Conference paper

Ethylene and auxin (IAA) are important regulators of abscission. IAA retards, whilst ethylene is a potent accelerator of the process. The general rule portrays that provided the flux of IAA to the abscission zone region is maintained; the cell separation is inhibited and abscission does not occur (Addicott, 1982; Brown, 1997).
