Escape From Preferential Retention Following Repeated Whole Genome Duplications In Plants, James C. Schnable, Xiaowu Wang, J. Chris Pires, Michael Freeling

Department of Agronomy and Horticulture: Faculty Publications

The well supported gene dosage hypothesis predicts that genes encoding proteins engaged in dose–sensitive interactions cannot be reduced back to single copies once all interacting partners are simultaneously duplicated in a whole genome duplication. The genomes of extant flowering plants are the result of many sequential rounds of whole genome duplication, yet the fraction of genomes devoted to encoding complex molecular machines does not increase as fast as expected through multiple rounds of whole genome duplications. Using parallel interspecies genomic comparisons in the grasses and crucifers, we demonstrate that genes retained as duplicates following a whole genome duplication have only …

Establishment Method And Cultural Practice Effects On Sports Turf, Josh Anderson

Graduate Theses and Dissertations

The use of soil-based sod on sand-based rootzones for the establishment of sports fields and golf courses is a common occurrence. Furthermore, the use of soil-based sod on sand-based rootzones can lead to potential problems associated with decreased water infiltration, gas exchange, rooting, and turfgrass quality caused by soil layering. Core-aerification and sand topdressing may help alleviate the problems associated with soil layering from the use of soil-based sod on sand-based rootzones. Therefore, the objectives of this research were to evaluate the effects of sod establishment methods and post- establishment cultural practices on the infiltration rate, moisture content, divot resistance, …

Sensor Based Irrigation Effects On Root Distribution And Growth Of Grafted And Non-Grafted Watermelons, Gilbert Miller

All Dissertations

ABSTRACT
Watermelon rooting patterns, root dry weight, plant biomass, stomatal resistance, root-to-shoot ratio, fruit yield, and fruit quality were evaluated in field trials during 2008, 2009 and 2010, using three irrigation regimes and three plant types. Plant types included: `Wrigley' grafted on Cucurbita moschata x Cucurbita maxima cv. Chilsung Shintoza; `Wrigley' grafted on Lagenaria siceraria cv. Fr Strong; and `Wrigley' not grafted. The irrigation regimes were: (1) No irrigation (NI) (30 minutes per day for fertigation only); (2) 50% and (3) 15% available water depletion (AWD) in the 0-30 cm soil profile triggered irrigation. Each whole plot contained a Sentek …

Optimizing Greenhouse Corn Production: How Can Two-Spotted Spider Mites Be Controlled?, Robert Eddy, Daniel T. Hahn

Purdue Methods for Corn Growth

This publication describes our experiences controlling mites while conducting experiments to optimize greenhouse corn production. Controlled studies were not conducted, but we recommend cultural practices of water spray-offs of leaf undersides and the stripping lower leaves as the crop ages. Also recommended are applications of beneficial insect Phytoseiulus persimilis at very high rates. The rates are an update of our previous publication. Photos of the pest and cultural practices are provided.

Optimizing Greenhouse Corn Production: What Is The Best Pot Size?, Derek Gambrel, Robert Eddy, Daniel T. Hahn

Purdue Methods for Corn Growth

This publication describes studies conducted to determine best pot size for optimizing greenhouse corn production. We suggest a 2.2-gallon container without large drainage holes extending up the side of the pot. This represents an update of our previous recommendation of a smaller pot, after observing instability in row planting configurations. Photos are included of corn in various size pots.

Sustainable Agriculture Undergraduate Degree Programs: A Land-Grant University Mission, Krista L. Jacobsen, Kim L. Niewolny, Michelle S. Schroeder-Moreno, Mark Van Horn, Alison H. Harmon, Yolanda H. Chen Fanslow, Mark A. Williams, Damian Parr

Horticulture Faculty Publications

There has been considerable growth in the number undergraduate degree programs in sustainable agriculture (SA) in universities and colleges across the country in the past 25 years. As a subset of this national trend, land-grant universities (LGUs) are emerging as catalysts in innovative SA program development, in part due to the LGU tripartite mission of education, extension, and research. This mission compels LGUs to develop undergraduate degree offerings to engage student, faculty, and community stakeholders who are increasingly interested in SA. In this article, which is an outcome of a gathering of faculty, staff and students from SA programs at …

Community Gardening: Benefits Focused Strategies, Joseph Zaanan Tellschow

UNLV Theses, Dissertations, Professional Papers, and Capstones

Throughout history humans have had varying degrees of interaction with nature and natural environments. This interaction has shaped our species in almost every way possible from our physical traits to our behaviors and places we have chosen to occupy. Currently, humans have developed such overwhelming mastery of the planet that it is easy for many humans to feel disconnected from nature. This separation could have detrimental effects on various aspects of human well-being including physical and mental health. To understand these effects, it is important to evaluate the benefits that humans receive from exposure to nature and interaction with natural …

Processing Quality Of Potato Tubers Produced During Autumn And Spring And Stored At Different Temperatures, Sergio T. De Freitas, Engil Isadora Pujol Pereira, Ana Cecilia S. Gomez, Auri Brackmann, Fernando Nicoloso, Dilson A. Bisognin

School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

The objective of this work was to access processing quality of potato clones (Solanum tuberosum) Asterix, SMINIA793101-3, and Missaukee cultivated during spring and autumn growing seasons and stored at 4, 8, 12, or 25ºC. Clones grown in spring had shorter dormancy than clones grown in autumn. Potato tubers grown in spring and autumn and stored at 4ºC, as well as tubers grown in autumn and stored at 8ºC had no sprouting for six months. Among clones grown in autumn, the longest dormancy period during storage at 12ºC was observed in the clone SMINIA793101-3, and at 25ºC was in the clone …

Sugar-Enhanced Sweet Corn Cultivar Evaluation For Northern Indiana, 2011, Elizabeth Maynard

Purdue Fruit and Vegetable Research Reports
