Vascular-plant xylem transport capacity, drought-induced and wound-associated embolism, hydraulic conductivity loss, cavitation resistance, and the evidence limits surrounding embolism repair mechanisms.
Visual lesson 10
Hydraulic disruption & embolism
Understand how excessive xylem tension, wounding, freeze-thaw events, or other disruptions can introduce gas into conduits and reduce hydraulic conductivity, while avoiding unsupported cultivar-specific thresholds.
