Abstract

Salicylic acid (SA) is an antioxidant which has been used in recent years to increase the resistance of plants against stresses. In this study, the effect of different concentrations of Salicylic acid (0. 1, 0. 7, 1. 5, 3, 6 and 9 mM) on germination, shoot and root length, anthocyanin, reduced Sugars, protein, Ascorbic acid, dehydroAscorbic acid, and Proline were investigated in pepper 5 weeks after germination. Results showed that 0. 1, 0. 7, 1. 5 and 3 mM SA increased germination and shoot and root length while 6 and 9 mM SA concentrations decreased germination percent and shoot and root length. Also, concentrations of 1. 5 and 3 mM SA decreased Ascorbic acid and dehydroAscorbic acid content while concentrations 6 and 9 mM of SA increased Ascorbic acid and dehydroAscorbic acid content in the leaf of pepper plant. In addition, concentrations of 1. 5 and 3 mM SA caused significant increase in Sugars and protein content in the treated leaf but 6 and 9 mM of concentrations SA decreased Sugars and protein content. Furthermore, research findings showed that under experimental conditions, different concentrations of SA (0. 7, 1. 5, 3, 6 and 9 mM) increased anthocyanin and Proline contents in the leaf of pepper. In general, treatment of pepper with low concentration of SA had positive effects on plant growth while higher concentrations negatively affected the growth in pepper plant.
