Unfertilized ova from spring chinook salmon (Oncorhynchus
tshawytscha) were examined for the presence of classical salmonid
inmmunoglobulin. Immunodiffusion techniques in which rabbit anti-salmonid
immunoglobulin was reacted against an ova homogenate
and rabbit anti-ova homogenate was reacted against immune chinook
serum failed to detect classical-type antibodies within these eggs.
A lectin...
The detection and antigenic nature of the causative Corynebacterium
of bacterial kidney disease and chemotherapy of this disease
in juvenile coho salmon (Oncorhynchus kisutch) were examined.
Each of 207 yearling coho salmon collected from a population
undergoing a severe epizootic of bacterial kidney disease were examined
for the presence of...
A rootstock trial was established in 1997 at the OSU Woodhall vineyard, located in the Southern Willamette Valley, which included two experiments. The first experiment was a factorial of four varieties grafted on to 9 rootstocks, and also as ungrafted vines (a split-plot design). The second experiment was a randomized...
The structural component compositions of thirty nine non-commercial Pacific
Northwest grasses were analyzed in order to develop a database of the grasses that
may have application in bioconversion processes. The samples were chosen based on
near infrared reflectance (NIR) data that suggested this group of grasses, collectively,
was representative of...
The literature available on the silica content of herbaceous biomass, and its relative mobility in leaching/extraction systems, includes studies that have employed several different methods for silica quantification. This makes comparison of the data difficult. The objective of this thesis research was to determine the quantitative relationships between the measured...
Legislation to reduce open field burning in grass seed fields within the Willamette valley of western Oregon changed established production practices. In the creeping grasses such as Kentucky bluegrass (Poa pratensis L.) and creeping red fescue (Festuca rubra L.) non-thermal management resulted in reduced yield. Studies were conducted to examine...
Three experiments were conducted (1) to develop and characterize
polyclonal antibodies against ovine adipocyte plasma membranes (APM),
(2) to evaluate the effect of administering the developed antibodies to
lambs on lamb growth and carcass characteristics, and (3) to investigate
the possibility of using the developed antibodies to identify antigenic
components...
Juvenile coho salmon (Oncorhynchus kisutch) of three transferrin
genotypes (AA, AC and CC) were experimentally infected with the
causative agent of bacterial kidney disease (BKD) and mortalities
observed. Six experimental and control groups were used:
(1) bacteria-infected + no Fe⁺³ ; (2) bacteria-infected + low Fe⁺³
levels; (3) bacteria-infected +...
The phytohormones auxin and cytokinin control plant development through a complex network of interactions which include synergistic, additive, and opposite effects whose mechanisms are unknown. The auxin-insensitive diageotropica (dgt) mutant provided a tool to dissect the relationship between auxin- and cytokinin-induced responses in tomato. Morphological, physiological, and molecular data support...
This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
