摘 要:为了防治烟草普通花叶病,研究了不同类型制剂对感染烟草花叶病毒(TMV)烟叶的活性氧含量、活性氧清除率及抗氧化率的影响。结果表明,同正常叶片相比,感染TMV烟叶的O2-·、·OH、H2O2含量升高,而活性氧清除率及抗氧化率下降,施用不同制剂后,烟叶的活性氧含量降低,清除率及抗氧化率升高。与受害对照相比,喷施中草药配伍制剂处理20d时,烟叶中的O2-·、·OH、H2O2含量分别降低了67.5%、60.0%、57.5%,O2-·、·OH清除率及抗氧化率分别提高了57.3%、57.2%、75.6%。喷施制剂能降低感染TMV烟叶的活性氧含量,其中中草药配伍制剂效果好于化学制剂和抗生素试剂,并且制剂的预防效果优于治疗效果。With purpose to prevent and offer treatment to tobacco mosaic virus(TMV),a research has been conducted for the possible influence of a variety of preparations on the active oxygen content,clearance ratio of active oxygen and antioxidant rate of tobacco leaves with infection of TMV. Findings indicated that the content of O2- , OH and H2O2 in the TMV-infected tobacco leaves surged while the clearance ratio of active oxygen and antioxidant rate declined,if compared to the healthy leaves. Following the treatment of different preparations, the active oxygen content went down with the climbing clearance ratio and antioxidant rate. Contrasted to the harmed, theO2-, OH and H2O2 content of leaves fell by 67.5% ,60.00%0 and 57.5% respectively whilst the clearance ratio of 02-, OH and the antioxidant rate for them conversely went up by 57.3%, 57.2% and 75.6% respectively when the preparations with Chinese herbal medicine were applied. Offering the treatment of preparations can effectively reduce the active oxygen content of the TMV-infected tobacco leaves. And among all these preparations, the Chinese-herbal-medicine ones, which focus the attention on the function of prevention rather than cure, are more effective than the chemical and antibiotic preparations.
