Abstract: To investigate the content of plastid pigments in tobacco leaves at different maturity，the tobacco cultivars ‘K326’、‘ Jiucaiping2’、‘Honghuadajinyuan’、‘ Guiyan2’、‘ Nangjiang3’、‘ Bina1’were used as experimental material and the comparative study of the content and forms of plastid pigments in tobacco leaves at different mature stage was carried. The results indicated that there was significant difference in chromoplast pigment of different genotypes during maturity of tobacco leaves and the content of chromoplast pigment of different genotypes decreased during maturity of tobacco leaves but different degradation rates of chromoplast pigment of different genotypes. Then different flavor quality and style of different genotypes was showed because of the content of degradation products. And there was extremely significant correlation among the chromoplast pigment of different genotypes during maturity of tobacco leaves. The rapid detection technology of maturity may be expressed by one of chromoplast pigment. These results are important to improve the selection and evaluation of tobacco varieties of tobacco fragrance quality and fragrance quantity, and provide the basis for rapid detection of tobacco leaves maturity and classification of tobacco leaves.
