Leaf Length Predicts Twig Xylem Vessel Diameter Across Angiosperms

open access: yesPlant, Cell &Environment, Volume 49, Issue 3, Page 1330-1339, March 2026.
ABSTRACT As plants grow taller, increasing conductive pathlength imposes hydraulic resistance, challenging the maintenance of water transport to leaves. While tip‐to‐base conduit widening along the stem helps mitigate this resistance, theoretical models and empirical data suggest that stem widening alone is insufficient to fully compensate.
