摘　　要：为研究烤烟烟碱含量与物理性状的的定量关系,对湖南浓香型烟区烤烟样本的烟碱和物理性状进行检测鉴定,并对烟碱与各项物理性状进行回归分析。结果表明:各项指标中变异系数从大到小排序为:烟碱>单叶重=叶质重>叶厚>叶宽=开片度>含梗率=平衡含水率>叶长;单叶重、叶厚、叶质重与烟碱含量呈显著正相关;开片度、平衡含水率与烟碱含量呈显著负相关;叶长与烟碱含量可用二次函数y=-49.2917x2+1.5595x-49.2917来描述,且达显著水平;叶宽、含梗率对烟碱的影响较小。该研究结果为丰富烟质量评价理论及湖南浓香型优质烟叶开发提供参考。To quantity the relationships between nicotine and physical characteristics of flue-cured tobacco,nicotine and physical characteristics of flue-cured samples grown in different area of Hunan Province were tested,regression analysis were used to analyze the correlation between nicotine and every physical property of flue-cured tobacco. The result showed that： The variation of all parameters was in the order of nicotine leaf weight = weight per unit area 〉thickness of leaf 〉leaf width = open tablets degree stem ratio = equilibrium moisture content 〉leaf length; Nicotine content had significant positive correlation with leaf weight,thickness of leaf,weight per unit area; Nicotine content had significant negative correlation with open tablets degree,equilibrium moisture content; The relationship could be described by quadratic equation y =- 49. 2917x2＋ 1. 5595x- 49. 2917 between nicotine content and leaf length,all above equation were significant at 5% level; Stem ratio and leaf width had small effect on nicotine. The research enriches the tobacco leaf quality evaluation theory and provides a reference to the development of the high quality tobacco leaves grown in Hunan Province.
