Modulation of salt-induced stress impact in Gladiolus grandiflorus L. by exogenous application of salicylic acid

Abstract Salinity is challenging threats to the agricultural system and leading cause of crop loss. Salicylic acid (SA) is an important endogenous signal molecule, which by regulating growth and physiological processes improves the plant ability to tolerate salt stress. Considering the prime importa...
