Abstract
ABSCISIC acid (ABA) is the only plant growth substance so far reported1,2 to inhibit gibberellin(GA)-induced amylolyis in barley half seeds or α-amylase production in barley aleurone layers: the former physiological response has been used as a bioassay for ABA3,4. But the isolation procedures normally used to extract ABA from plant tissue also extract certain short-chain fatty acids5. We now present evidence that these naturally occurring short-chain acids5 are powerful inhibitors of GA-induced amylolysis in barley endosperm.
