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...

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....

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

Creator:: McCoy, Edward L.
Abstract:: The principles of continuum mechanics provide a consistent framework for the derivation of mathematical statements describing transport of water and solute, and growth in plant tissue. These derivations are based upon the explicit consideration of the tissue as a mathematical continuum composed of a cell wall matrix, water, and solute...

Creator:: Ezenwa, Matthew Ikechuku Sunday
Abstract:: Vegetation as a soil-forming factor was studied under forest transition and grass while attempting to keep other soil forming factors constant in the western part of the Willamette Valley, Oregon. The physiographic units consist chiefly of the interior foothills and slopes formed from an old basaltic flow with some interspersed...

Creator:: Sanchez, Ramon M.
Abstract:: Rates of germination and emergence of corn were measured as influenced by soil physical parameters using blotter paper and a sandy loam soil as growth media. The corn seeds used were a hybrid of Funk's (DJ7xLH93). Experimental conditions were soil temperature of 20°C, 25°C, 30°C, and 35°C, soil water potential...

Creator:: Myhrum, Ronald P.
Abstract:: This study was undertaken to determine both the amount and the spatial variability of sand, silt, clay, and six fractions of coarse fragments in soils representing harsh sites for reforestation. Particle size data were collected because of their direct relationship to water holding capacity and the plantability and survivability of...

Creator:: Jensen, Mark E.
Abstract:: Relationships between sagebrush-dominated plant communities and soil-site characteristics were examined on 372 relatively undisturbed rangeland sites of the Humboldt National Forest, in northeastern Nevada. Plant species production data were analyzed by TWINSPAN to develop a hierarchical, floristic-based community type (C.T.) classification. Seventeen C.T.s were identified in this analysis and named...
