Characteristics Of Manila And Related Soil Series, Flayeh H. Altaie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In many parts of the world soils have been found that have apparently been formed under climatic conditions that no longer exist. In many places in northern Utah in areas associated with ancient Lake Bonneville, deep soils, fine-textured and non-calcareous, have been observed immediately above the highest shore line of the ancient lake. These soils have essentially no free carbonates to depths ranging from 4 to 15 feet, even though they exist on relatively steep slopes. In Davis and Utah Counties, soils having these characteristics have been given the tentative series name, Manila.

Soils studied for this thesis include one …

A Study On The Phenotypic Stability Of Selected Eastern Forage Synthetics Grown Under Utah Conditions, Don J. Heinz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The production of forage seed for use in the eastern United States is a large industry in Utah and other Western States. The development or forage synthetics in the east with production or seed in the west raises the questions “Is there a change in the synthetic when seed is produced under different environmental conditions?” To obtain information relating to genetic stability of grass and legume seed crops produced under various environmental conditions, the USDA-ARS Crops Research Division, Forage and Range Research Branch, Foundation Seed Production Section, set up several experimental plots in the western United States. These are located …

Some Chemical Properties Of The Profiles Of Two Soil Series As Shown By Horizons And By Increments, Verle Q. Hale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil classification in this country is based on the system proposed by Marbut in 1920 (2). This system uses eight criteria, one of which is the chemical composition of the soil horizons. Workers in the field of soil survey are depending more and more upon laboratory data to characterize and differentiate soils not only at the series level but also at higher levels of classification where it may be necessary to establish the presence or absence of critical horizons or characteristics. This was predicted by Robinson (16) when he said that laboratory analysis is needed to give "precise physical meaning …

Linkage Relationships Of Located And Unlocated Genetic Testers In Certain Normal And Translocation Stocks Of Barley, William Ralph Andersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley is an economically important cereal crop throughout most of the world. The study and elucidation of the genetic complex of this plant will add to its extensive usefulness to man, and will also provide valuable information for similar research projects on other crop plants.

The Effect Of Soil Moisture And Fertilizers On Seed Germination, Stephen Dubetz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Failure of viable seeds to germinate results in poor stands and often in lower yields. Some of the more important factors that affect germination of seed are temperature, moisture, aeration, and alkalinity.

Planting of speciality crops under irrigation in southern Alberta, Canada, usually is done when temperature is favourable to germination. However, soil moisture, especially in the seed zone, may not always be adequate - a situation brought about, in part, by the strong winds that prevail in this area. Results at the Experimental Farm, Lethbridge, Alberta, show that irrigated crops respond to phosphorus and nitrogen. During the past six …

Linkage And Inheritance Studies In Barley (Hordeum), Robert E. Heiner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley has had wide acceptance not only as a cultivated crop but also as an excellent source of genetic material. Barley was being used in inheritance studies by Tschermak when he rediscovered Mendel's laws of heredity. Since then barley has become one of the most widely used plants for genetic studies known today.

More than 100 characters have been investigated indicating the relative ease of classification. There are 7 linkage groups corresponding to the 7 chromosomes in which 2 or more characters have been located as reported by Robertson (1939). But Kramer, Veyl, and Hanson (1954), from translocation experiments, suggest …

A Critical Appraisal Of Methods Of Sucrose Analysis In Sugar Beets, Homer M. Lebaron

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although the parent of the present sugar beet was probably known and used before the building of the pyramid of Cheops (22), it was as recent as 210 years ago that Marggraf obtained the first crystalized sucrose from the root. It was 40 years later before Achard claimed its potentialities as an efficient industry. The product rapidly passed from the status of a luxury to a vital necessity, until today sugar beet production receives some protection or preference in every country where sugar beets are grown.

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 …
