Abstract

URANIUM as a natural radioactive heavy metal, widely disperses throughout the earth's crust. In many cases, the natural abundance has been re-distributed due to anthropogenic activities, resulting in radionuclide contamination in groundwater and surface soil. A pot experiment had been conducted in the Agricultural College Research Greenhouse, at the Ferdowsi University of Mashhad under the controlled condition. The effect of six levels of URANIUM (0, 50, 100, 250, 500 and 1000 mg U kg-1) on physiological characteristics and chlorophyll contents in sunflower and soy bean were studied in a completely randomized design as a factorial experiment with three replications. Plants were harvested after 40 days and before the reproductive stages. Root and stem length, root dry weight, stem dry weight, biomass and chlorophyll contents were determined. The shoot and root length, fresh and dry mass as well as leaf area and chlorophyll contents showed a significant negative correlation with the applied URANIUM concentrations. The influence on plant growth was also measured in terms of TOLERANCE INDEX TI and GRADE OF GROWTH INHIBITION GGI. The results showed that TI increased and GGI decreased with the applied URANIUM concentration. Biomass and tolerance of sunflower during the experiment on higher URANIUM concentrations showed that sun flower is more resistant against URANIUM toxicity.
