The hydraulic properties of xylem and phloem differ but the magnitude and functional consequences of the differences are not well understood.
Phloem and xylem functional areas, hydraulic conduit diameters and conduit frequency along the stems of Picea abies trees were measured and expressed as allometric functions of stem diameter and distance from stem apex. Conductivities of phloem and xylem...
Efficient water transport from the soil to the leaves is essential for plant function, while building and maintaining the water transport structure in the xylem require a major proportion of the assimilated carbon of the tree. Xylem transport also faces additional challenges as water in the xylem is under tension and therefore cavitation cannot be completely avoided. We constructed a model that calculates...
