Effect of 1-methylcyclopropene (1- MCP) treatment on antioxidant enzymes of postharvest Japanese apricot

Abstract

‘Longyan Mei’, a Japanese apricot species, was used to investigate the effect of 1-methylcyclopropene treatment on the browning index, soluble solid content (SSC), titratable acidity (TA) and enzyme activity of active oxygen-related metabolism of post-harvest Japanese apricot. The results show that 1-MCP inhibited the browning rate, maintained a high content of SSC and TA, controlled the increase of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) activity at prophase of storage, and increased the enzyme activities of SOD, POD and CAT at the end of the storage.

Keywords: Japanese apricot, 1-MCP, superoxide dismutase (SOD), peroxidase (POD), catalase (CAT)
