Abstract:The plant-based traditional knowledge of many Cameroonian populations concerning beauty and skin care is still poorly documented, yet they are real resources of innovation and economic development. The aim of this study is to document the indigenous knowledge of Choa Arab and Kotoko ethnic group in Kousséri (Far North Region of Cameroon) about plants used for cosmetics. Ethnobotanical data collected among key informants revealed a total of 13 plants species belonging to 12 families used by local people. Canarium schweinfurthii Engl and Santalum album L. obtained the highest frequency of citation. Trees are the most abundant life forms, while barks and seeds are the most frequently used parts. More than 40% of recorded plants are used for skin care. The cosmetic allegations of recorded plants include: dermatology, anti-cancers, antioxidant agent, perfume, anti-inflammatory, antimicrobial, wounds healing activity, skin lightening, dental caries, astringent and hair care. They all contain various phytochemicals that are of interest in cosmetics. Despite the strong relationship between the Choa Arab and Kotoko people and herbal cosmetic ingredients, these plants are still less investigated for their cosmetic application. The authors urge for the development of sustainable supply chain for plants with potentials as cosmetics, involving local communities in the planning, implementation and monitoring process, following principles of Nagoya protocol on Access and Benefit Sharing.

“…Yet, farmers attempted regeneration of V. doniana but faced constraints related to seed dormancy and long growing period, which resulted overall in very poor results (Thies, 1995;Sanoussi et al, 2012). Other methods of regeneration must be explored in order to propose appropriate solutions for the conservation of the tree species, highly demanded by local populations, and to allow its reintroduction into farmers' production systems (Mapongmetsem et al, 2012a;Meunier et al, 2006). Despite the importance of the species in Africa, little scientific research has been devoted to its regeneration, except for studies related to stem cuttings carried by Mapongmetsem et al (2012b) and Sanoussi et al (2012) which revealed a regeneration rate of 40-50.7% attributed to samples origin and environmental conditions among other factors.…”

B o i s e t f o r ê t s d e s t r o p i q u e s , 2 0 1 6 , n° 3 2 7 ( PROPAGATION VÉGÉTATIVE DE VITEX DONIANA SWEET À PARTIR DE SECTIONS DE RACINEVitex doniana Sweet est une espèce à usages multiples d'une grande importance socio-économique et commune en Afrique tropicale. Malgré sa forte utilisation en milieu rural, elle est encore présente à l'état sauvage. Il existe peu de données sur sa domestication. La propagation de cet arbre par bouturage de segments de racine constitue une alternative à sa difficile régénéra-tion sexuée. L'objectif de notre travail était d'évaluer deux des facteurs clés (substrat d'enracinement, diamètre des boutures) qui influencent l'aptitude des boutures de segments de racine (BSR) à néoformer des pousses feuillées et des racines. Le système racinaire de 23 arbres a été partiellement excavé sur une profondeur de 20 cm. Des BSR de 15 cm de long ont été disposées horizontalement dans des polypropagateurs sur cinq substrats différents, arrosés matin et soir. Le dispositif était un split-plot à trois ré-pétitions. Le traitement principal recouvrait cinq substrats : terre noire (Tn), sable fin (S), sciure de bois (Sc), 50 % Tn/50 % Sc (TnSc) et 50 % Tn/50 % S (Tn-S). Le traitement secondaire distinguait deux classes de diamètre (0,5-1cm ; 1,1-2,5 cm). Après la mise en culture des BSR, le temps de latence d'émer-gence était de 8 semaines pour les pousses aériennes et 12 pour les racines. Après 28 semaines, le pourcentage de pousses feuillées formées variait de 28 % (Tn) à 55 % (S). Les pousses aériennes se sont développées majoritairement (82 %) sur le pôle distal. Le diamètre des BSR a déterminé le déve-loppement des pousses feuillées (P < 0,01). Le taux de bourgeonnement des BSR oscillait entre 21,0 ± 1,8 % pour les BSR de 0,5-1 cm et 86,0 ± 7,8 % pour la classe 1,1-2,5 cm. Le diamètre a également impacté l'enracinement des BSR (P < 0,001). Le taux d'enracinement des BSR variait de 12,0 ± 2,3 % pour les petits diamètres à 59,3 ± 4,7 % pour les plus gros. La multiplication végétative par BSR peut améliorer la filière économique de V. doniana dans les hautes savanes guinéennes du Cameroun.

ABSTrACT VEGETATIVE PROPAGATION Of VITEX DONIANA SWEET fROM ROOT SEGMENT CuTTINGSVitex doniana Sweet is a common multipurpose species in tropical Africa, which has considerable socio-economic importance. Unfortunately, it is extracted from the wild and there has been little or no focused effort to domesticate and cultivate the species. Mastering its propagation through root segment cuttings (RSC) is a real alternative to the difficult process of regeneration from seeds. The aim of our study was to assess two of the key factors (rooting medium and root diameter) that influence its rooting ability. The root system of 23 trees was partially excavated to a depth of 20 cm. Root segment cuttings 15 cm in length were carefully cut and arranged horizontally in a polypropagato...

RESUMEDans le Sahel tchadien, le Balanites aegyptiaca est un arbre de grandes importances socioéconomiques pour les populations. L'objectif de l'étude a été de développer les stratégies de conservation et d'utilisation durable des ressources génétiques de l'espèce. Une enquête socio-économique et un inventaire botanique ont été réalisés auprès de 4 groupes ethniques répartis dans 3 villages. Les analyses botaniques ont porté sur 16 descripteurs morphologiques quantitatifs. Les populations locales ont une bonne connaissance de l'espèce et disposent d'un système de classification empirique utilisant des critères communs ou variables selon le groupe ethnique. Les critères communs aux 4 groupes ont été la taille de l'arbre, les dimensions et la forme du fruit, le goût de la pulpe et la taille des feuilles. Le fruit a été de loin le caractère le plus discriminant. Les descripteurs morphologiques discriminants ont été la longueur du grand axe du fruit (p<0,001), la largeur des feuilles (p<0,05) et la hauteur de l'arbre (p<0,05). Trois morphotypes ont été identifié chez l'espèce dont le plus intéressant regroupe des arbres de grande taille, aux feuilles larges et produisant de longs fruits. Ces informations ouvrent de meilleures perspectives pour la sélection variétale et la domestication de cette espèce dans la zone. © 2016 International Formulae Group.

Del. in the region of Ouaddaï in Chad ABSTRACTBalanites aegyptiaca is a tree of high socioeconomic importance for the population who lives in the Sahelian region of Chad. The aim of this study was to develop any strategies of preservation and sustainable use of the genetic resources of the species. Thus, a socioeconomic survey was carried out within four ethnic groups in three villages and botanical inventory was set up for the purpose. The botanical analyses dealt with 16 quantitative morphological descriptors. The targeted communities have a good knowledge of the species and make use of and empirical classification system based on common or variable criteria according to the ethnical groups under study. The common criteria to the 4 groups were the height of the tree, the size and shape of the fruit, the pulp taste and the length of the leaf. The fruit was by far the most discriminating aspect. The discriminating morphological descriptors were the length of the main axis of the fruit (p <0.001), the width of B. ABDOULAYE et al. / Int. J. Biol. Chem. Sci. 10(4): 1733-1746, 2016 1734 the leaf (p <0.05) and the height of the tree (p <0.05). Three morphotypes were identified in the breed, the most interesting of which concerns high, wide-leafed and long fruit producing trees. This information paves the way for better prospects as far as the selection of varieties and the domestication of the species in the area are concerned.
