper leaf samples collected from the Guanzhong area of Shaanxi Province were analyzed. The results showed that, in west part of Guanzhong area, the major viruses infecting pepper are CMV and BBWV at seedling stage, and are PMMV, BBWV, CMV, and ToMV etc. in mature period. In the Guanzhong area of Shaanxi Province, the major viruses infecting pepper in mature period are BBWV, CMV, CVMV, and PMMV. In mature period, the results of 4 representative places are as follows: the major virus infecting pepper in the Weinan and Xingping cities is BBWV; the major virus infecting pepper in Meixian county is BBWV and PMMV; the major virus infecting pepper in Qishan county is BBWV and CMV. The results also indicated that the infecting frequency of major viruses is various with different years.
