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...

Water injection into the seed zone as an aid to emergence of dryland cereals

Creator:: Estes, James Patrick
Abstract:: An adequate stand at the optimum time is an important factor affecting potential yield and soil erosion control. However, obtaining adequate stands of fall planted winter wheat in the dryland areas of the Pacific Northwest is often complicated by marginal seed zone soil moisture. The purpose of this laboratory study...

Full Text:: relationship of seed water content, diffusivity and hydraulic conductivity with the seed water potential of

Physiological and yield responses of meadowfoam to water stress and nitrogen fertilization

Creator:: Pearson, Calvin H.
Resource Type:: Dissertation
Full Text:: replications and three treatments. 7. Relationship between plant water potential and leaf resistance of field

Water relations of 'Olympus' strawberry and the growth response to drip irrigation and polyethylene mulch

Creator:: Renquist, A. Richard
Resource Type:: Dissertation
Full Text:: Post-harvest Defoliation 11 Water Relations Physiology 12 Plant Water Status and Response to Water

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...

Summer soil moisture dynamics in a young Douglas-fir plantation as influenced by three herbaceous weed communities

Creator:: Preest, David Stanley
Abstract:: The use of chemicals such as the triazines (especially atrazine) and mixtures of the triazines and 2,4-D or 2,4,5-T has become almost standard practice in some parts of the world for selectively controlling grasses and other herbaceous weeds to conserve moisture for and/or prevent the smothering of newly-planted conifers. In...

The effect of different fuels on the quality of boiled water

Creator:: Morrison, Vance L.
Resource Type:: Undergraduate Thesis
Full Text:: effect on plant growth of water boiled over a wood fire as compared to water boiled over a coal fire, a

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....
Resource Type:: Dissertation
Full Text:: used by plants in transpiration plus the water evaporated from soil and plant surfaces

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....
