Abstract

The effects of two chemical aluminum (Al) species - monomeric and polymeric - on the growth of maize plants, Zea mays L. (Poaceae), cultivated in nutrient solution at low ionic strength were studied. The shoot dry matter production and the principal root growth were affected by the Al doses and species. The Al toxicity effects were more evident on the roots than on the shoot. The growth of the secondary roots was affected by Al doses. The growth of secondary roots was reduced by 80% in relation to the control when the Al activity in solution was 3.9 µM. The toxicity level of both Al species was similar
