基于同异反态势排序的河南烤烟化学成分指标评价

Evaluation of Chemical Composition Index of Flue-cured Tobacco Grown in Henan Province with Similarity,Difference and Counter Tendency Sequence

为了通过常规化学成分分析结果恰当评价烟叶内在品质 ,采用集对分析的同异反态势排序法对 2 0 0 1年河南 8个烟区 2 8种C3F烟叶的 6种主要化学成分进行了分析评价。结果表明 ,这 6项化学成分指标值的优劣排序为 :烟碱 >氯 >还原糖 >氧化钾 >淀粉和总氮。结论是这些C3F烟叶的烟碱、氯和还原糖含量与优质烟标准较接近 ,氧化钾、淀粉和总氮含量相差较大 ,需要采取有关的生产和加工措施进行控制。

In order to evaluate the smoking quality of flue-cured tobacco by its routine chemical compositions,the contents of six major chemical compositions,including nicotine,reducing sugar,total nitrogen,potassium oxide,starch and chlorine,in 28 kinds of flue-cured tobacco C3F grown in Henan in 2001 were set pair analyzed by similarity,difference and counter tendency sequence.The results showed that the six major chemical compositions in order of merits were:nicotine,chlorine,reducing sugar,potassium oxide,starch and total nitrogen.It was concluded that the contents of nicotine,chlorine and reducing sugar in these leaves were close to those in quality flue-cured tobacco leaves,while the contents of potassium oxide,starch and total nitrogen in C3F leaves were quite different from quality tobacco leaves,and should be regulated through proper cultural practice and processing technology.
