大理烟区红花大金元烤烟化学成分变异分析

目的]对大理烟区红花大金元烤烟的主要化学成分进行变异分析。方法]从区域、年际、部位3个方面分析大理烟区红花大金元烤烟化学成分的变异情况。结果]大理红花大金元烤烟总糖、还原糖含量总体较高,钾含量较低,氯含量变异性较大;大理烟区红花大金元烤烟化学成分存在地区差异,地区化学稳定性较差;不同年份烤烟的总糖、还原糖含量较稳定,其他指标表现不稳定;不同部位的烤烟总植物碱、钾、糖碱比、氮碱比差异达到极显著水平。结论]南涧地区红花大金元烤烟化学成分整体比较协调,是大理烟区红花大金元最好的产区;中部叶的化学协调性较好。

The Variation Analysis of the Main Chemical Components of Flue-cured Tobacco of Honghuadajinyuan in Dali

Objective] The aim was to analyze the variation of main chemical components of Honghuadajinyuan flue-cured tobacco in Dali.Method] The variation of chemical components of Honghuadajinyuan flue-cured tobacco in Dali was analyzed from three aspects of region,year and parts.Result] The contents of total sugar,reducing sugar were higher,content of potassium was lower,and content of chlorine had a big variation;the chemical components varied with region,the regional chemical stability was poor;total sugar,reducing sugar contents in different year were stable,other indexes were dynamic;the differences of total plant alkali,potassium,ratio of sugar to nicotine,ratio of nitrogen to alkali in various parts were up to extremely significant level.Conclusion] Nanjian region is an ideal planting area for Honghuadajinyuan because of their overall coordinated chemical components;the chemical coordinating property of middle part leaf is good.
