Abstract: Effects of different light and temperature cultivation on fragrant precursor and fragrant substance of the flue-cured tobacco leaves were conducted through C3F flue-cured tobacco leaves in Liuyang tobacco area , whose seedling stage was dealted with different levels of light and temperature, for a comparative analysis of carotenoid, chlorogenic acid, rutin, nonvolatile organic acid, neutral aroma components. Results showed that the content of carotenoid, chlorogenic acid and rutin are the highest in light environment curing barn, but the lowest in total amount and highest in citric acid, with the content of chlorogenic acid and rutin of control treatment higher than improving temperature and nonfill-in light treatment. Nonvolatile organic acid and malic acid are the highest in improved tempetature and filled-in light curing barn. Huge differences were found among every treatment in chlorophyll and carotenoid degradation products. The highest content was neophytadiene in light environment barn and carotenoid degradation products in improving temperature and fill-in light treatment. Improving temperature and fill-in light is the most advantageous to aroma quality in fragrant substance.
