植物间存在着化感作用,适当的种植群落结构可以改善作物的品质。本研究根据烟草与不同原料植物间作后致物质的变化情况,探索一种丰富烟叶气,提高烟叶质量的新途径。烟草与原料植物(薰衣草,迷迭,叶天竺葵,猫薄荷和玫瑰花)间作后,用固相微萃取(SPME)及气相色谱-质谱联用(GC/MS)分析对其叶片中致物质的变化,在烤烟与原料植物间栽的小环境动态生态系统中,烟草和原料植物的致成分都有变化。与对照烟叶相比,烤烟致物质的变化呈现了3种不同情况:原料植物特有的致成分转移至处理烟叶;原料植物、对照、处理烟叶共有致物质含量出现变化;间栽后烤烟出现新的致成分。进一步研究烟草和原料植物间相互作用情况,寻找到植物间化感作用影响烟叶致成分变化的规律,可为丰富烟叶致成分,构建良性烟田生态系统,建立以烟为主、原料为辅的耕作制度提供理论支撑,对探索生产绿色、安全的烤烟具重要意义。
Agronomic measures mainly affected physiological and biochemical metabolism of tobacco growth and development, and fatherly affected the content and proportion of aromatic matters. In order to explore the intercropping application in the tobacco field, we contrasted the effect of monoculture of tobacco with inter-cropping effect of K326 and four aromatic plants of Lavandula pedunculata, Rosmarinus officinalis, Pelargonium roseum, Nepeta cataria, Rosa rugosa respectively. Gas Chromatography-Mass Spectra/Olfactory (GC-MS/O) was applied in this dissertation. GC-MS/O is a powerful way in screening aroma compounds in tobacco leaves effectively, which was combined GC-MS to Olfactory. The result showed that the change of flue-cured tobacco aroma substances presented three different situations in the small dynamic ecosystem environment that tobacco intercropped with different fragrant plants: some specific aroma components of fragrant plants transferred to experimental group; the pro
