| Abstract | ||
| The study included two separate practical experiment. The first one was conducted at the laboratory of germination in the centre of general institue for testing and Assuring Seed Branch of Salahaldeen to study the influence of three concentrations of sodium chloride (0, 50 and 100Mu) and three irrigation periods :( continuous irrigation, once every four days and last every six days) on germination and seedling growth of Allium cepa . The second experiment included study the influence of the aforementioned concentrations of the sodium chloride and the irrigation periods in some of the features of shoot growth to the onion by applying the vases test after six weeks of seeds germination. The increasing concentrations of sodium chloride and irrigation periods led to a significant decrease in most of the studied features of the plants while they led to increase of the Proline concentration in the plant’s leaves and the percentage of cell membrane damage in comparison with the treatment’s control . The combination of salt at 100 Mu. and irrigation every six days was the most negatively effective in all physiological parameters. | ||
