That reduced tobacco leaf usability in cigarette manufacture. For decreasing nicotine content, harmonizing chemical contents and improving tobacco leaf usability, 54 different kinds of chemical materials were used to treat van K326 plants, a variety of flue-cured tobacco.
为降低烤烟烟碱含量、协调烟叶化学成分、提高其工业可用性,本研究以烤烟品种K326为材料,期望从54个不同化学物质的处理中筛选出既可降低烟碱含量,又不影响烟叶生长发育、产量、品质的处理,然后探讨所筛选出的处理应用于生产的配套栽培技术;通过比较烟碱含量存在显著差异的处理间烟碱合成的前体物质、中间产物含量以及合成酶活性间的差异,探讨不同化学物质处理对烟碱生物合成、积累的调控机制。
