摘　　要：采用典型相关分析方法研究了湖南烤烟叶片硝酸盐和亚硝酸盐含量与若干品质指标间的关系.结果表明:不同等级烟叶硝酸盐、亚硝酸盐含量与烟碱、总氮的第一典型相关系数均达到1%极显著水平,其所包含的相关信息占两组变量间总相关信息的75 41%～86 92%,且这一相关关系主要由硝酸盐与烟碱、总氮间的相关所引起;不同等级烟叶硝酸盐、亚硝酸盐含量与石油醚提物、总糖、还原糖的第一典型相关系数也均达到1%极显著水平,其所包含的相关信息占两组变量间总相关信息的77 16%～92 04%,且这一相关关系主要由硝酸盐与还原糖、总糖间的相关所引起.不同等级烟叶硝酸盐、亚硝酸盐含量与烟叶11种营养元素间的典型相关系数则均未达到5%的显著水平.By using the method of canonical correlation, the relationship was analyzed between nitrate and nitrite content and some quality traits of flue-cured tobacco leaf in Hu′nan tobacco-growing areas. The results indicated that the first canonical correlation coefficient of content of nitrate and nitrite was significant at 1% level with content of nicotine and total N. The correlation information of the first canonical correlation coefficient accounted for 75.41%～86.92% of the total, and was mainly caused by the correlation between nitrate content and nicotine and total N. Similarly, the first canonical correlation coefficient of content of nitrate and nitrite was significant at 1% level with content of reducing sugar, total sugar and petroleum ether extract. The infor-mation of the first canonical correlation coefficient accounted for 77.16%～92.04% of the total, and was mainly caused by the correlation between content of nitrate and reducing sugar and total sugar. The canonical correlation coefficient of content of nitrate and nitrite was not significant at 5% level with content of 11 kinds of nutrition elements in flue-cured tobacco leaf.
