| 摘 要： | 对结瘤烟草植株的根、茎、叶各部位主要化学成分的含量进行了测定。结果表明：结瘤烟草的烟碱含量以叶为最多，根次之，而茎最少；总糖、总氮和蛋白质的含量则以叶为最多，茎其次，根最少。烟草结瘤后，除总氮和蛋白质的含量在根内有所增加外，其余成分在根、茎和叶中的含量与对照植株相比均呈下降趋势。

| Abstract: | In the nodulated plants of tobacco, nicotine content was found to vary with organs, with the highest content in the leaves, followed by the roots and the stem. The contents of total sugar, total nitrogen and protein were the highest in the leaves, followed by the stem and the roots. As compared with the non-nodulated control, total nitrogen and protein somewhat increased in the roots of the nodulated plants and other chemical components declined in the roots, the stem and the leaves. |
