Effects of Uranium on Growth Performance in Vigna unguiculata (L.)

Abstract

The aim of this article is the determination of uranium concentration in shoots and roots of barley (Vigna Unguiculata.), grown on so growth and development. The soils was contaminated with different doses (12.5μM to 200 μM) of uranyl nitrate. Vegetative as well as Fruiting stages indicated uranium phytotoxic effect on plant height, yield, and germination of seeds, shoot –root fresh weight as well as shoot-root dry weight. This effect was stronger on the plants grown at high concentration in comparison with those grown at lower concentration. Soil properties determined the tolerance and accumulation of U in plants.
