中文摘要:
      为探究云南植烟区域对烤后硃砂烟叶质量的影响,运用统计性描述、主成分分析和聚类分析探讨了不同植烟区域硃砂烟叶外观质量和理化特性差异。结果表明,硃砂烟中部烟叶颜色和色度、上部烟叶外观质量指标受植烟区域的影响较大;中上部烟叶平衡含水率相对稳定,但叶面密度波动较大,其变异系数CV值分别为17.05%和20.52%;植烟区域对中上部烟叶化学成分也有较大影响,尤其是烟碱、新烟碱、假木贼碱和氯含量差异较大,其CV值高达32.89%~97.29%;主成分和聚类分析发现,滇中植烟区中上部外观质量、中部理化特性与其它烟区存在明显差异,表明滇中植烟区的中部硃砂烟叶具有明显区域特色。
英文摘要:
      To explore the effects of various tobacco planting regions on the quality of cherry red tobacco leaves in Yunnan, the differences in appearance quality and physicochemical properties were analyzed by statistical description, principal component analysis and cluster analysis in different tobacco planting regions. The results showed that the planting regions were involved huge influences on the color and color intensity of medium leaves and the appearance of upper leaves.The equilibrium moisture content of middle and upper tobacco leaves was relatively stable, but the leaf density fluctuated greatly, and the coefficient of variation(CV) was 17.05% and 20.52%, respectively.The planting regions also affect the chemical property of upper and middle leaves greatly,with the greatest impact on the contents of nicotine, neonicotinoid, pseudopyrine and chlorine, and the CV was up to 32.89%~97.29%. The results of principal component and cluster analysis showed that the appearance quality of middle and upper leaves and physicochemical properties of middle leaves in central Yunnan were significantly different from those in other planting regions, indicating that cherry red tobacco leaves in central Yunnan had obvious regional characteristics.
