An Inheritance And Linkage Study Of Barley With Special Emphasis On Purple Pigmentation Of The Auricle, Devon Lyle Doney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

New and better adapted varieties of crop plants have resulted from the application of the principles of genetics. Fundamental research in the field of barley genetics has helped the plant breeder in developing better varieties for specific uses and adaptability.

Barley is one of the best cultivated crop plants for making genetic studies. It has a wide range of adaptability, exhibits a host of contrasting genetic characters, is a simple diploid with only seven pairs of chromosomes, and all the cultivated species are inter-fertile.

The mode of inheritance of nearly 200 characters has been studied, many of whose genes have …

General And Specific Combining Ability Of Five Alfalfa Clones Including Reciprocal Effects For Seedling Vigor And Seed Yield, Edwin Theodore Bingham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of F₁ hybrids for commercial production of such cross-pollinated crops as corn, sorghum, sugar beets, onions, and pearl millet suggests the feasibility of using this technique for alfalfa. Production of F₁ hybrids of commercial value is dependent on the use of breeding material expressing good combining ability. In order to obtain precise estimates of combining ability for quantitative characters in alfalfa, it is necessary to produce all possible single crosses among a number of parents. The single cross seed required is difficult to obtain due to the vegetative reproduction and isolation required; and, subsequently, limited testing …

Seriousness Of Dodder In Production Of Alfalfa Seed In Millard County, Lloyd Claude Warner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dodder is the common name for the group of plants in the genus Cuscuta. It is a serious weed in nearly all the legume seed producing areas of southern and western United States (5). Dodder is of major economic importance in the production of alfalfa, lespedeza, clover, and of less importance in such crops as flax, onions, sugar beets, and some ornamentals.

In Millard County, which is the most important alfalfa seed producing area in Utah, growers consider dodder one of their worst threats to alfalfa seed production.

A major factor that contributes to the dodder problem in Millard …

Influence Of Compaction And Freezing On The Structure And Permeability Of Some Selected Horizons From Northern Utah Soils, Samir Ramzy Nagmoush

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Frequently, in evaluating plant deficiencies, one considers only those soil factors which are associated with the fertility of the soil-- mainly the levels of phosphorus, potash, nitrogen, and organic matter. A certain level of nutrition is essential for plant growth, but in order for the nutrients to exert their maximum influence on the productivity of the soil, it is equally important that a good soil environment be provided and maintained. A good environment requires that good physical conditions of soil, sir, and water be in balance.

Moisture And Temperature Effects On The Transformations Of Nitrogen From Applied Ammonium Sulfate In A Calcareous Soil, John Keith Justice

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen has commonly been a deficient element in the cultivated soils of the world since the beginning of agriculture. The general acceptance of the practice of using manures as a means of increasing plant growth, as shown by the records of ancient civilizations, attest to this fact. Since the time of von Liebig there has been an increasing awareness of the importance of this deficiency in soils. As a result of a better understanding of the problem and the increasing availability of commercial forms of nitrogen, a rapid increase in the use of nitrogen fertilizers has taken place in the …

James Mellor: English Convert And Handcart Pioneer - A Biography, Edna J. Gregerson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years the descendants of John and James Mellor -- a large family who have made contributions to the cultural and educational activities of their various communities -- have been desirous of preserving for their posterity, and others, a record of the Mellors. Several years ago Amy Mellor Howe initiated the project by compiling and editing the first Mellor History. The foreword in her book wherein she "...hoped that the information and data herein contained may form the nucleus for further research..." served as the incentive to continue the project.

It is planned to incorporate the following biography into …

The Effect Of Fluoride On Glucose Catabolism In Plant Leaves, Cleon W. Ross

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the last few years many studies concerning the effects of fluoride on plants have been made. Several of the experiments have been related to its influence upon respiration of various plant tissues. The effect on respiration appears to be complex.

The Life Cycle And Pathogenicity Of Eimeria Auburnensis, Wayne Norris Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Coccidiosis in cattle is caused by microscopic one-celled sporozoa belonging to the order Coccidia and the genus Eimeria. Coccidiosis is a common disease of young calves that weakens or kills them, but the disease also occurs in older animals. Eleven species have been reported in cattle of the U.S.A.(Davis and Bowman, 1956). Of this number only two species, Eimeria bovis(Hammond et al., 1946) and Eimeria zurnii(Davis and Bowman, 1957) have been proven pathogenic for cattle, but except for Eimeria alabamensis(Davis et al., 1955) no experimental work has been done on other species.

Deviations In Serum Proteins Associated With Eimeria Bovis Infections In Calves And Some Related Immune Reactions, Paul R. Fitzgerald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bovine coccidiosis is a serious threat to the economy of the cattle industry in the United States. In 1954 the United States Department of Agriculture reported that over $10,000,000 was lost annually as a result of mortality and morbidity in cattle due to this parasite (1). These losses alone amounted to more than one fourth of the total loss in cattle due to parasitism.

Influence Of Logging On Douglas Fir Beetle Populations, R R. Lejeune, L H. Mcmullen, M D. Atkins

The Bark Beetles, Fuels, and Fire Bibliography

All species of bark beetles of economic importance prefer to attack freshly-killed host material. Logging slash, wind-throw, and fire-killed timber provide ideal breeding grounds for bark beetles. A few species, mostly in the Dendroctonus group, are able to kill living trees. When beetles in the group, raised in preferred host material, cannot find any or enough freshly-killed trees, logs, or slash to enter, they may attack living trees. In the interior of British Columbia, infestations of the Douglas fir beetle can often be traced to logging disturbance.

A Rational Approach To The Estimation Of Evaporation And Evapotranspiration From Climatological Data, Jerald Emmet Christiansen, B. B. Patil

Reports

Many attempts have been made to derive mathematical expressions relating evaporation and evapotranspiration, or consumptive use, to climatological data. IN the United States, the Blaney-Criddle formula is probably the best known for estimating consumptive use (2 and 3). Blaney (1) has also suggested that this formula is suitable for estimating evaporation as measured with a Weather Bureau pan. Other well known formulas are the Penman formulas (10), the Thornthwaite formula (15) and the Hargreaves formulas (8). Halkias, Beihmeyer and Hendrickson (6) suggest that water requirements of crops can be determined from atmometer data. Lowry and Johnson (() in an early …
