Incorporation of organic growth additives to enhance in vitro propagation of selected shrub/tree species for large scale restoration and for supporting local communities dependent on agrosilvopastoral systems in building resilience.

Climate change and anthropogenic activities have negatively impacted agro-silvo-pastoral ecosystems across the planet. The global agenda to achieve ecosystem restoration targets has resulted in an increased demand for plant materials that current production systems are unable to satisfy. Under open field cultivation, several species show a low rate of seed germination or need special climatic conditions to germinate or take a long time to establish. Consequently, there is an urgency to preserve and propagate selected genotypes by improving efficient mass propagation techniques. It is necessary to resort to innovation tools, such as in vitro tissue culture technology. Plant tissue culture is used for producing high-quality, disease-free, and true-to-type plants at a fast rate. In vitro propagation can help meet the increasing demand for planting materials aimed at large scale restoration and afforestation programs. Incorporating organic growth additives can stimulate tissue growth and increase the number of shoots, leaves, and roots.
