| 摘 要： | 对早花烟草驳枝后，其成熟期间中部和上部叶中叶绿素（Ch1）含量和硝酸还原酶（NR）活性下降，下部叶则增高，成熟后期的上部叶中淀粉酶（AM）活性明显增强。经驳枝的烟草，中、上部叶烘烤后叶中淀粉、氮和烟碱含量下降，下部叶中的淀粉含量无明显变化。 |

| Abstract: | The early-flowering tobacco was treated with branching-after-topping.The results showed that the chlorophyll(Chl)content and nitrate reductase(NR)activity in upper and middle leaves decreased,amylase(AM)activity at later ripening period increased;NR activity in lower leaves decreased.After branching-after-topping starch,N and nicotine contents decreased in upper and middle leaves,starch content was not affected in lower leaves. |
| Keywords: | early-flowering tobacco branching-after-topping chlorophyll nitrate reductase amylase |
