Abstract
Mahogany (Swietenia macrophylla King.) is a tree species that has considerable potential for the development of plantation forests. However, mahogany plant propagation is generally done generatively, namely by seed. Mahogany seeds are intermediates that have a low shelf life and take 9-12 months from flowering to ripe fruit. The efforts that can be made are through vegetative means, with tissue culture. The success of tissue culture is strongly influenced by the growth medium, which is one of the main factors in plant propagation and has a major influence on the growth and development of explants and seeds produced. The purpose of this study was to obtain the best-growing media for optimizing the growth of mahogany explants in vitro. The research method used was a Completely Randomized Design (RAL) with 1 factor, namely the type of medium with three replications. Variables, namely the time of leaf emergence, the timing of the shoot^s emergence, the number of shoots, and plant height. The results showed that MS media with the addition of adenine sulfate, 0.5 ppm BAP, and 0.2 ppm Kinetin were the best medium for the growth of mahogany (explants.
