Abstract

Plant survival during drought requires adequate hydration in living tissues and carbohydrate reserves for maintenance and recovery. We hypothesized that tree growth and hydraulic strategy determines the intensity and duration of the physiological drought, thereby affecting the relative contributions of loss of hydraulic function and carbohydrate depletion during mortality.
