Wheat seedlings (Triticum vulgare L.)var. Piratiní susceptible to aluminum toxicity (crestamento), and var. Colônias, tolerant to aluminum, were grown in nutrient solution with divided root system. One part of the roots were grown in nutrient solutions lacking phosphorus and containing from 0,0 at 6,0 ppm of aluminum while the other part of the root system was grown in nutrient solutions containing all nutrients and 25 uCi of 32P as tracer. In both varieties, the aluminum concentration in leaves did not effect the translocation of phosphorus 32P to the new leaves. Both varieties showed a different P/Al relations in leaves, seem and roots.
