Chemical Studies on Tobacco Smoke: XXI: Correlation and Multiple Regression among Selected Cigarette-Smoke Constituents and Leaf Characteristics of Bright Tobacco

Simple correlation and multiple regressions among 160 variables of leaf characteristics and smoke constituents were calculated, based on experimental cigarettes made from 4 cultivars of bright-type tobacco, each from 8 stalk positions. Smoke composition is a function of the botanical, physical, and chemical properties of leaf tobacco used to make the cigarette. Detailed simple correlation data, multiple-regression equations, and expressions of variety and stalk position as factors of TPM and BaP formation are presented
