Table 2 Summary parameters for the 13 woody karst species from southwestern China examined in this study. Minimum leaf water potential (Ψmin, MPa), photosynthetic rate (Pn, μmol∙m− 2∙s− 1), stomatal conductance (gs, mol∙m− 2∙s− 1), leaf specific conductivity (Kl, kg∙m− 1∙MPa− 1∙s− 1), xylem tension at 50% cavitation (Ψ50, MPa), leaf specific conductivity at noon (Klnoon, kg∙m− 1∙MPa− 1∙s− 1), loss percentage of Kl at noon (Loss, %), maximum quantum efficiency of photosystem II (Fv/Fm), and hydraulic safety margin (Margin, Mpa) were assessed for each species. Standard errors were shown in parentheses
From: Do karst woody plants control xylem tension to avoid substantial xylem cavitation in the wet season?
