Gibberellic acid (GA3) is one of the most important plant growth regulators which decrease the e ffect of salinity A laboratory experiment was conducted to study the effect of Gibberellic acid (GA3) and some salinity levels on the germination of barley seeds, using a completely random design in three replications, where the seeds were treated before planting with Gibberellic acid at a concentration of 300 ppm (soaking for 24 hours), compared to soaking in distilled water (control) under the influence of different concentrations of NaCl salt (4000, 9000) ppm compared with control. The results of variance analysis (ANOVA) showed extremely significant (p < 0.05) when soaking barley seeds in Gibberellic acid (GA3) compared to control under different levels of NaCl concentration, as there was a positive effect on barley germination and root system where usin g Gibberellic acid such as germination energy (%), laboratory germination (%), germination force%, weight 100 feathers gr., weight 100 root gr., length feather (cm) and length roots (cm).

The variance analysis results of laboratory germination experiments as well as in field experiments under rain-fed conditions showed that there were significant differences (P < 0.05) in the mean of most of the studied quantitative traits: germination quality such as germination force (%), germination energy (%), and laboratory germination (%). Leaf area (cm2 ), root spread, stem diameter (cm), as well as wet and dry weight under the influence of the different concentrations of colchicine.
