Project description:Onion is regarded as non-climacteric. In onion, ethylene can suppress sprouting however, the ethylene binding inhibitor, 1-MCP can also suppress sprout growth although it is unknown how ethylene and 1-MCP elicit the same response. In this study, onion bulbs were treated with 10 μL L-1 ethylene or 1 μL L-1 1-MCP individually or in combination for 24 h at 20°C before or after curing (six weeks) at 20 or 28°C then stored at 1°C. Following curing, a subset of these same onion bulbs was stored separately under continuous air or ethylene (10 μL L-1) at 1°C
