| Abstract | ||||
| Application of some chemicals such as salicylic acid, chitosan and hydrogen peroxide as pre-sowing treatment could improve its performance under different salinity levels. Laboratories and pot experiments were carried out during 2015 year. Wheat seeds were treated with plant stimulants (0, 50, 100, 150 ppm) and then germinated under different salinity levels namely (0,100,150 and 200 mMol of NaCl). The present study aimed to determine the impact of salt stress on wheat seed viability to screen out the best seed stimulants resistant to the various changes associated with the plants under different salinity levels. The main results showed that treating wheat seed before sowing with chitosan produced the vigours seedling and its length, and dry weight, vigor index, germination percentage, germination energy, as well as proline content as compared with treating the seed with salicylic acid and hydrogen peroxide. Increased salinity levels caused great reduction in seedling length, and its dry weight, vigor index, germination percentage, germination energy, germination rate and pot emergence as compared with control, except for proline content. The results revealed also, that the interaction effect between salinity treatments, seed germination stimulants and concentrations was significant for all studied traits. Furthermore, using chitosan followed by salicylic acid and hydrogen peroxide was the most effective treatment to protect wheat seed cv Gemmiza 9 during germination from adverse salinity effect . | ||||
