摘要
Salinity stress can be mitigated by using the physiological seed enhancements. Kharchia 65 (salt tolerant) and PI.94341 (salt sensitive) genotypes were evaluated under salt stress (20 dS/m) by various priming treatments, that is hydropriming and halopriming (50mmol, KCl and NaCl) in a pot study. Experiment was conducted in completely randomized design under factorial arrangements with three replications. Priming agents improved the final emergence percentage (FEP), emergence index (EI) and reduced the mean emergence time of both wheat genotypes under normal and saline conditions as compared to non-primed seed. Priming treatments elicited the efficiency of wheat seedlings by increasing both Fv/Fm and Ft under both normal and salt stress conditions which were strongly linked with low Na+ and high K+. In conclusion, all three priming agents effectively nullified the deleterious effects of salt stress by improving seed emergence and triggering the physiological attributes of wheat.
