title: Physiological significance of the structure and components of the apoplast canal system for water absorption in plants.
abstract: The non-linear differential equation that describes the coupling between water transport and solute transport in the apoplast canal system in plants was proposed by Katou and Furumoto in 1986. In the present paper, we analytically solved the equation in order to find the law describing the canal system. In the canal system, water transport is regulated linearly by solute transport under physiological conditions. The approximate solution of the differential equations defines the conditions of the structure and components of the apoplast canal for optimal water absorption. Water absorption during cell elongation in plants requires that the apoplast canal be composed of a cell wall with an appropriate diffusion coefficient for solute.
