摘要
采集云南烟区红花大金元（红大）、K326、云烟85、云烟87等4个主栽品种初烤烟B2F、C3F和X2F的烟叶样品6995份,采用连续流动法检测烟叶糖含量,分析了糖含量的变化特点.结果表明：云南烤烟糖含量较高,上、中、下3个部位烟叶的总糖含量均值分别约为29%、33%、31%,还原糖含量分别约为25%、28%、27%,上部烟叶两糖差约为3.8%,中部和下部烟叶两糖差约4.5%.云南烤烟总糖含量的主要分布区间：上部叶24%～36%,中部叶28%～40%,下部叶26%～38%;还原糖含量的主要分布区间：上部叶20%～30%,中部叶24%～34%,下部叶22%～32%.不同种植区烟叶的糖含量存在差异,滇西种植区烟叶糖含量较高,滇中、滇东、滇西南种植区居中,滇东北、滇东南种植区较低.云南烤烟糖含量在种植年份和品种间存在差异,红大和K326糖含量略低于云烟85和云烟87,红大烟叶的两糖差最小.
The sugar contents of 6 995 flue-cured tobacco samples including B2F,C3F and X2F leaves of Hongda,K326,Yunyan85 and Yunyan87 from Yunnan Province were analyzed with continuous flow analyzer.The results showed that Yunnan tobacco leaves were characterized by rich sugar.Total sugar contents range of upper,middle and lower leaves were 24%～36%,28%～40% and 26%～38% with means of 29%,33% and 31% respectively,and reducing sugar contents ranges were 20%～30%,24%～34% and 22%～32% with means of 25%,28% and 27% respectively,and TS-RS were 3.8%,4.5% and 4.5% respectively.There were significant difference of sugar contents among planting areas,annual means and varieties.The sugar contents of leaves from west was higher,followed by centre,east and southwest,and northeast and southeast of Yunnan were lower.The sugar contents of Hongda and K326 were higher than that of Yunyan85 and Yunyan87.TS-RS of Hongda is the lowest.
