Abstract: The concentrations of anthocyanins and chlorophyll b in the different mature leaves of‘Tsukuba 3’and David peach have been investigated. The results showed that, with the elevation of leaf2position , in the‘Tsukuba 3’peach leaves , anthocyanins and chlorophyll b contents increased. While in David peach leaves, there was very low content of anthocyanins without variation, and the content of Chlorophyll b varied very little. The results of correlation analysis showed that Chlorophyll b content had a remarkable positive correlations with anthocyanins content ( P < 0. 001 ) . The UV and were identified. The results svisible light absorbing capabilities of‘Tsukuba 3’and David peach leaves howed that, the UV-light absorbability of‘Tsukuba 3’peach leaves was similar to that of David peach leaves, but its green2light absorbability was much stronger than that of David peach.

Key words: Anthocyanins, Chlorophyll b, Peach trees, Green light, UV2light
