摘　　要：1989年在郑州郊区对番茄病毒病进行了调查,平均病株率为36.4%,最高达50%以上,平均病情指数为19.4,最高达30以上。症状以花叶为主,占60.4%,条斑和蕨叶并重,分别占16.8%和16.5%,其它症状占6.3%。毒源种类鉴定结果表明,春番茄上主要毒源种类是TMV、CMV,分别占46.5%和38.0%;其次为二者复合侵染,占8.0%;还有PVX,占3.0%;未检出病毒的样品占6.5%。秋番茄主要毒源为CMV,占40.0%;其次为TMV 和TMV 与CMV 复合侵染,二者均占28.0%,未检出病毒的样品占4.0%。引起番茄3种主要症状的病毒种类不同,花叶型主要由TMV 或CMV 单独侵染,分别占47.2%和44.0%。蕨叶型主要由CMV 单独侵染,占63.2%。条斑型主要由TMV 和CMV 复合侵染,占50.0%,TMV 单独侵染占32.8%。An investigation of tomato virus diseases in the region of Zheng-zhou was conducted in 1989.The average rate of diseased plants was 36.4%,the highest 50%;the average disease index was 19.4%,the highest 30.Leaf-mosaic was the main symptom,averaging 60.4——streak accounted for16.8% and leaf-narrowing 16.5%.Among the 200 spring tomato samples ex-amined,TMV and CMV infected plants accounted for 44% and 38.5%,PVXinfected plants 3%,complex infection of TMV and CMV 8%.Among the100 autumn tomato samples examined TMV and CMV infected plants account-ed for 28% and 40%,complex infection of TMV and CMV 28%.Pathogens in-ducing 3 main symptoms of spring and autumn tomato were different.Mosa-ic type was caused mostly by TMV accounting for 47.2% and CMV 44% andcomplex infection of TMV and CMV 4.4%.Leaf-narrowing type was causedmostly by CMV alone accounting for 63.2%;streak caused by complex infect-ion of TMV and CMV amounted to 50%.
