Vegetation management along roadside and railroad right-of-ways
(University of Missouri--Columbia, 2018)Efficient transportation of freight as well as motorists requires effective control of vegetation on right-of-ways (ROW's). Traditionally on railroad ROW?s, residual herbicides are applied early in the growing season with ... -
Grasshopper and bee communities on missouri prairies : comparing reconstructions and remnants
(University of Missouri--Columbia, 2018)Tallgrass prairies once occupied a large swath of central North America, but now face the combined challenges of habitat loss and fragmentation. In Missouri, where less than 1% the historical prairie remains, prairies are ... -
Adaptation of soybean to tropical environments for smallholder farmers
(University of Missouri--Columbia, 2018)There are many traits that influence crop adaption to a new environment so that it can perform as a farmer would prefer. In these chapters, I have shown the influence of the genetic mechanisms behind pod shatter, days to ... -
Evaluation of the incidence, severity and forage nutritive value of common weed species in Missouri pastures
(University of Missouri--Columbia, 2017)Across the 2015-2016 growing seasons, 43 mixed tall fescue and legume pastures were surveyed to determine the effects of selected soil and forage parameters on the density of individual weed species and overall weed density. ... -
Investigations of 2,4-d-resistant waterhemp and seed treatment and herbicide interactions in soybean
(University of Missouri--Columbia, 2017)Field research experiments were conducted in 2015 and 2016 in Missouri to determine whether interactions are present between herbicides sprayed prior to planting and seed treatments in soybean. Two varieties of soybean ... -
Delayed maize lateral root determinacy induced by mild water deficit
(2017)The capability of roots to mine the soil for available water is essential for survival and productivity, especially under water-limited conditions. The formation and elongation of lateral roots is an important process ... -
The effects of drought stress and western corn rootworm feeding on maize root biology
(University of Missouri--Columbia, 2010)Drought and western corn rootworm (WCR), Diabrotica virgifera virgifera, can have substantial impacts on the potential yield of maize, Zea may L. Maize lines were selected to survey the level of diversity available for ... -
Soil wetting agents influences on soil hydrophobicity : the effects and mechanisms
(University of Missouri--Columbia, 2017)Soil water repellency (SWR), which causes uneven water distribution in top soil, is a common problem for sandy soils, especially on sand-based growing media such as USGA (United States Golf Association) greens. The SWR is ... -
The bacterial type III-secreted protein AvrRps4 is a bipartite effector
(University of Missouri--Columbia, 2017)Like humans, plants have an immune system to protect themselves against invading pathogens. Unlike humans, however, the plant immune system is inborn and genetically predetermined by resistance genes. Pathogenic bacteria ... -
Genetic and molecular analysis of soybean cyst nematode virulence
(University of Missouri--Columbia, 2017)The soybean cyst nematode (SCN) Heterodera glycines is the most economically important pathogen of soybean, capable of causing large scale yield loss on a global scale. Current management practices utilize host resistance, ... -
Comparative analysis of the role of cytokinin in feeding site formation induced by cyst and root-knot nematodes
(University of Missouri--Columbia, 2017)Cyst and root-knot nematodes are obligate plant parasites of global economic importance with a remarkable ability to reprogram root cells into unique feeding sites. Previous studies have suggested a role for cytokinin in ... -
High density mapping and quantitative trait loci analysis for fungal diseases in vitis aestivalis-derived 'Norton' and breeding for low palmitic acid in glycine max
(University of Missouri--Columbia, 2017)Vitis aestivalis-derived ‘Norton’, the official grape of the State of Missouri, is grown in many U.S. regions where V. vinifera production requires extensive pesticide use for fungal disease management. To identify genetic ... -
Effects of fire and thinning on Kansas oak woodlands
(University of Missouri--Columbia, 2017)Prior to Euro-American settlement, a mosaic of prairie, savanna, woodland, and forest existed within the Forest-Prairie Transition Region of the United States, with anthropogenic fire acting as an important driver in the ... -
Identifying bioactive phytochemicals in spent coffee grounds for cosmetic application through global metabolite analysis
(University of Missouri--Columbia, 2017)Annually, more than 6 million tons of spent coffee grounds (SCG) are generated worldwide. The present study explores the possible use of spent coffee grounds as the raw materials for cosmetics industry. The main objective ... -
Use of non-lethal endpoints to establish water quality requirements and optima of the Topeka Shiner (notropis topeka)
(University of Missouri--Columbia, 2017)Water quality influences growth, development, and physiology of aquatic vertebrates. Current criteria on water quality assessments are primarily based on lethal level experiments (e.g. LC50 tests), which are poorly suited ... -
Flower production and effect of flower harvest on berry yields within six American elderberry genotypes
(University of Missouri--Columbia, 2017)Cultivation of American elderberry (Sambucus canadensis) is increasing in North America for its use in dietary supplements. While the flowers of European elderberry (S. nigra) are commonly consumed as an anti-viral in ... -
Canopy recruitment dynamics in naturally regenerated longleaf pine (pinus palustris) woodlands
(University of Missouri--Columbia, 2017)The ecological and cultural values of the longleaf pine (Pinus palustris) ecosystem, in combination with an approximately 97 percent loss in historic range, has led to increasing interest in ecosystem restoration and ... -
Mechanical and thermal weed control in organic crops
(University of Missouri--Columbia, 2017)Effective weed control is one of the most yield-limiting factors in organic corn and soybean production. Additionally, the amount of tillage needed to control weeds in organic practice is often criticized for its negative ... -
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 ... -
Comparison of dual-polarization radar-derived and disdrometer drop-size distributions with S- and X- band radars
(University of Missouri--Columbia, 2017)There have been many studies on the evaluations of drop-size distributions and the parameters that affect these distributions, however, few, if any, have directly compared the relationship between the radar-derived parameters ...
