RESUMO
A pot experiment with six levels of cadmium [0, 1, 3, 5. 7 and 9 mg kg[-1] soil] conducted to investigate the effects of cadmium on the growth of Amaranthus [Amaranthus tricolor L.] a popular leafy vegetable crop in Bangladesh, and Cd accumulation in it. Plants were harvested at 30 and 45 days after sowing [DAS]. Plant height and biomass production of shoot and root were significantly affected by Cd treatments and there was a depression of yield due to increased Cd application. Cadmium accumulation in Amaranthus and the shoot: root ratio of Cd increased with increasing Cd concentrations in soil. The increase of soil contamination level led to a decrease of bioaccumulation coefficient in shoot and root at both the stages. The capacity for Cd accumulation in edible parts of Amaranthus with the absence of any visual symptoms indicates a potential danger for human consumption
