Which risk increases when a tall tree's water column experiences significant tensile stress during high transpiration, exceeding its cavitation threshold?

💡 Explanation

Elevated tensile stress from high transpiration can cause xylem embolism via cavitation, because the tension exceeds the cohesive strength of the water column. Therefore, embolism formation is more likely, rather than pressure increases or changes in phloem transport.
