Other claims from this paper (8)
- Association The intermediate group of Quercus robur trees was more severely infested with Asterolecanium quercicola.
- Association Net photosynthesis of Quercus robur showed a significant correlation with photon flux density in all three groups.
- Association Net photosynthesis correlated more positively with pre-dawn leaf water potential in moderately and severely water-stressed Quercus robur trees.
- Association Stomatal conductance of Quercus robur showed little correlation with ψpd values.
- Association Stomatal conductance of Quercus robur in groups b and c showed a significantly higher sensitivity to relative ambient humidity.
- Association A close coupling exists between net photosynthesis, ψpd, RH, FTm and S in Quercus robur.
- Association Polyphenolic concentrations were significantly higher in group b than in group c Quercus robur trees.
- Mechanism The higher infestation of group b trees may be explained by host specificity and changes in nitrogen levels.
