湖北烤煙非揮發(fā)性有機(jī)酸含量及其與海拔高度的關(guān)系分析

Nonvolatile Organic Acid Content in Flue-cured Tobacco Leaves and Its Relationship with Altitude in Hubei

摘要: 分析了湖北烤煙非揮發(fā)性有機(jī)酸含量特征及其與海拔高度的關(guān)系。結(jié)果表明,，(1)湖北烤煙非揮發(fā)性有機(jī)酸總量平均為139.62 mg/g,，等級間表現(xiàn)為：X2F>C3F>B2F，糖酸比總體較為適宜,。(2)聚類分析將海拔高度與煙葉非揮發(fā)性有機(jī)酸含量,、糖酸比共8 項(xiàng)指標(biāo)分為3 類。B2F 和C3F 等級煙葉在海拔高度為950～1 150 m 左右,，X2F 等級煙葉在海拔高度為1 050～1 300 m 左右時(shí),，非揮發(fā)性有機(jī)酸總量相對較高,、糖酸比較為適宜。

Abstract: The characteristics of nonvolatile organic acids in Hubei flue-cured tobacco and its relationship with altitude were analyzed. The results indicated that the contents of nonvolatile organic acids averaged 139.62 mg/g, and in grades from high to low was X2F>C3F>B2F. The ratio of reducing sugar to nonvolatile organic acids was suitable in whole. Altitude and nonvolatile organic acids, the ratio of reducing sugar to nonvolatile organic acids could be classified into three groups by cluster analysis. In the leaves of B2F and C3F at the altitude of 950-1150 m, and X2F at 1050-1300 m, the contents of nonvolatile organic acids were higher and the ratio of reducing sugar to nonvolatile organic acids was favorable.
