Abstract Laboratory and pot trials were conducted to study germination performance of rapeseed ( Brassica napus L., genotype Excalibur) under NaCl salinity after seed priming with 20 mM for 24 h. In the laboratory trial, levels 80, 160, 240 reduced percentage by 14, 56, 80 points, respectively compared non‐saline control. lowered detrimental effect salt stress on promoting from 81% 85% mM, 39% 68% 160 15% 56% (maximum alleviation). Furthermore, increased tolerance index vigour seedlings as control seeds. Relative water content leaves was decreased increasing salinity, showing limited availability a loss turgor in leaves. decrease relative salinity. Concerning level dry weight 80.9% non‐primed seeds 55.8% primed improved mean productivity 1.26 times harmonic 1.98 Salinity rapeseed, whereas early growth saline environment. The method needs be examined selection relevant genotypes range conditions.
