e0“hydraulic allometry adjustments of whole plant and leaf physiological response were well coordinated, buffering the water stress experienced by GUA8 plants. In turn, this explained their higher relative growth rates compared to the rest of the genotypes under water-stress conditions.”

Other claims from this paper (8)
- Association Wild olive genotype growth responses to water stress differed and were best explained by net CO2 assimilation rate changes.
- Mechanism Net photosynthesis was mainly determined by leaf and whole-plant hydraulic traits.
- Mechanism Hydraulic effects on photosynthesis were mediated by stomatal conductance.
- Intervention effect Water stress decreased the leaf area to sapwood area and leaf area to root area ratios.
- Observation The ratio decrease was more evident in GUA8, whose relative growth rate was less affected by water deficit than other genotypes.
- Observation Water-stressed GUA8 plants had better photosynthetic capacity.
- Observation Water-stressed GUA8 plants had higher mesophyll conductance to CO2.
- Observation Water-stressed GUA8 plants had higher foliar N.
