Gibberellic Acid: Action in Barley Endosperm Does Not Require Endogenous Auxin

Abstract
Endogenous auxin is not required for the increase in amylolytic activtiy induced by gibberellic acid in barley endosperm, as shown by the response of the system to anti-auxin. The action of gibberellic acid in this system is independent of the presence or absence of auxin.
