Hydraulic design of pine needles: one-dimensional optimization for single-vein leaves

Zwieniecki, Maciej; Stone, Howard A; Leigh, Andrea; Boyce, C Kevin; Holbrook, Noel Michele


Single-vein leaves have the simplest hydraulic design possible, yet even this linear water delivery system can be modulated to improve physiological performance. We determined the optimal distribution of transport capacity that minimizes pressure drop per given investment in xylem permeability along the needle for a given length without a change in total water delivery, or maximizes needle length for a given pressure difference between petiole and needle tip. This theory was tested by...[Show more]
