Argumentaire pour l’étude et l’utilisation des marcottes et drageons dans les pays à faible couvert ligneux

Seed sowing, planting or vegetative propagation after felling are used to reconstitute the vegetation cover. Sometimes, the first two methods end up being ineffective and costly. Terrestrial layering and suckering provide an interesting alternative in some areas. In semiarid regions mainly, it is necessary to have a better knowledge of the vegetative propagation process. To that end, launching specific case studies on key species from these areas should be initiated.
