Abstract
Field experiment in Yanbian area was carried out to study the effect of nitrogen fertilizer rates on contents of aroma components and flavor quality of a tobacco(Nicotiana tabacum) cultivar Jiyan 9 from 2005 to 2006.The main results showed that aroma constituents were not harmonious and flavor quality was poor in the treatment of nitrogen fertilizer rates less than 60 kg per hectare or more than 60 kg per hectare,while treatment of 60 kg nitrogen fertilizer per hectare could increase the flavor components contents of cembranenoids,carotenoids and browning reaction products.Therefore,the comprehensive quality was obviously improved with small odor,moderate irritation,comfortable lingering,mild smoke and good combustibility.It was suggested that 60 kg·hm-2 nitrogen fertilizer was optimal for the tobacco plant growing and could increase the flavor quality of tobacco leaves.
