In the last few years, increasing interest in the foliar application of salicylic acid (plant hormone) on plants has considerably expanded our knowledge concerning its effects on plants’ metabolism in stresses such as freezing, drought, disease, insect attack, and nutrient deficiencies. To investigate the effects of salicylic acid (SA) on secondary metabolites (like betanin and vulgaxanthin, total phenol content, anthocyanin, and alkaloids). in beet (Beta vulgaris L.), the plants were sprayed with 0.4, 0.8, 1.2, 1.6, 2.0, 2.4, 2.8, and 3.2mM of salicylic acid concentrations along with a control. Dark red variety of beet were used in the experiment. Based on preliminary findings and discussion, foliar application of salicylic acid may enhance betanin, vulgaxanthin, total phenol content at 0.8mM, and anthocyanin and alkaloids at 1.2mM.
