Notes:
Abstract Levels of endogenous ABA and IAA were quantified during the first week of in vitro rooting of Wild Cherry (Prunus avium L.) using IBA in the culture medium. Hormones were measured in the apical, median and basal parts of the explants using an avidin-biotin based enzyme linked immunosorbent assay (ELISA), after a purification of the methanolic extracts by high-performance liquid chromatography (HPLC). Root primordia started to differentiate from day 5 at the basal part of the explants. ABA and IAA showed considerable changes and high levels were detected during the first week of culture. ABA levels increased transiently mainly in the apical part during root formation. Exogenous IBA was possibly transformed into IAA mainly in the basal part of the explants.
