Winter Greenhouse Production And Tissue Culture Of Basil (Ocimum Spp.), Wan Wei 2016 University of Nebraska-Lincoln

Winter Greenhouse Production And Tissue Culture Of Basil (Ocimum Spp.), Wan Wei

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Basil (Ocimum spp.) is a popular annual culinary and medicinal herb contains essential oils. Numerous researchers have studied the effects of fertilizer level on the growth and oil yield of basil, but in most studies, basil was grown in the field during the summer. Our experiment was conducted in a controlled environment greenhouse using a capillary mat system during the winter with a goal of increasing dry weight for fresh produce and basil essential oil. The 7-month experiment was conducted to determine the optimal production timeline and fertilizer levels for eight basil cultivars grown in a soilless mix. We found ...


Anaerobic Soil Disinfestation: Meta-Analysis And Optimization Of Amendment Carbon Rate And C:N Ratio To Control Key Plant Pathogens And Weeds, Utsala Shrestha 2016 University of Tennessee, Knoxville

Anaerobic Soil Disinfestation: Meta-Analysis And Optimization Of Amendment Carbon Rate And C:N Ratio To Control Key Plant Pathogens And Weeds, Utsala Shrestha

Doctoral Dissertations

Anaerobic soil disinfestation (ASD) is an environmentally friendly and cost effective pre-plant soil treatment technique that allows effective control of soilborne pests by creating anaerobic conditions, particularly for specialty and organic crop production under diverse environmental conditions. In spite of being a proven technique, ASD has to be optimized to fit into local production systems with specific pathogen pressure using locally available amendments for successful implementation on a commercial scale. Our meta-analysis study on soilborne pathogens, plant parasitic nematodes, and weeds validated that ASD is an effective approach to control various soilborne pathogens. This study aims to optimize the carbon ...

2013 National Turfgrass Evaluation Program Bermudagrass Test: 2015 Data, L. Parsons, J. Griffin, J. Hoyle

Kansas Agricultural Experiment Station Research Reports

Kansas represents the northernmost region in the central United States where bermudagrass can be successfully grown as a perennial turfgrass. Historically, few cultivars that have both acceptable quality and adequate cold-tolerance have been available to local growers. Because new introductions are continually being selected for improved hardiness and quality, both seeded and vegetative types need regular evaluation to determine their long-range suitability for use in Kansas.

Their research indicates high resolution remote sensing with small UAS can detect drought stress before it is visible to the human eye. Preliminary measurements of a golf course revealed interesting differences in fairways, tees, and greens between summer and fall seasons. Additional research will be conducted in 2016.


Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 1), R. Braun, D. Bremer, J. Fry 2016 Kansas State University

Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 1), R. Braun, D. Bremer, J. Fry

Kansas Agricultural Experiment Station Research Reports

In this study, annual nitrous oxide (N2O) emissions were greatest in urea and least in untreated (no N) among treatments. Differences were negligible due to irrigation treatment. Irrigation levels may be decreased further in the final year to induce slight stress on the low irrigation treatment. All fertilizer treatments maintained acceptable quality, however the controlled-release fertilizer resulted in more consistent visual quality ratings compared to urea and untreated. Urea fertilizer had higher peak fluxes after fertilization and overall annual emissions than polymer-coated N-fertilizer. Thus, controlled released N fertilizers, such as polymer-coated urea, in turfgrass systems could potentially help ...

Evolutionary Ecology Of Weeds, 1st & 2nd Editions, Jack Dekker 2016 Retired: Iowa State University-University of Guelph-Michigan State University

Evolutionary Ecology Of Weeds, 1st & 2nd Editions, Jack Dekker

Jack Dekker

2nd Edition, July 2016.  Evolutionary Ecology of Weeds is the story of WHAT, WHY and HOW some plant species invade and occupy habitats ripe for exploitation.  The nature of weeds is the evolution of adaptive traits for seizing and exploiting locally available opportunity.  Weeds are the consequence of human disturbance which creates opportunity spacetime, leaving unused resources eager for invasion by weeds.  The nature of weeds is the story of us, humans.  We created highly successful wild-crop-weed complexes that resist control.  We created them by channeling natural selection, the driver of biological change.  Plants invade by dispersing, colonizing, reproducing and ...


Impacts Of Biofumigation And Anaerobic Soil Disinfestation On Strawberry Production, Jennifer Renee’ Wheeler 2016 University of Tennessee - Knoxville

Impacts Of Biofumigation And Anaerobic Soil Disinfestation On Strawberry Production, Jennifer Renee’ Wheeler

Masters Theses

Due to the phase-out of methyl bromide, there is a need for alternative, nonchemical fumigation treatments in strawberry production. Anaerobic soil disinfestation and biofumigation are two non-chemical methods for controlling soilborne plant pathogens of strawberry. This study was designed to observe strawberry fruit nutrition and soil volatiles of a strawberry field being treated with biofumigation treatments, anaerobic soil disinfestation treatments, and a combination of the two alternative methods. A trial was conducted with 11 pre-plant soil-incorporated treatments arranged in a randomized complete block design with 6 rows (blocks). Biofumigation treatments consisted of deactivated mustard meal, deoiled mustard meal, mustard pellets ...

Information Thermodynamics Of Cytosine Dna Methylation, Robersy Sanchez Rodriguez, Sally Ann Mackenzie 2016 University of Nebraska-Lincoln

Information Thermodynamics Of Cytosine Dna Methylation, Robersy Sanchez Rodriguez, Sally Ann Mackenzie

Agronomy & Horticulture -- Faculty Publications

Cytosine DNA methylation (CDM) is a stable epigenetic modification to the genome and a widespread regulatory process in living organisms that involves multicomponent molecular machines. Genome-wide cytosine methylation patterning participates in the epigenetic reprogramming of a cell, suggesting that the biological information contained within methylation positions may be amenable to decoding. Adaptation to a new cellular or organismal environment also implies the potential for genome-wide redistribution of CDM changes that will ensure the stability of DNA molecules. This raises the question of whether or not we would be able to sort out the regulatory methylation signals from the CDM background ...


Ws-2 Introgression In A Proportion Of Arabidopsis Thaliana Col-0 Stock Seed Produces Specific Phenotypes And Highlights The Importance Of Routine Genetic Verification, Mon-Ray Shao, Vikas Shedge, Hardik Kundariya, Fredric R. Lehle, Sally Ann MacKenzie 2016 University of Nebraska - Lincoln

Ws-2 Introgression In A Proportion Of Arabidopsis Thaliana Col-0 Stock Seed Produces Specific Phenotypes And Highlights The Importance Of Routine Genetic Verification, Mon-Ray Shao, Vikas Shedge, Hardik Kundariya, Fredric R. Lehle, Sally Ann Mackenzie

Agronomy & Horticulture -- Faculty Publications

Arabidopsis thaliana is an important model organism with a robust network of resources that has been of enormous value to the plant science research community. The use of isogenic material as a reference point or control is critical for many types of experiments in plant molecular biology and genetics. Recently, we noticed that some seed from a common source of the widely used Columbia-0 (Col-0) strain gave rise to plants showing features atypical for this strain. Whole-genome DNA-sequencing and allelespecific PCR assays confirmed that the abnormal individuals contain multiple introgressions from the ecotype Wassilewskija-2 (Ws-2), as described below. This emphasizes ...
