Core Ideas A HYDRUS module was implemented to model root growth as a function of environmental stresses. Simulations were compared with experimental data for temperature stress effects on growth. Temperature‐dependent parameters fitted using DREAM. sensitivity analysis revealed key the modeling approach. adapted and into software packages different The assumes that various factors, well soil hydraulic properties, can influence development under suboptimal conditions. implementation functions...
Two bell pepper (Capsicum annuum) cultivars, differing in their response to chilling, were exposed three levels of root-zone temperatures. Gas exchange, shoot and root phenology, the pattern change central metabolites secondary caffeate benzoate leaves roots profiled. Low temperature significantly inhibited gaseous with a greater effect on sensitive commercial hybrid (Canon) than new bred enhance abiotic stress tolerance (S103). The latter was less affected by treatment respect plant height,...
Baobab is a priority pan-African tree species that can be put on similar pedestal as cocoa. The wild and indigenous baobab has the potential for importance in tropical agriculture exotic commodity crop cocoa, whose beans are exported international chocolate industry. Considering advantages associated with cultivation, could one of cash crops cultivated West Africa. Domestication cultivation plant will improve biodiversity which drive many livelihoods important strategies solving food...
Green roofs in the Mediterranean region are often exposed to high levels of radiation, extreme temperatures, and an inconsistent water supply. To withstand these harsh conditions shallow soils poorly aerated growth media, plants must be armored with adaptations. Strategies that have evolved desert can play significant roles use for green covers. In following, we will specifically focus on (1) heat (2) drought, (3) salinity. Further, discuss (4) interactions between neighboring plants....
Core Ideas Shoot and root interactions under extreme temperatures contributed to tolerance. Impact of dynamics on soil pore water EC Cl uptake increased temperatures. Tolerance assimilation allocation C N organ growth. Fluctuations winter summer day night strongly influence shoot growth, as well the whole plant tolerance We compared response a commercial pepper ( Capsicum annuum L.) hybrid (Romance, Rijk Zwaan) range when grafted new rootstock (S101, Syngenta), self‐grafted, or ungrafted....
Low temperature is a prominent limiting factor for tropical originated crops production in temperate regions, particularly during cool-season production. The diverse response of two rootstocks (Canon-sensitive and S103-tolerant to low root-zone temperature) was studied when exposed aeroponically different regimes at the root zone: constant 14°C (LRZT), transient exposure LRZT 27–14−27°C control 27°C. Gas exchange, shoot dry mass, morphology were measured. Shifts central secondary metabolite...
Using gas chromatography—electron capture detector protocol, pesticide residue levels on four common vegetables (cabbage, carrot, lettuce, and tomatoes) consumed in Ho Municipal, Ghana, were investigated. A total of 5 kg each the randomly sampled triplicate from three different markets. Organochlorine pesticides, including residues γ-HCH, δ-HCH, heptachlor, aldrin, p, p'-DDT, o, p'-DDT p'-DDE detected above recommended EU MRL. Lettuce recorded highest aldrin (1.23 mg/kg) as well γ-HCH (0.013...
Crop models are useful tools for simulating the impact of climate change on crop growth, development and yield. This study assesses cowpea yield in soils with low levels phosphorous content mainly Sudan Savanna Forest Transition Zone West Africa. A model solution within general modelling framework SIMPLACE combination output four 3 contrasting shared socio-economic scenarios (SSP126, SSP370, SSP585) was used to simulate climatic phenology, above ground biomass parameters cowpea. The...
Abstract The study of transpiration, water, and nutrient uptake during abiotic stress in the root zone is hindered because hidden nature zone. In this study, a modified aeroponic system was used to evaluate whole plant nitrate water growth development tomato plants response salinity. Tomato seedlings were exposed three levels salinity (1.5, 4.5, 9 dSm −1 ) (1, 4, 8 mM NO 3 separate experiments conducted concurrently. Whole estimated. Our revealed that ~30 35 days after treatment (DAT), rate...
The objective of this study is to identify cowpea genotypes that are tolerant both phosphorous and drought stresses on highly weathered soil. It hypothesized (1) have the highest grain yield under optimum conditions do not perform best P or water stress (2) also well combined stress. An experiment was conducted in humid forest zone Ghana during two dry seasons (2017 2018). Ten were evaluated response four combinations fertilizer treatments. treatments included 0 kg ha−1 + (0P WS; control...
A total of fifteen best seed-derived cocoa varieties known for their high combining abilities vigour and yield were evaluated at the vegetative stage between 29 to 39 months after planting. Environmental factors, physiology, growth, carbohydrate, carbon, nitrogen metabolism resilience in response field stress conditions during wet dry main growing seasons evaluated. The plants then subjected environmental (high temperature, low rainfall, soil moisture content) season as conditions, compared...
Grain legumes are essential for the protein supply to an ever-growing population in Africa. However, little is known about adaptational potential and thus resilience abiotic stress of major grain under future climatic change evaluation climate impact adaptation. This study assessed adaptation some cowpea genotypes moist (Kumasi—Ghana) dry savanna (Ouagadougou—Burkina Faso) biomes West Africa based on a validated process-based SIMPLACE model using output four global circulation models (GCMs)...
