为探索烤烟物理特性与化学成分的关系，检测了92种河南烤烟样品的6项物理指标和7项常规化学成分，并进行了简单相关分析和典型相关分析．结果表明：1）填充值与总糖、还原糖呈极显著负相关，与总氮、氯呈极显著或显著正相关；叶片厚度与总植物碱、总氮、氯呈极显著正相关，与总糖、还原糖呈极显著负相关；叶面密度与总植物碱、总氮呈极显著正相关，与总糖、还原糖呈极显著负相关；阴燃时间与还原糖、氯呈极显著或显著负相关；抗张强度与总植物碱、总氮、氯呈极显著或显著负相关，与总糖呈极显著正相关；平衡含水率与总糖、还原糖呈极显著正相关，与总植物碱呈极显著负相关．典型相关分析结果与简单相关分析基本一致，相关性显著的3对典型变量间的典型相关系数分别为0．817，0．538，0．524．2）影响烤烟物理特性的常规化学成分主要有总植物碱、总糖、还原糖、总氮和氯，钾和淀粉的影响较小．

To explore the relationship between physical properties and chemical components about flue-cured tobacco,six physical properties and seven normal chemical components of 92 flue-cured tobacco sam-ples were detected and these data were analyzed by simple correlation analysis,canonical correlation analy-sis and path analysis.The results showed as follows:1)value had significant negative correlation with total sugar and reducing sugar filling,and had significant extremely positive correlation with total nitrogen and chlorine;leaf thickness had significant extremely positive correlation with total alkaloid,total nitrogen and chlorine;had significant negative correlation with total sugar and reducing sugar;leaf density had signifi-cant extremely positive correlation with total alkaloid and total nitrogen,had significant extremely negative correlation with total sugar and reducing sugar;chlorine had extremely or significant extremely negative correlation with reducing sugar and smoldering time;tensile strength had extremely or significant negative correlation with total alkaloid ,total nitrogen and chlorine,had significant extremely positive correlation with total sugar;equilibrium moisture content had significant extremely positive correlation with total sug-ar,had significant extremely positive correlation total alkaloid and reducing sugar.The results of canonical correlation analysis was consistent with the simple correlation analysis,and the canonical correlation coeffi-cients of three pairs of canonical variables were 0.817,0.538,0.524 respectively.2)Total sugar,total alkaloid,reducing sugar,total nitrogen and chloride were closely related potassium and starch less with physical characteristics in routine chemical components.
