A georeferenced digital image analysis of micro-topographic patterns within the Willamette Floodplain Research Natural Area, W. L. Finley National Wildlife Refuge

Creator:: Anderson, Karen L.
Abstract:: The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...

Vegetation ecology of Fraxinus latifolia communities in William L. Finley National Wildlife Refuge, Oregon

Creator:: Heinitz, Eric Fajen
Abstract:: Composition and structure of Oregon ash (Fraxinus latifolia) woodlands in the William L. Finley National Wildlife Refuge, Oregon are described. Twenty stands dominated by Fraxinus latifolia were sampled with 500 m2 circular macroplots in which floristic microplot data were collected for plant community synthesis. Plant communities were identified by computer-assisted...

Architecture, size, and reproduction in plants : a pollination study of Mertensia ciliata (James) G. Don

Creator:: Geber, Monica
Abstract:: I experimentally test the hypothesis that the potential for selfing increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible, profusely-flowering perennial. This follows from the premises that 1) pollen dispersal by pollinators between flowers is limited, and 2) individual pollinators, in this study bumblebees, will visit more flowers per...

A frenet theorem for regular null curves in L³

Creator:: Kiyak, James Walter
Abstract:: Regular null curves in Regular null curves in L³ always have a time component parametrization. This fact puts the Frenet equations for regular null curves in L³ in a simple form. A fundamental existence and uniqueness theorem for regular null curves in L³ is proved, and applications to geometry are...

Characterization of an architectural mutant of bean (Phaseolus vulgaris, L.)

Creator:: Guner, Nihat
Abstract:: Genetic and morphological characteristics of an architectural mutant in common beans were studied. The mutant had shiny, dark green leaves, overlapping leaflets, short petioles and a reproductive terminal bud even though the line did not carry the fin gene. Branching was nearly absent resulting in a single stem vine. This...

Frost resistance of pea genotypes (Pisum sativum L.) grown in the field on ground level and raised beds, and under controlled laboratory conditions

Creator:: Becwar, Michael Ryan
Abstract:: The effect of raised bed culture on winter survival of ten pea genotypes (Pisum sativum L.), differing in inherent cold hardiness and growth habit, was studied under two climatic conditions: a moist semi-maritime winter (Corvallis, Oregon) and a cold continental winter (Weston, Oregon). An assessment of winter injury was based...

Effects of Biochar-Based Seed Coatings on Seed Germination and Seedling Vigor of California Brome (Bromus carinatus L.) and Blue Wildrye (Elymus glaucus L.)

Creator:: James, Matthew Scott
Abstract:: California brome and blue wildrye are important native grass species in the Pacific Northwest. However, both species have been reported to have low emergence under less than favorable field conditions. Seed coating is used to improve emergence and stand establishment of various crops. Three studies were carried out to determine...

Decay caused by infection of Fomes cajanderi Karst : in top-broken, young-growth Douglas-fir trees

Creator:: Cahill, James M.
Abstract:: A glaze storm of exceptional severity was seen in the Corvallis area, January, 1942. The weight of ice that accumulated in the crowns of young-growth Douglas-fir trees caused widespread top breakage in many stands lying in the broad path of this storm. Early research on this phenomenon showed the majority...

The inheritance of pod detachment force in green beans (Phaseolus vulgaris L.)

Creator:: McCluskey, Rebecca L.
Abstract:: The easy picking characteristic, expressed as low pod detachment force (PDF), offers a way to decrease pod damage in bush green beans mechanically harvested for processing and fresh market, and makes hand picking easier and faster. This study was undertaken to examine inheritance in a cross of two green bean...

Inheritance of resistance to the lentil strain of pea seedborne mosaic virus in Pisum sativum L.

Creator:: Kasimor, Kathryn T.
Abstract:: The inheritance mode of pea-resistance to the Lentil Strain of Pea Seedborne Mosaic Virus (PSbMV-L) was studied. In addition, commercial pea cultivars, Plant Introduction (P.I.) lines and Oregon State University (OSU) breeding lines were tested for susceptibility to this virus. These lines were also tested for their reaction to Bean...
