Hybrids with abnormal development were obtained when particular
genotypes of Phaseolus vulgaris L. were crossed. The phenotypic
aberrations of the F₁s included retarded growth, chlorosis of the
trifoliate leaves and the formation of adventitious roots on the
hypocotyls. The expression of the abnormalities was dependent on the
temperature. At high...
In 1968 the Oregon Fish Commission (now Oregon Department of Fish and Wildlife) initiated P.L. 88-309 funded studies to develop techniques to spawn and rear several species of bay clams. After our successful spawning and rearing studies, we planted the laboratory-produced juvenile clams on various tideflats of several estuaries to...
Background/Objectives: Advanced glycation end products (AGEs) are implicated in the pathogenesis of atherosclerosis, diabetes and kidney disease. The objective was to describe dietary intake, the dominant source of exposure to AGEs, with carboxymethyl-lysine (CML), a major AGE, in serum and urine, respectively.
Subjects/Methods: Serum and urinary CML were measured in...
Major and minor minerals have been separated from
three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin),
and Leedey). Olivine, hypersthene, diopside, feldspar,
troilite, chromite, phosphate minerals, and metallic
minerals were analyzed for major, minor and trace elements
using instrumental neutron activation analysis and radiochemical
neutron activation analysis techniques. Concentrations
df the...
Boron sprays produced fruit set increases in 'Barcelona'
hazelnut orchards in 1984 and in 1985. The absolute fruit set was
correlated with leaf B content but not with nut B. With relative
fruit set (RFS), B content of nuts in May (r = 0.63**) was more
strongly related to set...
Bush snap beans (Phaseolus vulgaris L.) cvs 'G5O' (Gallatin
50) and 'OSU58' (Oregon 58) were used for anatomical and morphological
studies of their responses to three levels of temperature.
The plants were grown in a controlled chamber under a 16-hour
photoperiod at 60°/50°, 70°/60° and 80°/70°F (day/night temperature),
respectively.
The...
Oregon sweet corn growers face high fertilizer, fuel
and weed control costs; soil compaction, erosion, organic
matter and nutrient depletion; and difficult equipment
operations in muddy fields. An alternative production
system might ease some of these problems.
Testing was begun to evaluate a living-mulch
cropping system for sweet corn (Zea...
Plant hormones regulate progression through the different phases of plant development in response to endogenous and environmental cues. Gene expression studies, as well as genetic and molecular analysis of mutants with altered hormonal responses, are two common approaches to elucidate hormone response pathways. This dissertation compares ovary and fruit development...
