| 摘 要： | 研究了0．5％氨基寡糖素AS（净土灵）6．25mg/L对烟草花叶病毒（TMV）枯斑寄主心叶烟（Nicotiana glutinosa）的预防、治疗和钝化作用及其在烟草上引起的寄主体内防御酶系变化。结果表明，0．5％氨基寡糖素AS喷施24h后接种TMV，对烟草花叶病毒的预防效果为58．5％，对烟草花叶病毒侵染的治疗效果达43．6％，对烟草花叶病毒的钝化效果为11．8％。同时，0．5％氨基寡糖素AS处理可导致烟草品种K326叶片的PAL、POD、SOD活性不同程度提高，表明0．5％氨基寡糖素AS可以诱导烟草对TMV的抗性，提高烟草的免疫能力。

| Abstract: | The effect of oligosaccharins on tobacco mosaic virus (TMV) in Nicotiana glutinosa was studied, and its effect on defensive enzymes was tested. The preventing effect on TMV disease was 58.5% when oligosaccharins was applied 24 h after the inoculation of TMV. The treating effect on TMV disease by oligosaccharins was 43.6%. TMV was deactivated by oligosaccharins at a rate of 11.83%. Meanwhile, the activity of PAL, POD, SOD of tobacco K326 leaves was increased with various degrees after the treatment of oligosaccharins. It can prove that Jingtuling can induce the resistance of tobacco to TMV, thereby it can strengthen the immunity of tobacco. |
