Response of downy brome (Bromus tectorum) and Kentucky bluegrass (Pao pratensis) to primisulfuron

Creator:: Hendrickson, Paul E.
Abstract:: Glasshouse and growth-chamber experiments were conducted to evaluate primisulfuron phytotoxicity and the influence of adjuvants on downy brome and Kentucky bluegrass. GR₅₀ (50% growth reduction) values were 0.97 ± 0.57 and 8.07 ± 1.85 g/ha for downy brome and Kentucky bluegrass, respectively. Primisulfuron was applied to downy brome and Kentucky...

Seedling recruitment of hairy nightshade and other summer annual weeds in irrigated row crops

Creator:: Peachey, Ronald Edward
Abstract:: This study evaluated the effects of tillage system, rotational tillage sequences, and winter seed burial depth on weed seedling recruitment in irrigated cropping systems. Notill (NT) planting of vegetable crops reduced emergence of hairy nightshade by 77 to 99% and Powell amaranth emergence from 50 to 87% compared to conventional...

Vernalization requirements and seed dormancy of jointed goatgrass (Aegilops cylindrica)

Creator:: Fandrich, Lynn
Abstract:: Jointed goatgrass (Aegilops cylindrica Host) infestations in winter wheat (Triticum aestivum L.) production regions of the central and western USA result in severe economic losses in the wheat market. Field and greenhouse studies were conducted to determine the vernalization requirements of winter wheat, spring wheat, jointed goatgrass, and wheat by...
Resource Type:: Dissertation
Full Text:: . Detailed observations in the greenhouse revealed a longer period between jointing and anthesis for most

ALS-inhibitor resistant downy brome (Bromus tectorum L.) biotypes in Oregon : Mechanism of resistance, fitness, and competition

Creator:: Park, Kee-Woong
Abstract:: Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...

Weed management for giant reed (Arindo donax) biomass production in Oregon

Creator:: Attarian, Amir
Abstract:: Giant reed (Arundo donax L.) is a candidate to provide feedstock for the Portland General Electric power plant in Boardman, Oregon. Giant reed is a fast perennial grass, producing 23-27 metric tons ha⁻¹ of biomass and has the ability to adapt to diverse environments making it a good candidate for...

You are What, When, Where, and How you Eat : Mercury in Avian Food Webs across Multiple Spatial Scales

Creator:: Jackson, Allyson K.
Abstract:: Human alterations of landscapes take many forms, one of which is anthropogenic pollution. Mercury (Hg) is a complex contaminant because its uptake into the food web is not driven entirely by loading to the system; methylation is necessary to make Hg bioavailable and toxic to fish and wildlife. Because methylation...

Comparing Ectomycorrhizal Communities of Understory Giant Chinquapin (Chrysolepis chrysophylla) and Overstory Pinaceae Trees in a Mixed Conifer Forest in Central Oregon

Creator:: Longway, Lucas J.
Abstract:: Giant chinquapin (Chrysolepis chrysophylla) is an evergreen hardwood often found as a shrubby understory component of coniferous forests in the Pacific Northwest United States. Due to its ability to sprout quickly after disturbances such as fire and logging it is often viewed as a pest by forest managers. Like its...

Economic analysis of integrating spatial concerns into harvest scheduling

Creator:: Yoshimoto, Atsushi
Abstract:: An analytical algorithm to formulate a sparser set of adjacency constraints than the conventional algorithm is proposed. Utilizing matrix algebra applied to an adjacency matrix, constraints are systematically and efficiently derived by the proposed algorithm. The proposed algorithm is proved to provide a true set of adjacency constraints in the...

Assessing the impact that professional development training has on the self-efficacy of school counselors, including rural school counselors

Creator:: Millmore, Patrick J.
Abstract:: Boyd and Walter (1975) identified the need to provide supervision for school counselors almost forty years ago. Michelle Obama, the First Lady of the United States (2014), in her address at the American School Counselor Association Conference stated that school counselors needed to be provided with professional development opportunities designed...
