담배(Nicotiana tabacum L.)의 生長과 Alkaloid 生成에 미치는 無機營養素의 影響에 관한 硏究 = A Study on the Influence of Mineral Nutrients on the Growth and Alkaloid Formation of Tabacco Plant (Nicotiana tabacum L.)

다국어 초록 (Multilingual Abstract)

This study was conducted to invest irate the influence of mineral nutrients on the growth, Alkaloid formation and quality of tobacco plants. Tobacco plants were grown at different concentration of nine mineral elements : nitrogen, Phosphorus, potassium, magnesium, iron, manganese, molybdenum, boron, and zinc;
by hydroponics. The growing character isle, chemical components in the leaves and nicotine format ion were investigated and analysed. The results obtained are as follows,
1.In the plot of high level of nitrogen, growth of the aerial part was large, nitrogen and nicotine contents in the leaves and roots were high and protein contents in the leaves was high.
2.In the plot of high level of potassium the amount of root growth was large, the contents of sugar in the leaves was high, and the quality of the leaves was improved.
3.Under the condition of low iron level, high levels of phosphorus increased total nitrogen and nicotine contents in the roots.
4.The lower concentration of nitrogen, potassium and iron in ctrl tare solution were, the higher the T/R ratio was.
5.Dry weight and the nicotine formation amount of the roots were increased in the plot of high level of iron.
6.High level of nitrogen and manganese induced less Carbohydrate/Alkalo fraction and deteriorated the quality of cured leaves.
