Conceptual framework of resprouts rapid regrowth of desert shrubs. Under the control condition, the root water supply (S) equals canopy water demand (D). Disturbance caused the decreased canopy water demand, thus causing the imbalance between water supply and demand. Higher root water supply relative to low canopy water demand induced higher leaf water potential (Ψleaf) and hydraulic conductance (Kleaf), which supports higher stomatal conductance (gs) and ultimately contributes to higher photosynthesis rate (Asat) and rapid resprouts growth
