    In this study, the effects of salicylic acid on growth of Arthrospira platensis (Nordstedt) Gomont were investigated. For this reason, different concentrations of salicylic acid (0.5, 1, 1.5, 2 g L-1 ) were given to cultures, then changes of optical density, chlorophyll-a and total phenolic contents were assessed. OD and methanol extract of chlorophyll-a and phenolic contents were measured by spectrophotometrically. All parameters decreased with increasing salicylic acid concentrations and LC50 value was 1.5 mg L-1 for ninth day. Growth of A. platensis declined with salicylic acid treatment.
