"We investigated how leaf hydraulic conductance (K-leaf) of loblolly pine trees is influenced by soil nitrogen amendment (N) in stands subjected to ambient or elevated CO2 concentrations (CO(2)a and CO(2)e, respectively). We also examined how K-leaf varies with changes in reference leaf water potential (Psi(leaf-ref)) and stomatal conductance (g(s-ref)) calculated at vapour pressure deficit, D of 1 kPa," investigators in the United States report.
"We detected significant reductions in K-leaf caused by N and CO(2)e, but neither treatment affected pre-dawn or midday Psi(leaf). We also detected a significant CO(2)e-induced reduction in g(s-ref) and Psi(leaf-ref). ...
