Background Optimum remuneration of seed priming of Brassica napus L. with jasmonic acid were studied under salinity stress. Method Seeds of Brassica napus L. were primed with jasmonic acid (JA) at four levels (0, 6, 9, 12 M). Then primed (P) and non-primed (NP) seedlings were supplied with different concentrations of saline solutions consisting of 0 (control), 140, 160, 180 mM NaCl. Results The results showed that the JA reduced the toxicity of salt stress on seedling growth by accumulating proline content and by reducing electrolyte leakage and lipid peroxidation. Pre-treatment of jasmonic acid was found to be significantly effective in increasing the content of protein. Conclusions The present study revealed that under salinity seed priming with JA could be used as a method to improve productivity in Brassica napus. However, further studies are needed to investigate the effects of JA priming on later growth and development of this crop.
