The effect of soil moisture suction and soil temperature on transpiration, photosynthesis and respiration in Monterey pine (Pinus radiata D. Don)

Creator:: Babalola, Olaoluwa
Abstract:: A special apparatus was developed in which the soil moisture levels of several soil cells could be maintained independently by various osmotic solutions at a selected temperature. The effect of four soil moisture suctions and four soil temperatures on the rates of transpiration, photosynthesis and respiration of monterey pine seedlings...

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...

Amount and chemical composition of understory vegetation in Alsea basin forest communities

Creator:: Tarnócai, Charles
Abstract:: The understory vegetation was sampled in eight plant communities of a Douglas-fir ecosystem to determine the organic matter production and mineral composition. Four sample sites were selected in each plant community and the understory vegetation sampled using the method of quadrats of successively increasing size. All herbaceous plants were separated...

Clay mineralogy and related chemical properties of soils formed on Mazama pumice

Creator:: Chichester, Frederick Wesley
Abstract:: A sequence of soil profiles was sampled along a climate-vegetation transect on the dated Mazama pumice fall in central Oregon. The <2 μ size fraction from each sample was characterized with respect to the relative significance of amorphous and crystalline components, and the individual minerals of the latter group were...

Effect of snowbrush on the establishment and growth of Douglas-fir seedlings

Creator:: Scott, William
Abstract:: Six, recent clear cut areas were selected in the Douglas-fir zone of the Western Cascade Range of Oregon to determine the environmental and nutritional effects that snowbrush has on the establishment and growth of Douglas-fir seedlings. One thousand eighty milacre sample plots on the six clear cuts were used to...
