摘要
为深入了解湖南烤烟总糖含量区域特征,对湖南主产烟区烤烟的总糖含量进行了测定和统计分析。结果表明:湖南主产烟区不同部位的总糖含量是下部>中部>上部,部位间存在极显著差异,主栽的品种之间总糖含量在统计学上不存在显著差异,但年度之间总糖含量存在极显著的差异。湖南烤烟上、中部烟叶总糖含量在地区间、生态区域间差异显著,但下部烟叶差异不显著。聚类分析将湖南烤烟总糖含量大体可分为低总糖区、上中部烟叶高总糖区、下部烟叶高总糖区三大类型。湖南烤烟总糖含量不同部位的空间分布存在一定差异。
Total sugar content of flue-cured tobacco from production areas in Hunan province were determined and statistically analyzed in order to understand roundly regional character of total sugar.The results showed that the sequence of total sugar contents：X2F〉C3F〉B2F.There was extremely significant difference in the total sugar content of flue-cured tobacco among stalk positions and among years and not significant difference among breeds.There was significant difference in total sugar content of flue-cured tobacco among administrative areas and ecological regions in B2F and C3F and not significant difference in X2F. The cluster analysis could classify Hunan production area of flue-cured tobacco into three types in total sugar content in general. The space distribution of total sugar content of flue-cured tobacco in different grades existed partial difference in Hunan.
