利用烟草花叶病毒普通株系（ＴＭＶ－ｏｍ）和来自新疆辣椒上的ＴＭＶ黄白卷叶株系（ＴＭＶ－ｗｙｒ）进行了比较研究。结果表明：两株系除引起辣椒和三生烟症状不同外，亦导致其他性状上的差异。ＴＭＶ－ｗｙｒ的致死温度为６０～７０℃，稀释限点１０－４～１０－５；辣椒病组织中产生大量病毒粒子的聚集体、网膜结构和分散的病毒粒子，叶绿体呈筒状；粒体大小为２５８×１６ｎｍ，ＴＭＶ－ｏｍ在辣椒病组织中只形成病毒粒子聚集体，叶绿体呈球状。辣椒酶谱分析表明：ＴＭＶ－ｏｍ接种株ＰＯＤ同工酶的活性（３条深色带）显著大于ＴＭＶ－ｗｙｒ接种株（１条深色带）。由此我们认为这些生物学性质和病生理差异可作为区分ＴＭＶ－ｗｙｒ和ＴＭＶ－ｏｍ的诊断指标。
A comparative study was conducted with TMV common lines (TMV-om) and TMV yellow-white leaf curl lines (TMV-wyr) from Xinjiang pepper. The results showed that the two strains caused different symptoms in addition to those caused by pepper and Sansheng tobacco. The lethal temperature of TMV-wyr is 60 ~ 70 ℃ and the dilution limit is 10-4 ~ 10-5. A large number of virus particles aggregates, omentum structure and dispersed virus particles are produced in capsicum, chloroplasts are cylindrical. The body size was 258 × 16 nm. TMV-om formed only aggregates of virus particles in capsicum and chloroplasts were spherical. Pepper zymogram analysis showed that the activity of POD isoenzyme of TMV-om inoculated (3 dark bands) was significantly greater than that of TMV-wyr inoculation (1 dark band). Therefore, we believe that these biological properties and physiological and pathological differences can be used as a diagnostic indicator to distinguish between TMV-wyr and TMV-om.
