1、云南省不同品種和產(chǎn)區(qū)烤煙中氯含量的差異分析吳玉萍，師君麗，趙立紅，夏振遠(yuǎn)：文大榮，陳萍，鄧建華（云南省煙草農(nóng)業(yè)科學(xué)研究院，云南玉溪653100）摘要：為了解云南煙葉氯含量的特征，對(duì)2004-2008年全省12個(gè)烤煙種植區(qū)不同主栽品種的10190個(gè)烤煙煙葉樣品氯含量進(jìn)行了統(tǒng)計(jì)分析。結(jié)果表明，云南省烤煙煙葉樣品的氯含量絕大部分在1.0-6.0g/lg之間，各部位氯含量在1.0-6.0g/kg之間的均占70%以上；各部位氯含量小于3.0g/kg的均占60%以上。煙葉樣品氯含?量在州（市）間和詁種間均存在一?定的差異。氯含量總體上大理州和紅河州相對(duì)較高，普
2、洱市和文山州相對(duì)較低。云南4個(gè)主栽品種煙葉氯含量紅花大金元品種顯著高于其他3個(gè)晶種，K326是屮、上部葉顯著高于云煙85、云煙87,下部葉K326、云煙85和云煙87差異不顯著。云煙85和云煙87中部煙葉差異不顯著，上部葉差異達(dá)顯著水平。關(guān)鍵詞：氯；烤煙；云南；品種中圖分類號(hào)：S572.062文章編號(hào)：1007-5119（2011）04-0071-04DOI:10.3969/j.issn.1007-5119.2011.04.016ChlorideContentVariationinFlue-curedTobaccoamongVariousVarie
