摘　　要：为了开发一种新型、高效、绿色的烟草花叶病毒抑制剂,利用合成的壳寡糖纳米银溶液进行田间抗烟草花叶病的药效研究,结果表明,壳寡糖纳米银溶液对田间烟草花叶病的预防和治疗的效果最高分别可达67.74%,43.63%;壳寡糖纳米银溶液不仅有效地提高烟叶中性致香成分的含量,还可使烟叶常规化学成分处于较适宜的范围,从而使烟叶的品质得到改善。因此,壳寡糖纳米银溶液对田间感染烟草花叶病的烟株有一定的防治作用。In order to develop a kind of new and green inhibitor of high efficiency against tobacco mosaic, COS-Ag was used to study the effect on inducing anti-tobacco mosaic. The results showed that ： the prevention and treatment effect of COS-Ag on tobacco mosaic was up to 67.74% and 43.63% respectively in the field; COS-Ag not only effectively improved neutral aroma component,but also could make routine chemical compositions in the appropriate range, so that the quality of tobacco leaf was im- proved. Therefore,COS-Ag solution have a certain prevention effect on tobacco plants infected tobacco mosaic in the field.
