Tests On The Elaboration Of Soybean Milk, Derivatives, And Industrial Feasibility Project, Ciro Pablo Kopp Valdivia

Theses and Dissertations

This work was done with the purpose of evaluating different forms of soybean milk processing, the product acceptance by the public, and to do a study on the feasibility for the production of milk at a small scale to be used as a nutritional supplement in school breakfasts. The soybean milk was prepared with 2 varieties "(Cristalina and Doko)" and two periods of enzymatic inactivation (Before and After) of the grain mush. The "organoleptic" quality was evaluated through surveys and its posterior statistical analysis. Parameter quality was also considered just as did the microbiologic analysis and the conservation tests. The …

Influence Of A Mycorrhizal Fungus And/Or Rhizobium On Growth And Biomass Partitioning Of Subterranean Clover Exposed To Ozone, Joseph E. Miller, Steven R. Shafer, Michele M. Schoeneberger, Walter A. Pursley, Stephanie J. Horton, Charles B. Davy

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The influence of soilborne symbionts such as rhizobia or mycorrhizal fungi on plant response to ozone (O₃) has not been well defined. Leguminous plants in the field are infected by both types of organisms, which influence plant nutrition and growth. We studied the effects of infection with Rhizobium leguminosarum biovar trifolii and/or Gigaspora margarita on response of subterranean clover (Trifolium subterraneum L. cv Mt. Barker) to O₃. Exposures were conducted in greenhouse CSTR chambers using four O₃ concentrations [charcoal-filtered (CF), 50, 100, or 150 ppb; 6 h day^-1, 5 day wk^{-1 …}

Season And Genotype Influence Golf Ball Roll Distance On Creeping Bentgrass, A.M. Rist, Roch E. Gaussoin, Bob Shearman, J.D. Fry, Walter W. Stroup

Department of Agronomy and Horticulture: Faculty Publications

Golfers are demanding increased ball roll distances on a daily basis, but cultural practices to achieve this often are detrimental to the green. One option for increasing ball roll distance without altering cultural practices may be to select creeping bentgrass genotypes that provide less resistance to ball roll. Studies were conducted at the John Seaton Anderson Turfgrass and Ornamental Research Facility near Ithaca, Neb., and at the Rocky Ford Turfgrass Research Facility in Manhattan, Kans., to determine genotype and seasonal influences on golf ball roll distance. Eighteen creeping bentgrass (Agrostis palustris Huds.) genotypes were evaluated. Genotype was not a …

Soil Temperature And Fumigation Effects On Plant Phosphorus Uptake And Related Microbial Properties, Dennis L. Mccallister, L. A. Jawson, M. D. Jawson

Department of Agronomy and Horticulture: Faculty Publications

Early season problems with growth of corn (Zea mays L.) under cool, wet conditions prompted a study of the effects of soil and environmental conditions on mineralization and plant uptake of phosphorus (P). Our objective was to determine the effect of soil test P, temperature, and soil fumigation on soil P availability and uptake during early corn growth. Corn was grown in growth chambers at temperatures of 14°C or 25°C. Soils were a high-P Hastings silty clay loam (fine, montmorillonitic, mesic Udic Argiustoll) and a low-P Sharpsburg clay loam (fine, montmorillonitic, mesic Typic Argiudoll). Plants grew for up to …

Yield Of Wheat Across A Subambient Carbon Dioxide Gradient, Herman S. Mayeux, Hyrum B. Johnson, H. Wayne Polley, Stephen R. Malone

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Yields and yield components of two cultivars of day-neutral spring wheat (Triticum aestivum L.) were assessed along a gradient of daytime carbon dioxide (CO₂) concentrations from about 200 to near 350 µmol CO₂ (mol air)^–1 in a 38 m-long controlled environment chamber. The range in CO₂ concentration studied approximates that of Earth’s atmosphere since the last ice age. This 75% rise in CO₂ concentration increased grain yields more than 200% under well-watered conditions and by 80–150% when wheat was grown without additions of water during the last half of the 100-day growing season. …

Environmental Requirements For Sporocarp Germination In Marsileaceae, Kevin J. Kruep

Masters Theses

Experiments were conducted on sporocarps of Marsilea quadrifolia L. to determine whether temperature had any influence on the length of the reproductive period and initial sperm emergence from microgametophytes. Data were then compared to results of similar studies undertaken with the species M. vestita Hooker and Greville to determine whether there was any variation between them. A slight variation was recorded, ranging from 1 to 1.5 hours for initial emergence.

An additional set of experiments was performed with 58 year old sporocarps and approximately two-year-old sporocarps of M. quadrifolia. A difference of 2-6.5 hours for initial sperm emergence occurred between …

Macrophyte-Macroinvertebrate Interactions In A Lentic Ecosystem And The Effect Of Fluridone Treatment To Control Myriophyllum Spicatum L., Gregory J. Moeller

Dissertations and Theses @ UNI

Myriophyllum spicatum L. is an exotic macrophyte that can become pestiferous in lentic ecosystems. Two field studies were conducted to investigate: 1) epiphytic macroinvertebrates associated with M. spicatum and native macrophytes; and 2) epiphytic macroinvertebrate community response to fluridone treatment for M. spicatum control.

