Abstract: This paper studied the effects of dagferern C/N ratio adjusted by glucose on the physiological and biocherngical characteristics and chemical components of flue-cured tobacco using wateagculture method. The results showed that all the C/N ratio treatments could increase the content of leaf chlorophyll a and chlorophyll b compared with CIA. The activity of nitrate reductase increased with the increase of C/ N ratio when C/N was under 0.5, but it was restrained when C/ N exceeded 0.5. The highest activities of leaf invertase and amylase were from the 0.5 C/ N treatment. With the increase of C/ N ratio, the N and Iag contents of flue-cured tobacco increased and then decreased, but P content increased all the way. The total sugar content of tobacco was all higher in C/N ratio treatments than that in CIA. The reduced sugar content was the highest for C/N treatment 0.5, follaved by 0.4 and 0.75, then 0.2 and 1.5.

Key words: Sugar, C/ N ratio, Flue cured tobacco, Physiological and biochanical characteristics, Chemical canponents
