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...

ABSTRACT Fruit of Capsicum are among the most consumed spices throughout the world and are very important commercially. Plant bioactive compounds are increasingly gaining more attention because of their effectiveness in improving human health and nutrition. The sturdy was aimed at determining the phytochemical, mineral, and nutritional compositions of some selected Capsicum spp fruit. The study was conducted due to lack of information on chemical compositions of the selected fruit in Gombe. ...
ABSTRACT The experiment was carried out to investigate the effect of cement dust pollution onAmaranthus viridis in respect to growth, heavy metal uptake and the plant in general. Loamysoil was polluted with Dangote cement in a ratio of (100:1). It was observed that the presenceof cement dust in the polluted soil did not affect the germination time of the plant. Upongrowing the Amaranthus plant were polluted with 10.2gcement dust at 3datys in...
This work was written to help people and the society in general understand the contributions little, unnoticeable things like the pollen grains make in the world and also for them to see the relevance of paleo-botany
This study focused on elucidating the anatomy of Moringa oleifera seed and developing an efficient and cost effective procedure for using Moringa oleifera seeds to produce natural coagulant for use in drinking water treatment. The study investigates processing Moringa oleifera seeds to concentrate the bio-active constituents which have coagulation activity. It is generally accepted that Moringa works as a coagulant due to positively charged, water-soluble proteins, which bind with negatively ...
The effect of different treatments of breaking seed dormancy of Parkia biglobosa seeds were studied in this project work. The results of different treatments observed showed 88% for concentrated H2SO4, 80% for scarification (with scalpel) and 52% for dry heat while the untreated seed (control) is 40% germination. The speed of germination for some treated seeds are also observed to be greater than that of the untreated seeds with seeds treated with concentrated H2SO4 having the highest value o...
Vegetation-environment (soil) was studied in fallow plots in Uyo, ranging from 0-year-old to 6-year-old. Systematicsampling method was used to sample both vegetation and soil. The parameters determined for vegetation included; Height,Frequency, Basal area and Crown cover for all species. The soil physical and chemical properties were also determined.Results obtained showed that there were eight (8) plant species in the 0-year old plot, 12 species in the 2-year old plot,20 species of plants in...
ABSTRACT An experiment was conducted during the 2011/2011 cropping season at Plant Science and Biotechnology Laboratory, Department of Biological Sciences, Nasarawa State University, Keffi, to study the callus induction of garlic (Allium sativum L.) at various combinations and concentrations of growth regulators and also to develop an efficient protocol for callus induction of garlic via economically viable explants of indigenous garlic accessions. Garlic cloves used as explants, were col...
