Distriblltion of alunlinum (Al) wlthin plant components and Al-induced changes in cell wall polysaccharides in root tips of Eucalyptus camaldulensis <\/I>Dehnh. seedlings were compared with those of Melaleuca cajuputi <\/I>Powell. In E. camaldulensis, <\/I>0.5 mm Al (pH 4.2 for 40 d) reduced plant đry weight by 50% , increased callose concentration in the root tips and induced leaf necrosis. In comparison with M. <\/I>cajuputi, Al concentrations were higher in roots and leaves of E. camaldulensi <\/I>on both a fresh weight basis and in the cell sap, but were lower in the cell wall. Al increased pectin, hemicellulose and cellulose concentration in the cell walls of E. camaldulensis <\/I>root tips. Al-inđuceđ leaf necrosis and growth reduc tion in E.camaldulensis <\/I>is discusseđ in the context of potentiany toxic concentrations of Al in plant tissue and changes in polysaccharide content which could reduce water and nutrient uptake anđ cell wau extensibility in roots.<\/SPAN><\/SPAN><\/FONT>
