摘 要 ：采用典型相关分析方法研究了烤烟巨豆三烯酮4种同分异构体含量与土壤理化性状之间的关系。结果表明：随着土壤pH值的提高（5.15~8.30），巨豆三烯酮2和巨豆三烯酮4含量呈现降低趋势；随着土壤有机质含量（0.54％~3.61％）的提高，巨豆三烯酮1呈现增加趋势，而巨豆三烯酮2含量呈现降低趋势；随着土壤粒径介于0.05mm和0.001mm之间的土壤颗粒百分含量（8.08%~92.93%）的提高，巨豆三烯酮2和巨豆三烯酮4含量呈现增加趋势；在一定范围内，随着土壤钙、镁、铁、铝含量的提高和钠含量的降低，巨豆三烯酮2和巨豆三烯酮4含量呈现降低趋势。

Abstract:Canonical correlation analysis was conducted on the relations between contents of 4 isomers of megastigmatrienone in flue-cured tobacco leaves and soil physical properties and nutrient conditions. 363 soil samples and its corresponding 363 flue-cured tobacco samples were collected from 12 cities in Henan Province in 2004. Soil samples were collected at 0 to 20cm depth in field. Tobacco samples were collected from 8 to 12 leaf position. Results showed that the contents of megastigmatrienone 2 and megastigmatrienone 4 fell with the increase of pH（5.15 to 8.30）, calcium, magnesium, iron, aluminium and with the decrease of sodium. The contents of megastigmatrienone 1 increased but megastigmatrienone 2 fell with the heightening of soil organic matter. The contents of megastigmatrienone 2 and megastigmatrienone 4 were improved by the boosting of the soil particles ratio between 0.05mm and 0.001mm.
