Abstract

Leaf diffusion conductance much increased when Xanthium strumarium (C₃), Atriplex prostata (C₃) and Flaveria pringlei (C₃), F. sonorensis (C₃/C₄), F. floridana (C₃/C₄), and F. trinervia (C₄) plants were grown under relatively high (28 kPa) ambient oxygen. This phenomenon, which increases sensitivity to water stress, could have adversely affected vegetation during the late Cretaceous, high O₂ episode.
