Development of agrientrepreneurship in Samoa: opportunities and challenges

Plukenetia conophora, an economic plant, is sourced mainly in the wild. In order to promote its rapid and mass propagation, a tissue culture technique was developed. The embryos excised were cultured on MS medium supplemented with naphthalene acetic acid (NAA), benzyl amino purine (BAP) and Kinetine (KIN) at different concentrations. The best combination for the embryo culture was on MS supplemented with 0.3mg KIN and 0.01mg NAA with a shoot length of 3.10 cm, and number of node of 3. The longest root length of 5.50±0.24 was obtained on 0.3mg KIN and 0.05mg NAA. The best result of nodal culture was achieved on MS supplemented with 0.30mg BAP and 0.05 mg NAA with a mean shoot length of 2.13±0.05, root length of 2.00±0.00 and number of node of 2.00±0.00. The growth of Plukenetia conophora was successful in vitro and this will enhance its mass propagation.
