Which outcome commonly occurs when leaf transpiration rates greatly exceed water availability, impacting vascular plant water potential?

💡 Explanation

Xylem embolism occurs because excessive transpiration pulls water under tension, forming air bubbles that disrupt the cohesion-tension mechanism; therefore xylem transport fails, rather than ABA increasing or stomata remaining open and so exacerbating water loss.
