Abstract : A Petri dishes laboratory experiment of RCBD with three replicates was conducted during 2023/2024 winter season at Faculty of Agriculture, University of Kassala, New Halfa, Sudan. to investigate the effect of (GA3) on seed germination and seedling of wheat plant under salinity levels. GA3 treatments are four rates of GA3 G0,G100, G150 and G200 corresponding to (0,100,150 and 200 p.p.m) and three levels of salinity S0, S50 and S100 corresponding to (0, 50 and 100 milimose) prepared from equal equivalents of NaCl. The results revealed that, both of salinity and GA3 treatments affected final germination percentage (FGP%), mean germination time (MGT), Speed of Daily germination (DGS) and index of seedling vigor ( SVI). Increasing GA3 level up to 150 p.p.m increased FGP,DGS,MGT and SVI. On contrast, increasing salt concentration resulting up to 1oo milimoses in decreased of FGP,DGS and SVI. In conclusion, it was concluded that applied of GA3 at recommended levels lessened the harmful of salinity on germination indices and growth of seedling in wheat seeds.

Keywords : Wheat; Gabralline GA3; Salinity, Germination Indices and Seedling Vigor.
