【摘要】 番茄病毒病是上海市郊普遍发生的一种病害，为害日趋严重，影响产量和质量。试验结果表明，为害露地番茄的主要毒源，１９８１～１９８３年以ＴＭＶ为主，但１９８７～１９９２年已逐渐被ＣＭＶ和ＴＭＶ、ＣＭＶ混合侵集型所替代。保护地番茄病毒病亦有上升趋势。１９８１～１９８３年从番茄上获得的ＴＭＶ分离物，属Ｐｅｌｈａｍ系统的ＴＭＶ－０株系，１９８４年又发现ＴＭＶ－１．２株系。ＣＭＶ的分离物有三个株系，即ＣＭＶ番茄轻花叶株系（ＣＭＶ－ＴＭ）、ＣＭＶ番茄黄色花叶株系（ＣＭＶ－ＴＹ）和ＣＭＶ番茄重花叶株系（ＣＭＶ－ＴＳ）。其中，ＣＭＶ－ＴＳ分布较广。更多还原

【Abstract】 Tomato virus diseases are widespread in Shanghai suburbs. They become serious year after year and have a great influence upon tomato yield and fruit quality. It was shown by the authors’ experimental results that the main pathogenic cause for the open field tomato was TMV during 1981～1983, but which was substituted gradually in 1987～1992 by CMV or mixed infection of TMV+CMV, while the virus diseases in forcing culture have shown a tendency to increase. The TMV isolates obtained during 1981～1983 all belonged to the TMV strain 0 of Pelham system. In 1984 the TMV strain 1. 2 was discovered. The CMV isolates included 3 strains: mild mosaic strain (CMV-TM), yellow mosaic strain (CMVTY) and heavy mosaic strain (CMV-TS). Among them the last one is widely distributed.更多还原
