Which reduction in leaf water potential minimizes xylem embolism?

💡 Explanation

Water stress causes increased cavitation due to negative xylem pressure; therefore, elevated root pressure promotes refilling via positive pressure flux, rather than stomatal changes because these affect water loss or vessel dimensions without addressing xylem.
