Effect of aluminum on the growth of wheat, rye, and triticale

The effect of aluminum (Al) on the growth of wheat (Triticum aestivum L.), rye (Secale cereale) and triticale (Triticale hexaploide Lar.) has been investigated. Aluminum concentration greater than 5 mg/L was required to inhibit the growth of the wheat roots and shoots even on the 5th day. Aluminum concentrations up to 10 mg/L did not affect the forming of root and shoot biomass in rye seedlings. Moreover, the same concentrations stimulated root elongation and forming of root and shoot biomass in triticale plants on the 20th day. It was concluded that triticale seedlings were less sensitive than rye and much less sensitive than wheat to the effects of Al.
