Abstract: To determine regular patterns of leaf color change for Acer palmatum Atropurpureum in spring and to explore linkages between leaf color expression and leaf pigment,a spectrophotometer and leaf scanning were used to measure the chlorophyll,carotenoids and anthocyanins,as well as the hue value,brightness and purity of leaf color. Results showed that,as time passed,the chlorophyll content for the upper,mid-level and lower leaf positions increased gradually; whereas variation in the carotenoid content first increaed and then decreased. Anthocyanin in the upper and mid-level leaves increased slightly at first and then overall decreased. For the lower leaves,change in the ratio of anthocyanin to chlorophyll gradually decreased. Compared with the upper leaves,the a* value,representing the red color in lower leaves,declined rapidly with the deline of anthocyanin. Thus,leaf color turned green too early,which could affect the ornamental value of the plant.[Ch,6 fig. 1 tab. 15 ref.]
