Identification and characterization of glyphosate-resistant common ragweed
(University of Missouri--Columbia, 2007)
A revolution in production agriculture has occurred over the past decade; the development and use of herbicide-resistant crops. Glyphosate is an effective, broad spectrum and offers flexible application timing with minimal ...
Viability, vigor, and field performance of a low phytic acid, high phytase activity soybean line, CAPPA
(University of Missouri--Columbia, 2009)
Plants store inorganic phosphate (Pi) in seeds as phytic acid (PA). Phytic acid chelates essential macro and micronutrients in developing seeds forming phytate, which is nutritionally unavailable to monogastric livestock. ...
The sublethal effects of ecdysone agonists on the attractiveness, responsiveness, fertility and fecundity of oriental fruit moth, a comparative examination with codling moth on larval feeding damage
(University of Missouri--Columbia, 2006)
were observed. Differences were also detected in the internal fruit damage between the two moth species....
Identification, characterization, and management of glyphosate-resistant waterhemp (Amaranthus rudis sauer.) in Missouri
(University of Missouri--Columbia, 2008)
The possibility of in waterhemp has been of concern to Midwest corn and soybean producers due to a heavy dependence on glyphosate as a weed control tool and the increased incidence and problematic nature of waterhemp in ...
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 ...
Genotype, environment and GE interaction effect on soybean oil composition
(University of Missouri--Columbia, 2005)
Changing the content of the five major soy-oil fatty acids is important to enhance food, fuel and other applications of soybean oil. In addition to genetic effects, the growth environment can significantly affect oil ...
The effect of environment on seed composition of tofu and natto soybean cultivars
(University of Missouri--Columbia, 2006)
by varying the planting date and by planting at 7 to 10 locations in four soybean-producing regions in Missouri. The carboydrates sucrose, raffinose, and stachyose were measured by high performance liquid chromatography (HPLC), and protein and oil were...
Management alternatives for urea use in corn and wheat production
(University of Missouri--Columbia, 2006)
Traditionally, urea has been incorporated to avoid losses of N by ammonia volatilization. However, this option is not available when topdressing wheat. The objective of this project is to evaluate several strategies designed ...
Predator-prey interactions involving the soybean aphid (Hemiptera: Aphididae) in Missouri
(University of Missouri--Columbia, 2007)
The recently introduced soybean aphid, Aphis glycines Matsumura, is found in all soybean growing areas within Missouri. Despite soybean aphid's widespread distribution, it has reached economic threshold in few soybean ...
Characterization of raffinose synthase genes in soybean
(University of Missouri--Columbia, 2009)
[about]10% of the meal. Both raffinose and stachyose are considered anti-nutritional units; sucrose is considered nutritionally useful. Monogastric animals, including humans, lack the alpha-galactosidase enzyme required for the metabolism of raffinose...
Dissipation and carryover of imidazolinone herbicides in imidazolinone-resistant rice (Oryza sativa)
(University of Missouri--Columbia, 2007)
The development of Imidazolinone (IMI) Resistant (IR) rice now allows rice producers to selectively control red rice (Oryza sativa, O. rufipogon, and O.nivara), weedy relatives of commercial rice (O. sativa). Imazethapyr ...
Armillaria species in the Missouri Ozarks forests
(University of Missouri--Columbia, 2005)
In the Missouri Ozark Mountains, species of the white-rot wood decay fungus Armillaria contribute to oak decline. To investigate the relationships of Armillaria species with their hosts, the DNA fingerprinting technique ...
Molecular characterization of soybean resistance to soybean cyst nematode
(University of Missouri--Columbia, 2009)
The soybean cyst nematode, Heterodera glycines, is a devastating pathogen to soybean worldwide. This obligate parasite establishes specialized feeding cells within host roots that are required for completion of the nematode ...
Sulfur metabolism in Glycine max [L.] Merr : characterization of serine acetyletransferase and O-acetylserine (thiol) lyase
(University of Missouri--Columbia, 2006)
Soybean (Glycine max [L.] Merr) is considered an excellent protein source for both humans and livestock. Further improvement of quantity and quality of soybean protein is vital for maintaining the utility of this versatile ...
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 ...
Fatty acid variation between forage species and within populations and fatty acid content of beef finished on pasture with different forage species
(University of Missouri--Columbia, 2008)
We describe two experiments; the first experiment was conducted in a greenhouse where four forage species - orchardgrass (Dactylis glomerata L.), tall fescue [Lollium arundinaceum (Schreb.) S.J. Darbysh = Schedonorus ...
Plasticity of soybean (Glycine max (l.) Merrill) root system development under mild water deficit
(University of Missouri--Columbia, 2008)
Drought is the major abiotic factor limiting soybean yield in the US. Under water deficit conditions, root systems may exhibit developmental plasticity resulting in morphological changes that extend the water-absorbing ...
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 ...
Soybean seed components as affected by nodal position, environmental conditions, and irrigation
(University of Missouri--Columbia, 2005)
Soybeans (Glycine max [L.] Merr.) are a major source of vegetable protein and edible oil. The nutritional quality of these seed components depends upon the relative abundance of specific proteins and fatty acids. Additionally, ...
