Competition and management of volunteer corn (Zea Mays L.) in corn
(University of Missouri--Columbia, 2011)
Volunteer corn (Zea mays L.) is the result of corn kernels remaining in the field following harvest and is a competitive weed in a number of subsequent crops. With widespread adoption of glyphosate-resistant (Gly-R) corn, ...
Molecular characterization of CLE peptide mimicry during cyst nematode pathogenesis
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Plant-parasitic cyst nematodes establish intimate parasitic relationships with their hosts by penetrating the root as motile juveniles and migrating ...
Influence of herbicide applications and common pasture weeds on total forage yield and nutritive values in tall fescue pastures and hayfields in Missouri
(University of Missouri--Columbia, 2009)
The addition of several new herbicides labeled for pastures or hayfields has led many growers to question their options for weed management in these environments. In addition, little is known about the influence of common ...
Cotton and maize primary root growth responses to water deficit : comparative physiological and metabolic analysis
(University of Missouri--Columbia, 2019)
Cotton (Gossypium hirsutum L.) and maize (Zea mays L.) are important economic crops that can suffer significant yield loss under drought. Cotton and maize root systems have fundamentally different architectures, in addition ...
Modification of fatty acid composition in soybean seeds to improve soybean oil quality and functionality
(University of Missouri--Columbia, 2011)
The purpose of this project is to modify the fatty acid composition in soybean seeds to improve soybean oil quality and functionality. By sequencing the FAD2-1A and FAD2-1B genes in 24 plant introductions, we identified ...
Nested association mapping and accuracy of predicting genomic breeding value for agronomic and seed composition traits in three interspecific soybean populations
(University of Missouri--Columbia, 2019)
increment between 300 and 390 individuals (1%). Marker density had little impact on the prediction accuracy across traits, with a significant increment in prediction accuracy up to 1423 markers (18.5%). The training population design Across all families had...
Assessing Missouri soybean fields for azoxystrobin resistant cercospora sojina
(University of Missouri--Columbia, 2021)
in controlling C. sojina in the field. Unfortunately, azoxystrobin fungicide-resistant isolates of C. sojina have been recovered in many soybean growing areas of the U.S. Fungicide-resistant isolates of C. sojina were first detected in 2011 and 2012 in two...
Field pennycress management in upstate Missouri
(University of Missouri--Columbia, 2017)
Field pennycress has the potential to serve as a cover and oilseed crop. A seed oil content of 25 to 36 percent has created interest in pennycress domestication. This research evaluated management strategies for growing ...
Research to advance our understanding of off-target dicamba movement in United States agriculture
(University of Missouri--Columbia, 2021)
The commercialization of dicamba-resistant (DR) crops and subsequent increase in post-emergent applications of dicamba has contributed to millions of acres of dicamba injury to sensitive plant species since 2016. The ...
Resource extraction, resistance, and religion in Nicaragua
(University of Missouri--Columbia, 2019)
My dissertation examines the causes of protest over resource extraction in Nicaragua, and underlines the role of religion as a catalyst for sustained and successful challenges against resource extraction. With few exceptions, ...
The influence of fusarium species on sweet potato plant performance, root yield and quality
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Sweet potato (Ipomoea batatas (L.) Lam.) is a global important food crop, that has recorded an increase in the consumption, and demand for especially ...
Characterization of soybean rooting depth in response to different environmental conditions
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Soybean (Glycine max (L.) is currently grown throughout the world because it has been adapted to many environments and because of the high ...
Switchgrass responses to manganese availability
(University of Missouri--Columbia, 2019)
Manganese (Mn) is an essential micronutrient and has a broad range of functions for all plant growth and reproduction. It plays a crucial role in NAD-ME C4 photosynthesis, including as a constituent of the water splitting ...
Identification and management of glyphosate-resistant annual bluegrass (Poa annua L.)
(University of Missouri--Columbia, 2010)
Annual bluegrass is the most problematic weed on golf courses in the Transition Zone and Southern United States. Applications of glyphosate are common on dormant zoysiagrass to remove winter annual weeds. In 2007, a suspect ...
Horticultural crop response to synthetic auxins
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Rising adoption of dicamba-tolerant soybeans increases the potential exposure of grapes to dicamba, where off-target injury may occur via particle or ...
