Hydrological consequences of two native shrubs in semi-arid Senegal : patterns, processes, concepts and methods

Creator:: Kizito, Fred
Abstract:: Water availability is a critical limiting element in semi-arid ecosystem productivity and presents particular challenges in Sahelian countries such as Senegal. The landscapes are characterized by the presence of two common semi-arid shrubs (Piliostigma reticulatum and Guiera senegalensis), both of which may be important hydraulic regulators in these water-limited ecosystems....
Resource Type:: Dissertation
Full Text:: requires knowledge of root 5 distribution and plant consumptive water use patterns (Ong et al., 1991

Physiological effects of water stress on young corn plants

Creator:: Barlow, Edward William Ross
Abstract:: Laboratory experiments were used to investigate the mechanism of plant response to water stress by determining the sensitivity of leaf elongation, photosynthesis and transpiration in young corn plants to a decrease in leaf water potential. In initial experiments, 9 day old corn plants were grown at soil water potentials of...

Effects of flooding on peach, apple, quince and several pear species

Creator:: Andersen, Peter C.
Abstract:: A series of experiments was designed to investigate differential flood-tolerance and the phenomenon of flood-induced stomatal closure of several fruit tree species. The first two experiments were conducted with potted plants submerged outdoors 5-10 cm above the soil line. Plant morphology, growth, leaf conductance (cL), and soil oxygen diffusion rate...

Analysis of a hydrologic balance model and Penman-Monteith evapotranspiration estimating methods

Creator:: Carrijo, Osmar Alves
Abstract:: The major objectives of this study were an evaluation of the Meteorological Office Rainfall and Evaporation Calculation System (MORECS) evapotranspiration (ET) model using the Penman-Monteith equation and comparison of the MORECS and measured surface resistance. Meteorological, soil and plant parameters were measured in an alfalfa field over two growing seasons....

Spatial analysis and modeling of carbon storage in native shrubs of Senegal's Peanut Basin

Creator:: Lufafa, Abel
Abstract:: Farmlands, grasslands, and savannas in semi-arid sub-Sahelian Africa have the potential to store carbon (C) in soil. There is a great need to manage ecosystems to increase C storage in semipermanent soil pools. This will improve soil quality, impede desertification and by reducing atmospheric CO₂ levels, will slow climate change....

Physiological and yield responses of snap beans (Phaseolus vulgaris) to water availability

Creator:: Biuk, Abdulmajid Ahmed
Resource Type:: Dissertation
Full Text:: , the observed turgor maintenance could not overcome the drastic effects of water deficit on plant

Physiology of flowering in Coffea arabica L. : role of growth regulators and water relations

Creator:: Schuch, Ursula K.
Abstract:: Coffee trees growing in the Kona district of Hawaii were treated with different concentrations of either BA, GA3, or Promalin, and pruned at the time of flowering. No significant differences in the flowering and fruit ripening pattern were found. High concentrations (100 mg/1) of growth regulators decreased fruit fresh weight....
