Arkansas Soybean Performance Tests 2011, R. D. Bond, D. G. Dombek, J. A. Still, R. M. Pryor

Arkansas Agricultural Experiment Station Research Series

Soybean variety and strain performance tests are conducted each year in Arkansas by the University of Arkansas System Division of Agriculture Arkansas Crop Variety Improvement Program. The tests provide information to companies developing varieties and/or marketing seed within the state, and aid the Arkansas Cooperative Extension Service in formulating variety recommendations for soybean producers.

Assessing Biodegradable Containers For Growing Long-Term Greenhouse Crops In Subirrigation System, Stephanie A. Beeks

Graduate Theses and Dissertations

The objective for this research was to assess the efficacy of biodegradable containers compared to plastic containers for the production of long-term crops using a subirrigation system. Plastic and various biocontainers were used to grow `Rainier Purple' cyclamen (Cyclamen persicum L.) in ebb-and-flood benches. After 15 weeks, the physical properties of the containers were tested. The used plastic containers had strengths of 23.3, 23.5 and 21.9 g for the bottom, middle and top zones respectively. The peat, dairy manure and wood fiber containers had strengths of less than 2 kg for each zone. The peat, dairy manure, wood fiber and …

Western Tentiform Leafminer Phyllonorycter Elmaella, Diane G. Alston, Michael E. Reding

All Current Publications

Western tentiform leafminer populations can vary tremendously between years or even between generations within a single year. A large population in Utah's commercial fruit districts hasn't been observed since the early 2000s. Increasing resistance to organophosphate insecticides and variable effectiveness of at least six parasitic wasp species that attack the leafminer can influence the population size.

Arkansas Corn And Grain Sorghum Perfomance Tests 2011, R. D. Bond, D. G. Dombeck, J. A. Still

Arkansas Agricultural Experiment Station Research Series

Corn and grain sorghum performance tests are conducted each year in Arkansas by the University of Arkansas System Division of Agriculture. The tests provide information to companies marketing seed within the state and aid the Arkansas Cooperative Extension Service in formulating recommendations for producers.

Heritable Epigenetic Variation Among Maize Inbreds, Steve R. Eichten, Ruth A. Swanson, James C. Schnable, Amanda J. Waters, Peter J. Hermanson, Sanzhen Liu, Cheng-Ting Yeh, Yi Jia, Karla Gendler, Michael Freeling, Patrick S. Schnable, Matthew W. Vaughn, Nathan M. Springer

Department of Agronomy and Horticulture: Faculty Publications

Epigenetic variation describes heritable differences that are not attributable to changes in DNA sequence. There is the potential for pure epigenetic variation that occurs in the absence of any genetic change or for more complex situations that involve both genetic and epigenetic differences. Methylation of cytosine residues provides one mechanism for the inheritance of epigenetic information. A genome-wide profiling of DNA methylation in two different genotypes of Zea mays (ssp. mays), an organism with a complex genome of interspersed genes and repetitive elements, allowed the identification and characterization of examples of natural epigenetic variation. The distribution of DNA methylation …

Response Of Evergreen Perennial Tree Crops To Gibberellic Acid Is Crop Load-Dependent: Ii. Ga3 Increases Yield And Fruit Size Of ‘Hass’ Avocado Only In The On-Crop Year Of An Alternate Bearing Orchard, Lauren C. Garner, Grant Klein, Yusheng Zheng, Toan Khuong, Carol J. Lovatt

Horticulture and Crop Science

Despite problems of low fruit set, small fruit size and alternate bearing, the Hass cultivar dominates commercial avocado production worldwide. To increase yield and fruit size, gibberellic acid (GA₃) (25 mg L⁻¹) was applied at different stages of ‘Hass’ avocado tree phenology: (i) mid–late April (flower abscission), end of June–beginning of July (fruit abscission and beginning of the exponential phase of fruit growth), and mid-January (beginning of pre-harvest fruit drop); (ii) end of June–beginning of July; and (iii) mid-September (near the end of the major fruit abscission period; period of …

Identification And Thermochemical Analysis Of High-Lignin Feedstocks For Biofuel And Biochemical Production, Venugopal Mendu, Anne E. Harman-Ware, Mark Crocker, Jungho Jae, Jozsef Stork, Samuel Morton, Andrew Placido, George Huber, Seth Debolt

Horticulture Faculty Publications

BACKGROUND: Lignin is a highly abundant biopolymer synthesized by plants as a complex component of plant secondary cell walls. Efforts to utilize lignin-based bioproducts are needed.

RESULTS: Herein we identify and characterize the composition and pyrolytic deconstruction characteristics of high-lignin feedstocks. Feedstocks displaying the highest levels of lignin were identified as drupe endocarp biomass arising as agricultural waste from horticultural crops. By performing pyrolysis coupled to gas chromatography-mass spectrometry, we characterized lignin-derived deconstruction products from endocarp biomass and compared these with switchgrass. By comparing individual pyrolytic products, we document higher amounts of acetic acid, 1-hydroxy-2-propanone, acetone and furfural in switchgrass …

Sam Van Aken: New Edens, Shannon Egan

Schmucker Art Catalogs

Hybridized fruit trees, grafted orchids on shiny, reflective aluminum pedestals, fluorescent lights placed vertically on stands, and sheets of silver Mylar create a lush and somewhat disorienting space in contemporary artist Sam Van Aken’s most recent body of work New Edens. Van Aken makes Gettysburg College’s Schmucker Art Gallery into a kind of fantastical and futuristic winter garden. Without daylight and despite the cool fall weather of the Northeast, the dozen trees in the gallery are leafy and green, some even bearing fruit. Peach, plum, cherry, nectarine and apricot branches emerge from a single trunk and grow productively alongside their …

Miscanthus 3 Giganteus Productivity: The Effects Of Management In Different Environments, Matt Maughan, German Bollero, D.K. Lee, Robert Darmody, Stacy Bonos, Laura Cortese, James Murphy, Roch E. Gaussoin, Matthew Sousek, David Williams, Linda Williams, Fernando Miguez, Thomas Voigt

Department of Agronomy and Horticulture: Faculty Publications

Miscanthus 9 giganteus is a C4 perennial grass that shows great potential as a high-yielding biomass crop. Scant research has been published that reports M. 9 giganteus growth and biomass yields in different environments in the United States. This study investigated the establishment success, plant growth, and dry biomass yield of M. 9 giganteus during its first three seasons at four locations (Urbana, IL; Lexington, KY; Mead, NE; Adelphia, NJ) in the United States. Three nitrogen rates (0, 60, and 120 kg ha -1) were applied at each location each year. Good survival of M. 9 giganteus during its first …

Life History Of An Exotic Soft Scale Insect Phalacrococcus Howertoni (Hemiptera: Coccidae) Found In Florida, Kaushalya G. Amarasekare, Catharine M. Mannion

Agricultural and Environmental Sciences Faculty Research

We investigated the life history of an exotic soft scale insect, Phalacrococcus howertoni Hodges and Hodgson that damages croton and several other economically important ornamental and fruit plants in Florida. There was no difference in the development, survival, and reproduction of this scale insect species when reared either on croton or on buttonwood at 27 ± 1°C, 12:12 (L:D) h and 65% R. H. The scale insect practiced ovoviviparity. We observed that eggs that came out from vulva hatched to first instars immediately. Newly hatched nymphs had a tendency stay underneath the female body for somewhat less than approximately 24 …
