An Evaluation Of Conservation Reserve Lands In Relation To Pheasant Production And Survival, Richard M. Bartmann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ring-necked pheasant (Phasianus colchicus) is one of the most important upland game species over much of the nation. It is also one of the most difficult to effectively manage for the increasing hunter population. The high value of agricultural lands renders habitat improvement programs by state agencies a financial impossibility except on an extremely localized basis. Therefore, the primary pheasant management tool largely remains hunting season manipulation.

The federal government through various agricultural programs may have an influence upon pheasant habitat. Public Law 540 entitled "Agricultural Act of 1956," more commonly referred to as the "Soil Bank …

The Ideology Of The John Birch Society, Max P. Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is designed to examine and evaluate the basic beliefs and actions of the John Birch Society. It is not intended to determine the proper location for the Society on the American political spectrum, but to merely represent an opinion. An objective approach is intended, but the conclusion expresses a point of view, which, I hope, is clear and consistent enough to allow those who may disagree to take issue.

There is a great deal of room for disagreement on a subject such as this. The sources used in determining the content of this presentation are listed in the …

Ionic And Osmotic Effects On Growth, Transpiration, And Osmotic Pressure Of Salt Tolerant Plants, Don L. Chadwick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt tolerant plants have been the subject of considerable interest and study by scientists of arid regions. Ability of these plants to survive and grow in saline habitats has been attributed to such characteristics as: development of high osmotic pressures to counteract the soil moisture stresses, ability to utilize waters of high salinity, and possession of a protoplasm resistant to toxic ion accumulation.

The Initiation Of Infection By Dna From Bacteriophage Lambda, Gerald D. Elseth

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Deoxyribonucleic acid isolated from bacteriophage λ can infect Escherichia coli K12 in the presence of adsorbed helper phage (Kaiser and Hogness, 1960; Kaiser, 1962). The manner in which λ DNA enters the cell and the possible role of helper phage in the penetration process is still not clear. Kinetic studies conducted in this laboratory during the initial stages of infection by λ DNA demonstrate a requirement for helper function during the penetration of an infectious molecule. Further investigation into this problem is needed and was the major objective of this study.

The Utah Fleet: A History Of Ships In The United States Navy That Bore Utah Place Names And Personality Names, Robert Anthony Sumbot

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Down through the annals of history, man has perpetually engaged in conflicts; out of necessity he has progressed a long way from the bow and arrow stage of warfare. By the very nature of man's identity he has been a living example of progress and development. He never stands still during war or peace. Out of each encounter it appears he has learned and added a little more to the mechanics and theory of warfare, thereby making each war a succession of progress. This is a study of man's efforts to use and control the vast watery barriers which face …

The Effect Of Protective Materials On The Overwintering Of Hardy Annuals, Candytuft And Stocks, Melvin S. Burningham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many hardy annual flowers will live through the winter if there is sufficient snow protection. Since snow cover is not consistent from year to year it has been suggested that hardy annuals planted in late summer and provided with some kind of protection before severe freezing begins will live through the winter successfully. Not only would this enable plants to bloom four to six weeks earlier, but would also enable gardeners to utilize flowers not commonly grown in northern Utah.

Some studies conducted at the Utah Experiment Station in Farmington have indicated that plants such as candytuft and snapdragons can …

Saponin Content And Some Pod And Blossom Characteristics Of Alfalfa As Related To Seed Infestation By The Alfalfa Seed Chalcid, Ronald D. Morse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The alfalfa seed chalcid, Bruchophagus ruddi Guss., is a jet-black hymenopteran wasp. The destructive nature of this pest has been recognized since the latter part of the nineteenth century. Every year thousands of acres of alfalfa seed are destroyed, with infestation reaching as high as 8 5 percent in some areas. In Utah the chalcid annually ruins from 5 to 25 percent of the alfalfa seed. Much of this damage goes unnoticed, as infested seed is commonly blown out in the trash during harvesting and cleaning operations . The extent of damage is not restricted to the United States. Wherever …

