Diversity, abundance and seasonal dynamic of zooplankton community in a south-saharan reservoir (Burkina Faso).
Ouéda Adama, Guenda Wendengoudi, Kabré André T., Zongo Frédéric et Kabré Gustave Boureima
From May 2004 to April 2005, the zooplankton of the Loumbila reservoir was subject to a 14 days periodicity follow-up. This study attempt to describe the diversity, abundance and seasonal dynamic of zooplankton community in a south-saharian reservoir. Plankton community was sampled with horizontal tows of a plankton net of 100 urn mesh size. T(...)

Etudes Phytochmiques des feuilles de Rytigynia Canthioides (Benth.) Robyns (Rubiaceae), une plante Medicinale et Alimentaire du BéninINALE ET ALIMENTAIRE UTILISEE AU BENIN
AGASSOUNON DTM, F Toukourou, C SOUZA, Mamoudou H. DICKO, AS Traoré, Gbeassor
Phytochemical studies carried out on the leaves of Rytigynia canthioides (Benth.) Robyns with regard to the content of organic and mineral substances and the presence of active principles have given satisfactory results. Our results revealed that Rytigynia canthioides contain proteins, lipids, sugar and polyphenols with the contents varying fr(...)

Sorghum Grain as Human Food in Africa: Relevance of Starch Content and Amylase Activities
132. DICKO Mamoudou. H., GRUPPEN, H., TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J
Sorghum is a staple food grain in many semi-arid and tropic areas of the world, notably in Sub-Saharan Africa because of its good adaptation to hard environments and its good yield of production. Among important biochemical components for sorghum processing are levels of starch (amylose and amylopectin) and starch depolymerizing enzymes. Curre(...)

Evaluation of the Effect of Germination on Phenolic Compounds and Antioxidant Activities in Sorghum Varieties
DICKO Mamoudou. H.,, GRUPPEN, H.; ZOUZOUHO O.C.; TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J.
The screening of 50 sorghum varieties showed that, on average, germination did not affect the content in total phenolic compounds but decreased the content of proanthocyanidins, 3-deoxyanthocyanidins, and flavan-4-ols. Independent of germination, there are intervarietal differences in antioxidant activities among sorghum varieties. Phenolic co(...)

Phenolic Compounds and Related Enzymes as Determinants of Sorghum for Food Use
DICKO Mamoudou. H., GRUPPEN, H., TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J.
Phenolic compounds and related enzymes such as phenol biosynthesizing enzymes (phenylalanine ammonia lyase) and phenol catabolizing enzymes (polyphenol oxidase and peroxidase) are determinants for sorghum utilization as human food because they influence product properties during and after sorghum processing. Phenolic compounds are quality-grad(...)

Régénération sexuée de Boswellia dalzielii Hutch., un arbre médicinal de grande valeur au Burkina Faso
Amadé Ouedraogo, Adjima Thiombiano, Karen Hahn-Hadjali, Sita Guinko
Résumé Boswellia dalzielii Hutch. est une plante principalement utilisée en pharmacopée traditionnelle. Elle compte parmi les espèces les plus menacées à l'est du Burkina Faso. L'espèce subit un écorçage intensif, qui la met en péril, et sa régénération est faible. Une collecte de fruits a été réalisée dans plusieurs peuplements pour étudier l(...)

Adaptative response of two varieties of cowpeas to water stress
HAMIDOU, F., Mamoudou H. DICKO ZOMBRE, G., TRAORE, A. S., and GUINKO, S
This study examined the adaptive response of the cowpea (Vigna unguiculata (L.) Walp.) to water stress at the beginning of pod formation. The regulation of carbohydrate levels, sucrose and starch in particular, was monitored in two varieties: local Gorom and KN1. In addition, the specific leaf mass and components of yield were studied. When th(...)

Impact of Phenolic Compounds and Related Enzymes in Sorghum Varieties for Resistance and Susceptibility to Biotic and Abiotic Stresses
DICKO Mamoudou. H., GRUPPEN, H., Barro, C.; TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J
Contents of phenolic compounds and related enzymes before and after sorghum grain germination were compared between varieties either resistant or susceptible to biotic (sooty stripe, sorghum midge, leaf anthracnose, striga, and grain molds) and abiotic lodging, drought resistance, and photoperiod sensitivity) stresses. Independent of grain ger(...)
