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(Chl)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。
The early-flowering tobacco was treated with branching-after-topping. The results showed that the chlorophyll （Ch1） 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-aftertopping starch, N and nicotine contents decreased in upper and middle leaves, starch content was not affected in lower leaves.
