| aflp fingerprint analysis of bradyrhizobium strains isolated from faidherbia albida and aeschynomene species. | the diversity of bradyrhizobium isolates from faidherbia albida and aeschynomenee species was assessed using aflp analysis, a high-resolution genomic fingerprinting technique. reference strains from bradyrhizobium japonicum, bradyrhizobium elkanii and bradyrhizobium liaoningense were included for comparison. at a similarity level of 50%, a total of 34 different groups were obtained by cluster analysis of the genomic fingerprints. four of these clusters correspond to the three reference species, ... | 2000 | 10879988 |
| bradyrhizobium sp. strains that nodulate the leguminous tree acacia albida produce fucosylated and partially sulfated nod factors. | we determined the structures of nod factors produced by six different bradyrhizobium sp. strains nodulating the legume tree acacia albida (syn. faidherbia albida). compounds from all strains were found to be similar, i.e., o-carbamoylated and substituted by an often sulfated methyl fucose and different from compounds produced by rhizobium-mesorhizobium-sinorhizobium strains nodulating other species of the acaciae tribe. | 2000 | 11055966 |
| feeding strategies during dry summer for lactating desert goats in a rainfed area under tropical conditions. | feeding strategies aimed at improving the nutritive value of crop residues through chemical treatment or utilizing other available feed resources as small ruminant feeds were carried out during the hot dry summer season when rangeland pasture deteriorates drastically. the study utilized small-scale farmer animals and crop residues chemically treated as animal feeds. other feeds were groundnut haulms (gnh) and tree pods (tp) of faidherbia albida. a total of 30 adult lactating goats with their kid ... | 2001 | 11182309 |
| dna-dna hybridization study of bradyrhizobium strains. | dna-dna hybridizations were performed between bradyrhizobium strains, isolated mainly from faidherbia albida and aeschynomene species, as well as bradyrhizobium reference strains. results indicated that the genus bradyrhizobium consists of at least 11 genospecies, i to xi. the genospecies formed four subgeneric groups that were more closely related to each other (>40% dna hybridization) than to other genospecies (<40% dna hybridization): (i) genospecies i (bradyrhizobium japonicum), iii (bradyrh ... | 2001 | 11491327 |
| ethnobotanical study of homegarden plants in sebeta-awas district of the oromia region of ethiopia to assess use, species diversity and management practices. | homegardens in ethiopia are currently facing different threats mainly due genetic erosion, loss of traditional knowledge on their use and management and drought. on the other hand, research and documentation works on homegardens in the country are very limited. there is no previous report indicating conduct of ethnobotanical study on homegardens in selected study district. the present study thus attempted to document knowledge on uses and management practices of homegardens by people in study di ... | 2015 | 26296364 |
| variation in the response of eastern and southern africa provenances of faidherbia albida (delile a. chev) seedlings to water supply: a greenhouse experiment. | rural communities value faidherbia albida in farming systems and pastoralism. faidherbia albida provides products such as medicine, fodder, fuel, wood, food and services such as shade, soil fertility and nutrient cycling. excessive browsing by animals, branch lopping and pod harvesting, have critically reduced the natural regeneration in some areas which exposes it to challenges due to dependence upon natural regeneration. the objective of this research was to evaluate response of faidherbia alb ... | 2016 | 28203619 |
| widespread dieback of riparian trees on a dammed ephemeral river and evidence of local mitigation by tributary flows. | ephemeral rivers act as linear oases in drylands providing key resources to people and wildlife. however, not much is known about these rivers' sensitivities to human activities. we investigated the landscape-level determinants of riparian tree dieback along the swakop river, a dammed ephemeral river in namibia, focusing on the native ana tree (faidherbia albida) and the invasive mesquite (prosopis spp.). we surveyed over 1,900 individual trees distributed across 24 sites along a 250 km stretch ... | 2016 | 27812420 |
| identification of symbiotic nitrogen-fixing bacteria from three african leguminous trees in gorongosa national park. | the symbiosis between leguminous plants and symbiotic nitrogen-fixing bacteria is a key component of terrestrial ecosystems. woody legumes are well represented in tropical african forests but despite their ecological and socio-economic importance, they have been little studied for this symbiosis. in this study, we examined the identity and diversity of symbiotic-nitrogen fixing bacteria associated with acacia xanthophloea, faidherbia albida and albizia versicolor in the gorongosa national park ( ... | 2016 | 27287843 |
| allozyme variation in 16 natural populations of faidherbia albida (del.) a. chev. | the objectives of this study were (1) to investigate the genetic variability; and (2) to determine the phylogenetic relationship in the leguminous tree faidherbia albida through out its range of distribution in east, west and southern africa. a total of 16 populations were subjected to enzyme electrophoresis and 6 enzyme systems (adh, mdh, g6pdh, idh, 6pgdh, and alpha-est) encoded by 12 loci were scored. a total of fifty one different alleles were detected, with an average of 2.5 alleles per loc ... | 2000 | 11338426 |
