A Review Of Opportunities And Challenges In Conservation And Use Of Medicinal And Aromatic Plants in Nigeria.

Nature deposited in Nigeria several beneficial plant materials especially medicinal and aromatic plants (MAPs) for the treatment of ailments through herbal preparations, and for other culinary, traditional, medical and pharmaceutical uses. Preparation of natural medicine and production of herbal remedies by use of MAPs have proved to be a great alternative to the substandard production, cost and inaccessibility of synthetic orthodox medicines to rural dwellers. Despite the opportunities, ther...

Assessment of regeneration potential of Hibiscus sabdariffa L. under established ecosystems in Cameroon

Hibiscus sabdariffa is a non-timber-forest-plant (NTFP) that has the potential of producing fibers good in paper-making. Germination and growth potentials of H. sabdariffa under farmland, fallowland, plantation and forest ecosystems were studied. Seeds of H. sabdariffa were sown to assess germination percentage, germination rate, germination time and velocity coefficient on established plots of each ecosystem. Seedlings were randomly selected to measure growth and yield pa...

Biological Control Using Trichoderma harzianum against Penicillium purpurogenum, Causal Agent of White Yam Tuber (Dioscorea rotundata Poir) Rb

In vitro assessment of biological control of Trichoderma harzianum against Penicillium purpurogenum isolated from rotted yam tubers (Dioscorea rotundata Poir) in storage was conducted in the Advanced Plant Pathology Laboratory, Federal University of Agriculture, Makurdi, Nigeria. The antagonist and the pathogen were paired in dual culture at different times (antagonist same time with the pathogen, 2 days before the inoculation of the pathogen and 2 days after the inoculati...

Influence of Pedological Regimes on Plants Distribution in a Lacustrine Wetland in Uyo, Akwa Ibom State, Nigeria.

 Studies on the influence of pedological regimes on plant distribution in a lacustrine wetland in Uyo, Akwa Ibom State, Nigeria revealed variations in density and frequency of plant species as a function of the soil parameters. A quadrat size of 5m x 5m through systematic sampling was used to sample the vegetation spaced at regular intervals. The vegetation parameters determined were density and frequency. Soil samples were collected at different depths (0 – 15 cm and 15 – 30 cm) and ana...
