Cytokinin O-glycosyltransferases : biochemical characteristics in vitro and developmental regulation in transgenic plants

Creator:: Veach, Yeonjin Kim
Abstract:: Cytokinins are plant hormones regulating cell division and differentiation. Most developmental events from germination, vegetative morphogenesis to seed and fruit set are influenced by cytokinins. t,ns-Zeatin is the major natural occurring cytokinin. Its isomer, cis-zeatin, and its derivatives are usually present in low quantities and have traditionally been considered as...

Ecology of the predatory mite, Pergamasus quisquiliarum Canestrini (Acari: Mesostigmata)

Creator:: Groth, Eric M.
Abstract:: Pergamasus quisquiliarum Canestini is a polyphagous predatory mite that has been shown to feed on the economically important arthropod, Scutigerella immaculata Newport (Symphyla: Scutigerellidae), Collembola, Diptera larvae, Enchytraeid worms, and miscellaneous other soil organisms. This study examined the feeding behavior of P. quisquiliarum, the effects of cover cropping and tillage...

Pollination and pollinators of pumpkin and squash (Cucurbita maxima Duchesne) grown for seed production in the Willamette Valley of western Oregon

Creator:: Gavilánez-Slone, Jenny M.
Abstract:: 'Golden Delicious' winter squash (GDWS), Cucurbita maxima Duchesne, provides significant amounts of pollen (24 mg) and nectar (236 μl), but with a low reward of 14% nectar sugar. The quantity of nectar produced per GDWS flower differed between sites and floral sex. The GDWS male flowers had 25% higher sugar...

Impact of yeast present during pre-fermentation cold maceration on Pinot noir wine aroma

Creator:: Hall, Harper L.
Abstract:: This research investigated yeast populations and diversity during pre-fermentation cold maceration and alcoholic fermentation of Vitis vinifera L. cv. Pinot noir grapes from a commercial vineyard (Dayton, OR). Fermentations were conducted at the Oregon State University research winery in 100 L tanks while grapes from the same vineyard lot were...

Influence of extractives on the chemical analysis of switchgrass

Creator:: Tandjo, Djuhartini
Abstract:: This thesis summarizes an investigation into the need for removing extractives from herbaceous biomass feedstocks prior to their chemical characterization. Switchgrass (Panicum virgatum), was used in this study as a representative herbaceous biomass feedstock. The influence of extractives on the chemical analysis of switchgrass was done by comparing the composition...

Porosity, surface area and enzymatic saccharification of microcrystalline cellulose

Creator:: Tantasucharit, Usicha
Abstract:: The research described in this thesis was aimed at understanding how particle size, porosity, and enzyme accessible surface area influence the rate of saccharification of microcrystalline cellulose. Microcrystalline cellulose (MCC) is a commonly used substrate for the study of cellulolytic enzymes. MCC preparations of different particle size are commercially available....

The effect of rootstock on the performance of the Vitis vinifera cultivars Pinot noir, Chardonnay, Pinot gris and Merlot

Creator:: Shaffer, Raymond Glen
Abstract:: This study reports finding of two rootstock experiments planted in 1997. The purpose of the first experiment was to evaluate the performance of Pinot noir on 19 phylloxera-resistant rootstocks and as an ungrafted vine. The purpose of the second experiment was to evaluate the performance of V. Vinifera cultivars Pinot...

Biomarkers of oxidative stress and DNA damage in agricultural workers

Creator:: Muniz, Juan Fermin
Abstract:: Pesticides are among the most pervasive environmental contaminants and they are an important potential risk for human health. Agricultural workers are constantly exposed to pesticide spray, drift and residues in the soil and foliage. Many agricultural pesticides are readily absorbed by the body, through contact with the skin, the respiratory...

Development and application of a new passive sampling device : the lipid-free tube (LFT) sampler

Creator:: Quarles, Lucas W.
Abstract:: Contaminants can exist in a wide range of states in aqueous environments, especially in surface waters. They can be freely dissolved or associated with dissolved or particulate organic matter depending on their chemical and physical characteristics. The freely dissolved fraction represents the most bioavailable fraction to an organism. These freely...

Hydrolytic methods for the quantification of fructose-equivalents in herbaceous biomass

Creator:: Nguyen, Stefanie K.
Abstract:: A low, but significant, fraction of the carbohydrate portion of herbaceous biomass may be composed of fructose/fructosyl-containing components (“fructose equivalents”); such carbohydrates include sucrose, fructo-oligosaccharides, and fructans. Standard methods used for the quantification of structural-carbohydrate-derived neutral monosaccharide-equivalents in biomass are not particularly well suited for the quantification of fructose equivalents...
