Mineral composition of straw in a number of species from Genera Aegilops, Triticum, and Dazypyrum (Tribe Triticeae) has been established under conditions of different soil pH. Nitrogen (N) content has strongly been influenced by ploidy level and has been maximal in diploids. Wild (T. boeoticum) and early cultivated (T. dicoccum) species surpassed domesticated ones T. monococcum and T. durum, respectively. Maximal phosphorus (P) values were shown in Ae. squarrosa and bread wheat cultivars—Chinese spring and Pliska grown on strongly acid soil. T. aestivum cultivars confirmed partially, previously reported effects of low pH on mineral composition. Diploids and tetraploids showed specific changes in elemental content. Progenitors of common wheat with genomes A (T. boeoticum and T. monococcum) and B (Ae. speltoides), and D. villosum (V) accumulated more manganese (Mn), like the cultivars Chinese spring and Prostor. Ae. squarrosa (D genome) accumulated high aluminum (Al) concentrations in the straw. A iron (Fe): Mn ratio was used to characterize the effect of low pH on element content.
