Agronomic and pest interactions in no-till corn and soybean wih fall versus spring herbicide applications
(University of Missouri--Columbia, 2006)Fall herbicide applications have increased in popularity in recent years. Little is known of how fall herbicide applications impact soil conditions, insect populations, and winter and summer annual weed populations. Few ... -
Biodiversity of ants (Hymenoptera: Formicidae) in restored grasslands of different ages
(University of Missouri--Columbia, 2006)Grasslands are an endangered ecosystem. Unfortunately, few studies monitoring the health of these grasslands have included arthropods, thus leaving out a vital biodiversity component. Ants have been proven to be reliable ... -
The effect of environment on seed composition of tofu and natto soybean cultivars
(University of Missouri--Columbia, 2006)Composition of soybean seeds is important to manufacturers of tofu and natto food products. The effect of environment on seed composition of tofu and natto soybean cultivars was measured in Missouri in 2004 and 2005. The ... -
Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed ... -
Function of abscisic acid in maintenance of maize primary root growth under water deficit
(University of Missouri--Columbia, 2006)Previous studies suggested that ABA accumulation is required to maintain maize primary root elongation under water deficit and that one of the functions of ABA is to restrict ethylene evolution. These studies were conducted ... -
Impact of alternate host phenology amd alternate hose-transgenic corn interactions on the Western corn rootworm (Coleoptera: Chrysomelidae)
(University of Missouri--Columbia, 2006)With the increasing adoption of transgenic maize with resistance to rootworms, combined with glyphosate tolerance, as a control tactic for western corn rootworm, Diabrotica virgifera virgifera LeConte, an understanding of ... -
Reaction of soybean cultivars to waterlogged soil
(University of Missouri--Columbia, 2006)Irrigating soybean prior to an extensive rain can result in waterlogged soil that may cause root damage and plant death. Some soybean cultivars tolerate waterlogged soils. The objective of this study was to evaluate tolerance ... -
A study of transcript profiling of soybean roots during nitrogen fixing symbiosis
(University of Missouri--Columbia, 2006)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nodulation is a symbiotic association between a host plant and its bacterium. The result of this interaction is the formation of a novel organ, the ... -
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 ...
