Uptake of scandium (Sc) by wheat seedlings was studied during 6-d germination of wheat seeds in Sc supplemented medium and during 1-week growth of wheat seedlings germinated under normal conditions in soil amended with Sc. The most significant increase in Sc content in the seedlings was observed during germination of seeds in Sc supplemented medium. Transfer of the seedlings to normal soil resulted in a decrease of Sc level in upper plant parts, but Sc concentration in roots remained rather high. Scandium bioaccumulation caused variations in concentrations of Na, K, Ca, and Zn in different parts of the seedlings. The least variations were observed in leaves.