The Inhibition Of Water Uptake In Sugar Beet Roots By Ammonia, Darrel Marshall Stuart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Various ammonium salts, urea, aqua ammonia, and anhydrous ammonia are important sources of nitrogen for the fertilization of agricultural crops. While ammonia and its compounds are useful as fertilizers, they can be, and often are, toxic to many plants (Willis and Rankin, 1930; Stout and Tolman, 1941; Raleigh, 1942; Stoll, 1954; Lorenz, 1955; Grogan and Zink, 1956; Allen, 1962; Cooke, 1962; Allred, 1963; Court et al, 1964; Hood and Ensminger, 1964). There are also products which have been designed to retard the oxidation of ammonia and its compounds (Go ring, 1962). It is therefore important that the effects of ammonia …

The Influence Of Organic Matter And Ph On Transformations Of Nitrites To Elemental Nitrogen, Mohammad A. Rashid

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen occupies an important and prominent place in plant and animal nutrition. Large quantities are required by plants and must be available in the soil. Recently the use of nitrogenous fertilizers has increased manyfold. In view of the importance of this element in crop production, even greater use is anticipated in the coming years. In order to make full use of the applied nitrogen, continued investigations of soil-nitrogen relationship are imperative; however, this element presents many complex and challenging problems to investigators.

Simultaneous Movement Of Water And Herbicides In Unsaturated Soils, Ming-Shyong Yang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since weed killers were developed in the early part of the decade beginning in 1940, herbicides have been increasing in use until they are now widely used to control weeds. The application of herbicides has thus become a regular agricultural and ecological practice.

Physio-Chemical Changes In Relation To The Rest Period Of Peach And Apricot Trees, Hussein Ibrahim El-Mansy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many plants require exposure to low temperature for a certain period during each year. This was determined more than a century ago. Understanding this phenomenon, known as the rest period, is part of a larger problem of understanding the factors which determine the ability of an organism to grow. The property of rest is ultimately a property of the actively growing cells, rather than that of the cells involved with protection and support.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The problems of phosphate fertilization have attracted the attention of agronomists, nutritionists, and other biological scientists due to the importance of phosphorus in animal and plant nutrition. However, the fundamental behavior of phosphorus in soil systems is not well understood. Because of its far-reaching effects, a solution of a portion of this problem is of importance.

A Study Of The Factors Influencing The Synthesis Of Tobacco Mosaic Viral Rna In A Partially Purified Synthesizing System, Agnes P. Fok

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research on biosynthesis of tobacco mosaic virus (TMV) ribonucleic acid (RNA) in vitro has been reported by Cochran, et al; Karasek and Schramm; Kim and Wildman; Cornuet and Astier; and Tongur and Baland in. It has been postulated that the replication of a number of viruses containing single-stranded RNA is accompanied by the formation of a virus-specific double-stranded helical RNA, the replicative form. This has been demonstrated both for animal and bacterial viruses including MS2. The double helical structure of purified replicative form of MS2 was established by X-ray diffraction studies. One of the strands was shown to be a …

An Ecological Study Of Ditylenchus Dipsaci (Kuhn) Filipjev. In A Field Of Alfalfa, Shu-Ten Tseng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ditylenchus dipsaci (Kuhn) Filipjev. is one of the most destructive nematodes to crop plants. It attacks and damages more than 300 species of cultivated and uncultivated plants. The nematode can be differentiated into many races, each of them having a preference for a group or even a single plant species.

