Osmotic and elastic adjustments in cold desert shrubs differing in rooting depth: Coping with drought and subzero temperatures

Physiological adjustments to enhance tolerance or avoidance of summer drought and winter freezing were studied in shallow to deep-rooted Patagonian cold desert shrubs. We measured leaf water potential (ΨL), osmotic potential, tissue elasticity, stem hydraulic characteristics, and stomatal conductanc...
