Effects of 1-methylcyclopropene (1-MCP), salicylic acid (SA), and 1-MCP and SA combined treatments on SOD (A), POD (B), CAT (C), APX (D), GR (E), and PAL (F) activities of winter jujube during shelf life at 4 ± 1°C for 20 d. SOD, superoxide dismutase; POD, polyphenol oxidase; CAT, catalase; APX, ascorbic acid peroxidase; GR, glutathione reductase; PAL, phenylalanine ammonia-lyase. The data presented are the mean values of three replicates; vertical bars represent the standard errors of the mean values; values followed by different superscripts (a-d) are significantly different (P < 0.05) on the same sampling date.
