Styrax americanus Lam. (American snowbell) is an ornamental tree or shrub seldom used in the nursery industry. The species is common in the southeastern United States and is distributed continuously as far north as southeastern Virginia and southern Illinois. We studied a small, threatened population in northern Illinois (latitude = 41y10N), about 500 km disjunct from populations to the south. Little is known about the genetic diversity and landscape potential of this species. The first objective was to evaluate the genetic structure of the northern disjunct population and compare those individuals genetically to populations from the northern and southern extremes of ...


Evaluation Of Popping Expansion Traits In A Maize (Zea Mays L.) Population, Mauricio Erazo-Barradas Jan 2009

Evaluation Of Popping Expansion Traits In A Maize (Zea Mays L.) Population, Mauricio Erazo-Barradas

Graduate Theses and Dissertations

In a popcorn breeding program, the procedures and techniques used for breeding popcorn are similar to those used for breeding dent corn with some minor adjustments needed. The adjustments in popcorn breeding are due to the poorer agronomic traits performance of popcorn germplasm compared with dent corn germplasm. The reasons for the poorer agronomic traits of popcorn are: the limited effort focused on improvement of popcorn, agronomic traits of popcorn are not the most important traits emphasized in selection, and the base germplasm available for popcorn breeding program does not perform agronomically as well as the base dent corn germplasm ...

The present work addresses fundamental and practical considerations of using maize for production of recombinant proteins. Maize expressing the B subunit of the heat labile enterotoxin (LT-B) of Escherichia coli was used as a model crop. To address the fundamental aspects of the system, the role of LT-B and its native signal peptide (BSP) in plant cells was investigated using translational fusions with the green fluorescent protein. Confocal microscopy showed that fusions carrying BSP or a maize 27 kD γ-zein signal peptide (ZSP) accumulated in the secretory system of Arabidopsis and maize. Fusions lacking a signal peptide accumulated in the ...


Fossil Energy Use In Conventional And Low-External-Input Cropping Systems, Michael James Cruse Jan 2009

Fossil Energy Use In Conventional And Low-External-Input Cropping Systems, Michael James Cruse

Graduate Theses and Dissertations

The production of fossil fuels will crest within the next decade and with reliance of modern conventional agriculture on fossil fuel energy inputs, food production will be stressed. Modern production practices also have negative impacts on the environment, but it is well established that the ecological impact of conventional agriculture can be reduced by utilizing alternative agricultural practices. Conservation tillage practices and diverse crop rotations reduce the need for fossil fuel energy inputs while maintaining high crop yields. An ongoing field experiment in the Central Corn Belt compares viable alternative systems to conventional corn-soybean rotations. The alternative systems, referred to ...

Seeding Rates Of Annual Ryegrass That Maximize Turf Cover When Sown During Traffic, Andrew Hansen Hoiberg

Graduate Theses and Dissertations

Exceeding normal seeding rates when establishing turf cover in worn areas of cool-season athletic fields is a common practice. Maximum sowing rates during traffic have not been determined for annual ryegrass (Lolium multiflorum Lam.). Our objective was to determine the seeding rate ceiling and seeding schedule that maximizes turf cover when sowing annual ryegrass during traffic. Improved varieties of annual ryegrass are expanding its potential applications. One such variety, 'Panterra' annual ryegrass was established at the Horticulture Research Farm in Ames, Iowa USA, on 4 Sept 2006 and 3 Sept 2007 into two separate study areas, bare soil and killed ...


Soil Sample Handling For Routine Analysis Of Plant-Available Soil Potassium, Brian Edward Hill Jan 2009

Soil Sample Handling For Routine Analysis Of Plant-Available Soil Potassium, Brian Edward Hill

Graduate Theses and Dissertations

Soil K extraction with neutral 1 M ammonium-acetate (NH4OAc) based on air-dried or oven-dried samples is the most widely used soil test for K. It has long been recognized that sample drying often increases K extracted by this test. An NH4OAc K test based on field-moist samples (MK) was used until 1988 by the Iowa State University laboratory but was abandoned because no private laboratory adopted it. In the 1960's work was done to look at different chemical treatments that prevent K from being released upon sample drying or revert the drying effect before K ...

Chenopodium album is a widespread and troublesome weed in Iowa and agricultural areas throughout the north temperate regions of the world. This study investigated the effects of various factors on the stimulation of germination of two populations of C. album seeds collected in 2007 and 2008 at a common location. These factors included light, temperature, after-ripening time, nitrate, and water level. Germination of both populations was generally stimulated by light, warm (15-25yC) and hot (25-35yC) temperatures, 0.01 M nitrate, 3 to 5 weeks of after-ripening (4yC, dark, moist), and with the 2008 population, 1.0 and 1.25 ml ...


