Cut roses are characterized as highly perishable products due to the intense metabolism during postharvest, mainly the rise in respiratory activity and fast senescence. This study evaluated the effects of applications of 0.05 mM methyl salicylate (MeSA), 1.0 mM of salicylic acid (SA) and 1.0 µL L-1 of 1-methylcyclopropene (1-MCP) in maintaining the quality postharvest of cut roses cv. Vega. After treatments for 12 h, roses were kept at 20±1°C and 65±5% RH in vases with deionized water. The flowers were evaluated every two days for ten days concerning respiratory activity, ethylene production, peroxidase (POD) activity, relative fresh weight (RFW), relative water content (RWC) of the and floral opening . The results show that SA and 1-MCP reduced the respiratory activity and ethylene production, increase POD activity, RFW and the RWC of the petals. However, the 1-MCP is the only that improves the floral opening.
