ABSTRACT The aim of the study is to use Senna alata L. to remediate soil polluted by spent engine oil (SEO). One hundred and twenty polythene bags filled with 20 kg of soil were separated into two groups A (60) and B (60). Group A contained S. alata seedlings while ...

ABSTRACT The   level   of  accumulation   of   heavy   chemicals   in  the   leaves,   stem   and   roots   of Corchorusolitorius  seedlings  irrigated  with  sewage  (Sewage  effluent)  and  tap  water  to maturity  respectively  was  investigated.  Prior  to  irrigation,  water  quality  indicators  and physico-chemical  properties  of the two  water  sources  were analysed.  The experiment,  a completely ...

ABSTRACT Four organic wastes; mahogany (Khaya ivorensis) sawdust (MSD), Gmelina aborea sawdust (GSD), oil palm fruit fibre (OPFF) and oil palm empty fruit bunch (OPEFB) were evaluated for  their  effects  on  growth,  yield,  quality  and  protein  content  of  Lentinus  squarrosulus (Mont.) Singer. Plastic bag technology was used with  treatments  replicated ...

ABSTRACT The morphology, phenology and seed germination  of the multipurpose African oil bean tree, Pentaclethra macrophylla Benth. belonging to the family Fabaceae were studied. The study area covered   the entire Nsukka zone of Enugu State, Nigeria, and the ten towns randomly selected included: Adani, Amalla Egazi, Ede Oballa, Eha Alumona, ...

ABSTRACT The effect of three basal media, namely; Murashige and Skoog (MS), Gamborg et al. (B5), and Eeuwens (Y3) were assessed for mass propagation of oil palm (Elaeis guineensis Jacq. var. Dura, Pisifera and Tenera) zygotic embryos in vitro. The experimental design was a 3 x 4  factorial  in  a ...

ABSTRACT The aetiology of the fungal rot of cucumber fruit (Cucumis sativus L.) in Enugu State was investigated. Five fungal pathogens were isolated from diseased cucumber fruits. They were identified as Fusarium oxysporum Schlecht, Aspergillus niger Van Tiegh, Rhizopus stolonifer Ehrenb. ex.Fr, Geotrichum candidum Link and Mucor micheli ex Staint ...

ABSTRACT Investigations were conducted to determine the qualitative and quantitative phytohemical properties of  methanolic and aqueous leaf extracts of Chromolaena odorata L., Carica papaya L., and Ocimum gratissimum L. using standard methods. The results revealed that alkaloids, saponins, flavonoids, glycosides, reducing sugars, carbohydrates, steroids, tannins and terpenoids were present in ...

ABSTRACT Qualitative  and  quantitative  screenings of the  leaves  of Eastern Nigerian  mistletoe, Loranthus  micranthus  L.,  parasitic  on  six  different  plant  species  namely,  Kola accuminata, Albizia adiantifolia, Anona cherimola, Citrus sinensis, Citrus auriantifolia and Pentaclethra macrophylla were carried out in the laboratories of Pharmacognosy and Biochemistry Departments of the University of ...

ABSTRACT The water  quality  and  algal diversity of the  stocked  and  unstocked  ponds and  the  dam reservoir at Gesedaddo farms, Yola, Adamawa State, Nigeria, were assessed for ten months. Meteorological data were accessed from Modibbo Adama University of Technology, Yola. Physico-chemical parameters such as temperature, pH, transparency, conductivity dissolved oxygen, ...

ABSTRACT This study was carried out on the nutrient requirements for the in vitro propagation of Ricinus communis employing the basal media of Murashige and Skoog (1962), Gamborg et al. (1968), and Schenk and Hildebrandt (1972) using zygotic embryos as explants. Zygotic embryos were excised from mature seeds and cultured ...

ABSTRACT The effect of three different concentrations of sucrose namely 2, 3 and 4% were investigated on the in vitro regeneration of embryo explants of Treculia africana Decne. on the media of Murashige and Skoog (MS) (1962) and Gamborg et al. (B5) (1968) respectively without any growth regulator. The experimental ...

ABSTRACT The genetic variability among ten (10) accessions of Sphenostylis stenocarpa from three states and National Centre for Genetic Resources and Biotechnology Moor Plantation, Ibadan, Nigeria were assessed using sodium dodecyl polyacrylamide gel electrophoresis (SDS - PAGE). There were variations in the banding patterns of the accessions and polymorphism was ...

ABSTRACT This study investigated locus of control, job status and gender as predictors of perceived job insecurity among bank workers. Two hundred (200) bank workers (122 males and 78 females) drawn from first bank Plc, fidelity bank Plc, zenith bank Plc, Union bank Plc and Access bank Plc all in ...

ABSTRACT The fungitoxic properties of ethanolic and aqueous leaf extracts of Azadirachta indica and Ocimum  gratissimum  used  for  the  control  of  post-harvest  fungal  diseases  of  Solanum melongena were tested in vitro with benlate serving as the standard fungicide and water as the bank control.  Three  fungal  species,  Aspergillus  niger,  Rhizoctonia ...

ABSTRACT A  screen  house  experiment  was  conducted  in  the  Botanical  Garden  of  Plant  Science  and Biotechnology Department, University of Nigeria, Nsukka to assess the effects of refuse  dump compost and poultry manure on the growth and yield of Amaranthus hybridus. The accumulation of heavy metals (Hg, Cu, Cd, Zn, Pb ...

ABSTRACT The physico-chemical and  algal characteristics of the upper reaches of Ebonyi River were studied in four stations over a four- month period from September to December 2014. The physico-chemical parameters: air and water temperatures, colour, depth, rate of flow, transparency, pH, Total Dissolved Solids (TDS), alkalinity, Biochemical Oxygen Demand ...

ABSTRACT Morpho- anatomical features of leaf, rachis, stem (bark), root, fruit, flower and pollen of Albizia adianthifolia (Schum.)W.F. Wight and Albizia chevalieri Harms. were studied with the goal to assess the taxonomic (pleisomorphic and apomorphic) characters in the two species, as well as to explore the agricultural and functional wood ...

ABSTRACT Sodium Dodecyl Sulphate -  Polyacrylamide Gel Electrophoresis (SDS -  PAGE) is  a technique commonly used for the separation of proteins according to their molecular weight, based on their differential rates of migration through a sieving matrix (a gel) under the influence of an applied electrical field. SDS - PAGE ...

ABSTRACT Jatropha curcas L. (physic nut) is a multipurpose plant which belongs to the  family  Euphorbiaceae.  The  non-edible  oil  produced  from  the  seeds  is considered a potential renewable source of biodiesel. This research aims at estimating the optimum sucrose concentration for in vitro plantlet regeneration using mature zygotic embryos as ...

ABSTRACT This study has been undertaken to investigate the physicochemical properties and the bacterial population of the rhizosphere of Sorghum vulgare. In order to simulate spillage, 0.2, 0.9 and 5.0 % v/w concentrations of crude oil were used to contaminate soil sown with seeds of Sorghum vulgare, while the control ...
