In the present study, 1-MCP at a concentration of 1 mL Ll
effectively suppressed ethylene production and respiration rate.
The quality parameters including firmness, SSC, TA and vitamin C in
1-MCP-treated fruit kept at a much higher level than those in
untreated fruit stored at both 25 and 0 C. Additionally, 1-MCP
increased the resistance of jujube fruit against P. expansum. The
delayed senescence and induced resistance by 1-MCP may be
related to the enzyme activity of CAT and SOD, which are associated
with ROS scavenging, and PAL and PPO, which are involved in
phenolics metabolism. Our results suggest that 1-MCP can provide
a feasible technique for maintaining the quality and extending
storage life of jujube fruit.
