Solutions To Soil Problems: Ii. High Ph (Alkaline Soil), Loralie Cox, Rich Koenig

All Current Publications

PH is a measure of the acidity or alkalinity of a material. The pH scale ranges from 0 to 14, with 7 being neutral. A pH value below 7 indicates the soil is acidic, while values above 7 are alkaline. Each unit change in the pH scale is a 10-fold difference in acidity or alkalinity. For example, soil with a pH of 8 is ten times more alkaline than soil with a pH of 7.

Micropropagation And Acclimatization Of 'Norton' Grapevine (Vitis Aestivalis), Brant B. Bigger

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Propagation of the Vitis aestivalis cultivar 'Norton‘ (syn='Cynthiana‘) through traditional woody cuttings has been difficult. Rooting of woody cuttings has been a major hindrance in propagating this cultivar and providing enough plants to meet grower needs. In vitro propagation offers another method of increasing plant material. Cultures were established and maintained on Murashige and Skoog (MS) medium supplemented with 4 M 6-benzyladenine (BA) and thiamine at 0.5 mg•L^-1 and solidified with Difco-Bacto agar at 7.5 g•L^-1. The objectives of this study were to determine optimal methods for in vitro production and ex vitro establishment of 'Norton‘ plantlets. …

Delaying Bud Break In ‘Edelweiss’ Grapevines To Avoid Spring Frost Injury By Naa And Vegetable Oil Applications, Issam M. Qrunfleh

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Delaying bud break is an approach to avoid spring frost damage. Field experiments were conducted during the winters of 2009 and 2010 at James Arthur Vineyards in Raymond, Nebraska to study the effect of spraying NAA and Amigo Oil on delaying bud break in ‘Edelweiss’ grapevines to avoid such damage. In 2009, the experiment consisted of five treatments: NAA (500, 750, and 1000 mg/l), oil applied at 10%, and the non-sprayed control. There were four application dates: January 6, February 3, March 3, and April 1. Bud break was evaluated throughout spring. During harvest, the number of clusters and weights …

Utah Fertilizer Guide, D. W. James, K. F. Topper

All Current Publications

The Utah Fertilizer Guide is designed to provide practical answers to routine questions related to soil fertility management. The guide emphasizes laboratory analysis of soil and plant samples as the keystone to optimum fertilizer rates for maximum economic plant yield and quality. The focus of the guide is on soil fertility problems peculiar to the semi-arid and arid soils of Utah.

Solutions To Soil Problems: I. High Salinity (Soluble Salts), Vernon Parent, Rich Koenig

All Current Publications

Salinity is a measure of the total amount of soluble salts in soil. As soluble salt levels increase, it becomes more difficult for plants to extract water from soil. Some plants are more resistant than other’s, but as the salt levels exceed their ability to extract water, they become water stressed.

All Current Publications

Soil structure refers to the combination of primary soil particles – sand, silt and clay – into larger units called aggregates or clods. Aggregates are commonly seen when a soil is tilled or disturbed.

Solutions To Soil Problems: V. Low Organic Matter, Kevin Heaton, Rich Koenig

All Current Publications

Utah soils are inherently low in organic matter due to the desert climate and historically low plant growth rates. In Utah, soil organic matter levels are typically 0.25 to 1%, while regions with high rainfall such as the Midwest and Eastern United States have soils with as much as 7 to 10% organic matter.

