Figure 3

137Cs concentrations in the cypress seedlings sampled at control plots (open bar) and K-fertilised plots (grey bar). Asterisks (*) indicate that samples obtained at the same time showed significant differences between treatments (nested ANOVA, p < 0.05). All stem samples at pre-planting showed less values than the detection limit despite long (24-h) measurements. Subsequently, the mean of detection limits was shown.