Alfalfa stem nematode is one of the races in this species which attacks the above ground portion of alfalfa but does not infest the roots. Larvae of this nematode may migrate from the plant tissue to soil in moist conditions. These nematodes migrate actively to nearby plants or are carried …

Simultaneous Flow Of Heat And Water In Plant Tissue, Gaylon Sanford Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although biological phenomena may be partially described in a general way without the use of mathematics and physics, the experimental results may be more meaningful if they are analyzed on the basis of physical and mathematical laws. The complexity of biological systems has made the application to them of mathematics and physics rather difficult, and only recently has much progress been made. Although it has yet been possible to describe only a few simple biological systems by actual equations, a great deal of qualitative information may be obtained by applying physics and mathematics. Russell (1960, p. 439) said

In principle …

The Effect Of Soil Adsorbents On The Thermodynamic Properties Of Soil Water System, Taghi Manbeian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It has been generally recognized that the surface phenomena of the solid particles such as shrinking and swelling, water- holding capacity, water' movement, and cation exchange are important in understanding the physical properties of the soil. Clay is the most prevalent material in the colloidal fraction of many soils. Because of the complex nature of the surface of clays and the small size of the particles, the direct study of surface phenomena is difficult. Thermodynamic functions change in accordance with changes and organization within the system. Thus, an examination of the thermodynamics of surface phenomena provides some understanding of the …

The purpose of this study was to consider how the rooting of cuttings may be affected by such methods and factors as: type of cutting, time of year when cuttings are best taken, differences between individual species, use of chemicals for the treatment of cuttings, rooting media, and the care of cuttings in the propagation beds.

In the past 35 years scientists have done considerable experimenting with the application of organic chemicals on the roots, stems and leaves of various plants. These organic chemicals have come to be known as "plant hormones" or "plant regulators." They have proved to be …

Nitrification In Three Different Soils In Polyethylene Bags In The Field Overwinter, William R. Olmstead

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrification, the process whereby ammonical-nitrogen (NH₄⁺ - N) is changed into nitrate-nitrogen (NO₃^--N), is one of the more important biochemical processes associated with agriculture. Nitrate appears to be the form of N that most crops can most readily utilize.

The Effect Of Decomposing Organic Matter On Zinc Level In Soil And Plants, Kamilia Shoukry Mohamed Shoukry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

That proportion of the total zinc (Zn) in the soil that is available to plants is variable, and little is known about the various forms of Zn or even the extent to which it occurs. Because of the complexity of the problem, most workers have approached the problem of availability of Zn to plants from the opposite point of view, that is, the forms in which the added or available Zn becomes unavailable.

Susceptibility Of Selected Alfalfa Clones To Lygus Bugs In Relationship To Seed Production, Charles G. Summers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah ranks as one of the major producers of alfalfa seed in the nation. In 1964, 6.02 million pounds of cleaned seed were produced in the state. This resulted in an income of 1.7 million dollars to Utah seed producers for that year (Agricultural Statistics, 1965).

The Influence Of Clipping And Moisture Stress On Translocation In Crested Wheatgrass, James Miller Mayo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water movement in soils containing moisture below field capacity is extremely slow, thus requiring a continuous expansion of the plant root system to meet the transpiration demands placed on the plant (20, 21, 12, 19). It has been shown that internal moisture deficits result in reduced growth, and often death of the plant (22, 28, 25, 29, 34). Thus a healthy and continuously expanding root system may be necessary for good plant growth.

The Complex Formation Of Silver Ion With Ribonucleic Acid, Guanosine, Inosine And Related Compounds And Peroxidase-Like Activity Of A Haemundecapeptide Prepared From Horse Heart Cytochrome C, José Angel Reinosa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of nucleic acids in plant and animal cells as carriers of genetic information and as protein biosynthesis agents is well recognized. It is also known that nucleic acid is a component of all viruses.

Takahashi (45) and Fraenkel-Conrat (16) demonstrated that the protein component of tobacco mosaic virus is non-infectious to the host plant, although it is identical to the original virus morphologically. The virus ribonucleic acid (RNA) alone was infectious, however.

