Root system hydraulic conductivity in species with contrasting root anatomy

cause the variability in root hydraulic properties that exists among plant species. Previous research suggested that the hydraulic properties of root systems of intact plants could be Key words: Endodermis, exodermis, hypodermis, cortex, described by two parameters: the hydraulic conduc- drought, water transport, root hydraulics. tivity (Lp r ) or the slope of the flow-density/water potential gradient relationship, and the offset or minimum
