Changes in gene expression under water stress in the flag leaf and seed head during the grain-filling stage of two spring wheat cultivars
Alotaibi, Fahad Saad (2018-05)Drought poses severe limitations on crop production. Therefore, drought tolerance mechanisms need to be better understood to select, modify and recommend certain cultivars of wheat. The grain filling stage of wheat development ... -
Comparative analysis of microRNAs in Flaveria species of C3, C3-C4 intermediate and C4 photosynthesis
Pokoo, Robert (2017-05)MicroRNAs (miRNAs) are a group of small non-coding RNAs that negatively regulate expression of their target genes at the posttranscriptional level. The miRNA-mediated gene regulation has emerged as one of the critical modes ... -
Effects of Elevated Carbon Dioxide on Ornamentals and Leafy Greens Grown in a Greenhouse
Poudel, Megha R. (2018-05-01)Carbon dioxide, being a major input for photosynthesis, plays an important role in plant production and propagation. To understand how elevated CO2 affects horticultural crops under greenhouse production, three studies ... -
Evaluating the response of teff [Eragrostis tef (Zucc.) Trotter] and hard red winter wheat (Triticum aestivum L.) to yield limiting factors in Oklahoma
Ali, Muaid Shaker (2013-07)Scope and Method: Weather conditions such as temperature and precipitation are the most important crop growth limiting factors in Oklahoma. Less precipitation is available for crop growth during the summer months due to ... -
Growth and Development of Setaria viridis (Poaceae) Under Normal and Shaded Light Regimes
Li, Qing (2019-05-01)Plants rely on photosynthesis to gain energy for growth, yet most plants are found with other plants, and therefore need to deal with varying degrees of shading. Shading by plants affects both the spectrum (especially red ... -
Influence of cover crops and their management on post-incorporation N2O emissions and nitrogen transfer to recipient crop
Singh, Hardeep (2020-12)Including cover crops in production systems for improving soil health and nutrient cycling has gained interest in recent years. Although cover crops may provide many agronomic and environmental benefits, they may also ... -
Influence of switchgrass management on soil microbial biomass and fatty acid methyl ester content in soil
Pebeck, Kaylee (2020-07)Switchgrass is a fairly new source of commercial biofuel feedstock. Its production can potentially preserve soil health and microbial functions in ecosystems. There is an increasing demand for large scale biomass production, ... -
Nitrogen management for climate change mitigation in the southern Great Plains
Wilson, Tracy M. (2014-12)Nitrous oxide (N2O) is a potent greenhouse gas (GHG), with a global warming potential 310 times that of carbon dioxide (CO2). Agricultural soil management in the U.S. is responsible for 69% of N2O emissions. Fertilizer ... -
Screening switchgrass (Panicum virgatum L.) for water stress tolerance
Fahej, Mohamed Ali (2012-05)Scope and Method of Study: Switchgrass can benefit from enhanced water stress tolerance as it will be grown in marginal areas. Whole plant and in vitro culture techniques can help to improve switchgrass biomass production ... -
Three essays: Reservoir management; switchgrass land leasing; and its environmental impact
Debnath, Deepayan (2012-12)First essay determines the optimal lake levels for Lake Tenkiller that maximizes the total net economic benefits derived from both marketed and non-marketed uses under stochastic inflows. It was found that for Lake Tenkiller ... -
Two-way interactions between bioenergy cropping systems and water resources
Yimam, Yohannes Tadesse (2014-12)Understanding the two-way interactions between bioenergy cropping systems and water resources is imperative for the successful deployment of these crops in the US Southern Great Plains (SGP); however, such information is ... -
Winter Biomass Yield, Year-Round Elemental Concentrations of 'Kanlow' Switchgrass, and Associated Soil Nutrients in a Zero Input Environment
Makaju, Shiva (Oklahoma State University, 2010-05-01)Switchgrass (Panicum virgatum L.) is a warm-season perennial species native to North America. It was selected by the U.S. Department of Energy (DOE) as the model herbaceous species for the development as a cellulosic ...
