Summary
The effects of A1 on the growth and mineral composition of different cultivars of triticale (X Triticosecale, Wittmack), wheat (Triticum aestivum L.) and rye (Secale cereale L.) growing in 1/5 strength Steinberg solutions containing 0 or 6 ppm A1 were evaluated after 32 days. Aluminum increased the concentrations of P and K in the roots and K in the tops of most of the cultivars tested. A1 tolerant triticale retained a lower concentration of Mg in the roots and tops than the A1 sensitive triticale, when subjected to A1 stress. In addition, A1 treatments resulted in smaller increases in root P for the A1 tolerant triticale than for the A1 sensitive cultivars.
The concentration of root Ca and P of the A1 tolerant wheat cultivars were significantly below that of the more sensitive plants. Aluminum tolerance in rye appeared to be associated with lower Ca and higher Mg concentrations in the tops. The accumulation of P and A1 in the roots was characteristic of sensitivity in triticale, wheat and rye.
