In situ conservation is primarily focused on conserving the species in its natural environment by preserving its adaptation potential over the long term (FAO et al., 2001), while ex situ strategies are based on creating gene banks or field collections, transferring genetic resources off site, for the purpose of conservation or breeding (Dunster, 1996). Although P. biglobosa is officially protected by national legislation in Burkina Faso and in other West African countries (Eyog Matig et al., 2002) and cutting is prohibited, genetic con- servation efforts need to be strengthened.

  • Moisture Dependent Mechanical and Thermal Properties of Locust Bean (Parkia Biglobosa)
    March, 2014 Agric Eng Int: CIGR Journal Open access at http://www.cigrjournal.org Vol. 16, No.1 99 Moisture dependent mechanical and thermal properties of Locust bean (Parkia biglobosa) Olajide Ayodele Sadiku1*, Isaac Bamgboye2 (1. Department of Agronomy, Faculty of Agriculture and Forestry, University of Ibadan, Ibadan, Nigeria; 2. Department of Agricultural and Environmental Engineering, Faculty of Technology, University of Ibadan, Ibadan, Nigeria) Abstract: The mechanical and thermal properties of African locust bean (Parkia biglobosa) seeds were investigated as a function of moisture content in the range of 5.9%–28.2% dry basis (d.b.). These properties are required for the engineering design of equipment for handling and processing locust bean. Universal Testing Machine was used to determine the mechanical properties at 5 mm/min load rating transversely. Normal and shear stresses were determined for 200–500 g loads at 100 g interval. Specific heat and thermal conductivity were determined using the method of mixtures and steady-state heat flow method respectively. Linear decreases in rupture force (214.42–129.86 N) and rupture energy (109.17–73.46 N mm) were recorded, while deformation of the seed samples increased (0.98-1.13 mm). Linear increase in normal stress at 200, 300, 400 and 500 g loads were 8.38–8.69, 9.39–9.70, 10.40–10.71 and 11.41–11.72 g/cm2 respectively, while shear stress ranged from 0.589 to 0.845, 0.688 to 0.998, 0.638–1.213 and 0.688–1.359 g/cm2 at 200, 300, 400 and 500 g with increasing seed moisture content.

We combine published molecular data for the chloroplast regions matK and rbcL with 66 morphological characters surveyed for 73 ingroup and two outgroup species, and use Parsimony and Bayesian approaches to explore matrices with different missing data. All combined analyses using Parsimony recovered the topology Polygalaceae (Leguminosae (Quillajaceae + Surianaceae)). Bayesian analyses with matched morphological and molecular sampling recover the same topology, but analyses based on other data recover a different Bayesian topology: ((Polygalaceae + Leguminosae) (Quillajaceae + Surianaceae)). We explore the evolution of floral characters in the context of the more consistent topology: Polygalaceae (Leguminosae (Quillajaceae + Surianaceae)). This reveals synapomorphies for (Leguminosae (Quillajaceae + Suri- anaceae)) as the presence of free filaments and marginal ⁄ ventral placentation, for (Quillajaceae + Surianaceae) as pentamery and apocarpy, and for Leguminosae the presence of an abaxial median sepal and unicarpellate gynoecium. An octamerous androecium is synapomorphic for Polygalaceae. The development of papilionate flowers, and the evolutionary context in which these phenotypes appeared in Leguminosae and Polygalaceae, shows that the morphologies are convergent rather than synapomorphic within Fabales.

