Abstract

Salinity stress as a major environmental factor negatively impacts plant produc-tivity. A wide range of adaptation strategies is required to overcome this stress. An alternative strategy could be exogenous application of plant growth regula-tors. The present study was carried out to study the effect of seed pretreatment with salicylic acid on some growth parameters, volatile compounds and antioxi-dant activity of salt-stressed two genotypes of okra plant. The results of this study showed that the salicylic acid is a valuable biological plant growth regula-tor that could enhance salt tolerance in okra plant under 50, 100, 150, and 200 mM NaCl levels resulting in an increase in plant growth and antioxidant en-zymes activities, when compared with the NaCl-treated control groups. There-fore, salicylic acid is a promising tool to improve plant growth and quality under harsh environmental conditions.
