Abstract:

In order to make clear the leading factors that affected smoking quality of tobacco leaf in Guizhou Procince, we collected 388 tobacco leaf samples in 2007-2009, evaluated their main chemical components, sensory quality, physical property and smoking quality. The results showed the smoking quality went down when the leaf was light in color; the smoking quality and total sugar, reducing sugar content decreased as the nicotine, total nitrogen and protein content increased. The factores leading smoking quality were leaf color, leaf weight, leaf density, nicotine content, sugar content, total nitrogen content, potassium content, protein content, the rate of sugar to nicotine and K/Cl.
