于1981年—1985年研究了黄瓜花叶病毒(CMV)对烟草花叶病毒(TMV-T)的干扰作用.用CMV向日蔡环斑花叶分离物(CMV-SRS)为诱导病毒,接种枯斑三生烟十天后,对攻击病毒TMV-T的保护率为85.6%.反之,用TMV-T为诱导病毒,接种枯斑三生烟十天后,对攻击病毒CMV-SRS的保护率为95%(70—100%)证明在CMV-SRS和TMV-T之间,有较强的相互干扰作用.含有卫星核酸的黄瓜花叶病毒CMVS51、及CM-VS52两个分离物以及CMVS51+TMVN-14(烟草花叶病毒弱株系)免疫心叶烟和枯斑三生烟十天后,对强病毒TMV-P有明显的干扰作用. 1984年证明用CMVS51及CMVS51+TMVN-14免疫心业烟十天后对TMV-P的保护率依次为67.1%、46.8%;1985年证明CMVS52、CMVS51、CMVS51+TMVN-14对TMV的保护率依次为65.5%、60.9%、54.6%,经过二年度四次试验证实CMV和TMV之间有干扰作用,并讨论了相关或不相关病毒之间的干扰作用及其在理论和应用上的意义.
The interference of cucumber mosaic virus (CMV) on Tobacco mosaic virus (TMV-T) was studied from 1981 to 1985. CMV was used to induce virus infection by CMV-SRS, The protection rate of attack virus TMV-T was 85.6% after 10 days of dead spot, and the protection rate of CMV-SRS against challenge virus was 10% after infected with TMV-T for 10 days 95% (70-100%) showed strong mutual interference between CMV-SRS and TMV-T. Cucumber mosaic virus CMVS51 containing satellite nucleic acid and two isolates of CM-VS52 and CMVS51 + TMVN -14 (weak strains of tobacco mosaic virus) immune heart leaf tobacco and dead spot after three live smoke ten days, the strong virus TMV-P have a significant interference effect. 1984 proved with CMVS51 and CMVS51 + TMVN-14 immune heart industry The protection rates of TMV-P tended to 67.1% and 46.8% after ten days. The protection rates of TMV-P against CMVS52, CMVS51 and CMVS51 + TMVN-14 in 1985 were 65.5%, 60.9% and 54.6%, respectively. The second experiment confirmed the interference between CMV and TMV, and discussed the interference between related or unrelated viruses and its significance in theory and application.
