1、云南省不同品种和产区烤烟中氯含量的差异分析吴玉萍，师君丽，赵立红，夏振远：文大荣，陈萍，邓建华（云南省烟草农业科学研究院，云南玉溪653100）摘要：为了解云南烟叶氯含量的特征，对2004-2008年全省12个烤烟种植区不同主栽品种的10190个烤烟烟叶样品氯含量进行了统计分析。结果表明，云南省烤烟烟叶样品的氯含量绝大部分在1.0-6.0g/lg之间，各部位氯含量在1.0-6.0g/kg之间的均占70%以上；各部位氯含量小于3.0g/kg的均占60%以上。烟叶样品氯含•量在州（市）间和詁种间均存在一•定的差异。氯含量总体上大理州和红河州相对较高，普
2、洱市和文山州相对较低。云南4个主栽品种烟叶氯含量红花大金元品种显著高于其他3个晶种，K326是屮、上部叶显著高于云烟85、云烟87,下部叶K326、云烟85和云烟87差异不显著。云烟85和云烟87中部烟叶差异不显著，上部叶差异达显著水平。关键词：氯；烤烟；云南；品种中图分类号：S572.062文章编号：1007-5119（2011）04-0071-04DOI:10.3969/j.issn.1007-5119.2011.04.016ChlorideContentVariationinFlue-curedTobaccoamongVariousVarie
