Identification of QTL for Striga hermonthica Resistance Using Backcross Population Derived from a Cross between Oryza sativa (cv. Nipponbare) and O. rufipogon
(Canadian Center of Science and Education, 2015-02-01)
The obligate root hemiparasite, Striga hermonthica (Del.) Benth., native to sub-Saharan Africa causes serious
economic constraint to cereal production. Studies on Striga spp. interactions with rice are desirable as it is ...
Allelopathic potential of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis l.)
(2015)
Allelopathy is a common among plants. Allelopathic substances affect seed
germination, plant growth and development or even affect chlorophyll
synthesis by the plant leaves. Tithonia diversifolia contains allelochemicals
that ...
Allelopathic potential of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis l.)
(2015)
Invasive plant species when introduced into new environments may result into a number of
ecological problems (Howard et al., 2000). They may influence other species through
pathways such as allelopathy or phytotoxicity ...
Growth changes of seven Amaranthus (spp) during the vegetative and reproductive stages of development as influenced by variations in soil water deficit
(International Journal of Research and Innovations in Earth Science, 2015)
Soil water deficit is a principal a biotic factor that limits plant growth and development in dry areas. Insufficient moisture contributes to soil water deficit and some negative effects on Amaranthus (spp) such as reduced ...
Patterns of CO2 exchange and productivity of the herbaceous vegetation and trees in a humid savanna in western Kenya
(Springer Science+ Business Media Dordrecht, 2015)
Factors governing the dynamics between woody and herbaceous vegetation in the savanna are of ecological interest since they determine ecosystem productivity and stability. Field measurements were conducted in a humid savanna ...
Chlorophyll fluorescence parameters and photosynthetic pigments of four Glycine max varieties under Aluminium chloride stress
(PSCI Publications, 2015)
Soil acidity limits agricultural production globally. Different kinds of
stresses, mainly Al stress, generated from acid soils affect plant growth and
result in food shortage and production. General effects of Al toxicity ...
Ecology and Physiology of Plant growth in relation to soil salinity
(2015)
This work is intended as a review of soil salinity as one common abiotic
stress in ecological systems that adversely affect plant growth. In arid and
semi arid areas, saline areas or areas irrigated with saline waters, ...
Evaluation of different improved upland rice varieties for low soil nitrogen adaptability
(IJPSS, 2015)
Scarcity of nitrogen fertilizer is a major constraint to rice production particularly in developing
countries. Low soil fertility prevalent in farmer’s fields has led to low rice yields and the ever
escalating fertilizer ...

A critical review of the role of taro Colocasia esculenta L.(Schott) to food security: A comparative analysis of Kenya and Pacific Island taro germplasm
(PSCI Publisher, 2015)
The many threats to global food security in Sub Sahara Africa include poverty, unsustainable cultivation practices and climate change. Increasing poverty and decreasing food security have been exacerbated by continued low ...
