SUMMARY Eye plugs removed from tubers of four potato cultivars previously stored for 14 days at 2 °C and then left at 15 °C for a further 14 days contained more gibberellin and less growth inhibitor activity than those kept at 15 °C for 28 days. Two gibberellin‐active peaks were obtained when the extracts from cold‐treated tubers were separated on paper chromatograms with an isopropanol/ammonia/water solvent. The main inhibitor did not appear to be abscisic acid.
