Considerable variations exist in the phytotoxic response of different plants to cadmium exposure and uptake as observed in experimental and field studies. Quantitative and qualitative variations in comparative anatomy, physiology and biochemistry could be responsible for selective toxicity. Variations in uptake, translocation, sequestration by cell wall, phytochelation or formation of inclusion bodies have been reported in phytotoxic response to cadmium. Earlier studies by Singh et al. (1991) with the aquatic fern Marsilea minuta Linn showed Cd[sup 2+] induced both ultrastructural lesions and metallothioneins at concentrations above 0.5 ppm. However, another aquatic fern, Ceratopteris thalictroides (L.) Brogn was even more sensitive to the basis of this variation, the comparative uptake and translocation of radioactive Cd[sup 109] by these plans was studied. 11 refs., 1 tab.
