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...
