| 摘 要： | 从植物天然产物中开发防治烟草花叶病毒病的药剂是目前的发展方向.对4种具有抗烟草花叶病毒病(TMV)作用的植物提取物进行了大田防效对比试验,结果表明:1、2号药剂对于TMV具有显著有效的直接抑制作用,2号药剂还具有一定的抗TMV诱导作用,稀释1 000倍的2号药剂抗普通烟草花叶病效果防效可高达82.99%.2号和4号药剂对烟草普通花叶病防治作用均显著超过了病毒A药剂.

| Abstract: | Exploitation of natural plant extracts against TMV of tobacco is a new direction for development of antivirus. Comparative experiments about field antiverus effects were carried out with 4 natural plant extracts which were found having resistance against TMV of tobacco in laboratory. The results suggested that No.1 and 2 reagents possessed prominent restraining ability to TMV, and No.2 reagent also provided with certain inductivity against TMV: 1000 times dilution of No.2 reagent still had high antivirus ef... |
