Investigating the potential of Aucoumea klaineana Pierre sapwood and heartwood wastes to produce cellulosic ethanol

This work investigates for the first time the different reactivity exhibited by sapwood and heartwood wastes under two conditions: They were pretreated with catalyzed ethanol organosolv in the presence of sulfuric acid and their pulps underwent enzymatic hydrolysis by Trichoderma reesei which causes them to release neutral sugars for the production of cellulosic ethanol.  Aucoumea klaineana Pierre (Okoumé)...

Comparison of seed priming techniques with regards to germination and growth of watermelon seedlings in laboratory condition

Seeds of watermelon [Citrullus lanatus (Thunb.) Matsum and Nakai, cv. Crimson Sweet] were used to investigate the effects of different priming techniques on seed germination and early seedling growth. The seeds were soaked in solutions of 0.2% gibberellin (50 mg L–1 gibberellic acid), 0.2% cytokinin (90 mg L–1 kinetin), 0.2% potassium nitrate (2 g L–1 KNO3), 0.2% calcium nitrate [2 g L–1...

Linkage disequilibrium and association mapping of drought tolerance in cotton (Gossypium hirsutum L.) germplasm population from diverse regions of Pakistan

Drought stress is a major abiotic stress that limits crop production. Molecular association mapping techniques through linkage disequilibrium (LD) can be effectively used to tag genomic regions involved in drought stress tolerance. With the association mapping approach, 90 genotypes of cotton Gossypium hirsutum, from diverse regions of Pakistan were used. The morpho-physiological traits of all genotypes were evaluated...

Inbreeding depression in crosses of coerulea clones of Walker’s Cattleya (Cattleya walkeriana Gardner)

Orchids are among the most beautiful flowers and endangered due to habitat destruction and over-collection. Cattleya walkeriana is one of the most beautiful flowers joining the small sized plant with medium large and heavily scented flowers. It is widely known and appreciated by its beautiful clones and it has much to offer to breeders because their plants have besides other attributes as small habit and big flowers,...

The protective role of honey against cytotoxicity of cadmium chloride in mice

The present study aimed to investigate the honey (HY) protective role in opposition to cadmium (Cd) induced chromosomal aberrations of bone marrow and sperm abnormalities. Forty five (45) adult male albino mice were caged into six groups. Mice were injected, i.p, 300 mg HY/kg and/or 0.67 mg CdCl2/kg b.w for 96 h, separately and alternated. The alternated trials were continued for consecutive eight days. Results show...

Shelf life improvement of sorghum beer (pito) through the addition of Moringa oleifera and pasteurization

Pito is a traditional alcoholic beverage that is mostly brewed in the three northern regions of Ghana. Although widely consumed and used in many festivities, poor storability limits its economic potential as an income-generating venture for most women. This study was carried out to improve the shelf-life of pito through the addition of Moringa oleifera leaf extract and pasteurization (75 to 80°C). Microbial...
