Medicinal plants are especially used by vulnerable populations in Burkina Faso to solve their health problems. Flemingia faginea is a medicinal plant overexploited and its wetland habitat is threatened by climate change. Thus, this study aims to promote the ex-situ reproduction of F. faginea, and make it accessible as a remedy for people suffering from blood pressure disease. The capacity of reproduction by cutting has been tested by using two types of substrates and four types of cuttings. The results showed that the composite substrate is performing better than the sterilized sand for height growth (P˂0.001), leaves production (P˂0.006) and number of branching (P˂0.001). As the types of cutting is concerned, the apical cuttings recorded better growth for two parameters than others in the nursery about the height growth in centimetre (14.44 ± 9.37a), the number of leaves (5.11 ± 3.18a) and the median cuttings recorded the greatest number of branching (2.30 ± 2.03a). For each growth parameter the results are different between the types of cuttings (P˂0.001). This survey allows the cutting reproduction of F. faginea.

“…The success of air layering/marcotting, which is used to capture the phenotype of a mature individual tree, was affected by the position, orientation and diameter of the marcotted branches and the marcotting season and rooting substrate, with orthotropic and upper branches of Cola acuminata, G. kola and D. edulis and lower pollarded stems of A. parviflora showing the best rooting [149,373,374]. On the other hand, marcotts of P. macrophylla and C. lepidota in the Nigerian savanna rooted well following an application of auxin when treated during the rainy season [375,376], while in Gabon, Santiria trimera marcots formed roots independent of the type of substrate used [377].…”

This paper follows the transition from ethnobotany to a deeper scientific understanding of the food and medicinal properties of African agroforestry tree products as inputs into the start of domestication activities. It progresses on to the integration of these indigenous trees as new crops within diversified farming systems for multiple social, economic and environmental benefits. From its advent in the 1990s, the domestication of indigenous food and non-food tree species has become a global programme with a strong African focus. This review of progress in the third decade is restricted to progress in Africa, where multi-disciplinary research on over 59 species has been reported in 759 research papers in 318 science publications by scientists from over 833 research teams in 70 countries around the world (532 in Africa). The review spans 23 research topics presenting the recent research literature for tree species of high priority across the continent, as well as that in each of the four main ecological regions: the humid zone of West and Central Africa; the Sahel and North Africa; the East African highlands and drylands; and the woody savannas of Southern Africa. The main areas of growth have been the nutritional/medicinal value of non-timber forest products; the evaluation of the state of natural resources and their importance to local people; and the characterization of useful traits. However, the testing of putative cultivars; the implementation of participatory principles; the protection of traditional knowledge and intellectual property rights; and the selection of elite trees and ideotypes remain under-researched. To the probable detriment of the upscaling and impact in tropical agriculture, there has been, at the international level, a move away from decentralized, community-based tree domestication towards a laboratory-based, centralized approach. However, the rapid uptake of research by university departments and national agricultural research centres in Africa indicates a recognition of the importance of the indigenous crops for both the livelihoods of rural communities and the revitalization and enhanced outputs from agriculture in Africa, especially in West Africa. Thus, on a continental scale, there has been an uptake of research with policy relevance for the integration of indigenous trees in agroecosystems and their importance for the attainment of the UN Sustainable Development Goals. To progress this in the fourth decade, there will need to be a dedicated Centre in Africa to test and develop cultivars of indigenous crops. Finally, this review underpins a holistic approach to mitigating climate change, as well as other big global issues such as hunger, poverty and loss of wildlife habitat by reaping the benefits, or ‘profits’, from investment in the five forms of Capital, described as ‘land maxing’. However, policy and decision makers are not yet recognizing the potential for holistic and transformational adoption of these new indigenous food crop opportunities for African agriculture. Is ‘political will’ the missing sixth capital for sustainable development?

Malgré son importance socioéconomique, la production ivoirienne de noix de cola est confrontée à plusieurs difficultés. Le manque de techniques culturales éprouvées constitue une des contraintes pour la domestication et la culture du colatier. Il est donc nécessaire de mettre au point des techniques adaptées à l’espèce cultivée. L’objectif de cette étude est d’optimiser la méthode de bouturage sous tunnel du colatier (Cola nitida), face aux inconvénients de la multiplication générative. Le dispositif expérimental utilisé est un Split-Splot avec deux facteurs : le génotype avec cinq modalités (5 génotypes) et le nombre de feuilles avec cinq (05) modalités (1, 2, 3, 4 et 5 feuilles diminuées de moitié). Nous avons le génotype en grande parcelle et le nombre de feuilles en petite parcelle. L’aptitude des génotypes au bouturage a été évaluée à six mois à travers le taux de survie et la mesure des paramètres de croissance et de développement. Le génotype L18A1D9 a montré la meilleure aptitude au bouturage avec un taux de survie de 41,7%. Les boutures avec 4 feuilles diminuées de moitié ont eu le meilleur taux de survie (41,7%), un bon enracinement des boutures vivantes (88,9%), une biomasse totale fraîche (4,2 g) et totale sèche (1,7 g) élevée. Le succès du bouturage sous tunnel du colatier est tributaire du génotype et du nombre de feuilles. Le nombre de feuilles recommandé par bouture est de quatre (4) pour le bouturage du colatier sous tunnel.Mot clés : Bouturage, nombre de feuilles, Cola nitida, génotype. Englsih Title: Influence of genotype and number of leaves on the growth in nurseries of cola cuttings (Cola nitida [Wind.] Schott and Endlicher.)Despite its socio-economic importance, kola nut production faces several challenges. Domestication and cultivation of kola requires the adoption of propagation techniques adapted to the crop species. The objective of this study is to optimize kola (Cola nitida) vegetative propagation by cutting under tunnel. The experimental design used was a split-splot with two factors: genotype with five modalities (5 genotypes,) and leave number with five (05) modalities (1, 2, 3, 4 and 5 leaves cut in half). The ability of genotype to cutting propagation was assessed by measuring growth parameters. The survival rate of the cuttings was evaluated at six months. Root growth, number of new leaves, height gain and biomass were subsequently measured. Genotype L18A1D9 has the best ability for vegetative propagation by cuttings with a survival rate of 41.7%. To optimize vegetative propagation by cuttings under tunnel, 4 leaves cut in half by cuttings must be used for acceptable success rate (41.7%), good rooting (88.9%), a high total fresh biomass (4.2 g) and total biomass (1.7g). The success of kola vegetative propagation depends of genotype and the leave number per cutting. The number of leaves per cuttings recommended per cuttings is four (4) for kola vegetative propagation.Keywords: Cuttings, number of leaves, Cola nitida, genotype.
