Abstract
Tubers cv. Monalisa were analysed to determine the content of abscisic acid (c-t-(+)ABA) and related metabolites in three tuber parts (eyes, sub-eye tissues and pith). Analyses were performed from the last period of tuber growth until sprouting under two different storage temperatures (3 °C and 23 °C). ABA content rises in eyes and sub-eye tissues as sprouting approaches, regardless of storage temperature. Dihydrophaseic acid is the main ABA metabolite while phaseic acid was not detected, probably because of its further metabolization to DPA. ABA-glucose ester concentrations are generally low in all tissues except in eyes before harvest. The results are discussed in relation to the current hypotheses on the role of ABA in the control of potato tuber dormancy.
