Direct and residual effects of cadmium on the growth and elemental composition of Arabidopsis thaliana
Experiments were conducted to determine the direct (first generation) and residual (second generation) phytotoxicity of a range of cadmium concentrations on Arabidopsis thaliana. Plants were grown under greenhouse conditions in double-container, vermiculite-hydroponic plot-culture systems. First generation plants were continuously exposed to nutrient solutions ranging from 0 to 100 micrometers CdCl/sub 2/. Biomass in the first generation plants decreased in response to nutrient solution containing increasing Cd concentrations. The 100 micrometers Cd treatment significantly reduced rosette, raceme and mature seed biomass. The progeny from the first-generation plants revealed no significant residual effects as far as growth and elemental composition are concerned.
