摘　　要：为了解红花大金元品种外观质量与感官质量的相关性,采集凉山烟区红花大金元外观质量和感官质量数据,采用典型相关分析法对两者的相关性进行研究。结果表明:有两组典型相关变量达到显著水平,相关系数为0.8515与0.8281;感官质量指标刺激性和余味与外观质量指标身份存在较高的负相关性;而香气量与烟叶成熟度、油分、色度相关性较高且在一定范围内随着三者的提高而不断增加。The sampling data of appearance and sensory quality of Honghuadajinyuan in Liangshan tobacco area were collected,and their correlations were researched using the method of canonical correlation analysis. The results showed that there were two sets of canonical correlation variables reached the significant level with the correlation coefficients of 0. 8515 and 0. 8281. There were obvious negative correlations of sensory quality irritancy and after taste with appearance quality identity; the volume of aroma had close relationships with tobacco maturity,oil and chrominance,and improved with their increase within a certain range.
