Price Discovery And Futures Spreads For U.S. And Chinese Rice Futures Market, Wei Yang

Graduate Theses and Dissertations

Rice, the primary staple food for more than half the world's population, is the second world's most consumed food grain. In recent years, world rice price has increased and become more volatile especially in the period 2007-2010. Rice price volatility has a huge impact on Asian countries, especially countries in Southeast Asia where rice is a staple food for millions of households. Private market tools to manage price risk and discover price such as futures markets have been analyzed and assessed as possible solutions to coping with rice price volatility issue. Two primary functions of agricultural commodities futures markets are …


European Consumers' Attitudes Towards Cisgenic Rice, Anne-Cécile Delwaide Dec 2014

European Consumers' Attitudes Towards Cisgenic Rice, Anne-Cécile Delwaide

Graduate Theses and Dissertations

The enhancement of existing plant breeding techniques, such as cisgenesis, allows plant breeders to enhance an existing cultivar quicker and with little to no genetic drag. Cisgenesis is the genetic modification of a recipient plant with natural gene(s) from a sexually compatible plant. Unlike transgenesis, which is the genetic modification of a recipient plant with gene(s) from any non‐plant organism, or from a donor plant that is sexually incompatible with the recipient plant, the results of cisgenesis could occur naturally over time. Currently, both cisgenic and transgenic products are classified as genetically modified organisms (GMOs) and are labeled as such …

Determination Of Starch Lysophospholipids In Rice Using Liquid Chromatography Mass-Spectrometry (Lc-Ms), Lei Liu, Chuan Tong, Jinsong Bao, Daniel Le Waters, Terry J. Rose, Graham J. King Jul 2014

Determination Of Starch Lysophospholipids In Rice Using Liquid Chromatography Mass-Spectrometry (Lc-Ms), Lei Liu, Chuan Tong, Jinsong Bao, Daniel Le Waters, Terry J. Rose, Graham J. King

Adjunct Associate Professor Daniel LE Waters

Acquisition of a complete understanding of rice starch lysophospholipids (LPLs), their biosynthetic pathways, genetic diversity, and the influence of genotype by environment interactions has been hampered by the lack of efficient high throughput extraction and analysis methods. We hypothesized a single-step aqueous n-propanol extraction combined with liquid chromatography mass spectrometry (LCMS) could be employed to analyze starch LPLs in white rice. Our investigation found different grinding methods showed little effect on the final LPL detected and a simple single-step extraction with 75% n-propanol (8mL/0.15g) heated at 100 oC for two hours was as effective as an onerous multi-step extraction method. …

Biological Sciences Faculty Research and Publications

Seed dormancy is an important agronomic trait in cereals. Using deep dormant (N22), medium dormant (ZH11), and non-dormant (G46B) rice cultivars, we correlated seed dormancy phenotypes with abscisic acid (ABA) and gibberellin (GA) metabolism gene expression profiles and phytohormone levels during seed development and imbibition. A time course analysis of ABA and GA content during seed development showed that N22 had a high ABA level at early and middle seed developmental stages, while at late developmental stage it declined to the level of ZH11; however, its ABA/GA ratio maintained at a high level …

Biology And Control Of Rice False Smut Caused By Ustilaginoidea Virens (Teleomorph Villosiclava Virens), Andrew Clayton Jecmen

Graduate Theses and Dissertations

Rice false smut (FS), a disease caused by Ustilaginoidea virens (Cke.) Takahashi (1896), was first reported in northeastern Arkansas counties in 1997. The first objective of this research was to establish a collection of U. virens isolates from geographically diverse regions of Arkansas. Three U. virens isolates and chlamydospores from `Templeton' and `Clearfield-151' rice cultivars were used to determine the effects of temperature and pH on mycelial growth and germination. A nested-PCR protocol and histological methods were used to determine if U. virens infects and colonizes rice seedlings and spikelets on panicles. The sensitivity of three U. virens isolates was …


Efficacy Of Rice Insecticide Seed Treatments At Selected Nitrogen Rates For Control Of The Rice Water Weevil, Lissorhoptrus Oryzophilus Kuschel, Mallory Elise Everett May 2014

Efficacy Of Rice Insecticide Seed Treatments At Selected Nitrogen Rates For Control Of The Rice Water Weevil, Lissorhoptrus Oryzophilus Kuschel, Mallory Elise Everett

Graduate Theses and Dissertations

Seed-applied insecticides are the standard control method used to prevent rice water weevil (Lissorhoptrus oryzophilus Kuschel) injury to rice (Oryza sativa L.) roots, and often results in greater yields than rice that receives no seed-applied insecticide. Yield increases from seed-applied insecticides often occur even when insect pressure is low and should not cause yield loss. The research objective was to evaluate the effect of urea-nitrogen rate and seed-applied insecticide on number of rice water weevil larvae, nitrogen uptake and rice grain yield. Six trials were conducted at the Pine Tree Research Station (PTRS) and the Rice Research Extension Center (RREC) …


Milling And Functional Properties Of Co-Mingled Rice Cultivars, Nikhil N. Basutkar May 2014

