The Morphological, Physiological, And Genetic Underpinnings Of Intraspecific Salinity Tolerance In Sorghum Bicolor, Ashley N. Henderson
Graduate Theses, Dissertations, and Problem Reports
Decreases in land quality and quantity threaten the efficient production of agriculturally and economically pivotal crops. Such reductions in arable lands are a consequence of population growth and urbanization, and often result in the introduction of various abiotic stresses. The most common abiotic stressors include water limitation (drought), water logging (over watering), poor water quality (salinity), and extreme temperatures (cold, frost, heat). Each of these stressors negatively impact plant growth, development, and yield. Soil salinity, specifically, is a considerable constraint affecting lands used in agriculture. Salts in the soil rise both naturally and through anthropogenic factors making the abundance a …

Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas
Kansas Agricultural Experiment Station Research Reports
Bermudagrass is a productive forage species when intensively managed. However, it has periods of dormancy and requires proper management to maintain forage quality. Legumes in a bermudagrass sward could improve forage quality and reduce fertilizer usage; however, legumes are difficult to establish and maintain with the competitive grass. Clovers can maintain survival once established in bermudagrass sod, and may be productive enough to substitute for some N fertilization. This study was designed to compare dry cow performance on a bermudagrass pasture system that included ladino and crimson clovers (Legume) vs. bermudagrass alone (Nitrogen). Use of legumes in wheat-bermudagrass pastures did …

Water Use And Productivity Of Corn And Grain Sorghum In Long-Term Crop Sequences, R. M. Aiken
Kansas Agricultural Experiment Station Research Reports
Dryland corn and grain sorghum showed similar water productivity of grain and above-ground biomass, relative to respective growing periods, at the apparent yield frontier. The yield frontier indicates the maximum productivity for a given amount of water use. This similarity in productive response to water supply provides a foundation for improved precipitation use. Yield gaps relative to the yield frontier appear substantial. Water supply during the grain filling period was the primary driver of feed grain crop productivity, and was affected more by available soil water at pollen shed than by precipitation during grain-fill or available water at maturity. Grain …

Utilizing Rhizospheric And Bacterial Endophytes For Use As Potential Bio-Fertilizers For Sustainable Agricultural Production, Vincent Peta
Electronic Theses and Dissertations
Brassica carinata crop production offers an exciting alternative approach to the energy crisis when looking at novel ways to power our motor vehicles. Bacterial endophytes, while residing in host-plant tissues, offer a wide array of plant growth promotion benefits such as nitrogen fixation to impart nitrogen (N) nutrition, phosphate (P) solubilization to make soil-bound phosphate more mobile in soil for plant uptake, can suppress pathogenic microbes such as fungus and produce plant growth hormones to offset stress incurred by the plant. Previous literature has shown that there is large interest in studying endophytes from economically important crops such as wheat, …

Quantitative Imaging Of Cell-Level Auxin Cytokinin Outputs In Soybean And Model Plants, Paul Gaillard
Electronic Theses and Dissertations
Auxin and cytokinin are major plant hormones that orchestrate plant development. These hormones are involved in cell division and differentiation and their spatio‐temporal balance controls organ initiation and maturation. Even though independent transcriptional responses to these hormones have been characterized, their concomitant outputs have not been described. We developed methodology to determine auxin-cytokinin relative output (ACRO) ratios at cellular resolution. Hormone-specific fluorescent markers that localize to the nucleus were used to report transcriptional outputs of auxin and cytokinin. Multiphoton microscopy and image data processing were used to quantify their relative ratio at cellular level in three-dimensional tissue volumes. This strategy …

Reverse Genetic Analysis Of Ehd1 For An Association Between Flowering Time And Seed Dormancy In Rice (Oryza Sativa L.), Yeter Karakoc
Electronic Theses and Dissertations
This research aimed to understand the evolutionary mechanism of seed dormancy and flowering time and to provide basic knowledge for the manipulation of germination features in crop breeding. Flowering time and seed dormancy are two adaptive traits for flowering plants. Seed dormancy (SD) helps regulate the timing of germination to promote the survival of seed-bearing plants in adverse environments. Cereal crops and weedy/wild relatives, such as Asian cultivated rice and weedy rice (Oryza sativa L.), have weak and strong seed dormancy, respectively. Thus, weedy and cultivated rice has been used as a model system to investigate mechanisms of seed dormancy …
