We examined the role of cytokinins (CKs) in release of apical dominance in lateral buds of chickpea (Cicer arietinum L.). Shoot decapitation or application of CKs (benzyladenine, zeatin or dihydrozeatin) stimulated rapid bud growth. Time-lapse video recording revealed growth initiation within 2 h of application of 200 pmol benzyladenine or within 3 h of decapitation. Endogenous CK content in buds changed little in the ®rst 2 h after shoot decapitation, but signi®cantly increased by 6 h, somewhat later than the initiation of bud growth. The main elevated CK was zeatin riboside, whose content per bud increased 7-fold by 6 h and 25-fold by 24 h. Lesser changes were found in amounts of zeatin and isopentenyl adenine CKs. We have yet to distinguish whether these CKs are imported from the roots via the xylem stream or are synthesised in situ in the buds, but CKs may be part of an endogenous signal involved in lateral bud growth stimulation following shoot decapitation. To our knowledge, this is the ®rst detailed report of CK levels in buds themselves during release of apical dominance.Abbreviations: BA = N 6 -benzyladenine; CK = cytokinin; cv = cultivar; DHZ = dihydrozeatin; IP = isopentenyl adenine; IPA = isopentenyl adenosine; Z = zeatin; ZR = zeatin riboside
