Supplemental Data. Soil Water Content (SWC, As % with Respect to Control Values)

Supplemental data. Soil water content (SWC, as % with respect to control values), pre-dawn leaf water potential (PD), stomatal conductance (gs) and intrinsic water use efficiency (AN/gs) for the eleven selected species under different irrigation treatments: control (CO), mild water stress (MiWS), moderate water stress (MoWS), severe water stress (SeWS) and re-watering (RW). Values are mean ± SE of four replicates.