Deoxyribonucleic acid (DNA), which is present in chromosomes, displays a very specific function. The chromosome long has been accepted as the carrier of the hereditary unit, …

Nature Of Non-Biological Decomposition Of Nitrite In Acid Media, Mukkatira Kariappa Mahendrappa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Curiosity is the cause of investigations, and the thirst for knowledge originates from it. Many times at the end of investigations, the number of questions raised are greater than those for which answers are sought. Therefore, all the information gathered through scientific investigations may not be of value for immediate application in practical life. Nevertheless, no research can be considered less important than the other because the integration of several scientific findings considered less less important at the time of investigation may reveal something of very high significance. Similarly, the study of various transformation reactions that the added fertilizers undergo …

The Influence Of Soil Moisture Regimes And Atmospheric Environments On Transpiration And The Energy Status Of Water In Plants, Sampatrao A. Gavande

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant responses to different soil moisture regimes have been extensively studied. Because of interactions between the soil, plant and climatic factors, few convincing generalizations concerning the influence of soil water on the transpiration of water by plants have been established. Generally single factors or at most the interaction of two have been studied at any one time. Useful theories describing the conditions of water retention in plant tissues and movement of water through plants have been proposed. Equally useful theories have been suggested for describing the retention and transmission of water in soil. The integration of these theories and their …

Studies Of Peronspora Trifoliorum Debary Cause Of Downy Mildew Of Alfalfa, Sheldon B. Waite

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Downy mildew of alfalfa (caused by Peronospora trifoliorum d By) was found to be epidemic on susceptible varieties of alfalfa in northern Utah during 1965. The increase in the amount of downy mildew present was due to the more abundant rainfall and cooler than normal temperatures which prevailed during the summer months of 1965 (Environmental Science Services Administration, 1965). The author observed many of the highly susceptible varieties of alfalfa had 25-30 percent of their leaflets infected with the downy mildew fungus. Because of the epidemic developments of alfalfa downy mildew, an investigation was undertaken to explore the following questions …

A Survey Of Verticillium Albo-Atrum From Tomato Fields Of Northern Utah, Jean Redmond Musselman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Verticillium wilt has long been a major disease of tomatoes in Utah. The disease was recognized long before the causal agent was known. In 1932, Dr. H. L. Blood was given the task of investigating a wilt disease that was causing heavy losses to Utah's tomato industry (5). The disease was thought to be caused by Fusarium oxysporum f. lycopersici (Sacc.) Snyder & Hansen. Through his investigations Dr. Blood found Verticillium albo-atrum Reinke and Berthold to be the cause of the disease. He began the laborious task of finding a resistant variety of tomato and transferring the resistance to commercial …

A Cytological Study Of Germinating Aeciospores In The Cronartium Coleosporioides Complex, John A. Christenson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Peridermium harknessii Moore, causal agent of western gall rust, is responsible for deformation, cull and death of pine. In the West it is most serious on lodgepole and ponderosa pines. Seedlings and mature trees may be seriously attacked (Peterson, 1960). Gall rust is easily recognized by its branch galls and trunk cankers. Interest in the disease has fluctuated, but it is considered important enough that government monies support research on the disease in both the United States and Canada.

The Relationship Between Personality As Measured By The Minnesota Multiphasic Personality Inventory And Interest As Measured By The Kuder Preference Record, Robert Glen Knudsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Counselors frequently use batteries of psychological tests in helping students to select appropriate educational and occupational choices. The task of interpreting scores on a battery of tests to students is not at any time a simple undertaking. The trend toward emphasis on the importance of the relationship among the various scores in a battery of tests, has further complicated test interpretation.

Vocational choice theories suggest an interrelationship between vocational interests and personality characteristics. They further suggest that different educational majors and occupations require different types of vocational interest and personality characteristics. Two tests, The Minnesota Multiphasic Personality Inventory (hereafter referred …

A History Of The Utah State University Elementary Teacher Education Laboratory School, R. Eyre Turner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Utah State University has had a university controlled elementary teacher education laboratory school since 1928. In that year, the University, then the Utah Agricultural College, leased the Whittier School from the Logan City Board of Education. The Whittier continued to be used until the summer of 1957 when the newly constructed Edith Bowen Laboratory School became the center of elementary teacher education.

Staff members in the Department of Education and other interested people have repeatedly asked questions about the Laboratory School. They have desired to know what factors prepared the way and stimulated its establishment. They have sought to …
