Research on influencing factors of flue-cured tobacco starch content and its relationship with tobacco leaf quality

Starch,as an important influence factor of tobacco quality,has been a hot research topic of tobacco. Aiming at the present research on flue-cured tobacco starch at home and abroad and the domestic issue of higher starch content,the paper summarized the influence factors of starch content in flue-cured tobacco leaves from the aspects of environmental factors and agronomic measures,and illuminated the correlation between starch content of flue-cured tobacco and appearance quality,physical properties,chemical composition and sensory quality evaluatio,also analyzed the present measures to reduce flue-cured tobacco starch content,and discussed the starch content reducing system formed by combining relative techniques. Finally,the paper previewed the research on molecular breeding of flue-cured tobacco with low starch content and starch physiology.
