Leaf N content per dry mass and per area and photosynthetic nitrogen use efficiency (PNUE) for Q. coccifera leaves from the Mediterranean (MED) and temperate (TEM) sites. Data are mean ± SE. Different letters indicate statistically significant differences (P < 0.05) between sites.
| Parameter | MED | TEM |
|---|---|---|
| N content per dry mass (%) | 1.37 ± 0.05 a | 1.21 ± 0.04 b |
| N content per area (mol m−2) | 0.18 ± 0.02 a | 0.12 ± 0.01 b |
| PNUE (µmol mol−1 s−1) | 55.3 ± 4.0 b | 103.3 ± 10.9 a |
