Caractères morphologiques deDetarium microcarpumGuill. et Perr. au sud du Mali

Abstract

Introduction. Detarium microcarpum is an important fruit-bearing species in the south of Mali. The objective of this work was the morphological characterization of certain populations of D. microcarpum, which would be a necessary step for a subsequent study of the genetic structure of the species. Materials and methods. Morphological observations related to twenty-three agronomic characters, studied on twenty-five trees selected from ten populations located in southern Mali. Results and discussion. The study showed that there was a variability between the populations, which related to the characters measured on the fruit, the seed and the leaf. Three shapes of mature fruit and one shape of seed were identified. Conclusion. Results obtained do not make it possible to affirm the existence of different varieties within the species D. microcarpum. The study will thus have to be extended to the observation of other characters, and relate to the whole of the D. microcarpum distribution area in the Sahel.

Detarium microcarpum est une espèce fruitière importante au sud du Mali. L'objectif du présent travail a été la caractérisation morphologique de certaines populations de D. microcarpum, qui serait un préalable nécessaire à l'étude de la structure génétique de l'espèce. Matériel et méthodes. Les observations morphologiques ont concerné vingt-trois caractères agronomiques étudiés sur 25 arbres par peuplement de dix populations réparties sur l'ensemble du sud du Mali. Résultats et discussion. L'étude a montré qu'il existait une variabilité entre les populations, qui a porté sur les caractères mesurés chez le fruit, la graine et la feuille. Trois formes de fruits à maturité et une forme de graines ont été identifiées. Conclusion. Les résultats obtenus ne permettent pas d'affirmer l'existence de variétés différentes au sein de l'espèce D. microcarpum. L'étude devra donc être élargie à l'observation d'autres caractères et porter sur l'ensemble de l'aire de répartition de l'espèce au Sahel.

Geographical distribution, tree density and fruit production ofTamarindus indicaL. (Fabaceae) across three ecological regions in Benin

“…This is also to provide marketable products from farms that will generate income for resource-poor rural households. As such, it has led to an increasing interest in the domestication potential of some traditionally valued agroforestry trees in Africa, i.e., Detarium microcarpum Harms [2], Irvingia gabonensis (Aubry Lecomte ex O'Rorke) Baill. [3] and Sclerocarya birrea (A.Rich.)…”

“…Firstly, they help to fulfill households' subsistence and consumption needs in terms of energy and nutrition as well as medical and construction purposes. Secondly, they serve as a safety-net in times of crises (e.g., income shortages due to crop failure) and thirdly, some AFTPs provide regular cash income (Kouyaté 2005;Kalinganire et al 2007).…”

“…A number of studies provided a description of the functions of some of the major species found in Sahelian parklands indicating that agroforestry tree products (AFTPs) can play three main functions in the household economy of rural communities living in or adjacent to the parkland (Kouyaté 2005;Kalinganire et al 2007). Firstly, they help to fulfill households' subsistence and consumption needs in terms of energy and nutrition as well as medical and construction purposes.…”
