In order to extend the shelf life of banana cultivar Grand Naine was fumigated with 1-methylcyclopropane (1-MCP) at four different concentrations (100, 200, 300 and 400 ppb) @ 24h exposed time and stored at ambient conditions. Among all the treatments, 400 ppb was found to be an effective in extending shelf-life, highest retention of cell wall degrading enzyme such as Pectin methylestarase and free radical scavenging enzymes peroxidise and catalase. The entire 1-MCP treated banana showed better results over control (kept at open air @ 24h). | Postharvest fumigation of 1-MCP influences cell wall degrading and antioxidant enzymes in banana Musa paradisiaca L.
