root, stem, biomassAbstract
he effect of cadmium on the growth and biomass gain in bean plants (Vicia faba L.), developed in hydroponic culture and exposed to a CdSO4 concentration of 0.112 ppm, was evaluated; The bioaccumulation of the metal in root, stem and leaf was also determined. The results show that the cadmium generated a decrease in the growth of the vegetative part, in the length of the root and in the production of biomass in the plants subjected to the contaminant; the root was the site of greatest bioaccumulation followed by the leaves and the stem. The roots showed a darkening and thickening. Responses to the pollutant can be a tool for environmental monitoring studies.
