Abstract
Two years of morphological observations showed that flower bud differentiation of longan did not occur until shoots elongated.
The morphogenesis of apical and axillary meristems proceeded independently with leaves in some inflorescence.
Axillary inflorescence developed when leaflets were removed and the terminal bud stopped growing.
Ethephon increased cytokinin (CTK) and abscisic acid (ABA) and decreased gibberellin (GA) concentrations.
Cytokinin and ABA concentrations promoted flower bud morphogenesis while GA inhibited it.
