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.
