Abstract
The aim of the present investigation was to determine the effect of exogenously application of salicylic acid (SA) in plants. Salicylic acid (SA) act as a potential non-enzymative antioxidant as much as plant growth regulator, playing an important role in regulating a number of plant physiological processes. SA has been identified as a signaling component in numerous plant responses to stress, including UV-B, exposure to ozone and pathogen attack. SA is also involved in activation of the stress induced antioxidant system stimulates flowering in many plants, increase flower life, control ion uptake by roots and stomatal conductivity.