Substrates Of The Arabidopsis Thaliana Protein Isoaspartyl Methyltransferase 1 Identified Using Phage Display And Biopanning, Tingsu Chen, Nihar Nayak, Susmita Maitra Majee, Jonathan Lowenson, Kim R. Schäfermeyer, Alyssa C. Eliopoulos, Taylor D. Lloyd, Randy Dinkins, Sharyn E. Perry, Nancy R. Forsthoefel, Steven G. Clarke, Daniel M. Vernon, Zhaohui Sunny Zhou, Tomas Rejtar, A. Bruce Downie

Horticulture Faculty Publications

The role of protein isoaspartyl methyltransferase (PIMT) in repairing a wide assortment of damaged proteins in a host of organisms has been inferred from the affinity of the enzyme for isoaspartyl residues in a plethora of amino acid contexts. The identification of PIMT target proteins in plant seeds, where the enzyme is highly active and proteome long-lived, has been hindered by large amounts of isoaspartate-containing storage proteins. Mature seed phage display libraries circumvented this problem. Inclusion of the PIMT co-substrate, S-adenosylmethionine (AdoMet), during panning permitted PIMT to retain aged phage in greater numbers than controls lacking co-substrate or when …

Host Instar Susceptibility And Selection And Interspecific Competition Of Three Introduced Parasitoids Of The Mealybug Paracoccus Marginatus (Hemiptera: Pseudococcidae), Kaushalya G. Amarasekare, Catharine M. Mannion, Nancy D. Epsky

Agricultural and Environmental Sciences Faculty Research

Three previously introduced parasitoids (Acerophagus papayae Noyes and Schauff, Anagyrus loecki Noyes and Menezes, and Pseudleptomastix mexicana Noyes and Schauff [Hymenoptera: Encyrtidae]) of the mealybug Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae) were studied for their host instar susceptibility and sex ratio, host instar selection, and interspecific competition in the laboratory. All three parasitoids were able to develop in the second instars, third-instar females, and adult females of P. marginatus. No progeny emerged from first-instar mealybugs. The proportion of female emergence was increased with increasing host size. Parasitoids selected their host instars for oviposition when they …

Relative Effectiveness Of Repellents For Preventing Deer Damage To Japanese Yews, Paul D. Curtis, Jason R. Boulanger

Biology Faculty Publications

Homeowners whose landscape plants are repeatedly browsed by white-tailed deer (Odocoileus virginianus) are interested in repellent products that are effective and long-lasting. New products come to market with limited experimental testing. We conducted a 10-week trial from Feb. through Apr. 1999 to test the duration and efficacy of six commercial deer repellents [Deer-Away Big Game Repellent (BGR) mix, BGR spray, Deer-Off, Deer Stopper II, Repellex, Tree Guard] and two experimental deer repellents (CU-A and CU-B) relative to each other and to untreated plants. Treated and control balled japanese yew (Taxus cuspidata) shrubs were placed at each …

Following Tetraploidy In Maize, A Short Deletion Mechanism Removed Genes Preferentially From One Of The Two Homeologs, Margaret R. Woodhouse, James C. Schnable, Brent S. Pedersen, Eric Lyons, Damon Lisch, Shabarinath Subramaniam, Michael Freeling

Department of Agronomy and Horticulture: Faculty Publications

Previous work in Arabidopsis showed that after an ancient tetraploidy event, genes were preferentially removed from one of the two homeologs, a process known as fractionation. The mechanism of fractionation is unknown. We sought to determine whether such preferential, or biased, fractionation exists in maize and, if so, whether a specific mechanism could be implicated in this process. We studied the process of fractionation using two recently sequenced grass species: sorghum and maize. The maize lineage has experienced a tetraploidy since its divergence from sorghum approximately 12 million years ago, and fragments of many knocked-out genes retain enough sequence similarity …

Good Agricultural Practices For Food Safety Of Fresh Produce, Laurie Hodges

Department of Agronomy and Horticulture: Faculty Publications

What are the guiding principles of food safety for fresh produce?

• Once contaminated, removing or killing pathogens on produce is very difficult.

• Preventing microbial contamination at all steps, from production to distribution, is strongly favored over treatments to eliminate contamination that may have occurred.

• Document the implementation of prevention programs, and educate workers at all levels of the agricultural and packing environments on food safety.

Key Signatures of a Credible Food Safety Program

The following is a condensed checklist of practices and conditions that reduce the potential for fresh produce to be exposed to pathogenic microbes. Review …
