摘要
试验以湖南郴州烟区所产云烟87品种中部叶为试验材料,对密集烘烤过程中烟叶含水量及形态参数的变化进行测量,通过相关性和回归分析探究烘烤过程中烟叶水分含量与形态变化之间的关系。结果表明:全叶、叶片和主脉含水量与横向、纵向和叶面积收缩率以及横向卷曲度、主脉体积5项形态指标均呈显著或极显著负相关,全叶和叶片含水量与纵向卷曲度、主脉厚度及叶片体积呈显著或极显著负相关关系,叶片厚度与烟叶各项含水量指标的相关性均未达到显著水平;回归分析结果表明,烟叶含水量与各项形态参数的拟合程度较好,均达到极显著或显著水平,说明可依据烟叶形态变化判断烘烤过程中叶片、主脉和全叶的含水量。
The middle leaves of Yunyan 87 planted in Chenzhou tobacco growing area of Hunan province were used as test materials, the moisture content and morphological parameters of tobacco leaves during bulk curing process were measured, and the relationship between moisture content and morphological changes were studied through correlation and regression analysis. The results showed that the water content of the whole leaf, leaf and main vein had significant or very significant negative con＇elations with the 5 morphological indexes of vertical shrinkage, horizontal shrinkage, area shrinkage, transverse curvature and main vein volume. The water content of whole leaf and leaf had a significant or very significant negative con＇elation with vertical rolling, main vein thickness and leaf volume. The correlation between leaf thickness and moisture content of tobacco leaves did not reach a significant level. The results of regression analysis showed that the water content of tobacco leaves was well fitted with all moqohological parameters, reaching a very significant or significant level, indicating that the moisture content of leaves, main veins and whole leaves could be judged according to the morphological changes.
