Synthesis of silver nanoparticles using crude leaf extracts of Acacia nilotica, Azadirachta indica, Carissa spinarum, Melia azedarach, Senna didymobotrya and Warburgia ugandensis, and their antifungal activity against Sporisorium scitamineum
Bio-synthesised silver nanoparticles are effective in controlling several micro-organisms. They are correspondingly environmentally friendly, affordable, and easy to synthesise when compared with chemically synthesised silver nanoparticles. This study investigated the efficacy of biosynthesized silver nanoparticles against the fungus Sporisorium scitamineum, the causal agent of sugarcane smut. The reduction of silver...
Fatty acid profiles in Chinese Maiwa yak milk across the lactation cycle
An experiment was conducted to determine fatty acid (FA) pro?les in Chinese Maiwa yak milk across the lactation cycle. Sixty-one healthy, similar weight, 4-7 years old, 3-6 parity Maiwa yaks with unrelated background were selected randomly from Hongyuan County, Sichuan province, in southwest of China (with the altitude over 3500 m). The yaks graze on natural pasture all year around without irrigation, fertilizer, or...
Analgesic and anti-inflammatory activities of propolis obtained from Gboko, Nigeria
The use of propolis for the treatment of various ailments in which inflammation and pain is involved is cross-cultural. This report was designed to investigate the analgesic and anti-inflammatory activities of propolis obtained from Gboko, Benue State using hexane, ethyl acetate, and ethanol solvents. Propolis sample obtained from beehives was homogenized, extracted and dried at 40°C. The dry extract was prepared in...
Effect of different concentrations of plant growth hormones on callus induction and regeneration of Shea tree (Vitellaria paradoxa)
The slow natural regeneration pattern of the Shea tree due to the long gestation period and intense harvest has limited the domestication and genetic improvement of this tree. These limitations have necessitated the need for an alternative method of conserving the Shea tree outside the natural habitat. The propagation of the Shea tree by the in-vitro clonal technique presents such an alternative method. The purpose of...
Influence of arbuscular mycorrhizal fungi and phosphorous on the growth, nutrient uptake, chlorophyll content and some metabolites of eggplant (Solanum melongena L. VAR. Yalo) under saline conditions
The effects of arbuscular mycorrhizal fungi (AMF) and phosphorous (P) on the growth, nutrient uptake, chlorophyll content and some metabolites of eggplant (Solanum melongena L. VAR. Yalo) were determined under saline conditions, through a greenhouse experiment conducted for six weeks. Seedlings were planted in polythene bags previously filled with sand, 1 g of P and 50 g of AMF for all concentrations (0, 50,...
