Cytokinin oxidase activity from Phaseolus vulgaris L. cv. Great Northern callus tissues

Creator:: Chatfield, J. Mark
Abstract:: Cytokinin oxidase activity in callus tissues of Phaseolus vulgaris L. cv. Great Northern has been examined using an assay based on the oxidation of radioactively labeled N⁶ -(Δ² -isopentenyl) adenine (i⁶Ade) to adenine (Ade). Conditions for the quantitative extraction and assay of the enzyme have been established. The substrate specificity...

Location of prune dwarf and prunus necrotic ringspot viruses in sweet cherry pollen and fruit

Creator:: Kelley, Randall David
Abstract:: The location of prune dwarf virus (PDV) and Prunus necrotic ringspot virus (PNRSV) in pollen and seed from infected and healthy sweet cherry trees pollinated with infected pollen was investigated. Virus-like particles were observed in the cytoplasm of pollen grains from PDV-infected cherry trees using transmission electron microscopy. No particles...

Distributional patterns and taxonomic structure of diatom assemblages in Netarts Bay, Oregon

Creator:: Whiting, Mark Carlos
Abstract:: Epiphytic, planktonic and benthic diatom assemblages were investigated in Netarts Bay, Oregon. Samples were collected for a one-year period from February 1980 to March 1981. A planktonic flora was observed only during periods of offshore enrichment when marine neritic species were abundant and were transported into the bay by tidal...

Biosystematic studies of Phacelia capitata (Hydrophyllaceae), a species endemic to serpentine soils in southwestern Oregon

Creator:: Shelly, J. Stephen
Abstract:: Phacelia capitata Rruckeberg is a member of the Phacelia magellanica polyploid complex (species group Magellanicae), a group of wide-ranging, polymorphic perennials in western North America related to the South American P. secunda (= P. magellanica). The purpose of this project was to determine, to the extent possible, the interrelationships of...

The source area for coarse woody debris in small streams in western Oregon and Washington

Creator:: McDade, Mary Helen
Abstract:: Large organic debris has important biological and physical roles within the stream ecosystem. In order to determine the source area of large organic debris in streams, thirty-nine streams in the Cascade and Coast Ranges of Oregon and Washington were sampled. The distance from point-of-origin to channel was measured for thirty...

Microbial analysis of coniferous forest and nursery soils : effects of ectomycorrhizae, volatiles, and humic-rich organic substrates

Creator:: Schisler, David Albert
Abstract:: Fusarium spp. frequent conifer nursery soils yet are rarely recovered from coniferous forest soils. Experiments were performed to determine what influence humic-rich organic amendments and volatiles from soil, ectomycorrhizal fungi and ectomycorrhizae have on the populations of several physiologic and taxonomic microbial groups potentially related to this phenomenon. A comparative...

Autecology, reproductive ecology, and demography of Astragalus australis var. olympicus (Fabaceae)

Creator:: Kaye, Thomas N.
Abstract:: The goal of this study was to gather information on the autecology, reproductive ecology, and population dynamics of Astragalus australis var. olympicus as a baseline for conservation strategies and to help explain its restricted range. Approximately four thousand individuals occurred in four known population centers in the Olympic Mountains, Olympic...

The structure and dynamics of old-growth Sitka spruce (Picea sitchensis) forest of the Oregon Coast Range

Creator:: Quaye, Eric Charles
Abstract:: The objectives of this study are to: 1) study the variations among stands of old-growth Sitka spruce forest located within a relatively restricted geographical area, 2) determine the relationship between species distribution, vegetational pattern, and such site factors as slope and aspect, and 3) ascertain the abruptness of phytosociological change...
