Water status, drought responses and growth of Prosopis flexuosa trees with different access to the water table in a warm South American desert

Carla V. Giordano*, Aranzazú Guevara, Hernán E. Boccalandro, Carmen Sartor and Pablo E. Villagra*IADIZA CCT-Mendoza [email protected]

Daily leaf conductance to water vapor (gl) in representative valley and dune adult trees with contrasting pre-dawn leaf water potentials (ΨwPD) during a dry (a) and wet (b) period. c) and d) Daily gl and Ψw in the valley tree. Symbols represent single measurements; the vertical dashed line indicate local solar noon.
