Canonical correlation between physical properties in flue-cured tobacco leaves and soil property in Henan

353 soil samples from 0 ~ 20 cm depths and their corresponding flue-cured tobacco samples from 8 to 12 leaf position were collected from 12 regions in Henan Province in 2008,and the canonical correlation analyses were conducted on the relations between physical properties in flue-cured tobacco leaves and soil property. The results that within a certain range,tobacco stem content with soil pH,total potassium content and Mg content were significantly negatively correlated,with Na content was significantly positively correlated; Balance moisture content of tobacco leaves with soil available potassium,total phosphorus and Mg content was significantly positively correlated; Tobacco leaf weight with soil available potassium and total phosphorus content was significantly negatively correlated; Tobacco resistance to tension and tensile strength was significantly negative correlation with soil Fe content.
