- •
Abscission of Dendrobium flowers stored at 5–15° took place after transfer to 25 °C.
- •
Abscission was greater at 5 °C than at 15 °C after transfer to 25 °C.
- •
1-MCP inhibited abscission and the activity of several cell wall hydrolases in the AZ.
- •
1-MCP inhibited the expression of several genes encoding cell wall hydrolases.
