Morphological variability within the indigenous sheep population of Benin
19 octobre 2021, HE CondorcetArticle scientifiqueKnowledge of both the genetic diversity and geographical distribution of animal genetic resources is a prerequisite for their sustainable utilization, improvement and conservation. The present study was undertaken to explore the current morphological variability within the sheep population in Benin as a prelude for their molecular characterization. From November 2018 to February 2020, 25 quantitative ... -
Construction of a Novel Chimeric Dextransucrase Fused to the Carbohydrate-Binding Module CBM2a
28 septembre 2021, HE CondorcetArticle scientifiqueLactic acid bacteria (LAB) have the potential to produce homoexopolysaccharides (HoPS). Their health benefits and physicochemical properties have been the subject of extensive research. The HoPS functional properties are determined by molecular weight, the type of glycosidic link ages, degrees of branching and chemical composition. The dextransucrases (DSases) produce a kind of HoPS (dextrans), ... -
Biodiversity of Fusarium species in ears and stalks of maize plants in Belgium
21 avril 2011, CARAHArticle scientifiqueIn order to investigate the pre-harvest contamination of maize plants by Fusarium species in Belgium, a three-year survey has been performed in five fields in which three hybrids differing in susceptibility to maize stalk rot were sampled at four different physiological stages. An extensive collection of 5,659 Fusarium isolates characterized at the species level was established during the 2005, 2006, ... -

Les principaux résultats obtenus sont: l’inhibition presque complète de la prolifération par la BAP; l’inhibition totale de l’enracinement par la concentration de 10 µM BAP+10 µM MemTR, l’amélioration de la prolifération moyenne de ... -
Acclimatation de vitroplants de bananier (Musa sp.) en culture hydroponique : impact de différentes concentrations en cuivre sur la croissance des vitroplants
janvier 2013, HE CondorcetCARAHArticle scientifiqueLes contraintes dues au cuivre et les conséquences de son accumulation par les vitroplants de bananier pendant la phase d’acclimatation ont été étudiées en culture hydroponique. Des doses de 0-100-500-1000 ppm de cuivre, sous forme de CuSO4, ont été ajoutées au milieu nutritif en culture hydroponique. A 1000 ppm CuSO4, les résultats obtenus ont mis en évidence des concentrations en cuivre élevées ... -
Étude de l'acclimatation en serre de vitroplants de bananiers de la FHIA : "cas de FHIA-01 AAAB et FHIA-23 AAAA"
31 janvier 2014, HE CondorcetCARAHArticle scientifiqueLes plants issus de la culture in vitro nécessitent une période d'acclimatation avant leur transfert au champ. Dans cette étude, la réponse des vitroplants de bananier aux fluctuations des températures et des quantités d'eau a été évaluée, lors de la phase d'acclimatation. Méthodologie et résultats : Dans le premier essai utilisant des vitroplants du bananier plantain, hybride FHIA-23 groupe AAAA, ... -

Exploiting Genetic Variability of Root Morphology as a Lever to Improve Nitrogen Use Efficiency in Oilseed Rape
29 juillet 2018, HE CondorcetCARAHLivre/Ouvrage ou monographieNitrogen (N) is the quantitatively most important nutrient in cropping systems. The use of nitrate as a mineral fertilizer is highly energy-intensive and causes greenhouse gas emission and groundwater pollution. Therefore, the need to reduce N-fertilizer input is pressing. In order to compensate that reduction, new crop genotypes must be sought with improved nitrogen use efficiency (NUE). While ... -
Root Morphological Traits of Seedlings Are Predictors of Seed Yield and Quality in Winter Oilseed Rape Hybrid Cultivars
15 octobre 2020, HE CondorcetCARAHArticle scientifiqueThe root system is responsible for soil resources acquisition. Hence, optimizing crop root characteristics has considerable implications for agricultural production. This study evaluated a panel of twenty-eight European modern cultivars of oilseed rape (Brassica napus L.) cultivated in laboratory and field environments. Root morphology was screened using a high-throughput hydroponic growth system ... -
In-Field Observation of Root Growth and Nitrogen Uptake Efficency of Winter Oilseed Rape
10 janvier 2020, HE CondorcetCARAHArticle scientifiqueField trials were conducted with two nitrogen applications (0 or 240 kg N ha−1) and three modern cultivars of winter oilseed rape (Brassica napus L.) previously selected from a root morphology screen at a young developmental stage. The purpose is to examine the relationship between root morphology and Nitrogen Uptake Efficiency (NUpE) and to test the predictiveness of some canopy optical indices for ... -
Quel comportement de développement adoptent les rameaux de la vigne après une gelée printanière ?
