버어리종 담배의 염소에 관한 연구 : 염소시용시기 및 시용량이 담배의 염소흡수 및 엽중분포에 미치는 영향 The effects of application time and rate of chlorine on the chlorine absorption and distribution in each stalk position of the plants = Studies on the Chlorine of Burley Tobacco Plants

다국어 초록 (Multilingual Abstract)

Effects of application time and rate of chlorine on the chlorine absorption and distribution at different stalk positions of the plants were investigated in burley tobacco grown under the pot condition. Treatment consisted of 6 application times(from 2 weeks before transplanting to 8 weeks after transplanting with 2 weeks' interval) and 2 application rates(2g and 4g-KCl/pot) by 6×2 factorial experimental design.
The tobacco plants took up the chlorine rapidly just after chlorine application, and the chlorine content of leaf was increased proportionally to the rate of chlorine application. The chlorine was accumulated much in lower leaves when chlorine was applied early, while the chlorine accumulated much in upper leaves when chlorine was applied late.
The chlorine content of leaf was negatively correlated to the degree of brightness, red color and yellow color of cured leaf.
Significant increases in cured leaf ratio, leaf thickness, leaf weight and weight per unit leaf area of harvested leaf were obtained with increased chlorine application. When the chlorine was applied early, the leaf weight showed increasing tendency.
