Previous analyses of species relationships and polyploid origins in the mimosoid legume genus Leucaena have used chloroplast DNA (cpDNA) restriction site data and morphology. Here we present an analysis of a new DNA sequence data set for the nuclear ribosomal DNA (nrDNA) 5.8S subunit and flanking ITS 1 and ITS 2 spacers, a simultaneous analysis of the morphology, ITS and cpDNA data sets for the...

This study was conducted to valorize four sources of fiber (Gliricidia sepium, Leucaena leucocephala, Moringa oleifera and palm nut fibers) in animal production. The experiments were carried out on 128 rabbits divided into 4 batches 32 animals, reared for 8 weeks under the same conditions. Each batch subdivided two subgroups, one fed with a complete diet (a containing served all day) other sepa...

Tree growth, biomass productivity, litterfall mass and nutrient content, changes in soil chemical properties and understory forest succession were evaluated over a 8.5-year period in singleand mixed-species (50 : 50) plantations of two N2-®xing species, Casuarina equisetifolia and Leucaena leucocephala, and a non-®xing species, Eucalyptus robusta. At the optimal harvest age for maximum biomass ...

13 The nutritive value of 20 forage plants commonly used for feeding pigs in the Democratic 14 Republic of the Congo was studied to determine chemical composition, protein amino acid 15 profiles, mineral content, and in vitro digestibility using a two-steps method combining an 16 enzymatic pepsin and pancreatin hydrolysis followed by a 72h gas-test fermentation. The 17 highest protein contents ...

It is a great challenge for researchers to select plant species in terms of their physiological and root properties for vegetation on slope. Therefore, this study was aimed to investigate the physiology and root profile of four selected tropical plants namely Leucaena leucocephala (LL), Adenanthera pavonina (AP), Peltophorum pterocarpum (PP) and Pterocarpus indicus (PI). The species studied wer...

An experimental trial was conducted at Dhabeji area to see the effect of chemical industry waste (organic with heavy metals) on seed bank of barren area of Dhabeji. An industrial sludge and its ash content were used in different concentrations, 10Kg and 20Kg sludge, 10kg and 20kg ash respectively to see the effect on seed bank, germination and growth of wild plants. After rainfall 17 species ap...

The intensification of beef cattle production in dryland areas of East Indonesia has the potential to substantially raise the incomes of smallholder farmers that dominate the sector. In this study we assess the potential for intensifying beef production on Sumbawa Island, by introducing a household feedlot production system (2-20 animals) based on the Leucaena leucocephala (leucanea) tree legum...

The tree legume leucaena (Leucaena leucocephala) is rich in protein content, but it also contains the toxin mimosine. A set of genes involved in mimosine degradation has been identified from Rhizobium TAL1145. TAL1145 degrades mimosine in two steps: the mid genes encode enzymes that break down mimosine to 3-hydroxy-4-pyridone (HP); HP is further degraded by a dioxygenase and a hydrolase, encode...
