Xylem discontinuity in Vitis vinifera L. berries

Creator:: Creasy, Glen L.
Abstract:: Several effects of xylem discontinuity in Pinot noir and Merlot grape berries were studied. There was a reduction in the amount of apoplastic dye (Eosin Y or azosulfamide) uptake through cut pedicels into soft versus firm berries, suggesting a reduction in maximal xylem flow at that time. Both greenhouse and...

Inflorescence necrosis, ammonium, and evidence for ferredoxin-glutamate synthase activity in grape (Vitis vinifera L.)

Creator:: Creasy, Glen L.
Abstract:: Death of flower parts near bloom due to inflorescence necrosis (IN) is associated with high ammonium (NH₄⁺) concentration in flower clusters, shade, cool wet weather preceding bloom, and excessive vigor. Faults in NH₄⁺ assimilation are suspected to cause a rise in NH₄⁺ concentration to toxic levels in flower cluster but...

Ammonium Metabolism in Grapes [1992-1993]

Creator:: Creasy, Glen L. and Breen, Patrick J.
Abstract:: Oregon grape growers are sometimes troubled with fruit set problems. There are many types of fruit set disorders, but a recently described one is inflorescence necrosis (IN). Though many studies related to the disorder have been done at OSU and elsewhere, investigation into IN is still in its infancy. Several...

Ammonium Metabolism in Grapes [1993-1994]

Creator:: Creasy, Glen L. and Breen, Patrick J.
Abstract:: The connection between the fruit-set disorder Inflorescence Necrosis (IN) and high ammonium (NI14+) in affected tissues has led to an investigation of NH4+ assimilation enzymes (principally glutamine synthetase (GS) and glutamate synthase) in grape tissues. Previous work in this department has suggested that toxic levels of NH4+ build up in...

Viticultural Factors Affecting Inflorescence Necrosis and Ammonia Metabolism [1995-1996]

Creator:: Creasy, Glen L. and Breen, Patrick J.
Abstract:: Inflorescence Necrosis (IN) has been an unpredictable problem for grape growers in Oregon. The industry has seen significant losses due to this fruit set disorder in several out of the eight years since its first description in 1988, particularly in Pinot noir. Little is known of how to prevent the...

Inflorescence Necrosis and Ammonium in Grape

Creator:: Creasy, Glen L., Price, Steve, and Breen, Patrick J.
Abstract:: Poor set and low yields in 1988 and 1990 were, in part, attributed to Inflorescence Necrosis (IN), a disorder that results in death of flowers and rachis tissue near bloom-time. In isolated areas, IN has caused significant loss of crop in each year since then. Past research at OSU has...

Estimating volume and value on standing timber in hybrid poplar plantations using terrestrial laser scanning : a case study

Creator:: Barnett, Jennifer S.
Abstract:: Terrestrial laser scanning (TLS) may provide a way to increase timber value recovery by replacing manual timber cruising with a simple-to-use, cost-effective alternative. TLS has been studied in several trials worldwide. Past studies have not compared TLS based estimates with mill estimates of stem value and volume. Three differently stocked...

Wood properties and use of sensor technology to improve optimal bucking and value recovery of Douglas-fir

Creator:: Acuna, Mauricio A.
Abstract:: There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...

The Value of New Technology : View Toward Reassessment

Creator:: White, Stephen J.
Abstract:: Abraham Heschel wrote that a philosopher's primary task was not merely to describe and judge the modes and facts of actual human behavior, but also to examine and understand the meaninq of those descriptions and judgements of modes and facts (Bella, 1978). Our values are critically tied to our structures...

Some toxicological aspects of Ruelene, an organophosphate, used systemically to control ectoparasites

Creator:: Smith, Harry Glen
Abstract:: Ruelene was orally administered to three female sheep at a dosage rate of 121.5 mg /kg. The cholinesterase (ChE) activity levels of blood plasma, red blood cells (RBC), and mosquitoes (Aedes aegypti) which had fed on the sheep were tested at various times before and after dosage. Maximum depression of...

Neuroanatomical distribution of androgen and estrogen receptors in the brain of the roughskin newt, Taricha granulosa

Creator:: Davis, Glen Andrew
Abstract:: The gonadal steroids, testosterone and estradiol, are known to be important modulators of neuronal functions and behaviors in most vertebrate species. These steroid hormones also elicit changes in neuropeptide synthesis and secretion, alter specific neurohormone receptor levels, and alter neuronal morphology and electrophysiology. Many of the actions of androgens and...

Abstract:: Proban, Famphur and Tiguvon were administered intravenously, subcutaneously, and orally at varying concentrations to 101 female rabbits. The cholinesterase (ChE) activity levels of both plasma and red blood cells were tested, as was tick and mosquito ChE, at various times before and after dosage. The determinations measured the inhibition of...

Abstract:: A post-failure investigation of a highway embankment constructed over organic and sensitive subsoils was made with a series of field vane tests. The results indicated that the embankment was quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...

Abstract:: Woody biomass transportation costs and market values/costs are strongly correlated with the woody biomass moisture content. Properly managing moisture content can potentially lead to economic and environmental advantages in biomass energy markets. Good management requires accurate moisture content measurements. Therefore, availability of accurate, precise, reliable, and efficient tools to assess...

Abstract:: The thermodynamic and structural effects of highly anisotropic, short-ranged attraction are investigated for single- and four-site interaction models using Wertheim's multi-density graph theory of chemical association. Both models consist of associating hard spheres, where the saturable attraction sites are described by conical wells centered in the hard core and evaluated...

An investigation of factors affecting the optimal output log distribution from mechanical harvesting and processing systems

Creator:: Marshall, Hamish Douglas
Abstract:: Globally the forest harvesting industry is becoming increasingly mechanized. Driving this trend is the desire to increase productivity and reduce cost, as well as to improve labor-related issues. With mechanization comes an in-forest platform for the introduction of state-of-the-art communication and measurement technologies, and powerful on-board computers. These systems have...
