Genetic diversity of pumpkin accessions in Kenya revealed using morphological characters, diversity index, CATPCA and factor analysis
(2018-02)Pumpkin is one of the most morphologically variable genera in the entire plant kingdom. In Kenya, its genetic diversity is undocumented and distribution is haphazard. An expedition was done in Kakamega and Nyeri regions ... -
Genetic variation of growth dynamics in maize (Zea mays L.) revealed through automated non-invasive phenotyping.
(John Wiley & Sons Ltd, 2017)Hitherto, most quantitative trait loci of maize growth and biomass yield have been identified for a single time point, usually the final harvest stage. Through this approach cumulative effects are detected, without considering ... -
Genome-Wide Identification of GASA Gene Family in Ten Cucurbitaceae Species and Expression Analysis in Cucumber
(MDPI, 2022)Gibberellic acid-stimulated in Arabidopsis (GASA), a unique small molecular protein of plants, plays an essential role in plant growth and development. The GASA family genes have been identified and studied in many plants. ... -
Genome-Wide Identification of the B-Box Gene Family and Expression Analysis Suggests Their Potential Role in Photoperiod-Mediated β-Carotene Accumulation in the Endocarp of Cucumber (Cucumis sativus L.) Fruit
(MDPI, 2022)Carotenoids are indispensable to plants and essential for human nutrition and health. Carotenoid contents are strongly influenced by light through light-responsive genes such as B-Box (BBX) genes. BBX proteins, a class ... -
Genome-Wide Identification, Phylogenetic and Expression Pattern Analysis of GATA Family Genes in Cucumber (Cucumis sativus L.)
(MDPI, 2021)GATA transcription factors are a class of transcriptional regulatory proteins that contain a characteristic type-IV zinc finger DNA-binding domain, which play important roles in plant growth and development. The GATA ... -
Geochemical and Mineralogical Characteristics of Geophagic Materials from Kiambu, Kenya
(2012)Geophagia is the deliberate consumption of soil and clay. The practice of geophagia is due to reasons of culture, medicinal, religious and mineral deficiency. Geophagy is widespread among pregnant and ... -
Geochemical and Mineralogical Characteristics of Geophagic Materials from Kiambu, Kenya
(Modern Scientific Press Company, Florida, USA, 2012-09)Geophagia is the deliberate consumption of soil and clay. The practice of geophagia is due to reasons of culture, medicinal, religious and mineral deficiency. Geophagy is widespread among pregnant and ... -
Geophysical structure of Homa Hills Geothermal field based on Gravity and magnetic survey
(2011)Gravity and ground magnetic surveys were conducted over an area of 76 Km 2 in order to investigate thermal structures responsible for geothermal manifestations such as hot springs in the Homa Hills geothermal prospect. The ... -
Grazing Behaviour of Saanen and Toggenburg Goats in Sub-Humid Tropical Conditions of Kenya
(2001-03-22)The behavior of 6 Toggenburg and 6 Saanen female goats, grazing on natural vegetation in a modified sub-humid tropical environment of Kenya, was studied during the dry (January and February) and wet (April and May) seasons ... -
Ground water prospecting using Self Potential (SP) in Mungoni area of TharakaNithi, Kenya
(2018)Self-potential method is based on the surface measurement of natural potential resulting from electrochemical reactions in the subsurface. It does not require electric currents to be injected into the ground as in the ... -
Growth of ranunculus cutflower under tropical high altitude conditions.
(Horticultural Association of Kenya, 2009)Cutflower production and marketing is partly challenged by lack of new, exciting and improved varieties to satisfy customer needs of a different flower. Ranunculus (Ranunculus asiaticus L.) is a bulbous plant that originated ... -
Growth of ranunculus cutflower under tropical high altitude conditions. 2: Effects of GA3 and shade on light intensity and temperature modification
(Horticultural Association of Kenya, 2009)Customer needs of a different flower are increasing over time worldwide. Many bulbous plants including ranunculus fit the category of a different flower because they are not known. Ranunculus(Ranunculus ... -
