In this paper, the leaf traits (including the leaf dry weight, leaf area, and specific leaf weight), chlorophyll relative content and chlorophyll fluorescence parameters of the six superior Carallia brachiata clones were determined and analyzed. And the one-way ANOVA and cluster analysis was carried out. The results showed that there were no significant differences in leaf dry weight and leaf area between leaves of different clones, and the relative contents of chlorophyll were the significant difference. Different clones had different ability of light energy absorption and utilization. Some parameters (Fo, Fv/Fm, Fv/Fo, ФPSⅡ, ETR) of chlorophyll fluorescence among different clones were significantly different. The NO. C-15 clone had a higher level of the photochemical efficiency value (ΦPSⅡ) than the other clones, while the non-chemical quenching coefficient (qN) was relatively low, and had a high electron transport rate(ETR). The correlation analysis showed that the chlorophyll content of the clones with better leaf growth was higher, and that of the clones had the higher PSⅡ photosynthetic efficiency. The NO. C-15 clone had higher relative chlorophyll content and stronger photochemical properties, which could be vigorously promoted to the future research and development.
