我国曾报道的番茄病毒病有多种,其中最常见的是黄瓜花叶病毒(CMV)和烟草花叶病毒(TMV)引起的花叶病。柯冲等(1964)在大陆首次报道烟粉虱(Bemisia tabaci)传播的番茄病毒病——番茄黄顶病,此病在50~60年代曾在广州市郊流行,造成大面积减产。Green等(1984)报道台湾发生番茄黄曲叶病,此病与日本的番茄黄矮病(Tomato yellow dwarf)相似,并且与烟草曲叶病毒(TLCV)有血清学关系。印度、委内瑞拉等国也曾报道发生由烟粉虱传播的番茄曲叶病和番茄黄曲叶病。1991和1992年秋,在广西南宁市郊发现一种症状表现为植株矮缩,叶片向上向内卷曲,叶背面产生耳状或杯状增生物,对光看有时可见叶脉呈墨绿色,不结果或少结果的番茄病害。1992年秋广西农业科学院的番茄试验地发病率高达6.8%,对当地秋番茄生产构成了威胁。作者对病害症状、传播、血清学反应及PCR分析等方面与烟草曲叶病毒进行了比较研究,证实了该病的病原与烟草曲叶病毒有很高的同源性。现将研究结果简报如下。
There are many tomato virus diseases reported in our country. The most common ones are cucumber mosaic virus (CMV) and mosaic virus (TMV). Ke Chong et al. (1964) reported for the first time in mainland China that the tomato virus disease, tomato yellow-top disease, transmitted by Bemisia tabaci, was endemic in the suburbs of Guangzhou in the 1950s and 1960s, causing large-scale yield cuts. Green et al. (1984) reported the occurrence of tomato yellow leaf curl disease in Taiwan. The disease is similar to that of Japanese Tomato yellow dwarf and has a serological relationship with tobacco leaf curl virus (TLCV). India and Venezuela also reported the occurrence of tomato leaf curl and tomato yellow leaf curl transmitted by whiteflies. In the autumn of 1991 and the autumn of 1992, a symptom was found in the suburb of Nanning, Guangxi, which was plant dwarfing, curling upward and inward, ear or goblet accretions on the back of leaves, dark green veins were sometimes seen in light, no result or less The result of tomato disease. In the autumn of 1992, the incidence of tomato trial in Guangxi Academy of Agricultural Sciences was as high as 6.8%, posing a threat to the production of local autumn tomato. The authors compared tobacco leaf curl virus with disease symptoms, transmission, serological reaction and PCR analysis, and confirmed that the pathogen has high homology with tobacco leaf curl virus. Now the research findings are as follows.
