Uptake and Translocation of Cesium in Lettuce (Lactuca sativa L.) under Hydroponic Conditions

Figure 4

The effect of different concentrations of K⁺ and Ca²⁺ on the uptake of different ion in lettuces. (a) Cs-1 mM, leaf;and (b) Cs-1 mM, root; were ion contents in the leaves and roots of lettuces treated with K⁺ under 1 mM Cs treated. (c) Cs-0.1 mM, leaf; and (d) Cs-0.1 mM, root; were ion contents in the leaves and roots of lettuces treated with Ca²⁺ under 0.1 mM Cs treated. (e) Cs-1 mM, leaf; and (f) Cs-1 mM, root. were ion content in the leaves and roots of lettuces treated with Ca²⁺ under 1 mM Cs treated. Notes: the different lowercase letters indicate that significant differences () exist between treatment groups with different Cs levels in lettuce (LSD test).
