Abstract
Estimates of root hydraulic conductivity (Lp), morphological and structural observations were obtained in olive trees trained in 8 liters pots with two substrates: sand-clay-loam and loamy-sand.
Water flow through roots was estimated non-destructively on whole trees by a semi-closed gas-exchange measurement system.
Transpirational flow of each tree was varied by imposing different environmental conditions within the cuvette.
Xylem water potential of non-transpiring leaves inserted in basal shoots was used as a best-estimate of water potential gradient between root and soil.
Results were expressed on a unit-root-length basis.
Root hydraulic conductivity (Lp) was higher in the more compact substrate.
Consequently, at the same level of transpiration flow, trees grown on the looser substrate were subjected to lower root water potential and more exposed to conditions of water deficit.
Since structure, degree of branching and average diameter of the roots were not significantly affected by substrate, differences in Lp cannot be attributed to a different amount of root surface area.
Hence, effects of substrate on Lp should be attributed to other factors (membrane permeability, degree of suberization of fibrous roots), which were not measured in this experiment.