  • 30Th RAU Abstract Book
    1 2 Dear colleagues, On behalf of the Organizing Committee, I am pleased to welcome all the participants to the 30th edition of the Annual Users Meeting of the Brazilian Synchrotron Light Laboratory- RAU/LNLS. I would like to start by wishing you and your families my personal best for your health and safety in these difficult times. This year has tested us like no other. RAU is a unique opportunity to gather together the Brazilian lightsource community in a single scientific event to disseminate results and exchange ideas. Following much debate, we decided to proceed with the RAU in the now realized alternative format. This was not without its own challenges. The year 2020 marks the 30th anniversary of this Users Meeting. Although RAU is being run under exceptional circumstances, we have created what we hope will be a RAU to be remembered for many years to come. 30th RAU will be four days long bringing together around 500 researchers from different corners of Brazil and from more than 20 countries around the world. The programme includes 114 poster presentations, 20 oral contributions, 4 keynote talks and 6 invited plenary lectures. In addition, we will have an overview of LNLS, Sirius virtual tour, meetings with beamline coordinators, and last but not the least, the newly elected User Committee will be presented during the LNLS Users Group assembly. The structure of this RAU was designed to stimulate discussion and participation. All sessions will have life in them. We certainly encourage all participants to attend and engage with sessions as though you were here in person.

  • Melliferous Plants for Cameroon Highlands and Adamaoua Plateau Honey
    Melliferous plants for Cameroon Highlands and Adamaoua Plateau honey April 2011 i Melliferous plants for Cameroon Highlands and Adamaoua Plateau honey A melliferous flower is a plant which produces substances that can be collected by insects and turned into honey. Many plants are melliferous, but only certain plants have pollen and nectar that can be harvested by honey bees (Apis mellifera adansonii in Cameroon). This is because of the bee’s physiognomy (their body size and shape, length of proboscis, etc.) A plant is classified as melliferous if it can be harvested by domesticated honey bees. This is a symbiotic relationship (both organisms benefit), with bees collecting nectar, and pollen for food, and useful plant substances to make propolis to fill gaps in the hive. Plants benefit from the transfer of pollen, which assures fertilization. The tables of 1. Native & Forest Plants, April 2011 i Melliferous plants for Cameroon Highlands and Adamaoua Plateau honey 2. Exotic, Agroforestry & Crop Trees and 3. Bee hating trees list many of the known melliferous plants in the Cameroon Highlands and Adamaoua Plateau. This is the mountain range stretching from Mt Oku in the Northwest, through the Lebialem Highlands and Dschang , to Mt Kupe and Muanengouba and to Mt Cameroon in the Southwest. The information presented covers the flowering period, the resources harvested by bees (Nectar, pollen, propolis, and honeydew). It is worth noting that each plant does not produce the same quantity or quality of these resources, and even among species production varies due to location, altitude, plant health and climate.

RECONSTRUCTING THE PHYLOGENY OF LEGUMES (LEGUMINOSAE): AN EARLY 21ST CENTURY PERSPECTIVE MARTIN F. WOJCIECHOWSKI Department of Plant Biology, Arizona State University, Tempe, Arizona 85287 USA Abstract Elucidating the phylogenetic relationships of the legumes is essential for understanding the evolutionary history of events that underlie the origin and diversification of this family of ecologically and economically important flowering plants. In the ten years since the Third International Legume Conference (1992), the study of legume phylogeny using molecular data has advanced from a few tentative inferences based on relatively few, small datasets into an era of large, increasingly multiple gene analyses that provide greater resolution and confidence, as well as a few surprises. Reconstructing the phylogeny of the Leguminosae and its close relatives will further advance our knowledge of legume biology and facilitate comparative studies of plant structure and development, plant-animal interactions, plant-microbial symbiosis, and genome structure and dynamics. Phylogenetic relationships of Leguminosae — what has been accomplished since ILC-3? The Leguminosae (Fabaceae), with approximately 720 genera and more than 18,000 species worldwide (Lewis et al., in press) is the third largest family of flowering plants (Mabberley, 1997). Although greater in terms of the diversity of forms and number of habitats in which they reside, the family is second only perhaps to Poaceae (the grasses) in its agricultural and economic importance, and includes species used for foods, oils, fibre, fuel, timber, medicinals, numerous chemicals, cultivated horticultural varieties, and soil enrichment.
