Biology and management of Meloidogyne chitwoodi using oxamyl on potato in the western United States

Creator:: David, Nicholas L.
Abstract:: Field trials were conducted during 2001 to 2003 to investigate soil population dynamics of Meloidogyne chitwoodi, tuber symptom suppression using oxamyl, and post-harvest tuber symptom development on short-season potato varieties Russet Norkotah and Russet Nugget (San Luis Valley only). The experiments were located in the San Luis Valley in Colorado,...

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...

Quantitative Trait Loci Associated with the Tocochromanol (Vitamin E) Pathway in Barley

Creator:: Graebner, Ryan C., Wise, Mitchell, Cuesta-Marcos, Alfonso, Geniza, Matthew, Blake, Tom, Blake, Victoria C., Butler, Joshua, Chao, Shiaoman, Hole, David J., Horsley, Rich, Jaiswal, Pankaj, Obert, Don, Smith, Kevin P., Ullrich, Steven, and Hayes, Patrick M.
Abstract:: The Genome-Wide Association Studies approach was used to detect Quantitative Trait Loci associated with tocochromanol concentrations using a panel of 1,466 barley accessions. All major tocochromanol types- α-, β-, δ-, γ-tocopherol and tocotrienol- were assayed. We found 13 single nucleotide polymorphisms associated with the concentration of one or more of...

Space-based lidar measurements of global ocean carbon stocks

Creator:: Behrenfeld, Michael J., Hu, Yongxiang, Hostetler, Chris A., Dall’Olmo, Giorgio, Rodier, Sharon D., Hair, John W., and Trepte, Charles R.
Abstract:: Global ocean phytoplankton biomass (C-phyto) and total particulate organic carbon (POC) stocks have largely been characterized from space using passive ocean color measurements. A space-based light detection and ranging (lidar) system can provide valuable complementary observations for C-phyto and POC assessments, with benefits including day-night sampling, observations through absorbing aerosols...

Successional changes associated with benthic assemblages in experimental streams

Creator:: Busch, David E.
Abstract:: Experimental streams constructed by the Weyerhaeuser Company, Tacoma, Washington, at Kalama Springs, Washington, were used to observe successional changes in the benthos. Community changes were observed relative to experimental manipulations of light intensity and nitrate concentration in two experiments. The development of benthic assemblages was followed for 150 days after...

The Influence of Nitrogen Fertility on Hop Quality, Pest Management, and the Stability of Biological Control

Creator:: Iskra, Anne E.
Abstract:: A multi-year field study was conducted in Oregon and Washington to evaluate the influence of nitrogen fertilization rate and timing on cone quality, nitrate accumulation in cones, severity of powdery mildew (caused by Podosphaera macularis), arthropod pests, and the stability of conservation biological control of the twospotted spider mite (Tetranychus...

Phytophthora ramorum within an Oregon tanoak forest : quantifying inoculum within canopy throughfall vs. soil splash

Creator:: Benemann, Silvia, E.
Abstract:: Phytophthora ramorum continues to cause extensive mortality of tanoaks in southwestern Oregon. Rain readily washes inoculum down through the canopy, causing new infections on the lower parts of the tree and neighboring host plants. Although this aspect of dispersal is well understood, the relative importance of infested soil and leaf...

Development of in vitro lily scale budlets as related to virus elimination

Creator:: Ruttum, Joanne C.
Abstract:: Lily hybrids vary in their ability to produce virus-free (VF) bulblets when grown from virus-infected scales in tissue culture. Asiatic hybrids typically produce a higher percentage of in vitro VF scale bulblets than do Lilium longiflorum cultivars. Three hypotheses concerning the cause of this variation are tested on five lily...

Ozone flux in Helianthus annuus (L.)

Creator:: Smith, Elaine D.
Abstract:: Sunflower (Helianthus annuus L., cv. NK894) seedlings, grown hydroponically, were exposed to ozone concentrations of 0.0, 0.1, 0.2, and 0.3 ppm at 60% RH, or 0.0 and 0.3 ppm at 30% and 90% RH, for 6 h/d, for four consecutive days, at ages 15 to 18 days from seeding. Plant...
