Host-plant acceptance, fecundity and longevity of tetranychus evansi (acari: tetranychidae) on selected tomato accessions
(Global Science Books, 2009-01-21)
Solanum villosum is an important leafy vegetable in Kenya whose production faces low yields. Two potentially high leaf-yielding
genotypes of S. villosum, T-5 and an octoploid have been developed. Field experiments were ...
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) ...
Effect of pH and magnesium on colour development and anthocyanin accumulation in tuberose florets
(African Crop Science Conference Proceedings, Vol. 9. pp. 227 - 234, 2009)
Anthocyanins are a group of plant pigments responsible for colors ranging from red to violet and blue. Anthocyanins are
pigments that accumulate in the vacuoles of plant epidermal cells. Chroma and hue are dependent on ...
Intermittent presumptive treatment of malaria to prevent low birth weight in newborns in a cohort of pregnant women from a malaria endemic area.
(AJOL, 2009)
Objective: To determine and describe the patterns of low birth weight in newborns of a cohort of mothers given intermittent presumptive treatment (IPT) for malaria prevention in a malaria endemic area of Kenya.
Design: A ...
Transpirational water use and its regulation in the mountainous terrain of S. Korea
(American Geophysical Union, 2009)
Quantifying water use by forests growing on complex mountainous terrain is difficult and understanding of controls on water use by these forests a challenge. Yet mountains are crucial as water towers and better understanding ...
A comparison of CO2 fluxes via eddy covariance measurements with model predictions in a dominant subtropical forest ecosystem
(Copernicus Publications, 2009)
CO2 fluxes were measured continuously for twelve months (2003) using eddy covariance technique at canopy layer in a dominant subtropical forest in South China. Our results showed that daytime maximum CO2 fluxes of the whole ...
Responses of CO2 exchange and primary production of the ecosystem components to environmental changes in a mountain peatland
(Springer Science+Business Media, 2009)
The complexity of natural ecological systems presents challenges for predicting the impact of global environmental changes on ecosystem structure and function. Grouping of plants into functional types, that is, groups of ...
Overcoming the Challenges of Estimating Water Use in Temperate, Mixed Deciduous Forest of S. Korea
(American Geophysical Union, 2009)
About 80% of forests in Korea occur in mountainous regions and are composed of a rich diversity of mixed deciduous tree species. Mountains in this region receive more rainfall and act as fountains that supply fresh water ...
Teacher self-perceptions of effectiveness: a study in a District of Kenya
(Taylor and Francis, 2009-03)
Background and purpose: The paper reports a study of the perceptions of teachers in secondary schools in the Gucha district of Kenya of their own effectiveness, the structure of their self-perceptions, variations in ...
Review of public forestry administrations and related institutions in Sub-Saharan Africa
(Discov. Innov, 2009)
The main findings of a study on forest administration and related institutional arrangements (PFA) are highlighted. The relevance and changing roles of PFA in Sub-Saharan African (SSA) countries are covered in the context ...
