Abstract
The effect of gibberellic acid on the secretion of proteins from barley (Hordeum vulgare L.) aleurone layers has been investigated for its suitability as a gibberellin bioassay. Concentrations from 10−4 μg/ml to 100 μg/ml of GA3 resulted in the release of proportionally increasing amounts of total protein. The release of proteins is not affected by indoleacetic acid and kinetin. This method has been applied and compared with the α-amylase assay for the estimation of gibberellin in extracts of tomato fruits and maize seedlings.
