Two soybean cultivars, Santa Rosa and FV-1, were grown in nutrient solution in the presence of high concentrations of Al (24 ppm), CI (1750 ppm) and Mn (25 ppm). Observations, measurements and chemical analyses allowed for the following conclusions to be drawn: (1) symptoms of toxicity are in agreement with those described in the literatura; (2) the detrimental effect obeyed the decreasing order - Mn Al CI; (3) dry matter production by the variety UFV - 1 was relatively more affected by the treatments; (4) leaf analyses do not provide a reliable indication of the sensitivity of the two varieties to the high levels of the three elements in the substrate; (5) Ca/Al ratio in the roots keeps a good relationship with the relative tolerance of the two cultivas to excess Al in the medium.Downloads
