以河南省三门峡卢氏浓香型的初烤烟叶为研究对象，进行10段分切后，研究了烟叶叶片不同区位的钾含量．结果表明：30个烟叶分切样品的钾含量在1．14％～2．39％之间，平均值为1．52％；同一片烟叶不同区位的钾含量差异性为极显著，从叶尖到叶基呈现增加的趋势；不同部位烟叶叶片钾含量存在显著差异：下部＞中部＞上部；各部位相对应的区位钾含量分布规律是：叶尖部分＜叶中部分＜叶基部分．根据这一认识，可通过聚类分析和类平均法合并小类的方法，以不同区位钾含量的差异性为评价指标，将浓香型烟叶叶片连续分为3段进行后续加工．

Using He′nan roast flavor style flue-cured tobacco leaf as research object,potassium content from different parts of tobacco leaf after cutting into 10 sections was studied.The results showed that the potassi-um content of 30 samples ranged from 1 .14% to 2.39%,which held an average value of 1 .52%.In terms of the same tobacco leaf,the potassium content of each section held significant differences,which showed an increasing trend from the tips of the leaf to the bases.The contents of potassium between differ-ent parts differed from each other obviously and showed a trend like lower>middle>upper.The distribu-tion of potassium content in same section of different parts tended to be:tip sections <middle sections <base sections.By the method of cluster analysis and group-average cluster analysis,roast flavor style flue-cured tobacco leaves were cut into three sections consecutively,which based on the differences of potassi-um content in different parts of tobacco leaves.
