Hydraulic differences between flowers and leaves are driven primarily by pressure-volume traits and water loss.

ABSTRACT: Flowers are critical for successful reproduction and have been a major axis of diversification among angiosperms. As the frequency and severity of droughts are increasing globally, maintaining water balance of flowers is crucial for food security and other ecosystem services that rely on flowering. Yet remarkably little is known about the hydraulic strategies of flowers. We characterized hydraulic strategies of leaves and flowers of ten species by combining anatomical observations using light and scanning electron microscopy with measurements of hydraulic physiology (minimum diffusive conductance (g _min) and pressure-volume (PV) curves parameters). We predicted that flowers would exhibit higher g _min and higher hydraulic capacitance than leaves, which wo
