Abstract

This experiment was carried out to determine the effect of nitrogen rate and maturity on the yield, quality, nitrogen compound, protein pattern, and nitrate reductase activity. The results were as follow. As the nitrogen rate increased, the degree of red color of cured leaf increased. According to the time of harvesting at their leaf position, the price of the lugs is lowest in immature stage compared with mature and over mature stage but the upper leaves were lower than mature and immature stage in price. Yield are equal in immature stage and mature stage but over mature stage is lower than mature and immture stage. There was no different protein pattern and nitrate reductase activity in nitrogen rate and mature stage.

질소비료의 증비와 숙도의 차이가 버어리종 잎담배의 수량과 품질 및 내용성분에 미치는 영향을 시험한 결과는 다음과 같다. 1. 질소비료가 증가될수록 건조엽의 적색도가 증가되었고, 2. 엽분별 수확시기를 보면 하위엽은 미숙엽에서, 상위엽은 과숙엽에서 수확할 때 kg당 가격이 가장 낮았다. 3. 미숙엽과 과숙엽은 수량이 대등하였으나 과숙엽은 수량이 떨어졌다. 4. 질소비료의 증비와 숙도에 따른 단백질 pattern의 차이는 나타나지 않았다. 5. 생육후기에는 비료수분 및 숙도에 따른 Nitrate reductase 활성도에는 차이가 나타나지 않았다.
