Viability, vigor, and field performance of a low phytic acid, high phytase activity soybean line, CAPPA
(University of Missouri--Columbia, 2009)
study measured the vegetative and reproductive dry mass gain for each entry from the R5-R8 stages. Laboratory vigor experiments involving standard germination, accelerated aging, cold test, electrical conductivity, and tetrazolium testing were conducted...
Environmental regulation of the larval diapause of the southwestern corn borer, Diatraea grandiosella Dyar (Lepidoptera : pyralidae)
(University of Missouri--Columbia, 1973)
most data have been obtained for species which evolved in temperate regions (Andrewartha, 1952; Lees, 1955; Danilevskii, 1961; Beck, 1968; Mansingh, 1971)- Such species are subjected to marked seasonal changes in photoperiod and temperature. Experiments...
Abscisic acid: interactions with ethylene and reactive oxygen species in the regulation of root growth under water deficit
(University of Missouri--Columbia, 2011)
Abscisic acid (ABA) is involved in several responses to plant water deficits, including an important role in root growth maintenance. Studies of the ABA-deficient maize mutant viviparous 14 (vp14) showed that ABA-deficiency ...
Development and improvement of artificial diets for larvae of Diabrotica species using multidimensional design space techniques
(University of Missouri--Columbia, 2018)
of the maize seed companies are used by industry and public researchers in toxicity bioassays to detect decreases in susceptibility of western corn rootworm populations to Bt proteins. No artificial diet has been developed specifically for northern corn...
Reducing ergovaline and ergot alkaloid concentrations through fertilizer, herbicide and clipping management
(University of Missouri--Columbia, 2010)
rather than chemical NPK reduced ergovaline by at least 124 [mu] kg-1 DM. Another experiment showed the herbicide clethodim reduced ergovaline up to 72%. A third experiment, conducted with Clemson University and the University of Georgia, showed...
The balance between plant immunity and development: interactions of SRFR1 and TCP transcription factors
(University of Missouri--Columbia, 2013)
the transcriptional network controlled by TCPs. Results from these experiments will help identify how SRFR1 regulates the balance between plant development and immune responses....
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 ...
Partial characterization of Bt resistance and the bacteriome of western corn rootworm
(University of Missouri--Columbia, 2018)
Western corn rootworm (Diabrotica virgifera virgifera LeConte) and northern corn rootworm (Diabrotica barberi (Smith and Lawrence)) are major pests of maize in the USA. These pests have been managed with a variety of tactics ...
Management alternatives for urea use in corn and wheat production
(University of Missouri--Columbia, 2006)
for the 2005 experiment resulted in a significant and large yield response when treatments were applied in March compared to in January. Application of polymer- and gel-coated urea did not improve wheat yield relative to urea in either year. Agrotain + DCD...
Genetic engineering of soybean using candidate genes to improve drought tolerance
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Drought is one of the major abiotic stresses which affect productivity in soybean. Plants respond and adapt to drought stress through various biochemical ...
Molecular cloning and characterization of regulatory enzymes in threonine biosynthetic pathway from soybean
(University of Missouri--Columbia, 2007)
Soybeans (Glycine max [L.] Merr.) are a good source of protein and oil. Despite being a very good source of protein, soybeans nutritional value is limited by low proportion of sulfur amino acids methionine and cysteine ...
Behavioral responses of drosophila suzukii (diptera: drosophilidae) to olfactory and visual cues
(University of Missouri--Columbia, 2019)
conducted in laboratory cages to observe responses of D. suzukii to several doses of compounds individually and in combination. The addition of [beta]-cyclocitral to ethyl hexanoate resulted in a synergistic response from D. suzukii. Additionally, a simple...
Phosphorus nutrition in tall fescue : from stockpiling to seed production
(University of Missouri--Columbia, 2007)
Tall fescue (Festuca arundinacea) is the most important forage for beef production in the Midwest. Stockpiling tall fescue allows producers to extend the grazing season and reduce winter-feeding costs. In Missouri, forages ...
The underlying genetic control of maize root system architecture
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Maize (Zea mays ssp. mays) is one of the most widely cultivated and highest yielding grain crops in the world. The genetic and phenotypic diversity ...
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 arundinaceus (Schreb.) Dumort...
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 ...
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, ...
Corn tissue nutrient response related to soil health and fertility
(University of Missouri--Columbia, 2021)
Nutrient uptake in corn (Zea mays L.) is influenced by many different factors which include properties of soil health. The push for increasing soil health has raised the question of how soil health and fertility measurements ...
