Costs analysis and toxicity of Jatropha curcas L. on maize weevil, Sitophilus zeamais Motsch

The toxicity of Jatropha seed oil to maize weevil, Sitophilus zeamais Motsch. in stored grains was tested in the laboratory. The cost analysis of seed oil extraction was estimated. The rates of seed oil treatment at 0.2, 0.5 and 1.0 ml and the untreated control for storage of 100 g grains were replicated four times. Each experimental unit contained five pairs of freshly emerged adult S. zeamais....

Production of exopolygalacturonase from wheat flour by Aspergillus awamori in submerged and surface culture fermentation

Pectinases are a group of hydrolytic enzymes that degrade pectic substances. They are produced by a variety of microorganisms including filamentous fungi. Studies were carried out on the production of exoplygalacturonase (Exo-PGase) using wheat flour by Aspergillus awamori in submerged fermentation (SmF) and surface culture fermentation (SCF). Higher titres of was observed when medium was supplements with...

Partitioning of exogenously supplied 14C substrates into primary metabolites and accumulation of total triterpenoids saponins in Centella asiatica

Comparative utilization of exogenously supplied carbon substrates as 14C-saccharose and 14C-acetate were analyzed for incorporation and accumulation into total triterpenoids saponins. Simultaneously, the metabolic status of the plant was determined by profiling assimilates into primary metabolic pool as sugars, amino acids and organic acids into shoots and roots of Centella asiatica. 14C-saccharose...

Comparative analysis of genomic DNA isolation procedures; hexa decyltrimethylammonium bromide (CTAB) and liquid detergent (morning fresh®) methods from Samsorg 41 (icsv 400)

Genomic DNA was prepared from germinating seeds of a variety of sorghum in Nigeria (Samsorg 41) using two different isolation protocols (CTAB and morning fresh® method). Highest quantity of DNA was obtained from Samsorg 41 using the morning fresh® method. Genomic DNA obtained using this method had a much lower purity as compared with that obtained using the CTAB method. Both methods produced genomic...

Ethnobotanical survey of the uses Annonaceae around mount Cameroon

An ethnobotanical survey was carried out in eight villages around Mount Cameroon in the South West Region of Cameroon. It was focused on determining the uses of the members of the family Annonaceae in this region. Show and Tell Semi-structured Interviews employing a checklist of questions and direct observations were used. The results obtained enable the presentation of the rate of utilization of the members of that...

Ecological behaviour and biogeography of endemic species of the genus Piper L. in Africa: A case of the Guineo-Congolean region

The aim of this study was to establish the ecology and the distribution patterns of the endemics Piper L. in the Guineo-Congolean region including the Lower Guinea, the Higher Guinea, the Congo Basin and the Mosaic of Lake Victoria. The distribution stretches from Senegal to Tanzania. Piper capensis and Piper guineense are both represented in Lower Guinea and Congo...

Effect of cassava/legumes intercrop before rice on weed dynamics and rice grain yield at Badeggi, Nigeria

A trial was carried out at the lowland experimental field of National Cereals Research Institute, Badeggi, Nigeria during the cropping seasons of 2005 and 2006 to determine the effect of preceding lowland rice with cassava/legume intercrop in the dry season on weed dynamics and rice grain yield.  The treatments consisted of FARO 52 rice variety cultivated after cassava ( IIT 427 and Bida local ) intercropped...

Effect of benzyladenine (BA) on fruit set and mineral nutrition of morula (Sclerocarya birrea subspecies caffra)

A field experiment was conducted to evaluate the effects of benzyladenine (BA) on fruit set and mineral nutrition of morula (Sclerocarya birrea subspecies caffra). Benzyladenine was applied when the fruitlets were 8 to 10 mm in diameter at concentrations of 0, 50, 100 or 150 mg/l. Application of BA to morula fruit trees significantly (p < 0.001) reduced fruit set of morula trees by between 48 to 67%. Morula...

A new strategy for complete identification of 69 grapevine cultivars using random amplified polymorphic DNA (RAPD) markers

DNA marker is a useful technique that has immense power in plant cultivar identification, which used to be the first preferential utility of any newly developed DNA marker technique. However, DNA markers have not been utilized well in the practice of plant identification, for which the bottleneck is no analysis methods available that can make the identification of plants with DNA marker easy, efficient and...

Thermal properties of Calamus deërratus, Raphia hookeri and synthetic board in building design in Southwestern Nigeria

For a self-cooling building, alternative sources of roofing and ceiling materials in building design was investigated. The thermal property of Rattan palms (Calamus deërratus), Raffia palms (Raphia hookeri) and synthetic Nigerite asbestos sheets were determined using the Lees’ disc apparatus. Results showed that Rattan palms sheet had the lower thermal conductivity (k = 0.046 Wm-1 K-1) and a...
