Experiments were conducted under controlled environments to
investigate the influence of nutrient supply and panicle removal on
tiller and panicle production in orchardgrass. Propagules of two
clones, MID-5 (Clone 0), from the synthetic variety Pennlate, and
Clone B, a locally adapted clone, were utilized for these studies.
Tiller production was...
Morphological changes in five clonally propagated genotypes
of Agrostis L. resulting from variations in environment were
studied in six natural environments extending from southern Oregon
to northern British Columbia. These same clones were also subjected
to four different cutting heights in turf plots. In addition to
the field experiments, they...
More than 2,000 male newts were collected during the summer
and maintained unfed at 10°C both pre- and post-irradiation.
Exposures ranging up to 30 kR were given with 300 kVp X-rays and
⁶⁰Co gamma rays. Half of the newts were injected (I. P.) with 15 g
DMSO/kg (the maximum sublethal...
A method for measuring food carbon assimilation in the copepod
Calanus finmarchicus was developed, using the diatom Ditylum
brightwelli as food. The amount of particulate food carbon ingested
was determined as the difference between CHN analyzer analyses for
particulate food carbon of pre- and post-grazed food suspensions.
The fraction of...
Industrial training in the Fashion Apparel Industry is confronted with difficult objectives. In this industry, continual style and fabric change challenge the effectiveness of conventional industrial training techniques and concepts. To meet this challenge, the "Self-Help" training concept was developed. "Self-Help" centers around the philosophy of training sewing machine operators...
The pathogenicity of A. flavus on alkali bee larvae was studied
using sample materials from three nesting sites of these soil
inhabiting bees along the Oregon-Washington state line. Soil
saprophytes of the biosphere of the alkali bee were also studied.
Field observations and direction of soil cores from bee beds...