Quaternary Stratigraphy And Pedology Of Clear Creek Watershed In Iowa County, Iowa, Brad Oneal Jan 2009

Quaternary Stratigraphy And Pedology Of Clear Creek Watershed In Iowa County, Iowa, Brad Oneal

Graduate Theses and Dissertations

Several studies have described the stratigraphy of loess derived soils throughout the state of Iowa and surrounding states in the Midwest. However, the stratigraphy of loess derived soils in the eastern portion of the state of Iowa has never thoroughly been investigated. This study investigated the Clear Creek watershed in eastern Iowa using a classical soil-stratigraphy approach of deep coring along hillslope transects coupled with extensive solum deep sampling in specific areas of interest. A catena-stratigraphy approach was used to not only look at soil properties at depth, but also compare them between different hillslope positions. Dynamic soil properties including ...

Freezing Tolerance And Dehydrin Protein Expression In `Frontenac' And `Seyval Blanc' Grapevine Bark And Xylem Cane Tissues During Acclimation, Midwinter, And Deacclimation, Lee Huntington Trebbien Goldsmith

Graduate Theses and Dissertations

Although the cold hardiness of primary buds has been examined for grape cultivars and is used as a principle factor of grapevine cold hardiness, freezing tolerance capacity in the rest of the vine has received relatively little attention. This investigation characterized freezing tolerance and protein expression of `Frontenac' and `Seyval blanc' grape cane tissues during the overwintering periods of autumnal cold acclimation, midwinter, and vernal deacclimation including dehydrin proteins that may be used to describe cultivar freezing tolerance. Controlled, laboratory freezing tests were conducted with field acclimated or deacclimated bark and xylem tissues from grape canes. SDS-PAGE profiles and immunoblots ...


On-Farm Evaluation Of Fluid Starter Potassium Fertilization For Corn Using Precision Agriculture Technologies, Nicolas Bergmann Jan 2009

On-Farm Evaluation Of Fluid Starter Potassium Fertilization For Corn Using Precision Agriculture Technologies, Nicolas Bergmann

Graduate Theses and Dissertations

Use of fluid N–P or N–P–K starter mixtures in most research studies precludes firm conclusions about specific starter K effects on early crop growth and grain yield. This study evaluated corn (Zea mays L.) early growth, early plant K concentration and uptake, and grain yield response to fluid starter K fertilizer. Eight trials were conducted during 2007 and 2008 in Iowa farmers’ fields using a strip trial methodology, global positioning systems, yield monitors, and geographical information systems. Six sites were managed with chisel–plow tillage and two with no–tillage. Soil–test K (STK) was measured using ...

Horticultural Potential And Population Genetics Of Nyssa Aquatica L. (Water Tupelo), Nickolee Zollinger Boyer

Graduate Theses and Dissertations

Trees native to seasonally flooded wetlands can be valuable in managed landscapes where wide fluctuations in soil moisture occur regularly. Nyssa aquatica L. (water tupelo) is a large, deciduous tree native to continuously and periodically flooded wetlands of the southeastern United States. I investigated the potential for using this tree in horticulture based on its tolerance to extreme fluctuations in soil moisture, water deficit, and its capability to be propagated asexually via stem cuttings. I also examined the genetic structure of the species across its native range by using inter-simple sequence repeats (ISSRs). Seedlings of N. aquatica were more tolerant ...


Evaluation Fo Frost Damage In Seed Corn (Zea Mays): With Special Emphasis On Seed Composition And Moisture Content, Heather Ann Hall Jan 2009

Evaluation Fo Frost Damage In Seed Corn (Zea Mays): With Special Emphasis On Seed Composition And Moisture Content, Heather Ann Hall

Graduate Theses and Dissertations

Fall frost is a serious concern to seed corn (Zea mays L.) producers in the Midwest. A frost event that happens prior to seed maturity can cause physical, biochemical, and physiological changes in the seed. These changes lead to decreased vigor and viability resulting in revenue loss for seed corn producers. Genetics and seed maturity greatly influence seed tolerance to frost damage. The central hypothesis of this study is that differences in frost tolerance can occur among the same genotype and these differences may be the result of varying seed oil and protein contents. Information gathered from this study may ...


Photoprotective Strategies In Overwintering Rhododendrons, Xiang Wang Jan 2009

Photoprotective Strategies In Overwintering Rhododendrons, Xiang Wang

Graduate Theses and Dissertations

Two Rhododendron species (R. catawbiense and R. ponticum) are used to study their different photoprotective strategies during seasonal cold acclimation at morphological, anatomical, physiological, biochemical and molecular levels. In addition, this dissertation also studied whether or not RcPIP2s (R. catawbiense PIP2s) expression patterns were associated with thermonastic leaf curling in rhododendrons.

Microscopic data revealed that the two Rhododendron species evolved distinct leaf anatomy which could have potential adaptive significance to high light at subfreezing temperatures (chapter 2). Compared with R. catawbiense, R. ponticum has significantly thicker leaf blades but thinner cuticles. There is one layer of upper epidermis and three ...


