The results showed that 1-MCP and its structural analogues could inhibit the respiration intensity and ethylene production rate, decrease the loss of fruit firmness, delay the reduction speed of acidity and inhibit the activities of cellulase and polygalacturonase related to fruit softening. Moreover, no significant difference was found between 1-MCP and its structural analogues.
