Abstract
Tissue cultures were established from hypocotyl and cotyledonary leaf segments ofGuizotia abyssinica Cass. on MS medium supplemented with various concentrations of auxins (IAA, NAA, IBA or 2,4-D) and cytokinins (KN or BA). Expiants cultured on media with cytokinins or in combination with auxins produced shoot buds. Maximum number of shoot buds (20-25 per culture) were differentiated from cotyledonary leaf segments on medium with 2 mg 1-1 each of KN and IBA. Rooting of regenerated shoot buds was acheived on medium with NAA. The obtained plantlets were successfully transferred to soil.
