dc.descriptionIt has been shown that abscisic acid (ABA) and salicylic acid (SA) act as endogenous signal molecules responsible for inducing abiotic stress tolerance in plants. However, our knowledge on the role of both phytohormones in response to environmental conditions in halophytic plants is still limited. In this study endogenous ABA and SA levels, growth parameters and chlorophylls content were determined in leaves and roots of the halophyte Prosopis strombulifera cultivated under increasing NaCl and Na2SO4 concentrations, at 30 and 70 % relative humidity (RH) conditions. Endogenous ABA and SA content differed depending on the salt type and concentration, RH, plant age and the organ analyzed. Under low RH conditions P. strombulifera growth was strongly inhibited and chlorophyll a and b content were decreased. In leaves of Na2SO4-treated plants at 30 % RH, high ABA levels were correlated with protection against dehydration and ion toxicity. Instead, high SA levels were correlated with the damaging effect of sulfate anion and low RH on plant growth. NaCl-treated plants growth was also inhibited at 30 % RH although levels of both hormones were not significantly increased. Taken together, the salt toxic effects on growth parameters and photosynthetic pigments were accentuated by low RH conditions and these responses were reflected on ABA and SA content.
