Apical and axillary buds of Guizotia abyssinica Cass., isolated from seedlings raised in vitro, were cultured. High frequency of shoot regeneration was achieved on MS medium with BAP (1 mgl(-1)). Effect of BAP, Kn and GA3 applied successively in culture on shoot regeneration and flower bud formation has been studied. The shoots differentiated in cultures elongated on this medium. These rooted subsequently on half strength MS medium. The shoots flowered in vitro on MS medium with a combination of BAP (0.1mgl(-1)) + GA3 (0.1 mgl(-1)). The plantlets thus formed were successfully hardened with 90 % survival.
