To investigate the changes of physicochemical properties of leaf tobacco during storage, cured leaves (both flue-cured(KF109) and burley(Burley 21) : 4 grades of leaves) were stored under the natural warehouse condition(room temperature) and processed leaves(both Rue-cured(NC82) and burly(Burley 21) : 6 grades of leaves) were stored at storerooms in tobacco processing plants(flue-cured Cheongju plant ; 2nd, 4th and 5th floor, burley : Kwangju plant ; 2nd floor, Chonju plant : 3rd and 5th floor). Tobacco leaves were sampled and analyzed every 3 months. Total sugar content of flue-cured leaf decreased slightly and the redness degree of leaf increased after 15 months' storage under the natural warehouse conditions. The pH of cured leaves were lowered both flue-cured and burley, and the decreasing rate of pH was large in flue-cured(0.24) as compared with burley(0.14). There was no significant differences of physicochemical properties of processed leaf among storerooms during 15 months' storage. The decreasing rate of processed leaf pH was somewhat large in flue-cured(0.26) as compared with burly (0.20), and in thick leaves as compared with thin leaves. The redness degree of flue-cured leaf increased slightly, while the degree of lightness and yellowness lowered slightly during storage. The lightness degree of burley leaf lowered slightly, too. The ageing process of cured leaf was similar to that of processed leaf, it is considered that the passing days after curing will be more reasonable than the passing days after processing for the establishment of proper ageing period.

This study was carried out to investigate the effects of suckers on chemical components with vertical and horizontal hanging method during stalk-cut curing in burley tobacco. The elongation and dry weights of suckers were increased until 14 days in vertical hanging method, and until 7days in horizontal hanging method after the beginning of curing. The contents of nicotine, protein-N and $NH_4$-N were decreased at treatment of more suckers during the curing. However, there was no significant difference by the hanging method. Solanone, damascenone, megastigmatrienone and 4-methyl phenol were increased gradually during curing. Those were increased with treatment of fewer suckers compared to treatment of more suckers. There was no significant difference by the hanging method.
