<abstract xmlns="http://www.w3.org/1999/xhtml">An efficient and reproducible micropropagation protocol of <italic>Solanecio biafrae</italic> (Oliv. &amp; Hiern) C.

Elongated shoots were rooted in the presence of zeatin or 3-indole-butyric acid (IBA) alone or in combinations. The highest number of explants forming shoots (100%) as well as the highest number of shoots per explant (3.4) and the longest shoots (22 mm) were recorded on medium containing 4.0 mg·dm−3 BAP, 2.0 mg·dm−3 NAA, and 1.0 mg·dm−3 zeatin.
