Values are mean hydraulic conductances ± SD (n=12). Values in parentheses are the hydraulic conductance expressed as a percent of the control, acid-etched values that were defined as 100%. Groups identified by the same superscript are not significantly different (from Bouillaguet et al.20, with permission).
