| 摘 要： | 以湖北省清江流域7个烤烟主产区21个烟叶样品为供试材料,对烤烟中10种主要化学成分进行了相关分析和因子分析,并利用因子得分进行综合评价。结果表明,烤烟主要化学成分存在显著或极显著的相关性。相关系数矩阵前4个特征根的累计贡献率已达91.400％。由化学成分的因子载荷矩阵得到4个主因子,即碳氮因子、燃烧性因子、氮碱比因子和淀粉因子。综合评价为利用烤烟化学指标评价烤烟品质提供新方法,并为烟叶的工业可用性提供参考。

| Abstract: | By the method of correlation analysis and factor analysis,total 27 tobacco samples from 9 tobacco-growing counties scattered in the administrative regions of Hubei Province were analyzed with data from 10 main chemical components in flue-cured tobacco leaves.A comprehensive evaluation was carried out by using the factor scores.The results indicated that the main chemical components in flue-cured tobacco leaves were highly positive-correlated with that of the others.The contribution rate of first-four charac... |
