(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Soybean cyst nematode (SCN) Heterodera glycines Ichinohe is the most serious pest of soybean [Glycine max (L.) Merr.] in the world. The effectiveness of breeding soybean SCN...
Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
(University of Missouri--Columbia, 2008)
no dormancy restriction. Poison hemlock plants were actively growing in mid-March, and growth increased exponentially through mid-May. Biomass produced between mid-March and mid-May, considering all plant densities studied, range from 13 to 3,464 kg/ha. Most...
Interplanting of a deficient soybean stand
(University of Missouri--Columbia, 2008)
The planting of adequate soybean seeds does not always materialize into a satisfactory final plant stand. Many different environmental factors play an important part in the process of soybean germination and emergence. ...
Molecular characterization of genetic resistance to soybean cyst nematode in soybean line SS97-6946
(University of Missouri--Columbia, 2008)
Soybean Cyst Nematode (SCN) (Heterodera glycine) is the most damaging pest of soybean and estimated annual yield losses are 1.5 billion dollars in USA. Breeding resistant cultivars is the most efficient means to control ...
Characterization of raffinose synthase genes in soybean
(University of Missouri--Columbia, 2009)
As the use of soy products in foods and feeds increases, it is ever more important to consider the nutritional value of each component of the seed. The carbohydrate component is largely composed of sucrose, raffinose, and ...
Comparative analysis of aquatic insect, amphipod, and isopod community composition along environmental gradients in rheocrene spring systems of Missouri
(University of Missouri--Columbia, 2010)
Spring systems in Missouri harbor a unique biota and provide critical initial discharge from subterranean aquifers to streams. However, little research has been conducted on the crenobiology or ecology in these systems. ...
Prairie stream ecology : temporal and spatial patterns of macroinvertebrates
(University of Missouri--Columbia, 2018)
patches to enable recolonization of streams after disturbance. Leptophlebia konza Burian was thought to be restricted to its type locality of Konza Prairie, Kansas; however, a population was discovered at Hi Lonesome Prairie in Missouri during an extensive...
Integrated management of the invasive weed, cut-leaved teasel (Dipsacus laciniatus L.) along a Missouri highways
(University of Missouri--Columbia, 2008)
Cut-leaved leaved teasel is an invasive, exotic, and noxious weed in Missouri. Biennial plant infest roadsides and undisturbed areas. Studies regarding seed biology, detection, and control measures were conducted to improve ...
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 intracellularly until...
The balance between plant immunity and development: interactions of SRFR1 and TCP transcription factors
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Plants have developed a highly effective immune system for resisting microbial pathogens. One layer of the plant innate immune system is effector-triggered immunity. This immune...
Reflectance sensors to predict mid-season nitrogen need of cotton
(University of Missouri--Columbia, 2008)
Nitrogen (N) is an essential nutrient for cotton production; consequently there is a tendency to over-apply nitrogen. High N causes excessive vegetative growth and delayed crop maturity, which result in increased cost in ...
The biology and ecology of tuber aestivum mycorrhizae establishment in the greenhouse and the field
(University of Missouri--Columbia, 2008)
Truffles, of the ectomycorrhizal genus tuber, are cultivated in plantations to offset declining wild production. Although methods for truffle plantation management have been published, methods for the production of ...
An attentional theory of issue-carrying capacity
(University of Missouri--Columbia, 2018)
of the extent to which differing cognitive styles affect the scope of problem identification and prioritization. Integrating insights from both political behavior and psychology research, this dissertation argues that women's lower cognitive threshold of urgency...
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 ...
Characterization of the insect cuticle sclerotization hormone bursicon and bursicon-regulated genes in the house fly Musca domestica
(University of Missouri--Columbia, 2008)
Bursicon is a neurohormone that regulates the cuticle sclerotization and wing expansion process in insects. Bursicon is a heterodimeric cystine knot protein containing two subunits, burs [alpha] and burs [beta], which are ...
Recommendations for tree establishment in tall fescue-based silvopasture
(University of Missouri--Columbia, 2008)
Silvopasture offers Midwest landowners the opportunity to plant trees in their pastures without significant loss of forage production. However, much of the pasture in the Midwest is dominated by tall fescue (Schedonorus ...
Efficacy of oriental mustard (Brassica juncea L. Czern.) seed meal for weed and disease control in turf
(University of Missouri--Columbia, 2009)
Pest management in turf involves the use of fumigants such as methyl bromide, as well as selective pesticides. However, the loss of methyl bromide and development of disease resistance to fungicides suggests that more ...
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 ...
