Impact of 1-MCP/ethrel treatment on PbrPG6 expression, PG activity and cortex firmness of pear. a Expression profile of PbrPG6 after 1-MCP and ethrel treatments. b Impact of 1-MCP and ethrel treatments on PG activity. c Impact of 1-MCP and ethrel treatments on cortex firmness. ‘Housui’ pears, harvested from an experimental orchard in Nanjing, were divided into three treatments: (1) fumigated with 1.5 μL L− 1 1-MCP for 24 h, (2) dipped in 0.5 mL L− 1 ethrel for 5 min, and (3) dipped in 0.5 mL L− 1 H2O for 5 min (control). After treatments, fruits were packed with plastic bags and stored at 25 °C for 5 d. Data represent the mean ± SE of three biological replicates. The expression level of PbrPG6 in control fruit was set as 1.0. Vertical bars labeled with different small letters indicated significant difference between samples at p < 0.05 level using Duncan’s multiple range test
