Measuring the amount of Magnesium and Potassium in the grains of different parts of wheat cluster during the growth period

To select the best seeds in wheat cluster (Triticum aestivum L. var. PBW-343), the amount of magnesium and potassium in different parts of the grain clusters were measured. The spikelets of the grain cluster were divided into basal, central, and apical parts and then the seeds of the spikelets were divided into basal (bold) and apical (small) parts. The changes in the amount of magnesium and potassium during the fourteenth and the twenty-eighth days as well as the maturity period were measured. Magnesium and potassium concentrations were at the lowest level during the fourteenth day. The highest amount of magnesium and potassium reservations in the cluster was measured during the maturity period. The amount of magnesium during the experiment was higher in the basal seeds of the central spikelets of the cluster in comparison to the seeds of the other parts. The results indicated that since there was no significant difference between the basal seeds of the central and the basal spikelets, they can be placed in one group. Similarly, the amount of potassium was higher in the basal seeds of the central spikelets of the cluster in comparison to the seeds of the other parts and given that there was no significant difference between the basal seeds of the central and basal spikelets in this regard, they can be placed in one group. The results of this experiment revealed that a wider range of crops can be used for corrective works in comparison to the work of other researchers.
