The role of the bole: Constraints on the remobilization of stem non‐structural carbohydrates under experimental carbon limitation

Abstract Plants store non‐structural carbohydrates (NSC) for remobilization when carbon (C) demand exceeds supply. However, large trees may not readily remobilize stored NSC across longer distances, limiting C availability for functions like growth. Furthermore, whether NSC availability limits physiological processes like defence and hydraulic function remains poorly understood, limiting our ability to predict when C limits growth and survival. To test whether organs remobilize C over long dista
