Abstract

The study was conducted in the fall season of 2020 to know the effect of soaking yellow corn seeds with different concentrations of gibberellin on the ionic balance of yellow corn under salt stress. The study showed that the use of different types of salt water led to a significant increase in the amount of potassium, calcium, sodium and chloride absorbed in the plant tissue and that the seeds were soaked with gibberellins at concentrations of 300, 600 and 900 mgGA3L-1, It led to a significant increase in the absorption of potassium and calcium ions, compared to a significant decrease in the absorption of sodium and chloride. Also, expressing the percentage of ions to each other is better than expressing their absolute quantity, as increasing the percentage of potassium or calcium to sodium. It increases the permeability of cell membranes, improves the osmotic pressure, builds protein, photosynthesis, controls stomata work, and thus increases plant resistance to endure salt stress.
