Different concentrations (0.1, 0.2, 0.5 ppm) of Cadmium were supplied to the nutrient solution of liquid hidroponic culture of Phaseolus vulgaris L. var. Contender. After 21 days of plant growth the levels of Putrescine (Put), Spermidine (Spd) and Spermine (Spm) were determined in roots, stem, primary leaves and trifoliate leaves. Stem and trifoliate leaves of Cadmium treated plants show a senescence state indicated by a lower values of Put and Spd than nontreated plants. A stress situation is present in roots of all treated plants indicated by a higher values of Put and Spd than nontreated plants, with a good inverse correlation between polyamine levels and Cadmium concentrations. In primary leaves 0.1 ppm and 0.2 ppm of Cadmium produce a stress situation, but 0.5 ppm of Cadmium produces a senescence state.
