摘要：

为探讨施氮量和品种对烟叶化学成分的影响，研究不同施氮水平下（6 g/株、8 g/株和10 g/株）烤烟品种‘K326’、‘云烟202’和‘云烟97’不同级别烟叶主要化学成分的变化。结果显示，不同施氮水平对C3F和X2F烟叶各化学成分的影响均达极显著水平；B2F、C3F和X2F烟叶主要化学成分在不同品种间的差异达到极显著；品种和氮水平间的交互作用极显著地影响了B2F级别烟叶的糖代谢，同时，对X2F烟叶各化学成分的影响也达到极显著水平。研究表明，氮水平和品种均能显著影响烤烟不同级别的化学成分。

Abstract:

In order to indicate the effects of different nitrogen application rate and flue-cured tobacco varieties on chemical components of tobacco leaves, the change of chemical components from different grade were studied. The results showed that the nitrogen application rate significantly affected chemical components in leaves of C3F and X2F, and chemical components in leaves of B2F, C3F and X2F were significantly affected by different flue-cured tobacco varieties. The interaction of variety and nitrogen application rate significantly affected sugar metabolism of B2F, and significantly affected chemical components in leaves of X2F. In this study, nitrogen application rate and flue-cured tobacco varieties all had remarkable effects on chemical components of tobacco leaves.
