Relationship between 137Cs concentrations among compartments (needles and roots) in control (open symbols) and K-fertilised (grey symbols). Both axes are shown by logarithmic scales. The seedlings were sampled in October 2015 at the end of the second growing season. Two linear regression lines were drawn for control (solid line) and K-fertilised (dotted line) because a significant interaction between logarithmic root 137Cs concentration and fertilisation treatment was observed in the regression analysis (nested ANCOVA, p < 0.05).
