Seed Certification In The Southeast, Sunanda Sakharam Rao

Masters Theses

[From the Introduction] [Abbreviated]

This paper is intended to be a review of the seed certification program operating in the United States. Here the certification is the responsibility of the individual states. The schemes are operated either by government agencies or by legally authorized seed growers associations.

The purpose of seed certification is to make available to the public high quality seed and propagating materials of superior crop plant varieties, so grown and so distributed as to insure genetic identity, varietal purity and mechanical quality. Fundamentally it is a system to improve yield and quality of field crops.

Role Of Extension Service In Rural Development, Sunanda Sakharam Rao

Masters Theses

[From the Introduction] [Abbreviated]

Of all the agencies and organizations cooperating with people in rural development work, the Agricultural Extension Service and its workers have a special and pivotal role. This is because both rural developoent and Cooperative Extension Service are educational programs involving large numbers of people, and they have the same fundamental objectives. The purpose for which this study was outlined was to discover how these programs differ by comparatively studying their educational nature.

Lateral Development Following Special Pruning Practices On Peach Shoots, Tayis S. Hamid

Masters Theses

[From the Introduction]

Because of its fruiting habit the peach creates a problem for growers. The problem is how to develop fruit wood nearer the trunk each year, so that propping, picking, spraying and fruit thinning will require about the same, rather than more labor each year.

The ever rising costs of production without the corresponding increases in retums have forced fruit growers to adopt time and labor saving devices in the production of their crop.

As a result of the above problem, this experiment was conducted to study and investigate the influence of some special pruning practices …

Forest Litter And Humus Types Of East Tennessee, John Thurlow Mcginnis

Masters Theses

Forest litter and humus types in East Tennessee, including the Great Smoky Mountains, have been the object of this study. The east Tennessee area is bordered on the east by the State Line Ridge in the Smoky Mountains and on the west by the Cumberland Mountains. The east Tennessee area is in the Ridge and Valley and Blue Ridge provinces as defined by Fenneman (1938). The Great Smoky Mountains, in the Blue Ridge province, are part of the Unaka Chain (King and Stupka 1950) and have relief of over a mile. The Ridge and Valley province is an intermountain belt, …

The Vegetation And Floristics Of Five Gorges Of The Cumberland Plateau, Harry L. Sherman

Masters Theses

The unglaciated Appalachian Plateaus, as part of the more extensive Appalachian highlands, represent some of the oldest land area in North America with respect to continuous land masses suitable for occupancy by terrestrial plants. These plateaus, along with the Blue Ridge Province and the Ozark and Ouachita highlands, had long been above marine waters when the Coastal Plain emerged, probably during the Miocene Epoch (Fenneman 1938). With the formation and southward advance of the great ice sheets of the Pleistocene, the existing plant life of the glaciated region was destroyed, thereby drastically reducing the botanical age of the otherwise ancient …

The Summer Season Climatic And Vegetational Gradient Between Point Barrow And Meade River, Alaska, Edward Ernst Cooper Clebsch

Masters Theses

The purpose of the present investigation was to examine the summer season climatic gradient between Point Barrow and Meade River, Alaska, and to determine to what degree the gradient is reflected in the vegetation of the area. The area under consideration includes the northernmost portion of the Arctic Coastal Plain of Alaska and extends from 70° 25' to 71° 25' north latitude and from 156° 30' to 157° 30' west longitude. All points in the area lie within thirty miles of the Arctic Ocean, and Point Barrow itself extends some four miles out into the ocean as a narrow gravel …

An Ecological Survey Of The Vascular Aquatic Vegetation Of The Cumberland Plateau In Tennessee, Franklin Delano Robinson

Masters Theses

A study of the vascular aquatic plants in the Cumberland Plateau in Tennessee was mad e during the summer of 1955. The purpose of this study was to find out the distribution of species in this area and try to learn some of the conditions under which the species involved survive. The species list for the area was arranged in alphabetical order under group headings according to the most frequently observed habit or position of growth. Under each species name the range and mean values determined for the carbon dioxide content, total acidity, total alkalinity, and pH of the surrounding …

A Study Of Plant Distribution Patterns At A Mid-Altitude Location In The Great Smoky Mountains National Park, Everette H. Cooley

