摘　　要：采用改进后的Arnon法及气相色谱一质谱联用技术，探索不同自肋烟品种叶绿体色素及相关致香物质的变化规律。结果表明，成熟时品种间叶绿素含量0．623—0．735mg／g，变异系数7．07％；类胡萝h素含量0．169—0．217mg／g，变异系数11．82％；叶绿素／类胡萝卜素比值2．887—4．336，变异系数18．0r7％；不同品种间叶绿素／类胡萝h素比值差异〉类胡萝卜素〉叶绿素。调制后品种间叶绿素裂解的产物含量148．12—230．01n，g／g，变异系数17．39％；类胡萝卜素类降解产物含量53．036—91．344mg／g，变异系数23．33％；品种间类胡萝卜素类降解产物含量差异〉叶绿素裂解的产物；综合结果，TN90、Kyg07品种成熟时叶绿素含量略低，但类胡萝卜素含量略高，叶绿素／类胡萝卜素低，比叶重较适宜，晾制后相应降解的致香物多，更有利烟叶香气品质的形成。：The improved Arnon method and gas chromatography-mass spectrometry were used to explore hurley tobacco chloroplast pinents and related changes of aroma of different varieties. The results showed that mature varieties total chlorophyll was 0.623 -0.735 mg/g, coef- ficient of variation was 7.07 % ; carotenoid content was 0. 169 - 0.217mg/g, coefficient of variation was 11.82 %, chlorophylL/carotenoid ratio was 2. 887 -4.336, and coefficient of variation was 18.07 %. Total chlorophyll/carotenoid ratio, carotenoids, total chlorophyll of dif- ferent varieties, and modulated chlorophyll pyrolysis product varieties content was 148.12 -230.0ling/g, coefficient of variation was 17.39 % ; degradation products of carotene content was 53.036 -91. 344 mg/g, coefficient of variation was 23.33 %. Degradation products be- tween the carotenoids content; chlorophyll pyrolysis product of the variety; consolidated results, TN90, Ky907 varieties mature chlorophyll content is slightly lower, but slightly higher carotenoid content, total chlorophylL/carotenoid low, specific leaf weight is more appropriate, air system for the corresponding degradation of property and more aroma, more conducive to the formation of quality tobacco flavor.