In the first study evaluating epiphytic macroinvertebrates associated with M. spicatum and native macrophytes, triplicate samples were collected at three sites in both Auburn and Zumbra Lakes, Minnesota, USA. One site in each lake contained primarily M. spicatum, the second site contained M. spicatum and native vegetation, and the third site was dominated by native …

Helminths Of The Southwestern Toad, Bufo Microscaphus, Woodhouse's Toad, Bufo Woodhousii (Bufonidae), And Their Hybrids From Central Arizona, Stephen R. Goldberg, Charles R. Bursey, Keith B. Malmos, Brian K. Sullivan, Hay Cheam

Great Basin Naturalist

The gastrointestinal tracts, lungs, and urinary bladders from 77 Bufo microscaphus, 61 Bufo woodhousii, and 8 of their hybrids were examined for helminths. One species of trematode (Glypthelmins quieta), 1 species of cestode (Distoichometra bufonis), and 5 species of nematodes (Aplectana incerta, A. itzocanensis, Rhabdias americanus, Physaloptera sp., and Physocephalus sp.) were found. The greatest prevalence (41%) and mean intensity (231.7) were recorded for Aplectana incerta in Bufo woodhousii. It appears hybrids harbor fewer parasites than either parent species.

Cross-Polarized Magic-Angle Spinning 13c Nuclear Magnetic Resonance Spectroscopic Characterization Of Soil Organic Matter Relative To Culturable Bacterial Species Composition And Sustained Biological Control Of Pythium Root Rot, Michael J. Boehm, Tianyun Wu, Alex G. Stone, Bart Kraakman, Donna A. Iannotti, G. Edwin Wilson, Laurence V. Madden, Harry A.J. Hoitink

Department of Plant Pathology: Faculty Publications

We report the use of a model system that examines the dynamics of biological energy availability in organic matter in a sphagnum peat potting mix critical to sustenance of microorganism-mediated biological control of pythium root rot, a soilborne plant disease caused by Pythium ultimum. The concentration of readily degradable carbohydrate in the peat, mostly present as cellulose, was characterized by cross-polarized magic-angle spinning 13C nuclear magnetic resonance spectroscopy. A decrease in the carbohydrate concentration in the mix was observed during the initial 10 weeks after potting as the rate of hydrolysis of fluorescein diacetate declined below a critical threshold level …

Managing Pastures For Long-Term Prosperity, Hugh Pringle, Jenny Riches

Natural resources published reports

A Workshop held by the Sandstone Land Conservation District Committee

Lake Mason Station

April 1994

A workshop hosted by Sandstone Land Conservation District Committee (LCDC) was held at Lake Mason station on 28 April 1994. This workshop was based on two previous workshops hosted by the Kalgoorlie and north-eastern Goldfields LCDCs in May 1991 (Pringle et al. 1992). The success of the earlier workshops prompted the rangeland survey team in association with the Sandstone LCDC and the Kalgoorlie District Office of Agriculture Western Australia to initiate the project.

The aims were to provide a summary of local wisdom regarding pasture …

Forage Quality Of "Matua" Prairie Grass, Kelly King

Masters Theses & Specialist Projects

Research on the nutritive quality of Matua grass (Bromus willdenowii) is limited in south central Kentucky-Due to the hot summers, mild winters and a 200-day long growing season in Kentucky, herbage quality as well as management practices may differ from those reported in research from other climates. The objective of this study was to evaluate the nutritive quality of five forages (Matua, Gala, Smooth bromegrass, Tall fescue and Orchardgrass). The experiment was conducted on a Pembroke silt loam (fine-silty, mixed, mesic mollic Paleudalfs) in south central Kentucky as well as in the greenhouse. Four harvests each were obtained from the …

Patch Diseases In Kentucky Bluegrass Lawns, Paul C. Vincelli, A. J. Powell Jr.

Agriculture and Natural Resources Publications

“Patch diseases” can be very destructive when Kentucky bluegrass is grown under intensive management. Two patch diseases with similar symptoms can occur. Necrotic ring spot often appears in early summer. Summer patch, the more common disease in Kentucky landscapes, develops in middle to late summer.

