Purpose: In this study, the effects of different concentrations of salicylic acid on the physiological traits of Alstroemeria (Alstroemeria hybrida cv.ʻSummer Skyʼ) cut flowers during pre-harvest and postharvest applications are investigated. The aim of this study was to identify the best treatments and methods affecting the vase life of cut Alstroemeria flowers. Research Method: The study was performed as a factorial experiment based on a completely randomized design using three replications in each combination/mixed treatment. The factors comprised of the pre-harvest foliar and post-harvest (pulsing 24h and continuous) applications of salicylic acid at two concentrations of 30, 200 ppm (SA1) and 50, 300 ppm (SA2), respectively. Findings: The vase life, chlorophylls a, b, and total, relative fresh weight, SOD activity, and the percentages of dry matter and the absorption of preservative solution were evaluated. The results showed that using high concentrations of salicylic acid (SA2) significantly increased the vase life of Alstroemeria. The pre-harvest foliar application of a 300 ppm of salicylic acid would be useful in prolonging the vase life of cut Alstroemeriaflowers and thus would help to reduce the losses caused by the rapid senescence of petals which will lead to an increase in the quality of appearance and economic value. Research limitations: There was no significant limitation to be reported. Originality/Value: The positive impact of salicylic acid (50 ppm) in the pre-harvest method (B) was found, and its application improved the vase life of cut Alstroemeria flowers, which should be taken into consideration for commercial uses.
