A seasonal variation of carotenoid composition in green leaves and effect of environmental factors on it

Carotenoid compositions of green leaves are varied with the passage of season. The beta-carotene, one of the major carotenoids, is rich in summer and poor in spring, autumn and winter, while lutein, the other major, shows the opposite direction to beta-carotene. These phenomena were confirmed to be...

Summary:Carotenoid compositions of green leaves are varied with the passage of season. The beta-carotene, one of the major carotenoids, is rich in summer and poor in spring, autumn and winter, while lutein, the other major, shows the opposite direction to beta-carotene. These phenomena were confirmed to be always found in every plant, in both annual and perennial plants or in both herbaceous and woody plants. This variation was also confirmed to be seasonal and periodical on using green leaves of both evergreen and deciduous trees. The examinations for grapevine grown under different temperatures and light intensities revealed that these seasonal variations were mainly based on temperature. These results will provide important informations for both plant physiology and food nutrition
