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

Use Of The Antibiotics, Streptomycin And Terramycin, As Growth Stimulants For Orchid Seedlings., Margaret W. O'Neill
Biology ETDs
Antibiotics first came to the public's attention in 1945, when penicillin and streptomycin were released by the United States government to fight human diseases. Later, other antibiotics were released and experimental work was done on control of plant and animal diseases. By 1948 plant pathologists found that certain plant diseases such as walnut blight, tomato and pepper bacterial spot, soft rot, cucumber, downy mildew, chrysanthemum bacterial wilt, and lilac bacterial blight could be controlled by antibiotics.
A Distributional And Taxonomic Study Of Ratibida Columnifera Var. Columnifera, Ratiba Columnifera Var. Pucherrima, And Their Hybrids In New Mexico, Walter W. Marshall
A Distributional And Taxonomic Study Of Ratibida Columnifera Var. Columnifera, Ratiba Columnifera Var. Pucherrima, And Their Hybrids In New Mexico, Walter W. Marshall
Biology ETDs
The classification and distribution of Ratibida columnifera var. columnifera Woot. and Standl. and R. columnifera var. pulcherrima (DC.) Woot. and Standl. are complex. Some floras list R. columnifera var. pulcherrima as a purple colored form or variety of the species while other authors refer to this taxon as a separate species of Ratibida. The purpose of this study is to clarify the taxonomic status of the two forms by determining and differences in morphology, distribution, taxonomy, and ecology.
An attempt has been made to determine the route by which R. columnifera columnifera and R. columnifera pulcherrima were distributed. After this …
