Combretum nigricans is a species of high socio-economic importance in West Africa and particularly in Burkina Faso. However, the strong anthropic pressure and the lack of knowledge on the different modes of regeneration constitute the main factors which hinder the stability of the stands of the species. The objective of this study was to evaluate the ability of C. nigricans for vegetative propagation. To do this, two modes of vegetative regeneration were tested, namely root and stem cuttings and air layering. The results show that C. nigricans does not respond to vegetative propagation by root cuttings. However, tests on aerial fragment cuttings show that time period has a highly significant effect (p< 0.001) on the ability of the cuttings to vegetatively recover. The survival of the cuttings is strongly influenced by the diameter of the fragments (p< 0.001) and also varies from one period to another. Air layering carried out in March (during vegetative rest) gave after 06 months of follow-up a success rate of 45% with a high success rate for branches 16 to 18 mm in diameter. These preliminary results show that it is possible to reproduce C. nigricans by stem cuttings and air layering. These results are promising and open interesting perspectives for the improvement of gum production in Burkina Faso.

Abstract: (french)
Combretum nigricans Lepr. ex Guill. & Perr. est une espèce à haute importance socio-économique en Afrique de l’Ouest et particulièrement au Burkina Faso. Cependant, la forte pression anthropique et l’insuffisance de connaissances sur les différents modes de régénération constituent les principaux facteurs qui entravent la stabilité des peuplements de l’espèce. L’objectif de cette étude était d’évaluer l’aptitude de C. nigricans à la multiplication par voie végétative. Pour ce faire, deux modes de régénérations par voie végétatives ont été testés à savoir le bouturage racinaire et caulinaire et le marcottage aérien. Les résultats montrent que C. nigricans ne répond pas à la multiplication végétative par bouture de racine. Cependant, les essais sur les boutures de fragment aérien montrent que la période a un effet très significatif (p< 0,001) sur la capacité de reprise végétative des boutures. La survie des boutures est fortement influencée par le diamètre des fragments (p< 0,001) et varie également d’une période à une autre. Le marcottage aérien réalisé en mars (pendant le repos végétatif) a donné au bout de 06 mois de suivi un taux de réussite de 45% avec un fort taux de succès pour les branches de 16 à 18 mm de diamètre. Ces résultats préliminaires montrent qu’il est possible de reproduire C. nigricans par bouturage de tige et par marcottage aérien. Ces résultats sont prometteurs et ouvrent des perspectives intéressantes pour l’amélioration de la production en gomme au Burkina Faso.
