Gibberellic acid treatment of steeped barley increased the activity of α‐amylase and the amount of inorganic phosphate but had no significant effect on the amounts of total phosphate, acid‐soluble bound phosphate, lipid phosphate, residual phosphate, ribonucleic acid (determined as nucleotides) and deoxyribonucleic acid (determined by diphenylamine reaction). Although gibberellic acid appeared to increase the 6‐amino: 6‐oxo ratio of ribonucleic acid in the early stages of germination, the differences in the nucleotide composition of ribonucleic acid between control and gibberellic acid treated seeds were not significant. It is suggested that, in response to gibberellic acid treatment, messenger ribonucleic acid specific for certain enzymes may be synthesized, thus leading to the increased synthesis of specific enzyme proteins.
