Abstract: The physical characteristics of 380 samples（C3F,B2F 190,respectively） in nine counties of Henan tobacco leaf（four main producing areas of Xuchang city,Luohe city,Shangqiu city and Pingdingshan city） were measured. Statistical analysis was conducted to determine the differences and similarities in the physical properties of tobacco leaves in the main producing areas of Henan. The results showed that the physical characteristics of tobacco leaves in different tobacco areas were different,and the leaf thickness and leaf density of the main producing areas in Henan were higher than those in the main areas. The filling value of Xuchang and Luohe was suitable,Pingdingshan and Shangqiu tobacco filling value is higher,Xuchang,Luohe,Shangqiu tobacco between the three tobacco areas are relatively close.

Key words: tobacco leaf, physical characteristics, difference, Henan province
