1 INTRODUCTION Water is transported through the xylem from the soil to the evaporating surfaces in the leaves. This upward movement of water against gravity is driven by a water potential gradient between the soil and the leaves (Dixon & Joly, 1895). During drought, the formation of embolism blocks the water flow through xylem conduits.
