The wide application of rare earth elements (REEs) has led to the accumulation of REEs in soil and plant. Thereby, the effect of Tb3+ on the contents of cytosolic nutrient elements in horseradish was investigated with the synchronous detection technique of scanning electron microscope and energy dispersive X-ray spectrometry. It was found for the first time that the foliar spraying treatment of Tb3+ destroyed the structure of horseradish mesophyll cells, and then changed the contents of the cytosolic nutrient elements in horseradish, especially Ca. The effect of Tb3+ was increased with increasing the concentration of Tb3+. The hydroponical treatment of Tb3+ could not obviously change the structure of protoplast and the contents of the cytosolic nutrient elements in horseradish leaves. The results indicated that the accumulation of Tb3+ in soil and plant leaves displayed the different toxic effect on plant leaves.
