Abstract
The conventional chemical component indexes of 444 flue-cured tobacco samples in Henan province in 2009 were analyzed,and the relationship between their sensory quality and 8 conventional chemical component indexes was studied by using grey relation analysis.The results indicated that different correlation degrees were found between 9 sensory quality indexes and the conventional chemical compositions.There were close correlations between the sensory quality and the content of total nitrogen,total sugar,reducing sugar and petroleum ether extract in the tobacco leaves.
