Evaluation of teosinte genetic diversity for agronomic and domestication traits in maize /
(University of Missouri--Columbia, 2017)
for adaptation and fitness related traits in the Teosinte Synthetic population. Maize plays a central role in the US agriculture and food production, as well as has the greatest molecular and phenotypic diversity than any crop species. My research study strongly...
Establishing, characterizing and deploying novel insect cell lines
(University of Missouri--Columbia, 2017)
Insect cell lines are convenient and powerful tools that were initially used in viral propagation, optimization of viral pesticides, cell-virus interactions, and recombinant protein productions. The most commonly used cell ...
Habitat manipulations to enhance the abundance and diversity of pollinators visting helianthus annuus l.
(University of Missouri--Columbia, 2016)
Insect pollinators face many challenges with the development of modern agriculture. These challenges, such as reduction in habitat range and landscape fragmentation, may be overcome by diversifying the plant community. By planting intercrops...
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 ...
Establishment and yield of bioenergy miscanthus on clayplan soil ladscapes
(University of Missouri--Columbia, 2015)
these properties when grown on degraded, and consequently, less productive soils in traditional agricultural settings. Two independent studies were conducted over the 2013-14 growing seasons to (1) quantify how both rhizome quality and depth of soil from...
Corn physiology and yield response to hybrid and seeding rate on claypan soils
(University of Missouri--Columbia, 2015)
Yield improvements over the past few decades have been attributed to increasing optimum plant population and not the increase of grain produced per plant. A goal in precision agriculture is to identify seeding rates that optimize yield...
Comparison of mosquito communities collected from differing livestock locations and an examination of phenotypic traits exhibited by four latitudinally separated populations of Aedes albopictus (Skuse)
(University of Missouri--Columbia, 2013)
-Missouri agricultural locations having differing primary livestock hosts and (2) genetic differences between populations of Aedes albopictus (Skuse) collected from four differing latitudes. Adult mosquito collections from 15 trapping locations that maintained 5...
Effect of far-red induced shade-avoidance responses on carbon allocation in arabidopsis thaliana
(University of Missouri--Columbia, 2016)
this change in growth causes young, growing leaves to export less of the sugar they make (keeping more for themselves), but fully mature leaves did not change how much sugar they exported. Agriculture is all about getting plants to turn sunlight into products...
Influence of herbicides application on weed and tall fescue management and grazing distribution in Missouri pastures
(University of Missouri--Columbia, 2012)
One weed that is of concern in Missouri pastures that can be detrimental is Northern dewberry (Rubus flagellaris Willd.). This weed can be detrimental due its production of spines which can injure grazing animals and also ...
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, ...
Soil characteristics and subsequent corn development following partial corn residue removal in a no-till, corn-soybean rotation
(University of Missouri--Columbia, 2013)
If producers employ corn (Zea mays L.) residue removal for ethanol production, soil and subsequent corn development characteristics could be affected. Little research has evaluated partial corn residue removal from baling ...
Effect of temperature on a soybean [Glycine max (L.) Merr.] mutant
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean is influenced by temperature and light, and global warming has been shown to reduce soybean yields. In this study we tested the germination of ...
Glyphosate resistance : pollen movement within a common ragweed (Ambrosia artemisiifolia L.) population and herbicide release from common waterhemp (Amaranthus rudis sauer) plants
(University of Missouri--Columbia, 2011)
Common ragweed and Common waterhemp are native, summer annual weeds distributed widely throughout the United States. Both weed species have developed resistance to the broad-spectrum herbicide glyphosate. Research was ...
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 ...
Influence of entomopathogenic fungi from forest and urban habitats on founding pairs of reticulitermes flavipes (rhinotermitidae)
(University of Missouri--Columbia, 2015)
In forest habitats, termites break down woody debris and assist in nutrient cycling of carbon and nitrogen. However, infestations in suburban habitats have given subterranean termites a high priority for pest management. ...
Predator diversity impacts herbivore abundance and behavior with cascading effects on the prevalence of a vector-borne plant pathogen
(University of Missouri--Columbia, 2013)
There is growing concern about the loss of biodiversity; particularly of organisms at higher trophic levels, such as predators, which face a disproportionately higher risk of extinction. As predator diversity declines there ...
Soybean emergence, growth, and development following corn stover removal
(University of Missouri--Columbia, 2012)
The Energy Independence and Security Act of 2007 mandates the use of 21 billion gallons of biofuel from cellulose or other advanced forms by the year 2022. Corn stover is an attractive choice for cellulosic ethanol production ...
Historical landscape interactions and patterns of invasion by subterranean termites (Isoptera: Reticulitermes) in subdivisions of different ages
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The subterranean termite genus Reticulitermes includes some of the most economically destructive termites in the United States, where it is estimated ...
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 ...
Allelopathic effects and removal of overseeded ryegrass on bermudagrass
(University of Missouri--Columbia, 2010)
Allelopathy is a complex phenomenon among plants that involves the production of defensive chemicals that influence the growth and survival of adjacent plants. Plants like perennial ryegrass become suspect when bermudagrass ...
