摘　　要：[Objectives]To elucidate the impact of different drying temperatures on the biochemical profile of tobacco(Nicotiana tabacum L.)leaves,the chemical constituents and ultrastructure of Yunyan 87 leaves subjected to different curing temperature settings.[Methods]Near-infrared spectroscopy techniques were utilized to analyze tobacco leaf samples,comparing the changes in chemical constituents at different curing temperatures.[Results]The CK treatment resulted in lower concentrations of nicotine,total nitrogen,chlorine,potassium,and starch,while simultaneously enhancing the levels of total sugar,reducing sugar,and protein.In comparison to the T treatment,the CK treatment appropriately altered the cell structure,reducing the content of cell wall substances.[Conclusions]These findings suggest that low-temperature curing at 44℃during the color-fixing stage is beneficial for improving the quality of tobacco leaves.
