Flower production and effect of flower harvest on berry yields within six American elderberry genotypes
(University of Missouri--Columbia, 2017)
Cultivation of American elderberry (Sambucus canadensis) is increasing in North America for its use in dietary supplements. While the flowers of European elderberry (S. nigra) are commonly consumed as an anti-viral in Europe, the horticultural...
Heterochrony of floral and mating system characters between Nicotiana longiflora and N. plumbaginifolia
(University of Missouri--Columbia, 2007)
The evolution of selfing is one the most fascinating and common trends observed in flowering plants. Selfing flowers are often smaller than their outcrossing relatives, with reduced reproductive effort. The selfing species Nicotiana plumbaginifolia...
Adaptation of soybean to tropical environments for smallholder farmers
(University of Missouri--Columbia, 2018)
There are many traits that influence crop adaption to a new environment so that it can perform as a farmer would prefer. In these chapters, I have shown the influence of the genetic mechanisms behind pod shatter, days to flower, days to maturity...
Nectar in nicotiana : pollinator associations, sources of variation, and evolutionary consequences
(University of Missouri--Columbia, 2007)
Nectar is the primary floral reward offered by plants to attract pollinators. Pollinators often exhibit a preference for certain types of nectars over others. If pollinator preferences for certain nectar traits are strong ...
Ego trip
(University of Missouri--Columbia, 2017)
cultural assumptions with masculinity and flowers. The work was important to make because I was trying to question my sexuality through questioning the way that I am perceived through a cultural lens. It wasn't celebratory; it was perhaps a stepping...
Does history repeat itself? : Impact of climate on floral resources for bumble bees then and now
(University of Missouri--Columbia, 2014)
Reflectance sensors to predict mid-season nitrogen need of cotton
(University of Missouri--Columbia, 2008)
potential for accurate prediction of optimal N rate. Prediction accuracy was low at the first square stage but acceptable at mid square or early flower. These results suggest that variable-rate N applications to cotton based on real-time reflectance sensor...
Horticultural crop response to synthetic auxins
(University of Missouri--Columbia, 2019)
and 2018 at three locations in Missouri, research in production vineyards focused on the single-season effects of dicamba on hybrid grapes (Vidal blanc). During flowering and early fruit set, established grapes were exposed to low rates of dicamba...
Transfer of chromosomes through haploid induction in maize (Zea mays
(University of Missouri--Columbia, 2017)
and ScramBL sometime during pollen formation. This dissertation also describes the development of two new, rapid-cycling, miniature lines of maize: Fast-Flowering Mini-Maize A and B, produced to accelerate maize research (McCaw et al., 2016c). These lines...
Integrated management of the invasive weed, cut-leaved teasel (Dipsacus laciniatus L.) along a Missouri highways
(University of Missouri--Columbia, 2008)
four mile section of Highway interstate 70 in central Missouri. Seed characteristic such as viability after flowering, emergence pattern and persistence were conducted. Hyperspectral images were collected using airplane along I-70 to assess teasel...
Butterfly gardening: using volunteers to provide data on flower use
(University of Missouri--Columbia, 2006)
for 15 minutes from May through September 2002 and 2003. Volunteers observed most of the butterfly species expected in mid-Missouri. In addition to identifying and counting butterflies, they recorded the flowers on which any butterflies landed. Based on a...
Quantification and characterization of the antitumoral agent taccalonolides isolated from black bat flower (tacca chantrieri) in Indonesia
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Bat flower (Tacca chantrieri) is a widespread species that can be found in tropical regions of South East Asia. Phytochemical study reveals a class of anti-tumor compound called...
Occurrence and implicatons of biological network evolution following polyploidy
(University of Missouri--Columbia, 2014)
lead to the diversity and survival of some lineages of life, and by understanding network evolution, we may discover patterns that explain how organisms evolve. Specifically, we focus on the consequences of polyploidy on flowering time. Our work aids...
The depiction of smell in fifteenth-century Netherlandish painting as cultural sense memory and odor-cued prayer context
(University of Missouri--Columbia, 2016)
In the region now known as Belgium, fifteenth-century painters began to exploit the new medium of oil paint to achieve greater realism. This was to remove the barrier between painting and viewer. Odors such as flowers, incense, and perfumed oil...
Analysis of quaternary faults and associated deformation of sedimentary basin fill : inner continental borderland of southern California
(University of Missouri--Columbia, 2012)
-Carlsbad(SMC), and Coronado Bank Detachment(CBD)-Descanso faults. We interpret a [about]18 km wide step over from the NI-SMC positive flower structure in the north to the CBD-Descanso negative flower structure in the south adjacent to San Diego. These faults and stratigraphic...
Evolution and development of the paired spikelet trait in maize and other grasses (Poaceae)
(University of Missouri--Columbia, 2017)
, components and functions of these pathways are often conserved between plant lineages. While flowering in Arabidopsis occurs from the direct transition of the shoot apical meristem to a floral meristem, the grasses develop numerous axillary meristems...
Mating systems in Nicotiana longiflora and N. Plumbaginifolia : the effect of interspecific interactions
(University of Missouri--Columbia, 2008)
The research presented here was focused on the effects of interactions between Nicotiana longiflora and N. plumbaginifolia on their mating systems. First, I conducted a series of observations and pollination experiments ...
The impacts of partner abundance on benefits from facultative pollination mutualism
(University of Missouri--Columbia, 2010)
Partner abundance affects costs and benefits in obligate mutualisms, but its role in facultative partnerships is less clear. I investigated this topic in a small alpine pollination web in the Colorado Rocky Mountains ...
Evaluations of driftable fractions of dicamba and 2,4-D to selected herbaceous and woody plant species
(University of Missouri--Columbia, 2019)
Commercialization of 2,4-D and dicamba-resistant cotton and soybean has given producers another mechanism of action to control herbicide resistant weeds. As a result of the adoption of this technology, off-target movement ...
Biology and management of cut-leaved Teasel (Dipsacus laciniatus L.) in central Missouri
(University of Missouri--Columbia, 2006)
Cut-leaved teasel is a biennial invasive weed that grows along roadsides and low disturbed areas. This research was to determine growth characteristics, herbicide efficacy, and seed production of teasel. Growth characteristics ...
