Nanocomposite Packaging Delays Lignification of Flammulina Velutipes by Regulating Phenylpropanoid Pathway and Mitochondrial Reactive Oxygen Species Metabolisms
(Elsevier, 2020)Lignification is an important inducement of quality deterioration of postharvest Flammulina velutipes. In this study, phenylpropanoid pathway and mitochondrial reactive oxygen species (ROS) metabolisms were taken as ... -
Nanocomposite Packaging Regulate Respiration and Energy Metabolism in Flammulina velutipes.
(Elsevier, 2019)Energy metabolism is accompanied with postharvest senescence, deterioration and physiological disorder in Flammulina velutipes. In this study, nanocomposite packaging material (Nano-PM) inhibited rapid respiration thus ... -
Nanocomposite packaging regulates extracellular ATP and programed cell death in edible Mushroom (Flammulina velutipes)
(Elsevier, 2019)Our previous study indicated that nanocomposite packaging material (Nano-PM) containing nano-Ag, nano-TiO2, nano-SiO2 and nanoattapulgite alleviated postharvest senescence of Flammulina velutipes by regulating respiration ... -
Nitrogen fixation by common bean (Phaseolus vulgaris L.) in pure and mixed stands in semi-arid south-east Kenya
(Elsevier, 2001)Research was carried out in the field on the effect of intercropping common bean and maize crops in a semi-arid zone of south-east Kenya over two rainy seasons in 1997. The experimental design was a randomised complete ... -
Nodulation and nitrogen fixation in promiscuous and non promiscuous soybean (Glycine max (L.) Merrill) varieties in Eastern Kenya
(Kenya Society of Microbiology, 2010)Soil nitrogen deficiency is a major factor limiting soybean production. This problem can be alleviated by the use of nitrogen fertilizers which on the other hand adversely affect the environment, are expensive and ... -
Nutritional Diversity of Leafy Amaranth Species grown in Kenya
(Elewa Bio Science, 2014)Objectives: Despite the availability of many species of amaranth in Kenya, there is inadequate information on their nutritional diversity and how they can be best used in mitigation of malnutrition. Hence, this study was ... -
Oil Content and Fatty Acid Composition of Five Linseed Varieties Grown In Two Agro-Ecological Locations of Kenya
(Journal of Agriculture and Environmental Sciences, 2015)Linseed oil is rich in the health promoting fatty acids, alpha-linolenic acid (omega-3) and oleic acid (omega-9), and is increasingly being used as a nutraceutical. However, there is limited linseed production in Kenya ... -
Optical, microphysical and radiative properties of aerosols over a tropical rural site in Kenya, East Africa: Source identification, modification and aerosol type discrimination
(Pergamon, 2018)A better understanding of aerosol optical, microphysical and radiative properties is a crucial challenge for climate change studies. In the present study, column-integrated aerosol optical and radiative properties observed ... -
Partial Fertility Restoration as Affected by Night Temperature in a Season-dependent Male-sterile Mutant Tomato, Lycopersicon esculentum Mill.
(Journal of the Japanese Society for Horticultural Science, 2007-03-13)This study was conducted to investigate the influence of night temperature on the restoration of fertility in a season-dependent male-sterile tomato mutant (T-4). Plants were grown in greenhouses, in which minimum and ... -
Patterns of seed dispersal and establishment of the invader Prosopis juliflora in the upper floodplain of Tana River, Kenya
(African Journal of Range and Forage Science, 2011)Invasive species in Africa have important impacts on food security and biodiversity conservation. African floodplains in arid areas are critical wildlife habitats in addition to crop production and dry season livestock ... -
Pharmacology of DB844, an orally active aza analogue of pafuramidine, in a monkey model of second stage human African trypanosomiasis
(PLOS, 2012)Novel drugs to treat human African trypanosomiasis (HAT) are still urgently needed despite the recent addition of nifurtimox-eflornithine combination therapy (NECT) to WHO Model Lists of Essential Medicines against second ... -
Physicochemical and Antimicrobial Properties of Post-Synthesis Betanin and Chitosan Oligosaccharide functionalized Silver Nanoparticles
(Springer, 2020)Size uniformity and defined surface coating are important parameters for the biological properties of silver nanoparticles (AgNPs). Green synthesis uses biomolecules either in pure form or plant extracts as both reductants ... -
Physiological responses of composite tea to progressive drought.
(Tea Research Foundation of Kenya, 2013)An experiment was carried out on potted grafted tea in a greenhouse to quantify the effects of reducing soil moisture content on key physiological factors affecting growth, development, diurnal and physiological responses ... -
Plant regeneration via somatic embryogenesis of tropical maize (Zea mays L.) commercial hybrid lines.
(Journal of Tropical Microbiology and Biotechnology, 2008)Four commercial tropical maize genotypes (H627, H625, H513 and DLC1) were screened in vitro for callus initiation and plant regeneration from immature embryos. Callus was initiated on N6 medium supplemented with varying ... -
Plant Species Diversity and Composition of Two Wetlands in the Nairobi National Park, Kenya
(Asian Journal of Wetlands Ecology, 2012)Two wetlands (Hyena and Nalogomon) in the Nairobi National Park were investigated by comparing plant composition in and around their immediate vicinity. The most common aquatic plant species in the Hyena wetland was Cyperus ... -
Polyploidy Breeding of African Nightshade (Solanum section Solanum)
(International Journal of Plant Breeding, 2007)The perception of African nightshades (Solanum section Solanum) as “healthy” foods, supported by documentation of their high nutritional and medicinal benefits, has led to a sudden and steady upsurge in their consumption, ... -
Polysaccharides from Flammulina Velutipes Improved Scopolamine-Induced Impairment of Learning and Memory of Rats.
(Elsevier, 2015)Flammulina velutipes has been reported to be beneficial in learning and memory capabilities, but the mechanisms underlying this remain unclear. In this study, Morris water maze and biochemical analyses of rat brain were ... -
Population levels of indigenous bradyrhizobia nodulating promiscuous soybean in two Kenyan soils of the semi-arid and semi-humid agroecological zones
(Journal of Agriculture and Rural Development in the Tropics and Subtropics (JARTS), 2006)Soybeans grown in Africa have been selected to nodulate effectively with indigenous Bradyrhizobium spp. populations since Bradyrhizobium japonicum populations are considered absent or in very low numbers in African soils. ... -
