  1. N: number of roots, RFW: root fresh weight, RDW: root dry weight, RL: root length, RS: root surface, RV: fine root volume.
  2. The data represent all the roots of the non-inhibited plants (control) and inhibited plants (HgCl2). Values are means and standard deviations.
  3. aFine roots are the smallest diameter class (0 – 0.5 mm) determined by the WinRHIZO analysis.
  4. bK+ fluxes are for HgCl2 treated plants but are also expressed in percentage of the controls (values in parenthesis).
