Bacterial Inoculants, Endophytic Bacteria And Their Influence On Nicotiana Physiology, Development And Microbiome, Andrea Marisa Sanchez Barrios
Bacterial Inoculants, Endophytic Bacteria And Their Influence On Nicotiana Physiology, Development And Microbiome, Andrea Marisa Sanchez Barrios
Theses and Dissertations--Plant and Soil Sciences
Soil and root microbial communities have been studied for decades, and the incorporation of high-throughput techniques and analysis has allowed the identification of endophytic/non-culturable organisms. This has helped characterize and establish the core microbiome of many model plant species which include underground and aboveground organs. Unfortunately, the information obtained from some of these model plants is not always transferable to other agronomic species. In this project, we decided to study the microbiome of the Nicotiana genus because of its importance in plant physiological and plant-microbe interactions studies. The data obtained was used as baseline information that allowed us to better …
Physiological Parameters, Isoenzymes And Hormonal Profiling In Different Varieties Of Date Palm In United Arab Emirates, Saeed Rashed Hamad Al Shamsi
Physiological Parameters, Isoenzymes And Hormonal Profiling In Different Varieties Of Date Palm In United Arab Emirates, Saeed Rashed Hamad Al Shamsi
Aridland Agriculture Theses
The present investigation was carried out to explore the physiological changes in early, mid and late varieties of date palms in United Arab Emirates. The concentrations of biochemicals and antioxidant compounds, activities of antioxidant enzymes with their isoenzyme profiles, endogenous phytohormone contents were studied from preflowering, flowering, and post-flowering stages. Two varieties each from early (Shaham, Khanezi), mid (Barhee, Nabthasaif) and late (Khasab, Fardh) flowering types were used in the study. The protein content was higher in early varieties in preflowering stage, but lower in other two varieties. The phenol showed an opposite trend to protein. Ascorbic acid, reduced glutathione …
Poultry Production Messaging: A Content Analysis Of Three National Newspapers From 1994 To 2014, Stuart Estes
Poultry Production Messaging: A Content Analysis Of Three National Newspapers From 1994 To 2014, Stuart Estes
Graduate Theses and Dissertations
Consumers are increasingly concerned with the use of antibiotics and hormones in poultry production, and the news media is the primary way consumers gain knowledge about this subject. This study assessed articles about antibiotic and hormone use in poultry production from the New York Times, USA Today, and the Wall Street Journal from 1994 to 2014. This study employed a content analysis methodology to assess selected articles (n = 139) for key messaging about antibiotic and hormone use in poultry production, article tone, article framing, and article journalistic quality. Data gathered from key messages were assessed for emergent themes that …
Northwest Arkansas Consumer Perceptions Of Poultry Production, Stuart Estes
Northwest Arkansas Consumer Perceptions Of Poultry Production, Stuart Estes
Agricultural Education, Communications and Technology Undergraduate Honors Theses
Poultry production holds an important place in Arkansas economically and as a food source. The importance of poultry production ultimately hinges on the demands of the consumers and the perceptions that drive their purchases. With this in mind, this study surveyed consumers to assess their perceptions of poultry production in Arkansas. The instrument used to survey consumers was created by the researcher and an expert committee at the University of Arkansas. Consumers were interviewed through direct communication at grocery stores in northwest Arkansas. Data gathered from the study were analyzed for descriptive and correlational statistics. Data showed that consumers were …

Degradation Of Estrogens In Dairy Waste Solids: Effects Of Acidification And Temperature, D. Raj Raman, Alice C. Layton, Lara B. Moody, James P. Easter, Gary S. Sayler, Robert T. Burns
D. Raj Raman
Manure–borne estrogens are increasingly recognized as a potential ecological hazard. However, sample–handling protocols for these compounds are not clearly delineated in the literature, nor are comparisons between assays for estrogens. A study was conducted to explore the degradation of estrogen in separated dairy manure waste solids (press cake), using three popular assay types. Estrogens were measured by enzyme–linked immunosorbent assay (ELISA), gas–chromatography mass–spectroscopy (GC–MS) and a recombinant yeast estrogen reporter assay. As measured by GC–MS, background estrone concentrations were approximately 100 ppb, while 17β–estradiol concentrations were one–third of the estrone concentration, and 17β–estradiol concentrations were below the detection limit (10 …

G80-537 Reproductive Trace Anatomy And Physiology Of The Cow, Gene H. Deutscher
G80-537 Reproductive Trace Anatomy And Physiology Of The Cow, Gene H. Deutscher
University of Nebraska-Lincoln Extension: Historical Materials
Knowledge of basic reproduction will help a producer to obtain higher conception rates when using estrous synchronization and/or artificial insemination. The reproductive performance of a cow herd has a great influence on the income and profit realized. A good understanding of the anatomy and physiology of the cow's reproductive system is, therefore, beneficial for successful management. Knowledge of basic reproduction will help a producer to obtain higher conception rates when using estrous synchronization and/or artificial insemination. It will also allow for a better understanding of pregnancy examinations, reproductive diseases and calving difficulty problems.
