Abstract

This article investigates the relationship between leaf size (LS) and leaf drought tolerance traits—specifically water potential at 50% loss of hydraulic conductance (P50) and hydraulic safety margin (HSM)—across 28 dominant woody species in a subtropical forest in Southern China. The study finds that LS and drought tolerance vary independently, with primary and secondary vein traits (vein diameter and density) strongly correlated with LS, while minor vein traits are significantly associated with drought tolerance. These results highlight the functional importance of vein hierarchy, where lower-order veins influence leaf size and minor veins determine drought tolerance, providing insight into plant adaptation strategies in subtropical forest ecosystems.
