STUDIES ON RELATION BETWEEN LEAF AND SMOKE CONSTITUENTS OF FCV TOBACCO

Abstract

Significant positive correlations were observed between smoke total particulate matter (TPM) and leaf nicotine, solanesol & petroleum ether extractives (PEE); smoke solanesol and leaf nicotine & solanesol. A positive correlation was obtained between smoke solanesol and leaf PEE. Linear regression equations were developed between TPM, tar & nicotine and different leaf constituents to predict the smoke constituents. In the case of Karnataka Light Soils (KLS) and Northern Light Soils (NLS) samples, the frequencies of chi-square (X2) values for TPM and tar were in the range of 0.00 -0.99 were 73.3 & 85.0% and 79.1 & 88.4%, respectively. For nicotine in KLS and NLS samples, X2 values in the range of 0.00 - 0.49 were 100.0 and 92.86%, respectively. Thus, the selected regression equations can be employed for predicting TPM, tar and nicotine in smoke using the values of leaf nicotine, reducing sugars, chlorides, potassium, PEE and solanesol.
