2、揮發(fā)酸含量差異較小,且在云南的含量要略低于湖南;(2)云南4個產(chǎn)區(qū)烤煙煙葉中絕大多數(shù)揮發(fā)酸在曲靖和文山的含量明顯高于昭通和昆明,且含量差異顯著,而半揮發(fā)酸除十四酸外,其他半揮發(fā)酸及其總量均表現(xiàn)出曲靖最高,文山次之,昆明最低,且含量差異顯著;(3)湖南4個產(chǎn)區(qū)煙葉中除丁酸差異不顯著外,其他絕大多數(shù)揮發(fā)酸含量產(chǎn)區(qū)差異較大,但產(chǎn)區(qū)間差異無明顯規(guī)律;半揮發(fā)酸除十四酸外其他絕大多數(shù)半揮發(fā)酸及其總量均以慈利含量最高,邵陽最低,且產(chǎn)區(qū)間含量差異顯著。關(guān)鍵詞:烤煙;產(chǎn)區(qū);揮發(fā)性、半揮發(fā)性有機酸中圖分類號:$572文獻標志碼:A論文編號:2013
