Evaluation Of Botanical Oil Formulations For Management Of Powdery Mildew And Mites, Adriane Lorraine Cannon Dec 2004

Evaluation Of Botanical Oil Formulations For Management Of Powdery Mildew And Mites, Adriane Lorraine Cannon

Masters Theses

Experiments were conducted to evaluate the effects of newly created soybean oil formulations on powdery mildew (Erysiphe pulphra ), photosynthesis, phytotoxicity, and broad mites (Polyphagotarsonemus latus (Banks)) on dogwood ( Cornus florida (L.) 'Cloud Nine') trees, and to evaluate the amounts of formulations that are deposited and washed off of peach (Prunus persica, (L.)) leaves, dormant oak (Quercus phellos, (L.) ), and viburnum ( Viburnum x juddii) twigs after simulated rainfall. Oil treatments were applied using a back pack mist blower sprayed pre- and post- inoculation of powdery mildew to evaluate powdery mildew, photosynthesis, and phytotoxicity. Oil treatments were also applied to the dogwood ...


Levels And Patterns Of Genetic Diversity In The Rare And Endangered Cumberland Stitchwort, Minuartia Cumberlandensis (Caryophyllaceae), Charles Thomas Winder Dec 2004

Levels And Patterns Of Genetic Diversity In The Rare And Endangered Cumberland Stitchwort, Minuartia Cumberlandensis (Caryophyllaceae), Charles Thomas Winder

Masters Theses

Sequences of a highly variable nuclear gene (G3pdh) were used to characterize genetic diversity within and among populations of the endangered rockhouse endemic, Minuartia cumberlandensis (Wofford and Kral) McNeill (Caryophyllaceae), and compared to a widespread and abundant related species, M. glabra (Michaux) McNeill. By reconstructing phylogenetic relationships among G3pdh variants (haplotypes) and observing the geographical distribution of those ordered variants, an attempt was made to gauge the effects of historical and contemporary population processes acting within the species, particularly those with potential implications for long-term conservation. Both M. cumberlandensis and M. glabra were found to have high overall genetic (haplotype ...

Field Evaluations Of Herbicides On Vegetable, Small Fruit, And Ornamental Crops, 2000, 2001, & 2002, Ron E. Talbert, Mike L. Lovelace, Eric F. Scherder, Mayank S. Malik Oct 2004

Field Evaluations Of Herbicides On Vegetable, Small Fruit, And Ornamental Crops, 2000, 2001, & 2002, Ron E. Talbert, Mike L. Lovelace, Eric F. Scherder, Mayank S. Malik

Research Series

Field evaluations of herbicides provide the chemical industry, governmental agencies, such as IR-4, and the Arkansas Agricultural Experiment Station with an evaluation of herbicide performance on small fruit, vegetable, and ornamental crops grown under Arkansas conditions. This report provides a means for disseminating information to interested private and public service weed scientists.


A Brief Note On The Authorship Of The First Flora Virginica: Clayton, Gronovius, And Linnaeus, Joan K. Stemmler Oct 2004

A Brief Note On The Authorship Of The First Flora Virginica: Clayton, Gronovius, And Linnaeus, Joan K. Stemmler

Virginia Journal of Science

A modern Flora of Virginia will soon be published, providing an occasion to remember the publication of the first Flora Virginica in the 18th century and to establish the proper attribution of its authorship. Based on a manuscript by John Clayton, Flora Virginica was published in two parts in 1739 and 1743 by the Dutchman Johan Frederick Gronovius. Although both names are printed on the title page, the book is often cited with Gronovius listed as the author. This tradition, interpreted in modern understandings of plagiarism, has led to an assertion that Gronovius misrepresented Clayton's work as his own ...

Systematics And Species Concepts In The Genera Lentinus Fr. And Panus Fr., With Emphasis On The Lentinus Tigrinus, L. Crinitus And Panus Lecomtei Complexes, Edward A. Grand Aug 2004

Systematics And Species Concepts In The Genera Lentinus Fr. And Panus Fr., With Emphasis On The Lentinus Tigrinus, L. Crinitus And Panus Lecomtei Complexes, Edward A. Grand

Doctoral Dissertations

The monographic work of Pegler (1983) on Lentinus has established the taxonomic guidelines for most recent studies involving members of the genus (Moncalvo et al. 2002, Rolen 2001, Krüger 2002). Pegler’s taxonomic hierarchy combined both Lentinus Fr. and Panus Fr. into one large genus, Lentinus Fr. The combination of these genera and its validity was one of the reasons for beginning this study. For generic level comparisons, ribosomal DNA sequence data can be helpful for determining relationships among taxa (Binder and Hibbett 2002, Hibbett and Vilgalys 1991, 1993, Hibbett and Donoghue 2001, Moncalvo et al. 2002, Thorn et al ...


Effects Of Management And Population Size On Genetic Diversity Of Eggert's Sunflower (Helianthus Eggertii; Asteraceae), John Howard Starnes Aug 2004

Effects Of Management And Population Size On Genetic Diversity Of Eggert's Sunflower (Helianthus Eggertii; Asteraceae), John Howard Starnes

Masters Theses & Specialist Projects

Helianthus eggertii (Asteraceae) is a federally threatened sunflower species that typically grows between open woods and barrens. This species has both sexual and asexual modes of reproduction, which can influence the amount of genetic diversity present within and among populations. Maintaining genetic diversity is one of the primary objectives in managing threatened species or populations. Fire and population size may influence genetic diversity. Two Inter-Simple Sequence Repeat Markers (873 and MAO) were used to characterize many important genetic parameters of 17 populations in 2003 and four populations in 2004. This information was used to assess the effectiveness of different conservation ...
