摘　　要：【目的】分析影响潍坊烟区中部烟叶(C3F等级)感官质量的关键物理与化学指标,为进一步提高潍坊烟区中部烟叶质量提供理论依据。【方法】采用物理测量、化学检测与感官评析等方法对临朐和诸城烟区2019—2021年中部烟叶的关键物理、化学和感官质量指标进行测定。【结果】潍坊中部烟叶感官评析结果总体较好,诸城烟区中部烟叶叶长、叶宽、单叶重、叶厚度、叶面密度分别较临朐烟区高5.45%、7.31%、25.42%、15.36%和12.46%,而含梗率则低11.32%。诸城烟叶还原糖、总糖、淀粉、氮和氯等含量分别高于临朐烟区9.83%、6.23%、26.12%、7.9%和291%,而钾与钾氯比显著低于临朐烟区。感官质量与化学指标典型相关分析分别在临朐和诸城获得1对和0对典型变量,对临朐烟区典型变量影响较大的感官指标为杂气、余味、燃烧性,化学指标为两糖比、氯、钾氯比和总氮量。感官质量与物理指标进行典型相关分析分别在临朐和诸城获得1对和2对典型变量,对临朐典型变量影响较大的感官质量指标为香气量、灰色、余味量和杂气,物理指标为叶长,对诸城典型变量影响较大的感官质量指标为燃烧性、香气质和总得分,物理指标为单叶重、叶长和叶宽。对以上代表性指标进一步相关分析发现,临朐烤烟余味受烟碱含量的促进、受糖碱比的抑制,杂气受到氯含量的抑制,香气量受到叶厚与叶面密度的抑制。诸城烤烟香气质受叶片密度的促进,燃烧性受叶长、叶宽及单叶重增加的抑制。【结论】潍坊烟区中部烟叶理化指标变化显著影响其感官质量,其中具有代表性的物理指标为叶长、单叶重、叶宽,化学指标为两糖比、氯、钾氯比和氮总量,感官质量指标为杂气、余味、燃烧性、香气和灰色。建议进一步提高潍坊中部烟叶中还原糖、钾含量和糖碱比,降低诸城烟叶中的氯含量。【Objective】Analyzing the key physical and chemical indexes that affects the sensory quality of middle tobacco leaves(C3F grade)in Weifang,which can provide a certain theoretical basis for further improving the sensory quality of tobacco leaves in Weifang tobacco area.【Method】The key phenotypic,sensory and chemical parameters of the middle tobacco leaves of Linqu and Zhucheng from 2019 to 2021 were determined by physical measurement,chemical detection and sensory evaluation.【Result】The sensory evaluation of tobacco in middle leaves of Weifang was good,compared with Linqu tobacco area,the leaf length,leaf width,leaf weight,leaf thickness and leaf surface density of middle leaves in Zhucheng tobacco area was increased by 5.45%,7.31%,25.42%,15.36%and 12.46%,respectively,while the stem content was decreased by 11.32%.The content of reducing sugar,total sugar,starch,nitrogen and chlorine in Zhucheng tobacco was increased by 9.83%,6.23%,26.12%,7.9%and 291%compared to Linqu tobacco area,but the ratio of potassium to potassium chloride was significantly lower than that in Linqu tobacco area.The canonical correlation analysis of sensory quality and chemical indexes of tobacco leaves respectively obtained 1 and 0 pair canonical variables in Linqu and Zhucheng respectively,the results showed that the indexes of sensory quality which have a great influence on the canonical variables in Linqu were impurity,aftertaste and combustibility,and the chemical indexes were two-sugar ratio,chlorine content,potassium-chlorine ratio and total nitrogen content in leaves.The canonical correlation analysis of sensory evaluation and physical indexes of tobacco leaves respectively obtained 1 and 2 pair canonical variables in Linqu and Zhucheng respectively,the results showed that the indexes of sensory quality which have a great influence on the canonical variables of Linqu were aroma amount,gray amount,aftertaste amount and impurity,and the physical index was leaf length.The sensory quality which had great influence on the canoni
