Abstract

an experiment was conducted in the laboratory of the Department of Crop Science, Faculty of Agriculture, Omar Al-Mukhtar University, during the 2022-2023 season to study the effect of gibberellic acid GA3 on the germination and growth characteristics of wheat seedlings (Salambo) under salt stress. The experiment was conducted using a completely randomized design (C.R.D) in three replications, the treatments were (soaking wheat grains in gibberellic acid, no soaking) and concentrations of sodium chloride salt (NaCl) (distilled water compared to control, 4000ppm, 6000 ppm, and 8000 ppm). The results indicated that the treatment of soaking grains in gibberellic acid was significantly superior to the treatment without soaking in all the studied traits represented by "germination percentage %, seedling length (cm), root length and shoot length "cm", seedling wet and dry weight "g" and Seedling vigour index ". The results showed highly significant differences between sodium chloride salt concentrations compared to the (Control) treatment, where the germination percentage %, seedling length "cm", shoot and root length "cm", seedling wet and dry weight (g), and Seedling vigor index decreased with increasing salt concentration up to (8000 ppm). The results showed no significant differences in the interaction between soaking treatments and sodium chloride salt concentrations in all studied traits except for germination percentage, where the treatment of soaking grains in gibberellic acid with distilled water (control) recorded the highest values compared to the lowest values recorded when grains were not treated with sodium chloride concentration (8000 ppm).
