Growth rate and phosphorus uptake of wheat (Triticum aestivum VILL., Host) as a function of soil water suction and soil temperature

Creator:: Fazilat, Mohammad
Abstract:: The effect of soil temperature and soil water suction on the rate of phosphorus uptake and growth rate of wheat (Triticum aestivum VILL. , Host) was studied. Plants were grown in perlite slabs separated from an osmotic solution by a semi-permeable membrane. Measurements were made at temperatures of 10.0, 18.3,...

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...

Growth rate of wheat (Triticum aestivm L., var. Gaines) as a function of moisture stress and nitrogen supply

Creator:: Amujo, Stephen Jimo
Abstract:: The effect of moisture stress and nutrients on the rate of growth of wheat (Triticum aestivum L. Var. Gaines) seedlings was studied. A special apparatus in which the moisture stress of several perlite cells could be maintained constant by osmotic solutions was used. Predetermined amounts of nitrogen were added to...

The effect of plant moisture stress on the physiology and establishment of planted Douglas-fir and ponderosa pine seedlings

Creator:: Cleary, Brian D.
Abstract:: The role of moisture stress in seedling physiology and establishment was studied in both the field environment and laboratory experiments. Plant moisture stress was measured using the pressure chamber technique. This technique was modified and tested using a fascicle of pine needles as a sample, an improvement which allows the...

The use of heated sea water for farming oysters and salmon

Creator:: Breese, Wilbur P. and Oregon State University. Dept. of Fisheries and Wildlife
Abstract:: For oysters, "The objective of these studies was to determine the biological feasibility of using the heated effluent from coastal nuclear power plants for culturing the Pacific oyster, Crassostrea gigas." (p.1) Work included oyster growth experiments, seasonal growth experiments and closed system studies. For salmon, "The objective of these studies...
