ABSTRACT	We compared the influence of light intensity and illumination time on the chlorophyll (Chl) and carotenoid content, and on the Chl a/b and carotenoid/Chl ratios of leaves from the same shoot of normal and of Golden-leaves fig (Ficus microcarpa cv. Golden-leaves). Golden-leaves fig possesses light-sensitive leaves with various amounts of Chl and carotenoids and various ratios of Chl a/b and carotenoids/Chl under the same illumination. It appears that the deficiency of Chl is not directly associated with the loss of carotenoid, but the alteration of Chl a/b ratios might be related to that of the carotenoids/Chl ratio. It is likely that the relationship between synthesis of Chl b and carotenoids is more intimate than that of Chl a and carotenoids. The unique characteristics of Golden-leaves fig makes this plant a useful tool for studying the photobiochemistry and photomorphogensis of higher-plant chloroplasts.
