Abstract:

 Description of the subject: Crops are subjected to drought at different growth stages and cause considerable yield loss, thus threatening global food security. Hormonal seed priming can markedly improve the germination and the growth on wheat under abiotic stress. 

Objective: The aim of our work is to study the effect of exogenous phytohormones on the germination and growth of durum wheat (Triticum durum Desf.) under PEG-induced drought stress.

Methods: Exogenous Gibberellic Acid (GA3), Salicylic Acid (SA) and Auxin (IAA), were applied by priming technique. Seven treatments were used as follow; Control, GA3 (0,1mM), GA3 (0,25mM), SA (0,1mM), SA (0,25mM), IAA (0,1mM) and IAA (0,25mM), to investigate  the effect of priming on seed germination rate, germination precocity, electrolyte leakage, relative water content and proline.

Results: Results show that exogenous plant hormones improve germination parameters of (T. durum) under PEG stress. Exogenous GA3, SA and IAA positively enhanced the growth profile of seedlings by improving proline and relative water content and decreasing electrolyte leakage under drought.

Conclusion: The performance of primed seed with plant hormones was found better than control under PEG-induced drought, and more investigations are required to explore the possible effects of these phytohormones on plants growth and productivity under drought stress.
