Plant tolerance to salinity involves complex "decision making" for the plant to maintain turgor in an energy-effi cient way without cIn the halotolerant Beta vulgaris, the capacity to surpass salinity implies a transition to a new steady-state that is characterized by onand the change of the root hydraulic conductivity from high to low values after a threshold NaCl concentration value. In view o topologies of the water paths are necessary to explain and interpret the tolerance to salinity during the transition to the new steady statopologies including new elements to the hydraulic circuit. Our objective is to explain the mechanisms of water movements on Be changes in the environment’s salinity in stress conditions. For this, we fi rst work in model formulations as well as the identifi cation account Beta vulgaris background and the electric circuit theory. Finally, we selected those topologies and elements which best adjdata. Our challenge is to integrate the information into a topological model that encompasses the dynamics of the water passage aroot in terms of tolerance to saline stress concerning the control condition.
