| 摘 要： | 采用化学诱导的方法进行烟草对花叶病毒的诱导抗性的试验研究。发现用Ｓ３０和Ｌ１两种诱抗剂均能在烤烟，白肋烟和心叶烟上诱导出对ＴＭＶ的抗性。诱抗效应达１９．１％－３５．６％。此外，诱抗后心叶烟，白肋烟还表现出枯斑反应提前和枯斑缩小等抗性增强反应。将诱抗材料子代接种ＴＭＶ，证明有诱抗性传递现象，其传递效应为２５．２％－４２．６％。经连续三代用Ｌ１诱抗剂在同一烤烟品种（Ｇ１４０）的苗期和花期分别诱导，其子

| Abstract: | A series of experiments was carried out on the induced resistance of tobacco to TMV. Using the S30 and L1, the resistance to TMV had been induced on the cure tobacco (NC 89, G140), white burley tobacco (N. tabacum), and N. glutinosa (the rate: 19.5%-35.6%). N. glutinosa and white burley tobacco could react to necrosis in earler period and narrow the necrotic spot. The progenies of induced tobacco plant remained to express a higher resistance (the rate: 25.2%-42.6%). Through inducing the resistance in the same variety of tobacco (G140) for three generations with L1 at seedling and flowering stages, the resistance in the progenies would increase generation by generation. The induced resistance rates were of F1, F2 and F3 16.98%, 27.94% and 36.42%, respectively. |
