摘要

Four-week-old seedling explants of Bambusa arundinacea were cultured on Murashige and Skoog (MS) basal medium with different cytokinins to study the effect on in vitro induction of flowering, The cytokinins used were adenine hemisulphate (AdS), 6-[gamma,gamma-dimethylallylamino]-purine (2iP), kinetin (Kin), zeatin individually and in combination with 6-benzyl adenine (BA), BA was found to be the only cytokinin inducing flowering in vitro when added individually in the culture medium. The induction of flowering ill media containing other cytokinins, when added individually, was not observed, However, induction of flowering was observed in all the cytokinin combinations whenever BA was added, Presence of BA in the culture medium was observed to be absolutely essential for induction of flowering. 2iP showed synergistic effect in combination with BA although it was ineffective in the presence of flower induction alone, while zeatin showed antagonistic effect on induction of flowering in combination with BA.
