Absorption Of C14 Labeled Sucrose By Nectaries, Cecil Wright Lefevre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the early Eighteenth Century the significance of nectar secretion has been debated. Some have reasoned that it is reabsorbed into the plant and used as energy for the developing embryo while others believe it is a waste product which attracts pollinating insects.

It has been suggested (Brink and Cooper, 1947) that the nutrient supply to developing ovules is a major factor in the development of seed. Also, alfalfa fields pollinated by pollen-collecting bees produce greater seed yields than those pollinated by nectar collectors (Bohart, Nye, and Levin, 1955). It is a well-known fact that more flowers are tripped by …

An Evaluation Of The Salt Tolerance Of Particular Varieties, Strains, And Selections Of Three Grasses And Two Legumes, Farrel John Olsen Jr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In arid and semiarid areas in the Western United States, soluble salts tend to accumulate in the soil in amounts harmful to crop production. A considerable portion of this land cannot be reclaimed due to the poor quality of permeability of the soil. Therefore, the wise selection of crops that will produce satisfactory yields on these soils in necessary.

The salt tolerance of many crop plants has been investigated; however, more information is needed on the relative salt tolerance of varieties, strains, and selections. Such information will permit the selection and development of varieties and strains of crop plants which …

Consumer Preferences And Attitudes Toward Butter And Advertising In Brookings And Madison, South Dakota, Paul M. Williamson

Electronic Theses and Dissertations

The basic purpose of this study was to seek means of improving the incomes of dairy farmers through the development of better markets for butter. In line with this, three major hypotheses were tested. The hypotheses were: (1) a sufficient proportion of consumers in Brookings and Madison prefer cultured butter to make it feasible to develop a market for it, (2) consumption of cultured butter can be increased by sales promotion, (3) development of a market for cultured butter will increase total butter consumption.

A Preliminary Investigation Of The Role Of Selenium In The Growth Of Stanleya Pinnata, Richard F. Nelson

Theses and Dissertations

Stanleya pinnata has been identified as an indicator plant for seleniferous soils. The apparent limitation of its distribution to seleniferous soils suggests that selenium may play an essential role in this species. This study is a preliminary investigation of the role of selenium to Stanleya pinnata. When fully ripe, seeds germinated readily. Concentrations of selenium of 100 parts per million and 1000 parts per million retarded germination. Seeds germiuated in lower concentrations were not affected which was probably due to the selenium content of the seed itself, being greater than in the germinating media. Stanleya pinnata plants were grown from …

Chemosynthetic Microorganisms In Leaching Sulfide Minerals, A. Keith Jameson

Theses and Dissertations

This investigation showed that a single bacterium was capable of sulfide oxidation in exposed ore bodies. This single bacterium was isolated and characterized. It exhibited different characteristics than any previously known organism. It was found to be a chemosynthetic autotroph. An optimum nutrient concentration was determined for pyrite oxidation. The nutrient concentration was determined for pyrite oxidation. The nutrient contains only a source of phosphate and nitrogen. Urea was found to be a better source of nitrogen than ammonium sulfate which had previously been used. The effect of various organic compounds on the oxidation of pyrite was observed. Glucose and …

The Measurement Of Physical Properties Of Field Soil, Wilbur Sloat

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the beginning of soil tilled agriculture, there have been many controversies as to the proper kinds and amounts of soil tillage required to establish and produce a crop. These controversies have ranged far and wide between farmers, extension service personnel, agricultural specialists, in fact almost every person connected with agriculture has his own unique concept of what constitutes proper tillage. The concepts vary widely from a no tillage program, for certain perennial row crops, to the extreme dust mulch program.

The Relative Saponin Content Of Alfalfa Varieties In Utah As Measured By Chick Growth Depression, Morris Dean Wilding

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bloat among ruminants is not new to farmers or scientists. One learns from a Roman author's description of this ailment written in 60 A. D. that the symptoms have changed little since that time. Literature also records that the treatments used today for the prevention and relief of bloat are similar to those prescribed by the early Romans (Anonymous 1954).

A Study Of The Root Rot-Nematode Complex And The Comparative Yield Of 17 Varieties Of Alfalfa In Washington County, Utah, J. Clair Theurer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa is the major forage crop in the state of Utah. It is especially important in Washington County where mild temperatures allow the production of 4 to 5 cuttings each year, and where the dairy industry is increasing.

