우리나라 재래종중 내용성분 면에서 바람직한 향끽미 물질을 함유하고 있는 것으로 알려진 향초를 대상으로 질소시비량 및 재식밀도가 향끽미 물질에 미친 영향을 구명하여 얻어진 결과는 다음과 같다. 질소화합물의 함량은 재식밀도가 높아지면 감소하였으나 지방산 함량은 증가하였다. 혈당 3주 재배시 2, 3-methylbutanoic 산과 3-methylpentanoic 산의 함량이 가장 높았으며, solanone, furfural, furfurylalcohol, benzyl alcohol 등과 같은 중성부의 성분들은 대부분 밀식구에서 함량이 증가되었다. 질소의 증비(3∼12kg/10a)에 따라 수량은 증가하였고, 전당, 전분, 지방산 등의 함량은 감소하고, 알카로이드 함량은 2.0%에서 3.3%로 증가하였다. 2, 3-methylbutanoic 산과 3-methylpentanoic 산 함량은 질소의 증비로 감소하였으며 butanol, furfutal, furfuryl alcohol, hexanol, cinnamil, acetophenone, benzyl acetate 및 solanone 등의 함량은 감소하였다.

This study was conducted to establish the most appropriate nitrogen levels and planting densities which can attribute to increase of aromatic substances in tobacco variety, Hyangcho, maintaining its original aroma. An increase of nitrogen fertilization from 3 to 12 kg per 10a increased total alkaloid content 2.0% to 3.3%, while an increased nitrogen fertilization decreased the contents of total sugar, starch, fatty acid etc., Which seem to be the positive components relating to tobacco aroma the contents of alkaloids were decreased and total fatty acids were increased as the planting densities increased. The higher contents of 2. 3-methylbutanoic and 3-methylpentanoic acid was obtained at the density of 3 plant per pit (12,498 plant/10a). The components determined in the neutural fraction such as solanone, furfural, furfurylalcohol and benzyl alcohol were presented in higher amount at the higher densities. The volatile acids such as 2. 3-methylbutanoic acid 3-methylpentanoic acid decreased and also the contents of butanol, furfutal, furfuryl alcohol, hexanol, cinnamil, acetophenone, benzyl acetate and solanone etc., were decreased as the nitrogen level increased from 3 to 12 kg per l0a.
