•In response to saline and osmotic stresses, PA increased by PLD and diacylglycerol kinase activities.•NaCl and mannitol stresses increase the proline accumulation.•In response to saline and osmotic stresses, the roots exhibited a reduced growth.•Saline and osmotic stresses decrease the GA3 and ABA...
