Experimental Wine Making, Murli R. Dharmadhikari, Sebastian Donner, Jennifer Hansen 2010 Iowa State University

Experimental Wine Making, Murli R. Dharmadhikari, Sebastian Donner, Jennifer Hansen

Iowa State Research Farm Progress Reports

The substantial growth of the Iowa grape and wine industry over the past decade resulted in the establishment of the Midwest Grape and Wine Industry Institute to investigate various cold climate grape cultivars and their potential for wine making. Unfortunately, due to the climate encountered in Iowa, we are not able to simply adopt wine making practices used in other parts of the world to achieve the best quality wines possible for our region. The project described herein focused on the production of small batches of experimental wine to evaluate cold climate cultivars and the impact of conditions on the ...

Location Choices Of Ethanol Firms In The Midwest Corn Belt, Monica A. Haddad, Gary Taylor, Francis Y. Owusu 2010 Iowa State University

Location Choices Of Ethanol Firms In The Midwest Corn Belt, Monica A. Haddad, Gary Taylor, Francis Y. Owusu

Community and Regional Planning Publications

The Corn Belt has experienced a rapid expansion of corn-based ethanol plants. This has provided researchers the opportunity to examine the relative importance to the renewable fuels industry of several location factors previously identified as important to agro-industries. Using probit regression this study identifies the factors significant to ethanol firms’ location decisions in the four-state study area of Iowa, Illinois, Minnesota and Nebraska. In Iowa and Illinois, where corn is largely ubiquitous, firms move beyond corn supply to consider other localized factors in their decisionmaking process. Factors such as rail access, population density and proximity to blending terminals emerge as ...

La Producción De Las Fresas Utilizando El Túnel Alto, Daniel Rowley, Brent Black, Dan Drost

All Current Publications

Las fresas locales y frescas son siempre un favorito en los mercados de productores y en los puestos ambulantes. Las fresas crecen mejor en las temperaturas alrededor de 70 a 75˚ F (21 a 24˚ C). Los inviernos fríos y los veranos calientes solo dejan una temporada de fresas muy corta. Se diseñan los invernaderos para mantener temperaturas óptimas para el crecimiento y se las puede usar para cultivar las fresas durante todo el año. Sin embargo, los invernaderos son muy costosos para construir y operar. Los túneles altos son relativamente baratos para construir, con algunos diseños costando menos de ...

Soil As A History Book, Bradley Allen Miller 2010 Iowa State University

Soil As A History Book, Bradley Allen Miller

Agronomy Publications

Soil is one of the most influential components of our enviroronment. It is a complex mixture of physical, chemical, and biological processes providing innumerable ecosystem services. The properties of our soil today support our way of life. It filters our water, contains our wastes, and is the substrate for the production of our food. Combined with a good climate, the convergence of the right soil properties here in Iowa has given its citizens the opportunity to be net exporters of food and feed. That opportunity gives Iowans the ability to feed themselves and prosper economically through the sale of excess ...


Quantitative Trait Loci For Endosperm Modification And Amino Acid Contents In Quality Protein Maize, Andrés Gutiérrez-Rojas, Javier Betrán, M. Paul Scott, Halima Atta, Mónica Menz 2010 Texas A & M University - College Station

Quantitative Trait Loci For Endosperm Modification And Amino Acid Contents In Quality Protein Maize, Andrés Gutiérrez-Rojas, Javier Betrán, M. Paul Scott, Halima Atta, Mónica Menz

Agronomy Publications

The deficient protein quality of corn (Zea mays L.) grain can be improved by replacing normal Opaque2 (O2) alleles with nonfunctional mutant o2 alleles. Unfortunately, o2 alleles are associated with soft endosperm texture, poor yield, and susceptibility to diseases and insects. Plant breeders have been able to restore a desirable ratio of hard to soft endosperm in o2germplasm. These modified genotypes are known as Quality Protein Maize (QPM). Neither the mechanism nor the genetic components controlling endosperm modification in QPM lines are well understood. Using a population of recombinant inbred lines, derived from a cross between an o2 line ...

Genetic Diversity, Micro Propagation, And Cold Hardiness Of Ilex Glabra (L.) A. Gray, Youping Sun

Electronic Theses and Dissertations

Ilex glabra (L.) A.Gray (inkberry) is a native evergreen shrub with dark green foliage and compact habit. This shrub has gained popularity in the northern landscapes of the United States and more nursery growers would like to produce it. To better understand genetic relationships among inkberry cultivars and breed cold-hardy cultivars for northern nursery growers and landscape specialists, the following projects were conducted. A group of 48 inkberry accessions and two other Ilex species (Ilex crenata Thunb. and I. mutchagara Makino) were studied using amplified fragment length polymorphism (AFLP) markers. A total of 229 markers between 50 and 500 ...

