Caffeic acid (CA) is known as an antioxidant to scavenge reactive oxygen species (ROS), but the underlying mechanism of mediation plant salt tolerance against various abiotic stresses by caffeic only partially understood. A field experiment (120 days duration) was conducted investigate protective role under a high saline medium (EC 8.7 dS m -1 and textural class: sandy loam) in two wheat genotypes (FSD -08 Zincol-16). Two levels (50 μM 100 μM) were applied exogenously combination with salinity stress results revealed that alleviation more prominent when at rate μM. Under conditions, show poor fresh dry matter accumulation, chlorophyll contents, relative water contents (RWC), membrane stability index (MSI) activities enzymes increased uptake Na + ions. However, genotype FSD-08 eminently responded application compared Zincol-16 demonstrated higher growth indicators, RWC, MSI, enzymes, accumulation mineral ions grain along yield attributes. In addition, also mitigated salt-induced oxidative malondialdehyde (MDA) hydrogen peroxide (H 2 O ) well significantly reduced uptake. It can be concluded acid-induced attributed improved relations, K uptake, enzymes.
