Alternative orchard floor management practices, soil quality, nitrogen fertilizeruptake, and apple tree growth and yield

Creator:: McDonald, Sarah Finger
Abstract:: Orchard floor management (OFM) practices can improve soil function and alter the soil biological community. Soil function is dependent on soil forming materials and on management practices but little is known about how OFM affect orchard soil quality, fertilizer N uptake, or tree growth and production. Research plots were located...

Traditional and molecular approaches to Zucchini yellow mosaic virus resistance in Cucurbita

Creator:: Brown, Rebecca Nelson
Abstract:: Zucchini yellow mosaic virus (ZYMV) is an important disease of Cucurbita worldwide. Resistant cultivars are the best means of control. ZYMV resistance is quantitative in the wild species C. ecuadorensis, and is controlled by at least three genes in tropical C moschata. Very little molecular work has been done in...

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...

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...

Breeding tomato for increased fruit phenolics

Creator:: Boches, Peter S.
Abstract:: The purpose of this research was to develop tools and germplasm for the production of tomatoes (Solanum lycopersicum L.) with high fruit phenolics without the use of genetic engineering. A candidate gene analysis was undertaken to identify genes regulating anthocyanin biosynthesis in tomato fruit (Aft, Abg, atv, and Purple Smudge)....

Microsatellite marker development and molecular characterization in highbush blueberry (Vaccinium corymbosum L.) and Vaccinium species

Creator:: Boches, Peter
Abstract:: Pre-existing Expressed Sequence Tag (EST) libraries (1,305 sequences) and a newly constructed microsatellite-enriched genomic library (136 clones) from the V. corymbosum cultivar 'Bluecrop' were screened for unique Simple Sequence Repeat (SSR)-containing sequences. Our goal was to develop a set of robust SSR markers for use in managing the National Clonal...

Breeding tomatoes for improved antioxidant activity

Creator:: Mes, Peter Jack, 1976-
Abstract:: Purple tomatoes (Lycopersicon esculemtum) were bred by incorporating genes that result in anthocyanin production in the skin of fruits. These genes originally came from related wild species as no naturally occurring genes encoding fruit anthocyanin expression are known within the cultivated species. By combining Aft or Abg with atv or...

Evaluation of Vitis rootstocks for tolerance to low soil pH

Creator:: Taylor, Patrick Andrew
Abstract:: The purpose of this study was to determine the relative tolerance of grafted Vitis rootstocks to low soil pH. In this capacity, the data may be pooled with results from previous investigations to increase the overall aptitude profile of Vitis rootstocks. A potential application of this information is that the...
