Summary
Wheat genotypes from various Triticum L. genus species (T. dicoccoides Körn, T. durum Desf, T. spelta L. and T. aestivum L.) were analysed by stereological analysis in order to explore the existence of inter-species differences and similarities in anatomical characteristics of wheat flag leaf tissue. The genotypes of the tetraploid species did not differ significantly among themselves in the volume density of the analysed tissues of the flag leaf. Among the hexaploid species, the results showed highly significant differences in volume density of the photosynthetic tissue and volume density of the mechanical tissue; and significant differences for the volume density of the vascular tissue. The analysis of the main vein of the flag leaf showed smaller volumes of the vascular tissue in hexaploid species — of the phloem and parenchyma of the main vein. The analysed species showed the greatest difference in the volume of the main vein, the parenchyma of the main vein and the mechanical tissue. When compared to the volume and volume density of the xylem of the main vein, the tetraploid species had greater volumes and volume densities of the mechanical tissue of the main vein. With hexaploid species the results were reverse.
