In this study is tested the variability and heavy metal (zinc) hiperaccumulation potential in Phaseolus vulgaris plants, as a modality for the reduction of the danger represented by zinc, through the reduction of the heavy metal mobility and biodisponibility in soil through phototherapy. There were effectuated studies on the plants treated with increasing Zn concentrations, confronted with visual symptoms, biomass production, and heavy metal concentration in plant’s organs. Tolerance for increased zinc concentrations is quantified with the help of three parameters as are biomass (aerial parts and roots), main root length, and the influence of the zinc quantity from treatment solution on the accumulation of some micro and macroelements in plant.
