| Sorghum crops high or medium of tolerant salinity. The adoption of standards early growth indicators election is very important to show the extent of tolerance sorghum to stress salinity and influenced by gene expression. Experiment carried out in 2013 in the lab of Biological Technologies- Agricultural Research Office, according to RCBD design with three replications. Represented by variety (Inqath) as control, elected ((Dewaniya 1, (Dewaniya 2) and varieties entered (Giza113, Giza15, Dorado) and six levels of salinity (0, 2, 6, 10, 14 and 18) Dessie Siemens. The results showed significant in indexes coleoptile, radicle length (77.26,71.666)% sequentially. Giza113 best performers for coleoptile wet weight and radicle indexes (68.51,129.82)% and dry weight index (123.63%). Salinity levels significantly affected in the reduction of all evidence salinity tolerance and the weight of evidence was evidence coleoptile more sensitive to increased levels of salinity after 6 dsm. Giza113 best indicators of salinity tolerance. Index dry weight of rootlet (180.24 %), index total wet and dry seedling (136.42, 124.60)% sequentially, for continuing to increase the weight with high salt levels up to 10 dsm. | ||
