| 摘 要： | 以吉烟9号为试材,于2009年采用种植密度和施钾量二因素裂区试验设计,研究种植密度和施钾量对烤烟中性致香物质含量的影响。结果表明,种植密度和施钾量及其两者互作对中性致香物质总量均有极显著影响;类胡萝卜素降解产物、棕色化产物、西柏烷类降解产物、新植二烯和其他类物质及中性致香物质总量随着种植密度的增加呈递增的趋势,随着施钾量的增加呈先降后升的趋势;随着种植密度和施钾量的增加,苯丙氨酸类降解产物则呈先升后降的趋势。综合分析认为,选择A2B3处理,即种植密度15 100株/hm2,施钾量328.5 kg/hm2组合,群体结构较为合理,烟叶香气量较高,烟叶品质较优。

| Abstract: | During 2009,a field experiment was employed to study the relationship between the contents of potassium and neutral aroma components in flue-cured tobacco leaf under plant population and K application using the tobacco cultivar Jiyan No.9 in Dunhua flue-cured tobacco producing area.Results showed that,both of the treatments,namely plant population and K application,and their interactions extremely significantly affected the contents of neutral aroma components in post-cured tobacco leaf.With the increase of... |
