Activation of abscission zone located between pedicel and fruit (AZ3) is preceded by a reduction of the tissue transport capacity, a block of IAA conjugation and an increase of IAA decarboxylation (Ramina et al., 1984). Since peroxidases and IAA oxidases are known to play a role in IAA metabolism, changes in activity of these enzymes as related to the induction phase of abscission were investigated.

Abstract
Activation of abscission zone located between pedicel and fruit (AZ3) is preceded by a reduction of the tissue transport capacity, a block of IAA conjugation and an increase of IAA decarboxylation (Ramina et al., 1984). Since peroxidases and IAA oxidases are known to play a role in IAA metabolism, changes in activity of these enzymes as related to the induction phase of abscission were investigated.
