Manganese nutrition and photosynthesis in NAD-malic enzyme C-4 plants
(University of Missouri--Columbia, 2008)
NAD-ME activity and the continued supply of CO2 to bundle sheath cells. The objective of this research was to determine the Mn requirement for optimum photosynthesis and plant biomass production for two agriculturally important NAD-ME C-4 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 ...
Novel approaches in macroinvertebrate biomonitoring
(University of Missouri--Columbia, 2008)
The increasing popularity of benthic macroinvertebrate use for biological monitoring and assessment of lotic systems calls for new applications for regions with a lesser known fauna and an overall better understanding of ...
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 ...
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 ...
Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
(University of Missouri--Columbia, 2008)
Poison hemlock is a biennial, toxic and invasive weed that grows along roadsides, pastures and low-disturbed areas. Research was conducted to determine seed ecology, growth characteristics and response to herbicides. Seed ...
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 ...
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. ...
The role of genetic and phenotypic diversity in maize and its effects on aflatoxin accumulation by the fungus Aspergillus flavus
(University of Missouri--Columbia, 2008)
Accumulation of the potent carcinogen, aflatoxin, in maize poses a significant health risk to humans and animals. Most commercially grown maize lines are susceptible to infection by the fungus that synthesizes aflatoxin, ...
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 ...
Associations between Wolbachia, maize and Diabrotica virgifera virgifera
(University of Missouri--Columbia, 2008)
Diabrotica virgifera virgifera which is infected with Wolbachia, is the most significant and widespread pest to maize in North America and Europe. Wolbachia are obligate intracellular bacteria which seem to be limited to ...
Extracellular ATP, apyrase and nodulation of non-legumes
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] ATP is a universal energy source for biochemical reactions in all living organisms. Extracellular ATP (eATP) is well studied in animal processes such ...
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 ...
The semiaquatic heteroptera (Gerromorpha) of Thailand : faunistics, biogeography and phylogeography
(University of Missouri--Columbia, 2008)
Semiaquatic heteropterans (Gerromorpha) were collected from mountain streams and waterfalls and lowland ponds adjacent to the mountains were collected from 2002 to 2006. One hundred fifty-eight species representing 31 ...
Physiological traits underlying differences in salt tolerance among glycine species
(University of Missouri--Columbia, 2008)
Salinity drastically reduces crop yield by limiting water uptake and causing ion-specific stress. Soybean is sensitive to soil salinity. Previous studies, however, have shown that there is variability among soybean genotypes ...
