Influence Of Seed Irradiation With X-Rays And Thermal Neutrons Upon Cell Size And Mitotic Activity In Root Tips Of Maize, Francis A. Haskins, Merwyn Davidson, Russell Beers

Department of Agronomy and Horticulture: Faculty Publications

In recent years a number of reports (for example, Caldecott et al., 1952, 1954, 1955; Schmidt and Frolik, 1951; Schwartz, 1954; Schwartz and Bay, 1956; Spencer and Cabanillas, 1956; Yagyu and Morris, 1957) have appeared which deal with the effects of treating seeds with various high energy radiations. In all cases it is reported that seedlings grown from appropriately-irradiated seeds are reduced in stature. This reduction in stature must necessarily result from irradiation-induced decreases in number and/or size of the cells comprising the seedlings. Although some quantitative data relating to irradiation-induced changes in cell size and mitotic activity are available …

Native Grassland Of Southwestern Iowa, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Studies of the prairie by the writer and Fitzpatrick during 1922-33 were both extensive and intensive. They were extensive in that they included an area of 60,000 sq. mi. in western Iowa, eastern Nebraska and portions of the four adjoining states. They were intensive in that a record of the kinds and distribution of grasses, the abundance and relative importance of forbs, and other pertinent data were ascertained and recorded separately for each of 135 selected areas. Since most of these prairies were examined two or more times each growing season, and many repeatedly during a five-year period, a clear, …

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, …

Food Habits Of The Uinta Ground Squirrel (Citellus Armatus Kennicott) On Some Meadows Of Mt. Timpanogos, Utah, Robert K. Shaw

Theses and Dissertations

Food habits of the Uinta ground squirrel were investigated on some open meadows on the south-east slope of Mt. Timpanogos. Special emphasis was placed on species of plants eaten; and preference of plants in relation to season, succulence, and phenology. Other investigations were made in reference to: parts of plants eaten, non-plant material eaten, daily and seasonal activities in relation to foraging, feeding procedures, and the relationship between plant cover and Uinta ground squirrel activity.

Genetic Variation In Bluebunch Wheatgrass, Max P. Dunford

Theses and Dissertations

Agropyron spicatum (Pursh) Scribn, and Smith, an important forage grass distributed primarily throughout western United States and northward into Canada, exhibits considerable ecological, cytological, and genetic variation. Twenty-five populations of 100 plants each were scored to obtain data on morphological and ecological variation. Statistical analysis of the data from fourteen of the populations showed that correlations between awn divergence and length, rhizomes with number of culms, adn diameter with number of culms were inconsistent or not significant. However, the correltion between rhizomes and diameter was significant in all populations.

The Comparative Mineral Requirements Of Pioneer And Climax Range Grasses, Paul L. Steele

Theses and Dissertations

A study was made to determine the effects of variable levels of nitrogen, phosphorus, and potassium upon several species of pioneer and climax range grasses, and to determine if these grasses differ in their ability to grow when supplied with low levels of these nutrients. Five grasses were used. The climax grasses were Agropyron spicatum and Agropryon smithii, and the pioneer grasses were Aristida longiseta, Sporobous cryptandrus, and Oryzopsis hymenoides.

Classification Of Root Systems Of Forbs Of Grassland And A Consideration Of Their Significance, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Plants other than grasses constitute an important part of the native grasslands of North America. Most of these are forbs, a few are shrubs and half-shrubs. Probably 85 to 90 percent of the forbs are perennial and most are as deeply rooted and many far more deeply rooted than the grasses. Their number varies considerably from place to place. In the prairie of the central part of the North American Lowland and on the hard lands and sandy soils of the Great Plains they compose, perhaps, between 5 and 15 percent of the vegetation. They are least abundant in the …

Revised Grain Standards...Their Effect On Nebraska Wheat In 1957, J. A. Goodding, C. J. Miller

Nebraska Agricultural Experiment Station: Historical Circulars

Although Federal grain standards for Hard Red Winter Wheat were revised in 1957, a Nebraska Experiment Station study shows that the new regulations had very little effect on grades received by wheat marketed at country points by Nebraska farmers in 1957. Results of the study are described in this circular.

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 …

A Study Of Physoderma On Three Species Of Portulacaceae, David L. Mumford

Theses and Dissertations

Three species of the Portulacaceae each infected by a Physoderma parasite were collected at several locations in Utah. The hosts have been identified as Claytonia lanceolata Pursh., Oreobroma pygmaeum (A. Gray) Howell, and Erocallis triphylla (S. Wats.) Rydb. Since our present knowledge of Physoderma on members of the Portulacaceae is meager, it seemed desirable to learn as much as possible about the parasite, its hosts, and the relationship between parasite and host. Plants of all three hosts activated from perennating organs were grown for extended periods of time under uniform conditions. Cold treatments were most successful in activating host perennating …

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 …

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.
