Free abscisic acid accumulates in both the skin and pulp together when the seeds begin to change colour. It obtains its maximum (at the half veraison) earlier than bound abscisic acid (at the end of the veraison). Then, abscisic acid is progressively catabolised and the level of bound abscisic acid (storage form) remains above than of free abscisic acid.