The Alkali Tolerance Of Tall Wheatgrass, David L. Carter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alkali land occurs adjacent to nearly every extensively irrigated area. Much of this land is too alkaline to produce profitable crops. Each year thousands of acres or land are going out of production because or increasing alkalinity. This presents one or the most acute problem which confronts irrigation agriculture today.

The Effects Of Hunting Season Length On Comparable Pheasant Populations, Temple A. Reynolds

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years sportsmen have speculated that hunting limits pheasant populations. With the abolition of the Pheasant Game Farm program in Utah in 1953, this popular concept gained much impetus with the result that, because of public disfavor to a longer season, a 3 to 5 day season on pheasants is the maximum that has been called in northern Utah and this only in areas classed as "better" pheasant habitat.

In contrast to the short seasons in Utah, pheasant seasons in southern Idaho have been from 8½ to 15½ days long for the past 10 years, and will be even …

Evidence Against The Transmission Of Staphylococci By The Mosquito Culex Tarsalis, John R. Molenda

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Staphylococcal synovitis is a pathological condition of birds involving primarily the wing and leg joints. It is frequently referred to as arthritis, osteoarthritis, bursitis, hock disease, staphylococcosis, and weak leg.

The disease has been reported throughout various parts of the world as having been found in a great variety of avian hosts including pheasants, chickens, pigeons, canaries, geese, ducks, grouse, and turkeys.

Miner (1945) presented results of a survey made on turkey diseases in Sanpete County, Utah, which indicated staphylococcal synovitis to be responsible for the greatest numbers of deaths. His report cites this infection as having been found in …

Green Rot Of Apricot, Abdul Karim N. Alrayis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This disease, also called jacket rot of apricot, was first though to be similar to a disease caused by a fungus found in central California. The Utah disease was first noted in 1953, in the Henry Hall Chinese apricot orchard at North Ogden. It was not very severe in 1953, but in 1954 and 1955 it affected half of the crop. In 1956 the disease could not be found in the orchard. Infection occurred in young green fruit resulting in brown to black necrotic lesions which varied from 1/4 to 3/4 inches in diameter. Infected fruits usually dropped from the …

Studies On The Helminth Fauna Of Alaska. Xxxi. Observations On The Propagation Of The Larval Echinococcus Multilocularis Leuckart, 1863, In Vitro, Robert L. Rausch, Virginia Jentoft

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Larval reproduction in Echinococcus multilocularis Leuckart, 1863, takes place through the proliferation of exogenous secondary vesicles (Rausch, 1954). In some species of host this process appears to be continual, extending over a long period of time with little tendency for self-limitation. Consequently, the growth characteristics of this larval cestode are such that it would seem well suited to culture in vitro.

Gyrodactylus Eucaliae N. Sp. (Trematoda: Monogenea) From The Brook Stickleback, Eucalia Inconstans*, Glenn L. Hoffman, Francis M. Ikezaki

United States Fish and Wildlife Service: Publications

A new species of Gyrodactylus was observed on the skin, gills, and fins of the brook stickleback from the English Coulee, Grand Forks, North Dakota during the summers of 1953-1955. Host-specificity is usually striking in the monogenetic trematodes and since this parasite was not observed on any other species of fish from this body of water or the nearby Turtle River, it was studied in detail and is here described as a new species, G. eucaliae.

New Polychrome Methods In Microtechnique, Celestino Nera Macabales

University of the Pacific Theses and Dissertations

When the writer took an introductory course in Microtechnique in 1954-55, he was impressed by the inadequacy of some microtechnical procedures recommended in triple staining, and he felt disappointed and discouraged by the consistently inferior results. He resolved to attempt modifications or to develop a new technique which could be relied upon to achieve anticipated results. This is a report on two years of efforts to develop a simple dependable technique in polychrome staining for histological studies. The writer feels that the results are of importance to students and teachers of biological science and to microtomists. The herein proposed technique …

The Rabbit : An Illustrated Anatomical Guide, Edwin Chin Jr.

University of the Pacific Theses and Dissertations

This study on the anatomy of the rabbit was based on dissected material from the biological laboratories of the College of the Pacific. Because of existing errors in many of the present references to rabbit anatomy, the guide was prepared to meet the expressed need for a concise, illustrated outline of basic anatomy of the rabbit which might be used by students in an introductory course in mammalian or human anatomy. Since it is assumed that the guide would be supplemented by a dissection manual, syllabus, or textbook, textural material of such an outline is presented here in outline form.
