摘　　要：在河南豫中烟区研究了4种典型质地土壤烤烟主栽品种NC89不同生育时期和调制后烟叶质体色素含量变化的差异。结果表明,砂土烟叶β-胡萝卜素和总类胡萝卜素在烤后烟叶样品中含量较高,其余几种色素降解程度均较大;砂壤土烟叶中大部分色素含量在烟株现蕾期至尚熟时下降较为缓慢,成熟采收时下降较为明显,在烤后烟叶中叶绿素、β-胡萝卜素和总类胡萝卜素残留较少,质体色素降解充分;壤土烟叶各种色素含量随生育期推进下降趋势均较明显,烤后烟叶样品中质体色素含量也较低,残留较少;黏土烟叶中各种色素含量在现蕾期至尚熟时含量开始下降,但在成熟采收时含量较高,色素降解程度低,烤后烟叶中叶绿素和类胡萝卜素含量偏高。砂壤土和壤土植烟有利于烤烟香气前体物质的积累和适时转化。Four kinds of soils with different textures in middle region of Henan Province tobacco area were selected to investigate the differences of Chromoplas pigment contents at different growth stages and flue-cured tobacco leaves.The results showed that for sandy soil the contents of β-carotene and total carotenoids were higher in flue-cured tobacco leaves but other pigments degraded more;for sandy loam soil most pigments decreased slightly before the mature stage but then decreased evidently,chlorophyll,β-carotene and total carotenoids remained less in the flue-cured tobacco leaves,and the chromoplast pigment degraded completely;for loam soil,all pigments decreased clearly with the growth stage and remained less in flue-cured tobacco leaves;for clay soil,all pigments decreased slightly before the mature stage but degraded less and were higher at the mature stage,in flue-cured tobacco leaves chlorophyll and total carotenoids were on the high side.Flue-cured tobacco cultivation in sandy loam and loam soils were in favor of the accumulation and timely transformation of fragrant precursors.
