It is a main source of nitrogen in the soil. The objective of this research was to estimate Vicia faba response to zinc ion elevation in nutrient media. The investigation in liquid culture media with elevated concentration of zinc (control, 100, 200, 400, 600 and 800 µmol L-1) showed that thetested species can be used as indicator plant, the plant showed stability against zinc toxicity, determined by their ability to germinate and grow as well as the production of access free proline 21 times more than control at 800 µmol ZnSO4L-1 of media. Along with the accumulation of zinc in plant leaves (up to 542.8 µg g-1 dry weight of plant leaves at 800 µmolZnSO4 L-1 of media), these results suggest that Faba bean plant Vicia faba is a potential phytoremediation plant for moderately contaminated areas with zinc.
