(University of Embu, 2019)Crotalaria brievidens and Crotalaria ochroleuca are horticultural crops that are largely consumed in western parts of Kenya and other parts of the country. However, this plant, a part from its use as a source of food by ... -
Phytoplankton Composition, Growth Rates and Oil Production Potential of Fast Growing Species from Lake Naivasha and Water Reservoirs at Embu University College
(University of Embu, 2017-01)The demand for non-renewable fossil fuel has greatly increased in the last few years from 84 million barrels of fossil fuel per day in 1980’s to over 100 million barrels per day in 1990. To supplement this demand, research ... -
Phytoplankton Species Evenness along a Gradient of Connected Ponds at the University of Embu
(University of Embu, 2019)Phytoplankton form an important part of food webs in aquatic ecosystems. Their abundance is influenced by physical and chemical water properties. The water reservoirs at the University of Embu have proven an important ... -
Picocystis salinarum (Chlorophyta) in saline lakes and hot springs of East Africa.
(2012-01)The occurrence of Picocystis salinarum in saline inland waters of East Africa was investigated using a polyphasic approach of small-subunit (SSU) rDNA phylogeny and light microscope observations. Recent studies have found ... -

Plant breeding for organic agriculture: something new?
(BioMed Central, 2015)The role of both organic (OF) and conventional (CF) farming remains open to debate particularly when related to food security and climate change. Targeting plant breeding for OF can contribute to reduce its yield gaps ... -
Plant Cell Wall, a Challenge for Its Characterisation
(Scientific Research Publishing, 2016-06)The plant cell wall is a complex 3D network composed of polysaccharides, lignin and proteins. The knowledge of the structure and content of each cell wall polymer is a prerequisite to understand their functions during plant ... -
Plant Hybridization as an Alternative Technique in Plant Breeding Improvement
(2019-05)For ages, plant breeders have relied on the genetic variability that results from sexually crossing plants within the same species. However, the variability that exists within species populations is inadequate, hence the ... -
