Popis:	Distribution of iron (Fe), manganese (Mn), and zinc (Zn) in mature grains of maize (Zea mays L.) of 25 genotypes was studied. The highest concentrations of micronutrients were found in the seed coats and scutellum, while the lowest were found in the endosperm. The endosperm, scutellum, and seed coats contained between 60–80%, 15–35%, and 8–12% of the total grain micronutrients, respectively. Mobilization of Fe, Mn, and Zn from the scutellum and endosperm was studied in four genotypes of maize during 3–120 h of germination and early seedling growth. Variation in original concentrations in the scutellums of the genotypes exceeded that observed in the endosperms. Genotypes were separated into several groups with high-Fe (144–168 μg g−1) and high-Zn (89–94 μg g−1) scutellum (cvs. Brewero yellow, Corriente de gallina), high-Mn (40–42 μg g−1) scutellum (cvs. Pusey blond, Brewero yellow), low-Fe (107–110 μg g−1) and low-Zn (76 μg g−1) scutellum (cvs. Pusey blond, Oregon grewn), and low-Mn (33–36 μg g−1) scutellu...
