ABSTRACT The oreation o f the Volta Lake in Ghana provides favourable conditions fo r rapid weed growth,, The present report represents an attempt to in v e s t ig a te the in te ra c t ion between one o f the economically important weeds on the Lake, P is t ia s t r a t io t e s , L ., an the physicochemical condition o f i t s environment in the f i e l d and laboratory, P is t ia is represented in most reaches o f the Lake but only sheltered bays and es tu arie s in the south are o...
ABSTRACT The natural Radial and axial variations in the resistance of the wood of Termihalia ivorensis A* Chev, against damage by subterranean termites were investigated for two trees from the same locality- The damage was studied in relation to specific gravity, the modulus of elasticity, the cross-sectional area of vessels in the wood,, and the water soluble extractives. The correlation between termite damage and these physical, mechanical and anatomical properties have been reported. It wa...
ABSTRACT Millet, a widely consumed food crop, is subject to fungal contamination during storage. These fungi produce mycotoxins in stored food products. Mycotoxins such as citrinin and ochratoxin produced by Penicillium species have been reported to be injurious to consumers. Knowledge of the fungi involved in the production of these mycotoxins will help in the control of its spread in food products. However, there is dearth of information on the mycotoxins produced by Penicillium on millet ...
Abstract The study was undertaken in the Afadjato Community Forest Conservation Area between August 2010 and June 2011 with the following objectives: 1. To document and analyse the diversity of plants in the Afadjato Community Forest Conservation Area. 2. To undertake a quantitative ethnobotanical study of traditional knowledge and plant use among local people living in the study area. 3. To explore the relationship between plant diversity and use; and 4. To determine the conservation and ec...
ABSTRACT Investigations were conducted with four pot and two field experiments on the influence of vesicular arbuscular mycorrhiza (VAM), and fertilization on chili pepper, Capsicum annuum var. tatase (Yoruba) in different cropping systems. All experiments were factorial in a randomized complete block design (RCBD) and each treatment was replicated three times. The first two pot experiments carried out in the Department of Botany and Microbiology, University of Ibadan under natural solar il...
ABSTRACT Macrophytes such as Eichhornia crassipes and Pistia stratiotes are known bioaccumulators found in the Ologe Lagoon which receives effluents mainly from Agbara Industrial Estate. However, the mechanism of heavy metal bioaccumulation by these macrophytes has not been fully understood. This study was designed to determine the mechanism of heavy metal bioaccumulation and model the phytoremediation capabilities of the macrophytes. Five sampling stations: Owo (before the point of dischar...
ABSTRACT Six species of known toxigenic and zoopathogenic fungi were isolated from Nigerian poultry feeds. These include Aspergillus flavus Link: Fr. (IMI 280819), A. fumiga tus Fres. (1M1 280822), ~ niger v. Tieghem (IM1 280823), A. oryzae (Ahlburg) Cohn (IM1 280831), Rhizopus arrhizus Fischer (1M1 280827) and Rhizomucor pusillus Lindt Schipper (1MI 280824). Growth-temperature range for the. fungi was between 15° and 45°C. Aspergillus fu~igatus and Rhizomucor pusillus are t he r mot o Le ...
ABSTRACT Allozyme variation in protein encoded at 22 loci was studied in 9 cowpea accessions from three agroecological zones of Ghana (namely Deciduous forest, Guinea savannah and Sudan savannah) by electrophoresis. In addition, variation in thirteen morphological agronomic traits of the accessions were studied. The results indicated that: (i) 21 out of 22 loci were polymorphic (95.5%); (ii) cowpea accessions displayed average estimates of mean alleles per locus, A = 5.00; mean expected hete...
ABSTRACT Incidence of malaria in the Central Region of Ghana was investigated to determine age group and sex vulnerability as well as the parasite species distribution, haemoglobin status of patients and herbs used in treating the disease. Four Hospitals were used as study centers namely, Cape Coast District Hospital and the University of Cape Coast Hospital constituting the coastal zone; Saint Francis Xavier Hospital at Assin Foso and Our Lady of Grace Hospital at Breman Asikuma form...
ABSTRACT Black pod is a disease of Theobroma cacao L. and can cause up to 100% losses in crop yield. Breeding for resistance can reduce or prevent the incidence of the disease. This study was therefore designed to assess black pod disease resistance in 205 accessions of five populations; ‘T’ clones, progenies of ‘T’ clones, Amazonia, Series II hybrids and a control population of susceptible accessions by the leaf disc method and genetic fingerprinting using 13 mTcCIR microsatellite mo...
ABSTRACT Five Upper Amazons cocoa clones, namely NA33, PA150, PA7, SCA6 and SCA9 were selected for this study. The objective of the study was to ascertain the resistance level of the resistance to the CSSV disease. Test parents were clonally multiplied and inoculated and the expressed leaf symptoms studied. The difference observed in the parents were used to initiate hybridization. Mentor pollen technique was used to induce self-fertilization. Clonal multiplication was done by budding...
