This study was carried out to investigate the influence of the dampness of concrete floor in storeroom on the quality of packed flue-cured leaf tobacco with corrugated causes for aging. The results were summarized as follows. The moisture and relative humidity conditions at the 15cm height from the concrete floor were 2.2℃ lower and 16% RH higher than those at the 300 cm height in the storeroom. Due to loading position, no significant changes in moisture content of leaf tobacco in the third layer was found. However, in the first layer, 2.4% of increase in moisture content was found. In the case of the layer, the circumference of corrugated casses was increased more largely than in the middle. During aging, the nicotine and total sugar content and pH value in leaf tobacco were decreased. Due to loading position, the pH, nicotine and total sugar content of leaf tobacco in the first layer were decreased significantly than those in the third layer. After aging, the degree of the lightness(L) and the yellowness(b) of leaf tobacco in the first layer were dropped by 3.2 and 2.5, respectively. However, the degree of the redness(a) was Increased by 0.63. Mold was occured in the leaf tobacco at the low part of the first layer.
