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.

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 1,000 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 …

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. …

Supersweet Sweet Corn Cultivar Evaluation For Northern Indiana, 2010, Elizabeth T. Maynard

Purdue Fruit and Vegetable Research Reports

Indiana growers harvested sweet corn for fresh market sales from 6,100 acres in 2009, with an average yield of 69 cwt/acre (164 crates or 3.45 tons per acre) and total value of $16.8 million (USDA NASS,2010). Indiana ranks 14th among states for production of fresh market sweet corn. The 2007 USDA Ag Census reported 603 Indiana farms producing sweet corn for fresh markets and 51 farms selling to processors. Sweet corn fields for fresh market sales are located throughout the state. In northern Indiana, bi-color corn is most commonly grown. Varieties with improved eating quality are of interest to both …

Response Of Warm Season Turfgrasses To Reduced Light Environments, Jeffrey Atkinson

All Theses

Shade or low light tolerance is an increasingly important issue to turf managers as they are often expected to grow turf in less than ideal agronomic conditions. As permanent structures such as residential buildings add to already problematic shade caused by trees, and other barriers, new solutions are needed to help turf managers provide acceptable turf conditions. The plant growth regulator trinexapac-ethyl (TE) can lessen negative responses of turfgrass to shade.
Two experiments were conducted during the summers of 2008 and 2009 to evaluate various grasses under a reduced light environment (RLE). In the first study, performance of `Diamond' zoysiagrass …

Selecting And Propagating Clones Of Bigtooth Maple (Acer Grandidentatum Nutt.), Melody Reed Richards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Numerous wild bigtooth maple (Acer grandidentatum Nutt.) specimens in northern Utah have potential for use in landscapes, but improvements in selection and propagation need to be developed before these specimens can be introduced to the green industry. Criteria-based evaluations centered on aesthetics, function, and fall color were performed to objectively select superior bigtooth maple specimens. Out of 56 trees initially selected for red fall color, six were selected for propagation based on all three criteria. Five of the six selected trees yielded viable bud take via chip budding. Optimum time for chip budding propagation was determined by four experiments. …

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.

Enhancing Out-Of-Season Production Of Tomatoes And Lettuce Using High Tunnels, Britney L. Hunter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The growing season for vegetable crops is limited by freezing temperatures in arid high elevation climates such as northern Utah. Logan, Utah (41.73 N, 111.83 W, 1382 m elevation) has a short, variable growing season with an average frost-free period of 135 days. Extending the growing season provides growers with an opportunity to extend revenue into a normally unproductive period and benefit from out-of-season price premiums. High tunnels have been used to effectively extend the growing season for numerous crops by providing cold temperature protection. However, limited high tunnel research has been performed in arid high elevation regions that experience …

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 …
