Effect of salinity on germination characters and seedlings parameters of Egyptian flax cultivars growing in Nyiregyhaza

In the recent years using non-traditional sources, i.e. saline water in irrigation becomes essential. Overcoming the toxic effects of salinity stress and improving salt tolerance is consider one of the challenges for enhancing germination, seedling characters and biochemical analysis. Therefore, a laboratory experiment was conducted to study the response of seven Egyptian flax cultivars i.e. (Giza 9, Giza 10, Giza 11, Giza 12, Sakha 2, Sakha 5 and Sakha 6) germinated under five salinity stress i.e. (control, 3, 6, 9 and 12 dS m−1) at Research Institute of Nyiregyhaza using Factorial Experimental in Randomized Complete Block Design (RCBD) with four replications. The following results were recorded: Tested Egyptian flax cultivars significantly varied for germination characters, seedling properties and chemical analysis. Giza 11 exceeded recorded the maximum values of germination and seedling characters, potassium and proline content compared with the other studied cultivars. Increasing salinity stress up to 12 dS m−1 significantly affected germination characters, seedlings parameters and chemical analysis. In general, Giza 11 cultivar substantiated best at high level of salinity stress compared with other studied cultivars. Furthermore, produced the lowest values of Na+ content.
