Abstract
This study was conducted to relate among growth characteristics, quality, and chemical components for flue-cored tobacco. The results are summarized as follows : 1. Starch content in harvested green leaf was correlated negatively with leaf length, leaf width, leaf area, and leaf weight of harvested green leaf, respectively, while positively with total sugar content in cured leaf, and the ratio of leaf length to leaf width of harvested green leaf. 2. Organic matter and total nitrogen contents in the soil were correlated positively with nicotine content in cured leaf, respectively, and total nitrogen in the soil negatively with total sugar content in cured leaf. 3, Amount of fertilizer, application date of MH, priod of harvesting, and yield were correlated positively with nicotine content in cured leaf, respectively , while negatively with total sugar content. Application amount of MH was correlated positively with total sugar content, but negatively with nicotine content in cured leaf. Also amount of compost was correlated negatively with nicotine content in cured leaf. 4. The ratio of total sugar to nicotine (TS/N) per plant was correlated positively with price (Won/kg) and specific leaf area, but negatively with leaf length. leaf width, leaf area, harvested leaves, and leaf weight in cured leaves, respectively. Yield was correlated negatively with TS/N per plant. 5. TS/N of the best quality tobacco per plant was 12.0. Those of the best quality tobacco in each stalk position were 42.1 for first~third leaf, 28.4 for 4th~6th leaf , 23.7 for 7th~9th leaf, 7.7 for l0th~12th leaf , and 7.8 for over 13th leaf from bottom, respectively. 6, When TS/N was 12.0, optimum values of growth characteristics per plant were 100.5
