Abstract

Introduction. Sclerocarya birrea (A. Rich.) Hochst. is a common species in the dry zones of Africa. Although appreciated by the populations for its fruit, the subspecies birrea, present in Western Africa, remains not domesticated and under-utilized; the subspecies caffra, originating in Southern Africa, was recently domesticated there where it occupies a considerable economic role. Within the framework of a domestication programme led in Senegal, tests studied the development of the grafting applied to S. birrea subsp. birrea. Materials and methods. Scions taken from female mature trees were grafted on young rootstock plants at five periods during the year and according to three grafting techniques (tongue grafting, top grafting and side plate grafting). Results and discussion. The most favorable period for the grafting is at the end of the rain season; no significant difference was observed between the three types of grafting technique tested. Conclusions. The propagation technique highlighted could be developed for the ex situ conservation of the genetic diversity of Sclerocarya birrea subsp. birrea and also for the selection of varieties interesting for the criteria considered (yield and fruit quality, and rusticity). In time, S. birrea subsp. birrea could constitute in Western Africa a fruit tree crop for diversification.
