Sažetak
The dynamics of the cumulation of iron, copper and sodium with four genotypes of soybean cultivated in the same topographical conditions during three years was followed. Sampling was done in weekly intervals until complete maturity of seed. It was found out that the most intense cumulation took place during the seed development stages III and IV at the time of mostly expressed metabolic activity of the seed. The absolute values of the contents were increasing along with seed maturing and maximums were reached by the end of the stage IV or rather by the beginning of the seed development stage V. Although the dynamics of cumulation regardless of the year of investigation was equal with all the genotypes the analysis of the impact of climatic factors showed that higher precipitation at the period of seed development along with moderate air temperature affected mineral cumulation. Similarly, the highest contents of iron, copper and sodium observed with the genotypes Srtećka and Maksimirka point out that the cumulation of the investigated minerals in soybean seed is affected by genetic particulary.
