Seed Priming Enhances Seed Germination and Morphological Traits of Lactuca sativa L. under Salt Stress

Seed germination is the stage in which plants are most sensitive to abiotic stress, including salt stress (SS). SS affects plant growth and performance through ion toxicity, decreasing seed percentage increasing time. Several priming treatments were used enhance under SS. The objectives of this study (1) identify shorten emergence period, (2) evaluate against SS, (3) induce synchronized germination. Salt-sensitive ‘Burpee Bibb’ lettuce seeds treated with 0.05% potassium nitrate, 3 mM gibberellic acid, distilled water. All primed non-primed subjected 100 sodium chloride (NaCl) or 0 NaCl (control). seven-day experiment, arranged a complete randomized block design four replications, was conducted chamber maintained 16/8 h photoperiod (light/dark), 60% relative humidity, day/night temperature 22/18 °C. result indicated that hydro-primed (HP) better Similarly, fresh mass (FM) dry (DM) cotyledon, hypocotyl, radicle highest HP regardless Electrolyte leakage lowest lettuce, while other methods increased membrane permeability, leading osmotic tissue damage. Overall, hydro-priming can be good method for synchronizing FM DM by creating least toxicity