These diseases are often a concern in lawns under intensive management for two reasons:

1. Improper application of certain lawn management practices, such as close mowing, can aggravate disease development.
2. When a lawn receives significant inputs of fertilizer and irrigation and frequent mowing, the homeowner or landscape manager usually has high aesthetic expectations and tolerates …

Iron Uptake By Symbiosomes From Soybean Root Nodules., Kristin Levier, David A. Day, Mary Lou Guerinot

Dartmouth Scholarship

To identify possible iron sources for bacteroids in planta, soybean (Glycine max L. Merr.) symbiosomes (consisting of the bacteroid-containing peribacteroid space enclosed by the peribacteroid membrane [PBM]) and bacteroids were assayed for the ability to transport iron supplied as various ferric [Fe(III)]-chelates. Iron presented as a number of Fe(III)-chelates was transported at much higher rates across the PBM than across the bacteroid membranes, suggesting the presence of an iron storage pool in the peribacteroid space. Pulse-chase experiments confirmed the presence of such an iron storage pool. Because the PBM is derived from the plant plasma membrane, we reasoned that it …

A Novel Iron-Regulated Metal Transporter From Plants Identified By Functional Expression In Yeast., David Eide, Margaret Broderius, Jeanette Fett, Mary Lou Guerinot

Dartmouth Scholarship

Iron is an essential nutrient for virtually all organisms. The IRT1 (iron-regulated transporter) gene of the plant Arabidopsis thaliana, encoding a probable Fe(II) transporter, was cloned by functional expression in a yeast strain defective for iron uptake. Yeast expressing IRT1 possess a novel Fe(II) uptake activity that is strongly inhibited by Cd. IRT1 is predicted to be an integral membrane protein with a metal-binding domain. Data base comparisons and Southern blot analysis indicated that IRT1 is a member of a gene family in Arabidopsis. Related sequences were also found in the genomes of rice, yeast, nematodes, and humans. In Arabidopsis, …

The Effects Of Osmotic Potential On Ammonification, Immobilization, Nitrous Oxide Production, And Nitrification Rates In Penoyer Soil, Andrew P. Low

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An isotopic dilution method was used to test the effects of osmotic potential, (𝛹_s), upon nitrification, ammonification, N-immobilization, and nitrous oxide production rates in soil at solute concentrations encountered in Penoyer soil. A nitrification potential assay was also performed to approximate maximum nitrification rates.

Nitrification potential rates in soil slurries exponentially declined in response to decreased osmotic potential. However, nitrification was independent of salt concentration at the ambient NH₄⁺ concentrations of the soil. The differential response was attributed to the variable NH_4⁺ substrate quantities. The effects of osmotic potential were secondary to NH_{4 …}

Livestock As Seed Disseminators For Reseeding Degraded Rangelands: The Role Of Dung In Gap Formation And Plant Establishment, Brian S. Auman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Livestock (cattle and sheep) were examined as seed disseminators for reseeding degraded Intermountain rangelands. "Hycrest" crested wheatgrass [Agropyron desertorum (Fisch. ex Link) Schult. X A. cristatum (L.) Gaert.] seed was fed to yearling Holstein steers and Suffolk ewes. Dung was collected from each animal type and deposited on plots of high and low densities of an annual [cheatgrass (Bromus tectorum L.)] and perennial [squirreltail (Sitanion hystrix Nutt.)] grass species. The experiment evaluated the ability of the dung to suppress the resident vegetation, and the recruitment and establishment of Hycrest seedlings emerging from the dung.

Sheep dung had …

Growth Responses Of Great Basin Plant Species To Variation In Nitrogen Availability, Carol J. Bilbrough

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For this dissertation, I examined the ability of field-grown plants to capture N presented in enriched patches or in whole-plant pulses. I assessed root proliferation in N-enriched patches when Agropyron desertorum plants had been previously fertilized or shaded. All plants responded with increased root growth rates in N-enriched patches. However, root proliferation by shaded plants was 50% less than unshaded plants. Unexpectedly, plants with higher N status had greater root growth rates in enriched patches than plants that had not received N supplement. I concluded that plants already under competitive pressure above ground for light and below ground for nutrients …

Effects Of Douglas-Fir Foliage Age Class On Western Spruce Budworm Oviposition Choice And Larval Performance, Kimberly A. Dodds, Karen M. Clancy, Kathryn J. Leyva, David Greenberg, Peter W. Price

Great Basin Naturalist

The western spruce budworm (Choristoneura occidentalis Freeman) prefers to feed on flushing buds and current-year needles of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco). Budworm larvae will not typically consume older age classes of needles unless all current-year foliage is depleted. We tested the following null hypotheses: (1) budworm larvae can feed on foliage with a wide range of qualities (i.e., current 1-, 2-, or 3-year-old needles) without measurable effects on fitness; and (2) budworm adults do not show any oviposition preference linked to the age of the foliage they fed on as larvae. We used both laboratory and field …

Identification Of A Brazil-Nut Allergen In Transgenic Soybeans, Julie A. Nordlee, Steve L. Taylor, Jeffrey A. Townsend, Laurie A. Thomas, Robert K. Bush

Department of Food Science and Technology: Faculty Publications

Background: The nutritional quality of soybeans (Glycine max) is compromised by a relative deficiency of methionine in the protein fraction of the seeds. To improve the nutritional quality, methionine-rich 2S albumin from the Brazil nut (Bertholletia excelsa) has been introduced into transgenic soybeans. Since the Brazil nut is a known allergenic food, we assessed the allergenicity of the 2S albumin.

Methods: The ability of proteins in transgenic and nontransgenic soybeans, Brazil nuts, and purified 2S albumin to bind to IgE in serum from subjects allergic to Brazil nuts was determined by radioallergosorbent tests (four …
