In Vitro Propagation of Garcinia livingstonei T. Anderson (African Mangosteen) a Woody Tree Species through the Culture of Matured Seed Segments

Abstract

The in vitro propagation and ex situ conservation strategy provides new means for the conservation and mass propagation of economically and medicinally important plants. The present work aimed to observe the main characteristics of the in vitro propagation of Garcinia livingstonei from matured seed segments. Successful multiple shoots were induced on a woody plant (WP) medium supplemented with cytokinins. An average of 13.0 shoots per explant were grown from matured seed segments on a WP medium containing 15.0 µM BAP after 12 weeks of culture. The shoot elongation and multiplication were achieved using a repeated and periodic subculturing of shoot clumps in the same medium. The optimum in vitro rooting of shoots was obtained on the half-strength WP medium supplemented with IBA (5.0 µM). The regenerated plantlets were successfully transplanted to pots containing soil, sand, and farmyard manure (1:1:1) and were maintained in a greenhouse with a survival frequency was 80%.
