Effects of ABA, ethylene, and inhibitors on pepper fruit ripening. Twenty one LG fruits attached to plants were used for treatment (n = 7, three replications) and water was used as a control. The treated and control fruits were placed in a growth chamber for 8 days. Three treated fruits were used to determine ethylene emission levels. (a) Fruits were treated with 50 μM ABA, 100 μM fluridone, 50 μM ethephon, or 1 mL/L 1-MCP. (b) Ethylene emission in the ABA-, fluridone-, ethylene-, and 1-MCP-treated fruits. Error bars represent the SE (n = 3). An asterisk (*) in columns of the same colour indicates a statistically significant difference (P < 0.05) based on analysis of variance followed by Duncan’s multiple-range test
