ABSTRACT

 

The effect of crude oil on growth and survival of Capsicum annuum was investigated in Ahmadu Bello University, Zaria. Planting was done in polythene bags measuring (60 x 25x 15cm) and each bag was filled with 15kg of top soil (0-15m depth) collected from Ologbo flow station, Benin City. Two polythene bags per crude oil concentration were replicated thrice in a randomized block design which made a total of 18 bags. Treatment of the soil was…

The efficient use of plant genetic resources requires the careful collection of germplasm, its conservation, evaluation, documentation and exchange. Over the last few decades, plant tissue culture has been used to propagate hundreds of plant species. The use of this technique has been particularly important for conservation and multiplication of plants that produce seeds, propagated vegetatively, recalcitrant or have unpredictable seed germination. In vitro collection is a natural outgrowth of this work. Tissue culture being a basic component of plant…

ABSTRACT

 

On-farm research is a set of procedures for adaptive research aimed at developing recommendations for representative groups of farmers. These groups of farmers’ plots are used as the research site, thereby allowing for appropriate site specific technology, valid results and faster adoption. The move towards on-farm research means that researchers, such as plant breeders and agronomists, who have been trained in techniques of on-station research, are now under pressure to move on-farm. As a result of variations between…

Corchorus (L) is an important vegetable, grown mainly for its leaves. It contributes to the dietary requirements of the local populace as well as local economy. Five accessions, three labeled NHCO3, NHCO25 and NHCO26 obtained from the Plant Genetic Resources Unit of Nigerian Institute of Horticulture (NIHORT), Ibadan and two BN/OD/01 and ON/OD/02 obtained from home gardens were evaluated for their proximate: ash, moisture, carbohydrate, protein, lipid and fibre contents. Result showed that all biochemical parameters evaluated vary significantly (P0.05)…

Abstract

The study investigated the exogenous application of Naphthalene acetic acid (NAA) on the vegetative traits of two varieties of pepper (Capsicum annuum L. and Capsicum frutescens L.) the treatment were 0, 1, 5, 10 and 20 ppm NAA. NAA at 1ppm concentration increased plant height, leaf area and number of leaves in both varieties.

Abstract

Folic acids are essential cofactors for synthesis of DNA, RNA, membrane lipids, methionine metabolism and neurotransmitter synthesis. P. falciparum is capable of synthesizing folate de novo or obtaining it through salvage, whereas humans can only obtain folate from their diet, making the folate pathway products important targets for chemotherapy. Although…

ABSTRACT

BACKGROUND:

Inappropriate arginine vasopressin (AVP) secretion has been reported in schizophrenic patients. However, there is lack of information on serum level of copeptin and its diagnostic performance in schizophrenia. This study therefore, evaluated serum copeptin and its diagnostic performance in schizophrenic patients.

METHODS:

reactive  metabolites  and  not  by  the  parent  compound.  The  antihepatotoxic  efficacy  of  ethanolic  leaf  extract  of Vernonia
amygdalina against DMN-induced liver damage in rats thus, needs to be investigated.  
Methodology: Rats were given DMN, at a single dose of 12 g/kg body weight orally on day 8 after pretreatment with 400mg/kg
Vernonia amygdalina for 7days and…
