Other claims from this paper (5)
- Observation Populus clones varied widely in stomatal frequency.
- Association Stomatal configurations were moderately linked with parentage.
- Observation Clones differed clearly in water balance.
- Mechanism Clones with the highest growth potential maintained crown hydration through superior water acquisition, better water transport and close stomatal control under water stress.
- Association Stomatal sensitivity to vapour pressure deficit of two rapidly growing poplar clones was associated with the known drought resistance of Populus berolinensis.
