| Abstract | ||
| The salt is the most important a biotic stress which adversely affect the germination of seeds of sorghum and stimulate, the emergence of the embryo and the process of assembling the dry matter of seedlings in the early stages, which are affected by the gene expression. Implemented a factorial experiment in 2013 in the laboratory of biological technologies-Agricultural Research Office, accordance with the RCBD design with three replications. Used six genotypes included two selectable (Diwaniya 1, Diwaniya 2) and varieties entered (Giza113, Giza15, Dorado) with control (Inqath), and six levels of salinity (0, 4, 8, 12, 16 and 20) ds.m-1. To study the the germination percentage after 24, 48 and 72 hours and 10 days after. As it outperformed all genotypes in germination percentage at (0 ds.m-1) after 24, 48 and 72 hours and after 10 days, but decreased with the continued stress and salt concentration, especially at the level of 20 ds.m-1. Gizaf113 gave a max weight of coleoptil, radicle, plumule length and fresh weight total (0.843 g) and (0.78 g) (5.467 cm) and (1.749 g) respectively, at 0 ds.m-1. All genotypes Decline at 20 ds.m-1 and gave lower values for all traits. | ||
