摘　　要：对云南省主产烟区烤烟品种K326主要化学成分进行分析,并与津巴布韦烤烟化学成分进行比较.结果表明:云南烤烟K326主要化学成分总体协调,总糖含量、还原糖含量较高,总氮含量、烟碱含量、氯含量、糖碱比、氮碱比、钾氯比均较适宜,氯含量的变异系数最大,总氮含量的变异系数最小;K326烤烟不同等级间差异显著,钾含量、氯含量和钾氯比在不同等级间差异不显著,钾含量、糖碱比、钾氯比在不同地区间差异显著,其他化学成分指标在不同地区间差异不显著;K326烤烟的总糖含量、还原糖含量、钾氯比显著高于津巴布韦烤烟,其氯含量、氮碱比显著低于津巴布韦烤烟.Main chemical components were analyzed in flue-cured tobacco leaves of cultivar K326 from Yunnan tobacco-growing areas,and were also compared with samples of flue-cured tobacco leaves from Zimbabwe.The results indicated that main chemical components of cultivar K326 from Yunnan tobacco-growing areas were harmonious in general,the contents of total sugar and reducing sugar were high,total nitrogen,nicotine,chlorine,the ratio of total sugar to nicotine,the ratio of total nitrogen to nicotine and the ratio of potassium to chlorine were medium,coefficient of variation of chlorine was the biggest,coefficient of variation of total nitrogen was the smallest.The flue-cured tobacco leaves of cultivar K326 had significant difference among different grades.The contents of potassium,chlorine and the ratio of potassium to chlorine didn＇t reach significant levels.The content of potassium,the ratio of total sugar to nicotine and the ratio of potassium to chlorine in flue-cured tobacco leaves of cultivar K326 had significant difference among different tobacco-growing areas and other main chemical indicators had no significant differences.The contents of total sugar,reducing sugar and the ratio of potassium to chlorine in flue-cured tobacco leaves of cultivar K326 from Yunnan were significantly higher than Zimbabwe flue-cured tobacco.The content of chlorine and the ratio of total nitrogen to nicotine were significantly lower than Zimbabwe flue-cured tobacco.
