Host-plant acceptance, fecundity and longevity of tetranychus evansi (acari: tetranychidae) on selected tomato accessions
(Afr. J. Hort. Sci., 2009)
Seven tomato (Lycopersicon sp.) accessions were evaluated for their resistance to the tomato red spider mite, Tetranychus evansi Baker and Pritchard, in the laboratory. Data recorded was: (i) trichome density and (ii) ...
Effects of day-length and temperature on floral structure and fertility restoration in a season-dependent male-sterile Solanum villosum Mill. mutant
(Springer Verlag, 2007)
Solanum villosum is an important African leafy vegetable whose yield is limited mainly by competition from early and excess fruit-set. Induced male-sterility is a potential tool to reduce this competition and enhance yields. ...
Exploiting the Genetic Diversity of Vegetable African Nightshades
(Global Science Books, 2013)
frican nightshades (
Solanum
section
Solanum
) are an important source of daily nutrients and income for small-scale farmers in sub-
Saharan Africa and are a delicacy for urban inhabitants. The section ...
High fluoride water in Bondo-Rarieda area of Siaya County, Kenya: a hydro-geological implication on public health in the Lake Victoria basin
(BMC Public Health, 2014)
Background: Only a few studies to evaluate groundwater fluoride in Eastern Africa have been undertaken outsidethe volcanic belt of the Great Eastern Africa Rift Valley. The extent and impact of water fluoride outside ...
Mutation Breeding of African Nightshade ( Solanum section Solanum )
(Global Science Books, 2007-04-12)
African nightshades (
Solanum nigrum-
related species) are some
of the most widely consumed traditional
leafy herbs and vegetables, particularly in Africa and South-East Asia. The leaves contain high levels of ...
Floral Genetics of African Nightshade (Solanum section Solanum)
(International Journal of Plant Developmental Biology, 2007)
Solanum section Solanum, centering on the species commonly known as African nightshade, and botanically known as the “Solanum
nigrum complex” is composed of a large number of morphogenetically distinct taxa, with certain ...
Response of leaf yield and nutritive value of african nightshade (solanum villosum) genotypes to nitrogen application
(African Journal of Horticultural Science, 2010)
The wild-type Solanumu villosum is an important leafy vegetable in Kenya, which however is low-yielding mainly due to the early flowering and prolific fruiting. Two new genotypes of S. villosum, T-5 and octoploid with ...
Assessment of tolerance to salt stress in Kenyan tomato germplasm
(International Journal of Plant Breeding, 1997)
Tomato is an important vegetable crop in Kenya and the development of salt tolerant cultivars would enhance its productivity in the vast marginal areas of the country. This study was aimed at determining the magnitude of ...
Induced male-sterility alters dry matter distribution in solanum villosum mill.
(ISHS, 2008)
African nightshades are leafy vegetables popular in Africa and South-East Asia for their high nutritional and medicinal value. The plants are strongly autogamic, exhibiting early and excessive flowering coupled with prolific ...
Scope for genetic enhancement of the parasitisation potential of four native strains of Trichogrammatoidea sp. nr. lutea Girault (Hymenoptera: Trichogrammatidae) in Kenya
(Taylor & Francis, 2007-09-14)
In response to emerging interest in commercial mass production of Trichogramma for Helicoverpa armigera biocontrol in eastern Africa, laboratory experiments were undertaken to assess the scope for genetic enhancement of ...
