Mitigating effect of salicylic acid in the anatomy of the leaf of Zea mays L. lluteño ecotype from the Lluta Valley (Arica-Chile) under NaCl

It is known that exogenous salicylic acid (SA) plays a role in the response of plants to salt and osmotic stresses. In recent years, SA has been shown to increase the concentrations of organic solutes for osmoregulation in plants subjected to salt stress. Therefore an experiment was conducted to inv...

description It is known that exogenous salicylic acid (SA) plays a role in the response of plants to salt and osmotic stresses. In recent years, SA has been shown to increase the concentrations of organic solutes for osmoregulation in plants subjected to salt stress. Therefore an experiment was conducted to investigate the impact of exogenous SA on the tissue morphology of lluteño maize. The treatment consisted of salt and SA (0.1 mM). Salt stress negatively affected leaf anatomy by showed a positive effect of SA on the composition of structures such as xylem vessels, Kranz anatomy, mesophyll cells, epidermal tissues, leaf blades and chloroplast development. It also increased the number of stomata per unit area. Finally, the presence of salicylic acid in saline conditions has beneficial effects on the morphology of lluteño maize, likely contributing to the tolerance to salinity.
