Abstract

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.