Masters Theses

Introduction: Travelers in the Great Smoky Mountains are often impressed by the striking contrasts between the evergreen and deciduous vegetation types exposed to view along the mountain slopes. In the springtime one can look across the valley formed by the West Prong of the Little Pigeon River, toward the north-facing slopes of Sugarland Mountain, and see the intricate mosaic pattern of the vegetation as the new leaves of the deciduous trees unfold, spreading out in a wide fan in the lower coves and extending, tongue fashion, up the mountain slopes into the high coves between lead ridges. These deciduous forest …

Vegetation Of The Grassy Balds Of The Great Smoky Mountains National Park, Vernon Collis Gilbert

Masters Theses

On the tops of many mountains in the Southern Appalachians are areas which are essentially treeless and which are called "balds." These balds are of two general types, "heath balds" and "grassy balds." The heath balds are largely made up of woody ericaceous species, while the grassy balds are dominated by herbaceous species. This study is concerned with the grassy balds.

The problem of the origin of these grassy balds has long been of interest, and a great deal has been written about the general topic. In this thesis a review is made of the views and theories that have …

A Survey Of The Order Contortae In Tennessee, Melville B. Laite

Masters Theses

(Statement of the Problem) The problem has been to check all available Tennessee material in order to determine the taxonomic limits and distribution of the taxa belonging to the order of Contortae (Gentianales of Bentham and Hooker and others) as represented in the flora of Tennessee. In addition, keys have been arranged for the identification of the families, genera, and species.

Ethnobotany Of The Cherokee Indians, William H. Banks Jr.

Masters Theses

In September, 1951, a study of the Ethnobotany of the Cherokee Indians was suggested to the writer as the subject for his Master of Science thesis at the University of Tennessee, by Dr. Aaron J. Sharp. The idea met with immediate enthusiasm for a number of reasons.

The reserch [sic] involved in such a study would necessarily deal with people as well as plants, thus combining the writer's greatest interests. The project would also afford an excellent opportunity to work in close contact with a bontanically [sic] rich area, thus enabling the writer to strengthen his knowledge of nature.

A Taxonomic Survey Of The Myxomycetes Of The Great Smoky Mountains National Park, Arthur L. Welden

Masters Theses

Myxomycetes, with their curious combination of plant-like and animal-like characteristics, have intrigued biologists for over two centuries. Micheli in 1729 described several forms so accurately that his genera, and in some cases species, still can be recognized. Linnaeus, though contributing nothing himself, was able to include descriptions of seven species in his Species Plantarum. Micheli and Fries, among early biologists, recognized and commented on the plasmodial stage. They believed, as had their predecessors, that the Myxomycetes belong in the Gasteromycetes. Schrader in 1797 was one of the first to dissent from this view. However, final proof of the differences between …

The Effect Of Ultraviolet Radiation On The Pattern Of Spore Germination In Funaria Hygrometrica Hedw., Mary Elizabeth Case

Masters Theses

Introduction: In 1782 Hedwig published a morphological description of spore germination in mosses in his Fundamentum historiae naturalis muscorum frondosorum. Since then others (Schoene, 1906; Brown, 1919; Van der Wijk, 1932; Chalaud, 1932) have described spore germination in Funaria hygrometrica Hedw., the Cord Moss, reporting four general types of germination. This study was undertaken to determine the effect of ultraviolet radiation on the spore germination pattern of F. hygrometrica. No previous work is known on the effect of ultraviolet radiation on germination of moss spores.

Studies In The Families, Magnoliaceae, Illiciaceae And Schisandraceae Of Szech'uan, China, Ching-Yung Cheng

Masters Theses

Object of this study: Since the family Magnoliaceae was first described by J. H. Jaume St. Hilaire, its limit has been discussed and treated in various ways by different authors. The tendency of the treatments, however, is always to separate the remotely related groups and break this heterogeneous family into more homogeneous and well defined ones. According to Bentham & Hooker, Magnoliaceae includes three subfamilies, namely Magnolieae, Wintereae and Schisandreae. This treatment was followed by most authors until 1926, when Hutchenson broke these into three separate families: Magnoliaceae, Winteraceae and Schisandraceae. Recently, A. C. Smith separated Illicium from Winteraceae, and …

Check List Of The Trees And Shrubs Of Eastern Tennessee, Willa Love Galyon

Masters Theses

Introduction: The flora of East Tennessee is exceedingly rich both in numbers of species and individuals. Along the eastern border of the state we have the largest untouched remnants of the original hardwood forests of Eastern North America. The indigenous broad-leaved tree species outnumber those of any other equivalent area in this country, yet surprisingly little mention has been made of them in literature.