Milling And Functional Properties Of Co-Mingled Rice Cultivars, Nikhil N. Basutkar

Graduate Theses and Dissertations

Differences have been observed in the milling and functional properties of different rice cultivars, particularly between hybrid and pureline cultivars. Co-mingling of rice cultivars commonly occurs during harvest, storage and drying operations. Thus, there is a need to study the effect of co-mingling on the milling and functional properties of rice cultivars. Two long-grain, hybrid (H) cultivars CL XL745 and CL XL729 and two long-grain, pureline (P) cultivars CL 151 and Wells were used to prepare CL XL745/CL 151 (H/P), CL XL745/CL XL729 (H/H) and Wells/CL 151 (P/P) co-mingles, mixed in various proportions. Milled rice yield (MRY), head rice yield …


Methane Emissions And Ammonia Volatilization From Drill-Seeded, Delayed-Flood Rice On A Silt-Loam Soil In Arkansas, Christopher Wade Rogers May 2014

Methane Emissions And Ammonia Volatilization From Drill-Seeded, Delayed-Flood Rice On A Silt-Loam Soil In Arkansas, Christopher Wade Rogers

Graduate Theses and Dissertations

The Environmental Protection Agency (EPA) currently uses a single methane (CH4) emissions factor of 160 kg CH4-C ha-1 for a primary rice (Oryza sativa L.) crop. The emissions factor is based on studies that do not adequately represent current management practices in Arkansas. Another concern is pre-flood fertilizer nitrogen (N) management, as the common N source, urea, is prone to loss via ammonia (NH3) volatilization. Thus, the objective of this research was to investigate trace gas emissions from rice on a silt-loam soil, including CH4 emissions as influenced by nitrogen (N) fertilization (i.e., optimal N and no N) in 2011, …


Mn-Euvering Manganese: The Role Of Transporter Gene Family Members In Manganese Uptake And Mobilization In Plants, Amanda L. Socha, Mary Lou Guerinot Apr 2014

Mn-Euvering Manganese: The Role Of Transporter Gene Family Members In Manganese Uptake And Mobilization In Plants, Amanda L. Socha, Mary Lou Guerinot

Dartmouth Scholarship

Manganese (Mn), an essential trace element, is important for plant health. In plants, Mn serves as a cofactor in essential processes such as photosynthesis, lipid biosynthesis and oxidative stress. Mn deficient plants exhibit decreased growth and yield and are more susceptible to pathogens and damage at freezing temperatures. Mn deficiency is most prominent on alkaline soils with approximately one third of the world’s soils being too alkaline for optimal crop production. Despite the importance of Mn in plant development, relatively little is known about how it traffics between plant tissues and into and out of organelles. Several gene transporter families …

Effects Of Cerium Oxide Nanoparticles In Cereals: Insights Into The Toxicity Mechanisms And Macromolecular Modifications, Cyren Mendoza Rico

Open Access Theses & Dissertations

Despite the inundation of studies on the interaction of engineered nanomaterials (ENMs) with plants, investigations involving complete life cycle (i.e from seedling establishment to full maturity) are still lacking. Assessments on the nutritional value of plants cultivated to full maturity in ENMs-treated soil are also missing. Cerium oxide nanoparticles (nCeO2) have significant interactions with plants; however, there are no life cycle studies yet on their implications in cereals like rice (Oryza sativa L.), wheat (Triticum aestivum L.), and barley (Hordeum vulgare L.). These cereals are globally important crops that support the economic activity, and nutritional and health needs of billions …


Interactions Of Herbicide Mixtures In Imidazolinone-Resistant Rice, John Caleb Fish Jan 2014

Interactions Of Herbicide Mixtures In Imidazolinone-Resistant Rice, John Caleb Fish

LSU Master's Theses

Propanil has long been a staple of weed management in rice production. The introduction of IR rice allowed for the use of imidazolinone herbicides in crop for the control of red rice. Six studies were conducted in 2011 and 2012 to evaluate the weed control interactions, synergistic, antagonistic, or additive, of imazethapyr or imazamox when mixed in a single application with propanil, thiobencarb, or a pre-packaged mixture of propanil plus thiobencarb. Blouin’s modified Colby’s was used to determine if a synergistic, antagonistic, or additive response occurred. Two studies were established to evaluate imazethapyr at 0 and 70 g ha-1, or …


Development Of A Loop-Mediated Isothermal Amplification For The Detection Of Burkholderia Glumae, Maria Alejandra Caldera Jan 2014

Development Of A Loop-Mediated Isothermal Amplification For The Detection Of Burkholderia Glumae, Maria Alejandra Caldera

LSU Master's Theses

Bacterial panicle blight is among the three most limiting diseases of rice production in the United States. Yield loss up to 40% has been reported from rice fields severely infested with bacterial panicle blight. The disease is caused by Burkholderia glumae and B. gladioli. Although, both species produce similar symptoms and are closely related, but B. glumae strains are more aggressive and cause more severe symptoms on rice. Bacterial panicle bight is difficult to manage in the absence of effective chemical control measures. Rapid and early disease detection is needed to avoid severe yield losses. Several techniques have been developed …
