Abstract:In order to understand the leaf functional traits in different strains of Prunus campanulata, the leaf index, specific leaf area, chlorophyll content and leaf dry matter content in four strains were studied. The results showed that there were significant differences in leaf characteristics among the four strains. Leaf index had negative correlation with leaf dry matter content (P<0.05). Specific leaf area had significant positive correlation with chlorophyll content (P<0.01) while had significant negative correlation with leaf dry matter content (P<0.01). By comprehensive evaluation, the strain of CB3 has high chlorophyll and leaf dry matter contents, long flowering and dense flowers, so that it's recommended as an ornamental and street tree species.
