Abstract: Climatic factors are most important to determine the quality of flue-cure tobacco and control the aroma style by affecting the content and composition of aroma components.In this paper, in order to provide theoretical bases for further study on the relationship between ecological conditions and flue-cure tobacco quality, researches on effects of climatic factors on aroma components of flue-cured tobacco, including the following six aspects: plastid pigment, cembranoids, maillard reaction products, phenolic compounds, alkaloids, lipids compounds and their degrading products, were reviewed.
