Phytotoxicity of thallium (Tl) in culture solution. Pt. 2. Effects of Tl(III) on the growth and heavy metal contents of pea and field bean plants

Journal Article:

Abstract

The effects of Tl(NO/sub 3/)/sub 3/ and Tl(III)EDTA on growth and heavy metal contents of pea plants and field bean plants were compared in hydroponic culture experiments. In the presence of Tl(NO/sub 3/)/sub 3/, the essential heavy metals were available to the plants in their ionic forms. When Tl(III)EDTA was present the essential heavy metals were available as chelated complexes. Dry matter production of the pea plants was inhibited to a greater extent by Tl(III)EDTA than by Tl(NO/sub 3/)/sub 3/. The distribution of Tl within the plant was unaffected by the accompanying anion, however an increase of the Tl content of the stems and the leaves was observed in the presence of Tl(III)EDTA. The micronutrients exhibited different interactions with Tl(III). In the presence of increasing concentrations of Tl(NO/sub 3/)/sub 3/ the Mn content of each organ and the Zn content of the roots were lowered, but the Zn content of the stems was increased. Increasing concentrations of Tl(III)EDTA resulted only in a decrease of the Mn content of the roots, but in an increase of the contents of Fe and Mn within the stems, and Fe, Mn, Zn, and Cu within the leaves. The increases may be due to concentration  More>>

Increasing concentrations of Tl(III)EDTA resulted only in a decrease of the Mn content of the roots, but in an increase of the contents of Fe and Mn within the stems, and Fe, Mn, Zn, and Cu within the leaves. The increases may be due to concentration by growth inhibition. In contrast to pea plants, growth of field bean plants was inhibited only by Tl(NO/sub 3/)/sub 3/. The field bean plants retained most of the Tl within the roots independent of the Tl compound in the solution. Chelation of Tl(III) resulted in higher Tl contents of both the roots and the stems, but equal or reduced Tl contents of the leaves. Whereas increasing concentrations of Tl(NO/sub 3/)/sub 3/ reduced the Mn content of each organ as well as the Zn content of the roots and the leaves, Tl(III)EDTA only reduced the Mn content of the roots.}
