The cashew sector has taken a great economic interest, due to the strong global demand for raw nuts. However, in Burkina Faso, the productivity of orchards still remains low, a consequence of a lack of breeding program on the species. In order to increase yields and improve the quality of the raw nut, efficient clones must be developed. Surveys were carried out and a primary in situ collection was made from which a core collection of 15 trees was extracted. An agro-morphological description of the selected trees and an analysis of the structuration of the variability within them were carried out. The study revealed appreciable agro-morphological diversity through shape, size and color of apple, type of inflorescence, fruiting period and the health of trees. A structure of diversity based on agronomic criteria led to identify 5 groups of trees, characterized by an average weight of the nut between 6.64 and 8.32 g, a kernel rate between 28.10 and 31.26% and a yield per tree between 34.27 and 104.42 kg. Performing trees will be erected as heads of clones for the production of grafted plants. La filière anacarde a pris un grand intérêt économique, suite à la forte demande mondiale en noix brutes. Cependant, au Burkina Faso, la productivité des vergers demeure encore faible, conséquence d’une absence de sélection variétale du matériel végétal. En vue d’accroître les rendements et d’améliorer la qualité de la noix brute, une recherche de clones performants était indispensable. Des prospections ont été conduites et une collection primaire in situ a été constituée dont une core collection de 15 arbres a été extraite. Une description agro-morphologique des arbres sélectionnés et une analyse de la structuration de la variabilité en son sein ont été conduites. L’étude a révélé une diversité agro morphologique appréciable à travers la forme, le calibre et la couleur de la pomme, le type d’inflorescence, la période de fructification et l’état sanitaire des arbres. Une structuration de la diversité basée sur les critères agronomiques a permis d’identifier 5 groupes d’arbres, caractérisés par un poids moyen de la noix compris entre 6,64 et 8,32 g, un taux d’amande compris entre 28,10 et 31,26% et un rendement par arbre compris entre 34,27 et 104,42 kg. Les arbres les plus performants constitueront des têtes de clones pour la production de plants par greffage.

In Situ Collection

Abstract. A technique for collecting aerosol particles between altitudes of 17 and 85 km is described. Spin-stabilized collection probes are ejected from a sounding rocket allowing for multi-point measurements. Each probe is equipped with 110 collection samples that are 3 mm in diameter. The collection samples are one of three types: standard transmission electron microscopy carbon grids, glass fibre filter paper or silicone gel. Collection samples are exposed over a 50 m to 5 km height range with a total of 45 separate ranges. Post-flight electron microscopy will give size-resolved information on particle number, shape and elemental composition. Each collection probe is equipped with a suite of sensors to capture the probe's status during the fall. Parachute recovery systems along with GPS-based localization will ensure that each probe can be located and recovered for post-flight analysis.

High-strength and micropore lightweight bauxite aggregate was fabricated by low grade raw bauxite powder, aluminium hydroxide powder and organic polymer (OP). OP was used as consolidator, binder and pore former and aluminium hydroxide was used as pore former. The influence of OP and aluminium hydroxide content on the property of the samples was studied. The phase composition and the microstructure of the sintered samples were characterized by XRD, SEM and the pore size distribution was measured by mercury porosimety. The results demonstrate that the bulk density of the samples decreases linearly and the apparent porosity of the samples increases gradually with the addition of OP. The lowest density reached 1.13g/cm3when adding 35% OP and 10% Al(OH)3. The average pore size is around 5μm, and increases with the addition of OP increased. The XRD showed the main phase of the sample is mullite and some little amount of corundum.
