Which risk increases when a tree experiences reduced stomatal conductance?

💡 Explanation

Xylem cavitation increases because reduced stomatal conductance hinders transpiration influencing the cohesion-tension mechanism. Lack of sufficient water movement increases tension within the xylem, therefore creating a risk of forming cavitation bubbles, rather than reduced photorespiration or enhanced water absorption.
