Summary
Pressure-induced non-linear water flow across plant roots was analyzed theoretically. The double-canal model of radial water transport shown lately explained accurately the observed non-linear water flow in maize roots. The driving force rather than the hydraulic permeability caused the non-linear flow of water. The conclusion was drawn that non-linearity in pressure-induced water flow was an inherent property of the apoplast canal system in roots. Net solute transport plays a primary part for water transport.
