Abstract
Young immature bitter melons were fumigated with 1-MCP at different concentrations (0.5, 5.0 or 50.0μll−1) for 12h, then stored at 20°C and 85–90% relative humidity (RH) to investigate postharvest quality and physiology. According to the visual appearance of bitter melon, we determined the effective concentration of 1-MCP was 5.0μll−1. Furthermore, we demonstrated that the application of 1-MCP inhibited ethylene production and thereby improved fruit quality of bitter melon as reflected from ascorbic acid (AsA) and soluble protein content. In addition, 1-MCP maintained antioxidant enzymes activities such as superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) of bitter melon at initial stage but suppressed at the subsequent shelf life. Our results suggested that the use of 1-MCP was an effective method to retain postharvest physiology and quality of bitter melon.
