摘要: 以吉烟九号(当地主栽品种)为试材,于2008-2009年采用二因素裂区试验设计研究了种植密度和顶端调节剂对烤烟中性致香物质含量的影响。结果表明:种植密度和顶端调节剂及其两者互作对烤烟中的5类香气物质(类胡萝卜素类降解产物、苯丙氨酸类降解产物、类西柏烷类降解产物、棕色化反应产物以及其他类降解产物)含量均有极显著影响;其中以顶调剂的影响作用大于种植密度;随着种植密度的减小,5类香气物质含量均先降低再升高。从顶调剂对烤烟中性致香物质含量的影响来看,顶调剂B2的香气物质含量均高于B1和B3;最终得出,选择种植密度A1(16 500株/hm2),配合喷施顶调剂B2的烤烟中性致香物质含量最高,烟叶的品质较好。

Abstract: The pre-treatment of sulfuric acid methyl ester with gas chromatography-mass spectrometry(GC/MS) analysis techniques was utilized to study the difference of the organic acid content in different flue-cured tobacco leaf(L8-L12: from the bottom of the eighth leave up to the twelfth leave)and its influence on fluecured tobacco' quality.The results showed that malic acid,γ-e ketone acid,citric acid,malonic acid,linolenic acid and palmitic acid had a higher content relatively in different flue-cured tobacco leaves and they were the main acidic components,what's more,the difference between organic acids,malic acid and other organic acids content in different leaf was significantly obvious.The differencce of total organic acids content from the eighth to the twelfth leave was L8L9L12L10L11;The content proportion ranges of non-volatile acid,senior saturated fatty acid and senior unsaturated fatty acid in total organic acids were 88.49%-94.38%,3.01%-5.10% and 2.61%-6.40%,respectively.The difference analysis of organic acids content in different leaf position indicated that the organic acids content in the eighth and twelfth leaves was moderate and they could be considered as the superior and slap-up tobacco raw materials.
