Accumulation of iron, copper, manganese and nickel during maize grain maturation
Dynamics of the accumulation of iron, copper, manganese and nickel, as well as their relationships with total ash, crude proteins and total dry matter during maize grain maturation were investigated. The investigation was carried out on normal maize hybrids grown under the same topographical and agrotechnical conditions. The amounts of particular microelements in the fresh grain matter increased significantly up to a late stage of dough maturation. The dynamics of their accumulation correlated positively and significantly with deposition of total dry matter, total ash and crude proteins, and were consistent with biological needs of the maize grain during development. The amounts of microelements expressed on a dry matter basis decreased significantly in a late stage of milky grain maturation. Further fluctuations were not significant. The correlation between particular microelements during grain maturation was positive and significant, as well as the correlation of particular microelements with crude proteins and total ash in the grain dry matter.
