摘　　要：为了探讨品种间烤烟化学成分与海拔高度的相关性,在云南不同海拔(706～2356 m)植烟区采集182个烤烟中部烟叶样品,品种涉及云烟87、云烟85、K326和红大,检测了样品中的34种化学成分,通过相关分析和聚类分析,比较了化学成分及其与海拔高度相关性在品种间的差异。结果表明,4个品种中红大可溶性糖类和有机酸类含量最低,总氮、烟碱、质体色素和多酚类物质含量最高,明显区别于其他3个品种。相关分析表明,K326中总糖、总氮、烟碱、石油醚提取物等指标与海拔高度的相关性明显不同于其他3个品种,类似的结果也体现在丙二酸、丁二酸和亚油酸、β-胡萝卜素、单双糖含量等指标。因此,烟叶的化学成分及其随海拔高度的变化情况存在着较大的品种差异。In order to study the correlation between contents of chemical substances and altitude,182 of flue-cured tobacco cutter leaf samples were collected from different altitudes in Yunnan.The sampling altitude ranged from 706 m to 2356 m and the tobacco cultivars included Yunyan87,Yunyan85,K326 and Honghuadajinyuan（HD）.The main chemical substances and aroma precursors such as organic acids,polyphenols,were detected in these samples.The difference in chemical substance contents and their correlation with altitude were studied through correlation and cluster analysis.The results showed that the contents of soluble sugars,organic acid in HD were the lowest in four tobacco cultivars,while total nitrogen,nicotine,plastid pigments and polyphenols were the highest.The correlations between contents of total sugar,total nitrogen,nicotine and petroleum ether extracts and altitude in K326 were different from the other three tobacco cultivars.The same results were found in the correlation between organic acids（malonic acid,succinic acid,linoleic acid）,plastid pigments（beta renieratene）,monosaccharide and disaccharide and altitude,respectively.Therefore,the change of chemical substances in flue-cured tobacco leaves with tobacco planting area altitude is greatly affected by genotypes.
