摘　　要：【目的】探索不同土壤类型对烤烟烟叶质体色素及其降解产物含量的影响,为选择合适的土壤类型以及有针对性地改善土壤状况提供参考。【方法】2010年在吉林延边地区选择暗棕壤、黑砂土、白浆土等3种土壤为研究对象,以当地主栽烟草品种"吉烟9号"为试材,研究不同土壤类型对烟叶质体色素及其降解产物的影响。【结果】土壤条件对烤烟烟叶质体色素及其降解产物均有不同程度的影响。暗棕壤土质条件下,烟叶的叶绿素含量(42.58μg/g)、类胡萝卜素含量(265.17μg/g)及类胡萝卜素降解产物总量(32.15μg/g)均最高,新植二烯含量(526.44μg/g)稍低于黑砂土条件下烟叶;黑砂土条件下烟叶中的新植二烯含量最高(540.78μg/g),其他质体色素和香气物质总量均处于3种土壤的中间水平;白浆土条件下质体色素含量及其降解产物均处于较低水平。【结论】暗棕壤土质更有利于烟叶香气物质的生成,且各香气成分含量较为协调。[Objective] The effects of different soil textures （dark brown soil,DBS; black sand soil, BSS;albic soil,AS） on the contents of chromoplast pigment and its degradation products of flue-cured to- bacco leaves were studied in Yanji of Jilin Province. The appropriate soil type was selected and targeted to improve the soil conditions so as to provide reference. [Method] A tobacco cultivar ＂Jiyan 9＂ was selected as the material. The effects of different soil textures on the contents of chromoplast and its degraded prod- ucts of flue-cured tobacco were researched, [Result] DBS conditions, the contents of chlorophyll （42. 58 ug/g） ,carotenoids （265.17ug/g） ,and carotenoid degradation products （32.15 ug/g） in post-cured tobacco leaf were the highest among these three conditions,and the content of neophytadiene （526.44 ug/g） was at the middle level;In BSS conditions,the content of neophytadiene （540.78 ug/g） was the highest in postcured tobacco leaf among these three conditions,and the contents of chromoplast pigment and total aroma neophytadiene were at the middle level;AS conditions,the contents of chromoplast pigment and its degradations were in lower level among these three conditions. [Conclusion] Dark brown soil is more conductive to the production of tobacco aroma, and the contents of flavor component are more coordinated.
