Abstract The effects of water deficit on photosynthesis, transpiration, stomata1 conductance, canopy development, and water-use efftciency of broom snakeweed (Gulierrezia sarotlvtre (Pursh) Britt and Rusby) were studied during the spring-summer growing season in pot-grown plants subjected to 5 soil water regimes. Stomata1 conductance was proportionately more reduced by a mild water stress (soil water potential = -0.2 MPa) than were canopy development and photosynthesis. However canopy development was most affected by moderate to severe soil water deficit (
