The objective of this work was to assess different Al leveis in nutrient solution to select Al tolerant tinira and red clover to ticid soils and to compare tilem in different Al leveis. Eight Al leveis were tested: 0; 0,2; 0.3; 0,4; 0,6; 0.9; 1,2; 1.5 mg/L in nutrient soiution continuously aerated, with 10 70 of original ionic strength and phl 4.5. The length of roais and shoots were measured to assess the response to the AI soiution. The evaluation of the moi growt h was more effective than that of the shoot in selecting Al tolerant plants. The red clover showed a better root growth up to 0.6 mg/L AI. The best Al levei to select both species was between 0,4 and 0.6 mg/L Al. The seiection method used was fast (13 days) and simple.
