Influence of nitrogen form ratio and calcium on greenhouse and field performance of watermelon

Creator:: Lamb, Michael J.
Abstract:: Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai var. Crimson Sweet) was seeded in a commercial peat mix in multicell containers (72 cells-tray⁻¹, 40 cm³-cell⁻¹) in July 1989 and April 1990. In 1989, the medium was amended with CaC0₃ at 10% w:v. In 1990, no CaC0₃ amendment was made. Watermelon seedling...

Substrate production of blueberry : evaluation of soilless media and potassium, nitrogen fertility on growth and nutrition

Creator:: Kingston, Patrick H.
Abstract:: As blueberry (Vaccinium sp.) production has increased in recent decades, a new interest has developed in the cultivation of blueberry in soilless substrate containers. Historically, blueberry has been propagated and grown in soilless substrate at nurseries, but nursery production is short in duration and plants are small relative to a...

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...

Evaluating Alternative Soil Amendments for Organic Northern Highbush Blueberry Cultivation in Sub-Optimal Soils

Creator:: Retano, Andrea
Abstract:: Escalating demand for organic blueberries has driven a significant expansion of northern highbush blueberry (NHB; Vaccinium corymbosum L.) production area. This expansion is particularly pronounced in regions of the Pacific Northwest where native soil conditions are sub-optimal for NHB, notably east of the Cascade Mountain Range of Oregon and Washington,...

Nitrogen fertigation practices to optimize growth and yield of northern highbush blueberry (Vaccinium corymbosum L.)

Creator:: Vargas, Oscar L.
Abstract:: Northern highbush blueberry is a long-lived perennial crop that is well adapted to low soil pH conditions. The plants are often shallow rooted and absorb primarily the ammonium (NH₄) form of nitrogen (N) rather than nitrate-N (NO₃-N). Traditionally, commercial blueberry fields have been irrigated with overhead sprinklers and fertilized using...

Study of Arabidopsis thaliana seed development : occurrence of germinability

Creator:: Hewitt, Jessica
Abstract:: Seed germination sensu stricto is defined as the physiological events before the radicle tip ruptures the covering tissues. The ability of the radicle to elongate (or germination potential) is observed in developing embryos prior to completion of seed maturation. When embryos at early developmental stages, such as globular, heart, torpedo...

A Study of Urban Vegetable Garden and their Soils in Corvallis and Portland, OR

Creator:: Nelson, Michael, II
Abstract:: Urban agriculture (UA) is defined as the production of food crops or livestock within urban areas. Despite its popularity in the United States, research into UA systems suffers from a general underrepresentation of commercial urban systems. As a result, urban growers often have unique technological needs that are unmet by...

Effect of planting method, weed management, and fertilizer on plant growth and yield of newly established organic highbush blueberries

Creator:: Larco, Handell O.
Abstract:: A 0.4 ha planting of blueberry (Vaccinium corymbosum L.) was established in Oct. 2006 to evaluate the effects of cultivar (Duke and Liberty), planting method (flat versus raised beds), weed management (sawdust mulch and hand-weed control; compost plus sawdust mulch with acetic acid, flaming, and hand-weeding used as needed; and...

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...
