Fig. 7

Relationships between growth traits and Pnmax as well as PNUE. Height (11a), tree height at age 11; DBH, diameter at breast height; Pnmax, area-based maximum net photosynthesis; PNUE, photosynthetic nitrogen use efficiency. Points represent trait values for each individual of each species. Explained variance (R2) and P values are shown. Solid lines in each panel represents significant linear regression
