The uptake and retention of cesium-134 in Microtus canicaudus Miller

Creator:: Lei, Wayne
Abstract:: A study was performed to assess the uptake and retention patterns of cesium-134 in the gray-tailed vole, Microtus canicaudus Miller. To furnish a realistic source of contaminated food for the voles, wheat seedlings were raised in hydroponic solutions to provide radiocesium labeled wheat clippings. The hydroponic system was designed to...

Factors influencing sex ratio in the estuarine copepod genus Eurytemora

Creator:: Vander Hart, Archie Lee
Abstract:: An investigation was conducted on factors influencing sex ratio in Eurytemora. Fifteen generations of brother/sister mating have produced family lines with a high proportion of either males or females of Eurytemora affinis. On this basis, a polygenic mechanism of sex determination is proposed for E. affinis. Laboratory experiments on the...

Leaf elongation as a function of soil water potential and photoperiod

Creator:: Hodges, T.
Abstract:: Leaf elongation is a major indicator of plant growth. It is controlled by complex interactions of many factors including light intensity, photoperiod, water availability, atmospheric conditions, and plant water stress. In this study, the response of leaf elongation to length of photoperiod and to plant water stress as indicated by...

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...

Diffusion and surface reaction processes of absorption on surfaces of soil particles in unsaturated soils

Creator:: Yingjajaval, Suntaree
Abstract:: At present the adsorption kinetic of ions by soil particles is considered to be a surface reaction. When the transport of solutes in soils is described using the one-dimensional flow equation, it becomes a serious problem that lateral diffusion of ions from the bulk solution towards the soil surfaces is...

An evaluation of soil warming for increased crop production

Creator:: Rykbost, K. A.
Abstract:: In regions where soil temperatures limit plant growth, artificial soil warming may be an economically feasible practice. This hypothesis was evaluated in a soil warming experiment near Corvallis, Oregon. This experiment was prompted by the observation that multiple use of waste heat discharged in the condenser cooling water of thermal...
