香料烟叶片主要外观性状与化学成分关系的研究

Relationship between Main Appearance Characteristics and Chemical Constituents in Oriental Tobacco

利用Samsun品种，研究了香料烟叶片颜色、光泽、叶面积和叶质量等4个外观性状与化学成分的关系。结果表明：颜色和叶面积与化学成分的关系较为密切，控制颜色深化和减小叶面积能明显提高糖含量，并可降低总氮和蛋白质含量，利于改善烟叶质量；叶面积减小也会使烟碱含量降低。

The relaionship between main appearance characteristics of leaf such as curing color, brilliance,leaf area, weigt per unit leaf area etc. and chemical constituents in oriental tobacco cultivar Samsun were studied.The results shawed tha the curing color and leaf bo had a cha relationship with chedcal conshtuents. Withcontrolling the curing color and decrnaing the leaf area, the content of sugar obviously inceased together with decreased the content of total nitrogen and protein. But the content of nicotine also decreased by decreasing the leaf area.