Publications from USDA-ARS / UNL Faculty

Transplantation of male germ line cells into sterilized recipients has been used in mammals for conventional breeding as well as for transgenesis. We have previously adapted this approach for the domestic chicken and we present now an improvement of the germ cell transplantation technique by using an enriched subpopulation of c-Kit-positive spermatogonia as donor cells. Dispersed c-Kit positive testicular cells from 16 to 17 week-old pubertal donors were transplanted by injection directly into the testes of recipient males sterilized by repeated gamma irradiation. We describe the repopulation of the recipient’s testes with c-Kit positive donor testicular cells, which resulted ...

Moffet, Bruce A. Roundy, Thomas A. Jones, Stephen J. Novak, Patrick E. Clark, Frederick B. Pierson, Gerald N. Flerchinger

Publications from USDA-ARS / UNL Faculty

Cheatgrass (Bromus tectorum L.) has come to dominate millions of hectares of rangeland in the Intermountain western United States. Previous studies have hypothesized that one mechanism conferring a competitive advantage to this species is the ability to germinate rapidly at low temperatures in the fall, winter and spring and, therefore, initiate growth and establishment more rapidly than more desirable perennial bunchgrass species. In this experiment, we developed thermal-germination-response models for multiple seedlots of cheatgrass and five perennial grass species. We conducted sensitivity analysis on potential-cumulative-germination response to a 38-year simulation of field-variable conditions of seedbed temperature and moisture. Cheatgrass uniformly ...

Estimation Of Effective Plant Area Index For South Korean Forests Using Lidar System, D. A. Kwak, W. K. Lee, Menas Kafatos, Y. Son, H. K. Cho, S. H. Lee

Mathematics, Physics, and Computer Science Faculty Articles and Research

Light Detection and Ranging (LiDAR) systems can be used to estimate both vertical and horizontal forest structure. Woody components, the leaves of trees and the understory can be described with high precision, using geo-registered 3D-points. Based on this concept, the Effective Plant Area Indices (PAIe) for areas of Korean Pine (Pinus koraiensis), Japanese Larch (Larix leptolepis) and Oak (Quercus spp.) were estimated by calculating the ratio of intercepted and incident LIDAR laser rays for the canopies of the three forest types. Initially, the canopy gap fraction (GLiDAR) was generated by extracting the LiDAR data reflected from the canopy surface, or ...

Ethylene Receptors Function As Components Of High-Molecular-Mass Protein Complexes In Arabidopsis, Brad Binder, Yi-Feng Chen, Zhiyong Gao, Robert Kerris, Wuyi Wang, G. Schaller 2009 University of Tennessee - Knoxville

Ethylene Receptors Function As Components Of High-Molecular-Mass Protein Complexes In Arabidopsis, Brad Binder, Yi-Feng Chen, Zhiyong Gao, Robert Kerris, Wuyi Wang, G. Schaller

Brad M. Binder

Background The gaseous plant hormone ethylene is perceived in Arabidopsis thaliana by a five-member receptor family composed of ETR1, ERS1, ETR2, ERS2, and EIN4. Methodology/Principal Findings Gel-filtration analysis of ethylene receptors solubilized from Arabidopsis membranes demonstrates that the receptors exist as components of high-molecular-mass protein complexes. The ERS1 protein complex exhibits an ethylene-induced change in size consistent with ligand-mediated nucleation of protein-protein interactions. Deletion analysis supports the participation of multiple domains from ETR1 in formation of the protein complex, and also demonstrates that targeting to and retention of ETR1 at the endoplasmic reticulum only requires the first 147 amino ...

A field survey was conducted in 2007 to characterize weed populations in different turfgrass sites throughout the Klang Valley of western Peninsular Malaysia. Sites included golf course putting greens, athletic fields, sod farms, and residential lawns. Weeds present in each site were identified and the data were used to calculate frequency, distribution uniformity, density, relative abundance, and community coefficient values for each species. Seventy-nine weed species, belonging to 16 families, were found. The most species were found on residential lawns, and the fewest were found on golf course putting greens; athletic fields and sod farms ranked intermediately. A total of ...

Expression Profiling Of Crambe Abyssinica Under Arsenate Stress Identifies Genes And Gene Networks Involved In Arsenic Metabolism And Detoxification, Om Parkash, Suganthi Kandasamy, Bibin Paulose

Om Parkash

Background Arsenic contamination is widespread throughout the world and this toxic metalloid is known to cause cancers of organs such as liver, kidney, skin, and lung in human. In spite of a recent surge in arsenic related studies, we are still far from a comprehensive understanding of arsenic uptake, detoxification, and sequestration in plants. Crambe abyssinica, commonly known as 'abyssinian mustard', is a non-food, high biomass oil seed crop that is naturally tolerant to heavy metals. Moreover, it accumulates significantly higher levels of arsenic as compared to other species of the Brassicaceae family. Thus, C. abyssinica has great potential to ...
