An intensive chemical investigation, that includes the
determinations of salinity, oxygen, nutrients, pH, alkalinity, and
total carbon dioxide of the Columbia River plume off the Oregon
coast in July 1967 shows the following unique features:
1. Along the axis of the river plume both the salinity minimum and
temperature maximum...
The purpose of this study was to test a proposed procedure for
providing seniors in small high schools of Oregon with information
in regard to the private colleges and universities of the state. It included
the development of an audio-visual technique and its trial on
a sample group.
Scope and...
Sodium polypectate (SPP) was added to an ethanol-streptomycin
agar (ESA) medium to determine if it would provide a selective
substrate for the growth of Verticillium dahliae and for isolation of
the fungus from soil and plant tissues in the presence of saprophytic
fungi. Sodium polypectate improved greatly the formation and...
Verticillium wilt of hops in Oregon, caused by Verticillium
dahliae Kleb., was first reported in 1956. Later, V. albo-atrum
Reinke & Berth. was also isolated from infected hop plants, and thus
both species of the fungus were shown to be the causal agents of the
disease in Oregon.
The purpose...
A cytogeographical study was made of populations of tetraploid
(n=18) and hexaploid (n=27) Achillea millefolium (Compositae-
Anthemideae) from the Pacific Coast states. There is a complex
distributional pattern, involving overlapping ranges, mixed populations,
migration of one form into areas occuplied by the other,
pentaploid hybrids, and septaploid and octoploid plants....
