Adenia goetzei is a plant with a decorative prominent caudex. An efficient micropropagation system based on axillary shoot formation and subsequent rooting was developed. By alternating culture on a medium with 5µM BAP (a modified Murashige & Skoog (1962) medium) and a medium without BAP (Krogstrup et al., 1988), a multiplication factor of 3.93 /- 1.16 (mean /- SD) was achieved every 6 weeks. Approximately 61 % of the micro-cuttings rooted following a 24 day 5µM IBA treatment and 80–85% of the plants were successfully transplanted to soil. The juvenile twining growth- and leaf form reverted to a form with adult characteristics after 1–2 growth periods in soil. Using this micropropagation protocol for A. goetzei, it has been possible to produce several hundred vigorous and true-to-type plants, except for irregularly shaped caudices in contrast to the regular ones seen in seedlings.