Quantifying And Predicting Interseeded Legume Establishment In Winter Cereals, Brock Cameron Blaser Jan 2009

Quantifying And Predicting Interseeded Legume Establishment In Winter Cereals, Brock Cameron Blaser

Graduate Theses and Dissertations

Interseeding red clover (Trifolium pratense L.) or alfalfa (Medicago sativa L.) into winter cereals in the North Central USA can provide forage and a green manure crop. We hypothesize that winter cereal canopy traits such as leaf area index (LAI) and whole plant dry matter (DM) influence interseeded legume establishment and productivity, yet the effect of canopy traits on resource competition in interseeded systems is not well understood. This study was conducted from 2005 to 2007 to evaluate the impact of diverse cereal canopy traits on the establishment of frost-seeded legume intercrops. In March, red clover and alfalfa were frost-seeded ...


Physiological Bases Of Environmental And Genotypic Effects On Soybean Seed Composition, Josy Luis Rotundo Jan 2009

Physiological Bases Of Environmental And Genotypic Effects On Soybean Seed Composition, Josy Luis Rotundo

Graduate Theses and Dissertations

Seed composition is an important determinant of soybean marketing value. Final seed composition is influenced by genotype and environment during seed filling. Variation in protein or oil concentration may determine years or locations with deficits in soybean oil or meal yield. A general model of environmental effects on seed composition to predict regions and/or environmental conditions that produce consistently high quality soybeans is needed. One way to reduce environmental chances of protein deficits is to use high protein varieties. However, breeding for high protein concentration has been hindered by negative correlations with yield and oil. Discovering the physiological bases ...

Use Of Seed Treatments And Inoculants In No-Tillage Soybean Production Practices, Joseph John Osenga

Graduate Theses and Dissertations

Soybean producers using no-tillage practices in the Upper Midwest encounter cooler, wetter soil conditions early in the growing season that slow crop growth and favor damping-off pathogens. The goal of this thesis work was to evaluate the use of soybean seed treatments and inoculants in no-tillage compared to conventional tillage practices in Iowa. The research reported in this thesis is divided into three specific objectives. The first objective was to evaluate the use of soybean seed treatments and inoculants in no-tillage and conventional tillage across Iowa. It was concluded that there was no evidence that the use of seed treatments ...


Horticultural Evaluation Of Zein-Based Bioplastic Containers, Matthew Steven Helgeson Jan 2009

Horticultural Evaluation Of Zein-Based Bioplastic Containers, Matthew Steven Helgeson

Graduate Theses and Dissertations

Environmental problems caused by petroleum-based plastics have led to interest in alternatives made from biodegradable polymers (bioplastics), but little effort has been made to evaluate horticultural containers made from these materials. Containers were fabricated from polymers of the corn (Zea mays L.) protein, zein. My first objective was to determine the longevity of zein-based containers under conditions typical of horticultural production. Zein containers of two wall thicknesses were filled with either a peat-based, soilless potting substrate or coarse perlite, and they were irrigated every 2 or 4 days. After 10 weeks, weight loss of containers was determined as a measure ...


Prediction Of Cultivar Performance And Heterogeneity Of Genotype Variance, Correlation And Error Variance In The Iowa Crop Performance Tests−Corn (Zea Mays L.), Yoon-Sup So Jan 2009

Prediction Of Cultivar Performance And Heterogeneity Of Genotype Variance, Correlation And Error Variance In The Iowa Crop Performance Tests−Corn (Zea Mays L.), Yoon-Sup So

Graduate Theses and Dissertations

Multi-environment trials generally have highly unbalanced data structures in which a particular cultivar is only observed in a subset of all environments for which data are available. A very common approach to reporting data from such unbalanced data is to subset the data into balanced sets and restrict comparisons within balanced sets. Such an approach results in much information being ignored. In an attempt to make use of all available information, a likelihood-based mixed linear model approach can be chosen since unbalanced data can be analyzed in a straightforward manner. Two studies were undertaken to determine the complexity of heterogeneity ...


The Role Of Capitals In The Promotion Of Sustainable Community Microfinance Organizations, Ignacio Carranza Cerda Jan 2009

The Role Of Capitals In The Promotion Of Sustainable Community Microfinance Organizations, Ignacio Carranza Cerda

Graduate Theses and Dissertations

In the Central Valleys of Puebla Mexico a rural microfinance scheme called "savings box" (caja de ahorros) has been established to promote sustainable development among rural small-holders. After ten years of operation of this microfinance community scheme there is little information on the differing performance of groups and factors that influence their survival in rural communities. The study was designed to elucidate how rural microfinance is related to social, human, cultural and financial capitals as indicators of survival and sustainability of the savings and loan groups. A cross-sectional study among 34 informal microfinance groups was conducted through interviews with representatives ...
