Des etudes ont ete menees sur la germination de huit essences agroforestieres indigenes des forets camerounaises. La scarification manuelle etait le meilleur traitement pour toutes les especes bien qu'il existait une interaction significative entre traitement et espece. Une seule espece a ete sensible a tous les traitements. L'utilisation de l'acide sulfurique n'a pas ete une alternative effective a la scarification manuelle. Especes etudiees: Ceiba pentadra, Terminalia superba, Triplochiton scleroxylon; Cordia platythryrsa, Milicia excelsa, Pycnanthus angolense, Alstonia boonei, Ricinodendron heudelotii
