mainly endogenous content of IAA, ABA and proline have great role in salt tolerance.

increasing with increase in salt treatment. Abscisic acid (ABA), auxin, cytokinins (CK), brassinosteroids (BRs), jasmonates, gibberellin (GA),  salicylic acid (SA) and triazoles (TR)and ethylene for alleviation of salt stress in plants. all have different different phenomena for tolerating salt stress. 

 Mr. Pepe Ibrahima, 

wiil u tell me on which crop u working now?

I work in the revegetalization of salted lands using moderately salt-tolerant species. Among them, the plants Casuarina equisetifolia and C. glauca are pioneer species capable of developing in salted soils
