ABSTRACT
Sideroxylon obtusifolium is a native species recognized by traditional communities for its versatility, as it is used to treat various diseases, in fence construction, furniture manufacturing, and tool handles. It is also used for both human and animal consumption. However, extractive use combined with environmental impacts such as habitat loss and wildfires can cause a significant reduction in this species. Therefore, the adoption of biotechnological techniques such as plant tissue culture has been recognized as a significant resource to support the preservation of species with economic and medicinal importance and endangered. Thus, this study aimed to determine an efficient protocol for the in vitro establishment of S. obtusifolium. To achieve this, the seeds were disinfected using different chemical agents (carbendazim, chlorine dioxide, and sodium hypochlorite) for varying lengths of time to establish an efficient disinfection method. Additionally, MS ½ and WPM media, with and without the addition of activated charcoal, were tested to determine the most efficient medium composition for germination. The results indicated that sodium hypochlorite at 2% for 25 minutes was effective for seed asepsis. For germination, the most suitable medium was WPM containing activated charcoal, resulting in healthy and uniform seedlings that can serve as plant material for in vitro propagation of the species.
