Suitability of diverse composts as soil amendments for highbush blueberry (Vaccinium corymbosum L.)

Creator:: Costello, Ryan C.
Abstract:: Highbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and acidic pH. Composts provide organic matter and nutrients for growing blueberry in mineral soils, but many composts are high in pH and soluble salts. Acidification with elemental sulfur (S°) can remedy high pH, but the process...

Horticultural weed control : 1988 report

Creator:: Oregon State University. Department of Horticulture
Abstract:: Crops were grown at the experimental farms using accepted cultural practices within the limits of experimentation trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with two to five replications. Herbicide treatments were applied uniformly with precision plot sprayers or granular formulations were distributed from...

A closed root environment for plant production

Creator:: Blackburn, Bryan (Bryan Keith), 1955-
Abstract:: Thesis research focused on: 1) Water and fertilizer gradients within the plant root zone, and effects of chemical and physical gradients on Trichoderma harzianum populations. 2) Regulation of root growth physically with permeable fabric containers and chemically with copper compounds. 3) Effects of copper coatings for fabric containers on Glomus...

Weed Management, Training, and Irrigation Practices for Organic Production of Trailing Blackberry: II. Soil and Aboveground Plant Nutrient Concentrations

Creator:: Dixon, Emily K., Strik, Bernadine C., and Bryla, David R.
Abstract:: Organic production of blackberries is increasing, but there is relatively little known about how production practices affect plant and soil nutrient status. The impact of cultivar (Black Diamond and Marion), weed management (nonweeded, hand-weeded, and weed mat), primocane training time (August and February), and irrigation (throughout the summer and none...

Vine morphology and influence of shading on yield, fruit quality, and flower bud initiation in hardy kiwifruit (Actinidia arguta)

Creator:: Tiyayon, Chantalak
Abstract:: Morphology of Actinidia arguta (Sieb. et Zucc) Miq. 'Ananasnaya' vines was studied at two sites in Oregon in 1998 and one site in 1999. Three-year-old vines at site 1 and 8-year-old vines at site 2 were observed. Five types of fruiting wood were studied: spur; one-year-old from the cordon, from...

Overexpression of antioxidant genes in transgenic tomato tolerant against multiple stresses

Creator:: Wang, Yueju
Abstract:: The effect of increased manganese superoxide dismutase (Mn-SOD) and cytosolic ascorbate peroxidase (cAPX) on various abiotic stresses was studied using transgenic tomato (Lycopersicon esculentum) plants. Transformants were selected in vitro based on kanamycin resistance, confirmed by PCR and northern blot analyses. Northern blots showed an enhanced gene expression of Mn-SOD...

Using rootstocks to manipulate vine physiological performance and mediate changes in fruit and wine composition

Creator:: Sampaio, Tiago Luís Barros
Abstract:: A rootstock trial was established in 1997 at the OSU Woodhall vineyard, located in the Southern Willamette Valley, which included two experiments. The first experiment was a factorial of four varieties grafted on to 9 rootstocks, and also as ungrafted vines (a split-plot design). The second experiment was a randomized...

The need to breed crop varieties suitable for organic farming using wheat, tomato and broccoli as examples: A review

Creator:: Lammerts van Bueren, E. T., Jones, S. S., Tamm, L., Murphy, K. M., Myers, J. R., Leifert, C., and Messmer, M. M.
Abstract:: It is estimated that more than 95% of organic production is based on crop varieties that were bred for the conventional high-input sector. Recent studies have shown that such varieties lack important traits required under organic and low-input production conditions. This is primarily due to selection in conventional breeding programmes...

Interactions of Amphorophora agathonica Hottes with raspberry viruses and resistant red and black raspberry

Creator:: Lightle, Danielle
Abstract:: In recent years, red raspberry production in Washington and British Columbia has been severely limited by a newly emerged virus complex that causes symptoms of crumbly fruit. The complex is comprised of three viruses: Raspberry bushy dwarf virus (RBDV), Raspberry leaf mottle virus (RLMV) and Raspberry latent virus (RpLV). Both...
