TL;DR: The use of cuttings with 25–35 cm2 leaf area and treatment with 1% (w/w) IBA powder is recommended for vegetative propagation of X. aethiopica through stem cutting.
Abstract: The amenability of Xylopia aethiopica to vegetative propagation was assessed. Twelve auxin treatments and three ranges of leaf area were investigated for their effects on the propagation of...

TL;DR: Eggsi kernels were highly infected with postharvest fungi especially Aspergillus species and Piper guineense, Xylopia aethiopica and Ocimum gratissimum could be used as a safe management option to mitigate storage fungi contamination in Egusi kernels.
Abstract: Melon (Citrullus colocynthis L) is an important crop used mainly for soups in Nigeria Egusi: as it is commonly called in Nigeria is contaminated by many fungal pathogens which reduce quality of seeds during storage Use of botanicals can be a safe method to manage fungal contamination instead of chemicals which pose a threat to human health Therefore, efficacy of Piper guineense, Xylopia aethiopica and Ocimum gratissimum on fungi in shelled Egusi seed kernels (EK) were evaluated One market in each of six South-western Nigerian states where Egusi is sold was purposively selected in 2012 and 2013 Egusi kernels (1⁄2kg, n = 162) were purchased from selected traders for fungi isolation, identification and incidence (%) determination Clean EK treated with botanical powder (10, 20 and 40 g kg–1) were inoculated with Aspergillus flavus, A niger, A tamarii, Rhizopus sp, Penicillium aurantiogriseum, P citrinum and Fusarium solani bi-weekly for 14-week storage period to evaluate growth reduction (%) Control was inoculated with sterile distilled water Aspergillus flavus, A niger, A tamarii, Penicillium citrinum, P aurantiogriseum, Fusarium solani and Rhizopus sp were frequently encountered in EK Aspergillus (324±16%) was the most predominant fungus followed by Rhizopus (215±20%) in all States Piper guineense (40 g kg–1), X aethiopica (20 g kg–1) and O gratissimum (10 g kg–1) powders significantly reduced aflatoxin contamination by 425%, 565% and 450%, respectively; fungi growths were progressively reduced by P guineense (55-900%), X aethiopica (67-1000%) and O gratissimum (74 667%) up to 12 weeks of storage Egusi kernels were highly infected with postharvest fungi especially Aspergillus species Xylopia aethiopica at 20 g kg–1, O gratissimum (400%) and P guineense (400%) reduced fungi growth on Egusi considerably and therefore could be used as a safe management option to mitigate storage fungi contamination in Egusi kernels

TL;DR: Toxicity of Xylopia aethiopica on Culex p.
Abstract: The hexanolic extract ofXylopia aethiopica (Ethiopean pepper) was tested for acute toxicity on the larva of Culex p. quiquefasciatus reared in the laboratory of the Department of Biological Sciences University of Agriculture Abeokuta, Nigeria. Five concentrations: (5Oppm, lOOppm, 2000ppm, 300ppm and 400ppm) were evaluated for acute toxicity on the larvae and total percentage mortalities recorded at intervals of I, 12,24,48 and 96 hours in each test. Effects of sunlight and ultra violet radiation on stability of the extract's potency at 2,4, and 8 hours respectively were equally examined. The mean lethal concentration LC50 was 257ppm. Toxicity of Xylopia aethiopica on Culex p. quiquefasciatus larvae was gradual and persisted throughout the test period. Sunlight exposure has no significant effect on the potency of Xylopia oil while ultra-violet radiation activated the larvicidal properties.

TL;DR: The effect of oven, solar and sun drying methods on the mineral properties of the Ethiopian Pepper was determined by conducting a study at the Department of Horticulture, Kwame Nkrumah University of Science and Technology (KNUST) using a Completely Randomized Design (CRD).
Abstract: The effect of oven, solar and sun drying methods on the mineral properties of the Ethiopian Pepper was determined by conducting a study at the Department of Horticulture, Kwame Nkrumah University of Science and Technology (KNUST) using a Completely Randomized Design (CRD). The mineral properties analyzed were, calcium, iron, magnesium, sodium, and zinc. Solar dried Ethiopian pepper, had significantly higher (p ≤ 0.01) calcium (0.38%) as compared to that of oven and sun-dried Ethiopian pepper. Iron level (68 mg/kg) was relatively highest in solar dried Ethiopian pepper whiles magnesium content was highest in oven dried Ethiopian pepper (0.25%). Sodium (1.50%), and zinc (41.75 mg/kg) were recorded for oven dried Ethiopian pepper. Ethiopian pepper dried under oven and solar drying methods retained higher levels minerals.