29 avril 2021, HE CondorcetCARAHArticle scientifiqueL'épisode gélif que nous avons connu en ce début avril nous rappelle combien la météo peut impacter les cultures, notamment fruitières et viticoles. Un tel phénomène s'est également produit l'année dernière, en mai, alors que les vignes se trouvaient à un stade particulièrement sensible de leur développement. À cette occasion, le Carah a observé et analysé comment les différents cépages de son ... -
La dégradabilité des plastiques en culture de maïs : sous l'effet des micro-organismes et de la lumière, avec quels résultats et améliorations possibles ?
22 avril 2021, HE CondorcetCARAHArticle scientifique[Disponible sur le site du sillon belge]La culture de maïs sous plastique soulève de nombreuses interrogations, notamment en matière d’environnement. Pour éclaircir cette problématique, le Carah a passé au crible différents types de plastique et a étudié plus précisément leur dégradabilité. Ces essais en laboratoire ont ensuite été complétés par une évaluation au champ, sous la houlette du Cipf. En ... -
Cardiorespiratory responses during running and sport-specific exercises in handball players
mai 2009, HE CondorcetArticle scientifiqueTo determine whether a 4-a-side handball (HB) game is an appropriate aerobic stimulus to reach and potentially enhance maximal oxygen uptake (V˙O2max), and whether heart rate (HR) is a valid index of V˙O2 during a handball game. Nine skilled players (21.0 ± 2.9 yr) underwent a graded maximal aerobic test (GT) where V˙O2max and HR−V˙O2 relationship were determined. V˙O2, HR and blood lactate ([La]b) ... -
Accuracy of Medical Oxygen Flowmeters: A Multicentric Field Study
août 2014, HE CondorcetArticle scientifiqueThe accuracy of 476 oxygen flowmeters was investigated using a thermal mass flowmeter in eight hospitals in France and Belgium. Different oxygen flow rates (2 to 15 l/min) were evaluated at the patient’s bed. When the sample was considered as a whole, the accuracy of delivered flow was acceptable but precision was poor. The variability of the delivered flow between devices was greater when a low ... -
Effect of dietary nitrate supplementation on tolerance to supramaximal intensity intermittent exercise
29 mai 2015, HE CondorcetArticle scientifiqueDietary nitrate (NO3−) supplementation has been shown to increase exercise tolerance and improve oxidative efficiency during aerobic exercise in healthy subjects. We tested the hypothesis that a 3-day supplementation in beetroot juice (BJ) rich in NO3− would improve the tolerance to supramaximal intensity intermittent exercise consisting of 15-s exercise periods at 170% of the maximal aerobic power ... -
Effect of dietary nitrate supplementation on metabolic rate during rest and exercise in human: A systematic review and a meta-analysis
16 janvier 2016, HE CondorcetArticle scientifiqueBackground Recent randomized controlled trials have suggested that dietary nitrate (NO3-), found in beetroot and other vegetables, and inorganic NO3− salts decrease metabolic rate under resting and exercise conditions. Objective Our aim was therefore to determine from a systematic review and meta-analysis whether dietary NO3− supplementation significantly reduces metabolic rate, expressed as ... -
Bilateral Strength Deficit Is Not Neural in Origin; Rather Due to Dynamometer Mechanical Configuration
18 décembre 2015, HE CondorcetArticle scientifiqueDuring maximal contractions, the sum of forces exerted by homonymous muscles unilaterally is typically higher than the sum of forces exerted by the same muscles bilaterally. However, the underlying mechanism(s) of this phenomenon, which is known as the bilateral strength deficit, remain equivocal. One potential factor that has received minimal attention is the contribution of body adjustments to ... -
