Griffonia simplicifolia is a Caesalpiniaceae legume that grows from Liberia to the Democratic Republic of the Congo. These leaves are widely used in Togo for their nutritional value. Griffonia simplicifolia on the other hand is most known for its 5-HTP seeds. Farmers collect significant amounts of fodder directly from Togo's forest formations, resulting in a scarcity of this species, which is classed as non-timber forest products (LNFP). Massive anthropization, in combination with the low germinative potential of Griffonia simplicifolia seeds, poses a threat to the species' survival and availability. It is critical to promote and disseminate Griffonia simplicifolia 's culture in order to help save the species, which is presently critically endangered. It is in this perspective that the study of germination and conservation of the germination capacity of Griffonia simplicifolia seeds is conducted. The ecotype being studied is that of Lome, which was harvested on campus. Light, integuments, time, and storage temperature were all factors considered when studying germination. To optimize the germination speed, it is essential to remove the seed coat and germinate the seeds with light in the greenhouse as in vitro . The cold helps to preserve the germination capacity of seeds, which deteriorates quickly in warm environments.
