Mean Zn stable isotope compositions (δ⁶⁶Zn) versus mean mass fractions (f) of Zn in leaves, stems and roots relative to the total plant Zn inventory for NA 702 plants treated with 0 µmol L⁻¹ (yellow, n = 3), 5 µmol L⁻¹ (green, n = 2), and 20 µmol L⁻¹ (blue, n = 1) CdCl₂. The error bars denote the 2SD precision determined for multiple analyses of the Zn isotope standard that bracketed the sample runs. The blue line denotes the δ⁶⁶Zn value of + 0.51 ± 0.06‰ for the ZnSO₄ that was added to the hydroponic solutions.
