The effects of irrigation treatments on 2-year-old, split-root containerized ‘Gale Gala’ apple leaf pre-dawn water potential (A), stomatal conductance (B), net assimilation (C), and water use efficiency (D). Data are expressed as a percentage of control (C). On DOY 215, PRD50 and DI50 were changed to PRD100 and Control treatments, respectively. Vertical dashed lines signify switches in irrigation between PRD ‘wet’ and ‘dry’ compartments. Asterisks on the bottom represent significance at P < 0.05. Each point is the mean of three replications (n=2).
