摘要:

为研究烤烟功能性状变化对烟碱含量的影响,以‘云烟87’为研究对象,对2018年在四川省广元烟区不同试验地随机采集的大田种植烤烟进行植物形态学和生物化学特征分析。结果表明,烟株生物量积累特征和不同分配模式对烟碱含量影响显著。其中,总生物量、根生物量、茎生物量、茎重比和比叶重越大,烟碱含量越高;烟碱含量随叶重比增大而降低。回归分析表明,茎生物量和根重比与烟碱含量变化关系密切(R2=0.91,P<0.001),比叶重和第5片叶SPAD值与烟碱含量的回归模型达极显著水平(R2=0.987,P<0.001)。基于生物量分配特征和叶功能性状特征可以较好地表征烟碱含量变化。

Abstract:

This article aims to reveal the influence of the change of functional traits on leaf nicotine content in flue-cured tobacco. Morphological and biochemical traits of ‘Yunyan 87’ were analyzed based on a field experiment carried out in Guangyuan tobacco area of Sichuan Province. Results show that distinct patterns of biomass accumulation and allocation could significantly affect the nicotine content. Briefly, plants with more total biomass, root biomass, and stem biomass as well as higher stem weight ratio and leaf mass per area have higher nicotine content. However, plants with higher leaf weight ratio have lower nicotine accumulation. In addition, regression analysis shows that the nicotine content is significantly affected by the changes of stem biomass and root weight ratio (R2=0.91, P<0.001) as well as leaf mass per area and the fifth leaf SPAD value (R2=0.987, P<0.001). It can better characterize the change of nicotine content based on the patterns of biomass allocation and the changes of functional leaf traits.

Key words: flue-cured tobacco, nicotine, functional traits, biomass allocation, ‘Yunyan 87’
