The jujube tree (Ziziphus mauritiana Lam., Rhamnaceae family) is an exotic species which is commonly found in the Sahelian and Sudanian areas of Africa. A programme was undertaken in Senegal to introduce domesticated varieties and adapt them to the edaphic and climatic specificities of the Sahel. Research focussed on the 'Gola' variety, multiplied by an in vitro micrografting technique which is a miniaturisation of the apex splice, involving the aseptic grafting of miniature scions (5 to 10 mm long) onto the hypocotyl of seedlings in vitro. Studies reported here include the choice and preparation of rootstock, the micrografting technique, acclimation of the grafts, and transplantation to the field. The outcome of this research is the achievement of successful establishment of over 80% of the micrografts. However, more work is required to evaluate the transferability of the techniques through a study of their economic viability, as well as their acceptability to local people.
