Alstroemeria is one of the most important cut flower crops globally, known for its diversity in color, various cultivars, and overall beauty, contributing to its success in the global market. The use of different preservative solutions at various stages of cut flower supply to the market plays a critical role in preventing ethylene production and maintaining the water balance and energy supply required for the plant after being separated from the mother plant. Therefore, this investigation effect of 1-methylcyclopropene (1-MCP) and methyl jasmonate (MeJA) on the post-harvest life of alstroemeria (cv. Calgary) cut flowers was conducted in the Department of Horticultural Science and Landscape Architecture, Faculty of Agriculture, Ferdowsi University of Mashhad. The experiment was done in a factorial design (3 × 3) with five repetitions for each treatment. The results of the main effect of methyl jasmonate (MeJA) application showed that the highest water uptake, relative fresh weight, vase life, chlorophyll a and b, anthocyanin, catalase, peroxidase, and superoxide dismutase were observed at a concentration of 0.2 µL/L of MeJA. The main effect of 1-MCP application showed that the highest water uptake, relative fresh weight, vase life, chlorophyll a and b, anthocyanin, catalase, peroxidase, and superoxide dismutase were observed at a concentration of 1 µL/L of 1-MCP. The results of the interaction effect between MeJA and 1-MCP application showed that the highest water uptake, relative fresh weight, vase life, chlorophyll a and b, anthocyanin, and antioxidant enzymes were observed in the treatment with 4% sucrose+300 mg l-1 8-HQS+1 µL/L 1-MCP + 0.2 µL/L MeJA.
