1、安徽農(nóng)業(yè)科學．JournalofAnhuiA．Sci．2015，43(20)：288—290，339責任編輯李菲菲責任校對況玲玲貴州煙區(qū)烤煙品種云煙87主要化學成分特征分析張麗，姬厚偉，黃錫娟，劉義萍，劉劍，何軍，段凱(貴州中煙工業(yè)有限責任公司技術(shù)中心，貴州貴陽550009)摘要[目的]分析貴州主產(chǎn)區(qū)烤煙品種云煙87主要化學成分，掌握其特點。[方法]對貴州省主產(chǎn)煙區(qū)烤煙品種云煙87主要化學成分進行分析，并與云南主產(chǎn)區(qū)云煙87化學成分進行比較。[結(jié)果]分析表明，貴州煙區(qū)烤煙品種云煙87主要化學成分總體協(xié)調(diào)，總糖含量、還原糖
2、含量較高，鉀含量略低，糖堿比略高，總植物堿含量、氯含量、總氮含量、氮堿比、鉀氯比均較適宜；鉀氯比的變異系數(shù)最大，總糖和還原糖含量的變異系數(shù)最??；云煙87烤煙總糖含量、總植物堿含量和糖堿比在不同等級樣品間差異顯著；氯含量、鉀含量和氮堿比在不同地區(qū)間差異顯著。貴州云煙87樣品總糖含量、氯含量顯著低于云南云煙87樣品，鉀氯比顯著高于云南云煙87樣品。[結(jié)論]研究可為貴州烤煙云煙87的優(yōu)質(zhì)生產(chǎn)和合理布局提供理論依據(jù)。關(guān)鍵詞貴州；云煙87；主要化學成分中圖分類號S572文獻標識碼A文章編號0517—6611(20l5)20—288
