A completely randomized design related study was conducted to evaluate the efficacy of salicylic acid (0 as control, 100, 200 and 300 ppm) to extend flower display life with 5 most important cut flowers across the world Alstroemeria peruviana, Gerbera jamesonii, Lilium asiaticum, Rosa hybrida and Polianthes tuberose with 3 replications and 3 samples for each replication. Applying salicylic acid extended the vase life of cut flowers significantly except in Rosa Hybrida. The highest vase life was observed for the treatments of 300 ppm. The addition of 300 ppm salicylic acid to clean distilled water extended the vase life of Alstroemeria peruviana, Gerbera jamesonii, Lilium asiaticum, Polianthes tuberose and Rosa hybrida by 30 -55 (%) relative to control. Salicylic acid treatments increased relative water content, petal water content and initial fresh weight in cut flowers, over control. The beneficial effects of salicylic acid are associated with the plant regulating and anti-stress properties of salicylic acid. Results of this experiment provide support for wider testing and use of this natural, cheap, safe and biodegradable compound, as a vase solution additive for extending the postharvest longevity of cut flower species susceptible to vascular blockage of bacteria and ethylene which are used widely in the world.
