Table II
Probability values (P) of the ANCOVA analyses to test for differences in the Y-intercept and slope of the equations of the three leaf stages in each species (n = 30 per leaf stage in each species). A significant interaction indicates differences in slope; only if the interaction is not significant can differences in the Y-intercept (leaf stage factor) be interpreted.
| Leaf stage | CCI | Interaction | |

| Q. pyrenaica | < 0.0001 | < 0.0001 | < 0.0001 |
| Q. faginea | < 0.0001 | < 0.0001 | 0.0106 |
| Q. suber | < 0.0001 | < 0.0001 | < 0.0001 |
| Q. ilex | < 0.0001 | < 0.0001 | 0.0009 |
