Abstract

The review reveals convincing evidence that ethylene is involved in the acceleration of abscission.
Whether it is an absolute requirement for the induction of the process is more controversial.
Auxins can be shown experimentally to be very effective inhibitors although there is little unequivocal evidence that auxin concentration regulates natural abscission.
A modified auxin ethylene balance model of regulation seems to fit the experimental facts best.
This envisages that the progress of abscission is determined by the inhibiting influence of auxin concentration counterbalanced by the accelerating effects of ethylene.
The effectiveness of both these hormones is subject to modulation by factors such as receptor concentration, which influence the sensitivity of the tissue
