摘要: 通過初烤煙葉外觀質(zhì)量量化評(píng)分建立與主要化學(xué)成分的關(guān)系,。結(jié)果表明，成熟度與兩糖比和糖堿比分別呈極顯著（P<0.01）和顯著（P<0.05）正相關(guān),。油份與氮堿比呈極顯著負(fù)相關(guān)（P<0.01）,，與還原糖和煙堿的含量呈極顯著正相關(guān)（P<0.01）。身份與氮堿比和兩糖比分別呈極顯著（P<0.01）和顯著（P<0.05）負(fù)相關(guān),，與還原糖和總氮呈極顯著（P<0.01）正相關(guān),。葉片結(jié)構(gòu)與煙堿、淀粉,、蛋白質(zhì)呈極顯著（P<0.01）負(fù)相關(guān)和糖堿比呈顯著（P<0.05）負(fù)相關(guān),，與還原糖和兩糖比分別呈極顯著（P<0.01）和顯著（P<0.05）正相關(guān)。色度與氮堿比呈極顯著（P<0.01）負(fù)相關(guān),，與總糖呈極顯著（P<0.01）正相關(guān),。初步建立了初烤煙葉外觀質(zhì)量與主要化學(xué)成分回歸方程。Abstract: The correlation analysis between the outlook quality and main chemical component of flue-cured tobacco leaves was studied through 302 samples of bijie district. The results indicated that the extreme significant (P<0.01) and significant (P<0.05) positive correlation of the maturity with the ratio of total sugar and reducing sugar and that of reducing sugar and nicotine, respectively. The oil content had extreme significant (P<0.01) negative effect on the ratio of total nitrogent and nicotine, extreme significant (P<0.01) positive effect on reducing sugar and nicotine. It had that extreme significant (P<0.01) and significant (P<0.05) negative correlation of leaf degree with the ratio of total nitrogent and nicotine and that of reducing sugar and nicotine respectively, extreme significant (P<0.01) positive correlation of leaf degree with reducing sugar and total nitrogent. There existed extreme significant (P<0.01) negative correlation between chroma and the ratio of total nitrogent and nicotine, and extreme significant (P<0.01) positive correlation between chroma and total sugar. Preliminarily, the regression equation was established between the outlook quality and main chemical components of flue-cured tobacco leaves.
