The aim of the present work was to establish appropriate conditions for the in vitro micropropagation of Eremanthus erythropappus (DC.) MacLeish through shoot multiplication on apical and nodal bud explants. Explants were excised from in vitro-grown seedlings and incubated on Murashige and Skoog medium containing different combinations of 6-benzylaminopurine (BAP) and 1-naphthalene acetic acid (NAA) (for apical buds) and gibberellic acid and NAA (for nodal segments). Proliferation of apical shoots was successfully achieved in the presence of BAP and NAA, each at 1.0 mg L(-1), while the elongation of apical shoots could only be attained on medium containing NAA at 1.0 mg L(-1). Elongation of nodal shoots was induced in the presence of NAA at 2.0 mg L(-1). The most suitable medium for inducing root proliferation on explants of E. erythropappus was NAA at 1.0 mg L(-1).
