Taxonomix Study Of The Betulaceae And The Fagaceae Of Milwaukee County And Vincinity, Chalres A. Guenther Jun 1933

Taxonomix Study Of The Betulaceae And The Fagaceae Of Milwaukee County And Vincinity, Chalres A. Guenther

Bachelors’ Theses

The study of the Betulaceae and the Fagaceae in Milwaukee County and the immediate vicinity, taxonomically and from the standpoint of distribution presents an interesting problem. The family Betulaceae (Birch Family) comprises 11 species and 3 varieties, 8 species of which are arborescent. One genera is sometimes referred to as being arborescent in this vicinity, but since the author does not consider a lower growing shrub arborescent, he has excluded it from the classification of trees but has in the following discussion treated it as a shrub. The family Fagaceae (Beech Family) which comprises 8 species of which one is …


The Native And Cultivated Gymnospersm Of Eastern Wisconsin, Mary Stapleton Jun 1933

The Native And Cultivated Gymnospersm Of Eastern Wisconsin, Mary Stapleton

Bachelors’ Theses

Since the late years of the nineteenth century, botanists have grouped all seed-bearing plants into two main divisions, those with no seed cases, that is with naked seeds, end those the seeds of which are enclosed in a husk, pod, or other covering. The former are Gymnosperms; the latter Angiosperms.


Study Of The Tissues And Tissue Development In The Leaf And Stem Of Lycium Halifmifolium, L., Charles A. Troxel Jun 1933

Study Of The Tissues And Tissue Development In The Leaf And Stem Of Lycium Halifmifolium, L., Charles A. Troxel

Bachelors’ Theses

The Matrimony-vines are shrubs with usually spiny branches, rigid in some species, slender and arching or procumbent in others, with small and rather narrow, usually grayish green leaves, and dull-colored whitish, purplish, or violet flowers and scarlet, rarely yellow or black, berries. Most of the species are tender but Lycium halimlfollum, L. chinense, and also Lycium turcomanicum and L. ruthenlcum are hardy and thrive in the north temperate regions.

Inheritance Of Resistance To Loose Smut (U. Tritici) In Certain Wheat Crosses, Bion Tolman May 1933

Inheritance Of Resistance To Loose Smut (U. Tritici) In Certain Wheat Crosses, Bion Tolman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During recent years the principles of Mendelism have been used extensively in the production of the new types of plants possessing resistance to various diseases. Results of this mode of attacking the disease problem have been very favorable. Old varieties are gradually giving way to newer types equal to or exceeding in quality and productivity as well as possessing resistance to one or more diseases.

Loose smut (U. tritici) in wheat, while not as serious a problem in Utah as the covered smut (T. tritici), according to Tapke (14) has caused an average annual loss of between 50,000 and 100,000 …


Bulletin No. 241 - Peach Harvesting Studies, F. M. Coe Apr 1933

Bulletin No. 241 - Peach Harvesting Studies, F. M. Coe

UAES Bulletins

The purpose of the four seasons' study of maturity indexes of Elberta type peaches, made in Utah during the years 1926, 1928, 1929, and 1932 and presented in this publication, was to determine more accurately the best stage of maturity of peaches for distant shipment. In general, the procedure was: (1) To record color, pressure test, and other maturity indexes of fruit from trees under various conditions of culture, age, and vigor; (2) to classify the fruit by size and ground color; (3) to store under conditions comparable to refrigerated shipment to market; and (4) to record the appearance, quality, …

The Relative Susceptibility Of Alfalfas To Wilt, George L. Peltier Apr 1933

The Relative Susceptibility Of Alfalfas To Wilt, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Except for alfalfa seed originating from a few old fields of Turkestan and Ladak, all varieties and strains now grown for commercial seed production in the United States, so far tested, have proved susceptible to wilt. All seed lots tested from South America (Chile, Argentina, and Uruguay), Europe (France, Spain, Portugal, Germany, Hungary, Italy, Roumania, and Ukranian S.S.R.), Africa (Morocco, Algeria, and Abyssinia), and Asia (Palestine, Manchuria, China, Korea, and Chinese Turkestan) were found to be susceptible to wilt. All seed lots of Turkestan origin so far tested are as resistant as Hardistan, or more so. Seed samples from the …

The Latex System In The Root Of Taraxacum Officinale, Eleanor Kelton Evenson Jan 1933

The Latex System In The Root Of Taraxacum Officinale, Eleanor Kelton Evenson

Electronic Theses and Dissertations

In 1930 Mr. Emil Madsen of this laboratory began some experimental work upon the roots of dandelions, for the purpose of determining the means by which a dandelion root, which has been cut off below the surface of the ground, regenerates new shoots. He found that such roots form adventitious buds in exposed pericycle and secondary phloem. Several such buds may be formed in a single root. They grow and appear above the ground as leafy shoot.

The Identification Of The More Important Prairie Hay Grasses Of Nebraska By Their Vegetative Characters, F. D. Keim, G. W. Beadle, A. L. Frolik Dec 1932

The Identification Of The More Important Prairie Hay Grasses Of Nebraska By Their Vegetative Characters, F. D. Keim, G. W. Beadle, A. L. Frolik

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is convenient and sometimes necessary to identify the grasses in their vegetative stage of growth. This is especially desirable in a study of the vegetation of native hay meadows and permanent pastures. This key is prepared as a guide in the identification of the more important prairie hay grasses of Nebraska. The meadows are often harvested before the floral parts of many of the grasses appear. If it is desired, therefore, to study the botanical composition of the native meadows, it becomes necessary to rely on identification of many of the grasses by means of vegetative characters.

Bulletin No. 242 - Drainage Of Land Overlying An Artesian Ground-Water Reservoir: Progress Report, O. W. Israelsen, W. W. Mclaughlin

UAES Bulletins

Certain tracts of land in the West formerly used to produce grain and forage crops now produce only pasture grasses of comparatively low quality because of the water-logging and alkali accumulation which has occurred since irrigation was begun. Other tracts now producing only light crops of wild hay probably would produce profitable crops of alfalfa and clover, provided the water-table were lowered and the water-logged and alkaline condition of the soil removed. Still other areas are almost wholly nonproductive because of the concentration of excessive quantities of harmful alkali salts.

Knowledge concerning (1) the causes of water-logging, (2) economical methods …


Bulletin No. 239 - Wet Beet Pulp Compared With Corn Silage In The Dairy Ration, George Q. Bateman, George B. Caine Nov 1932

Bulletin No. 239 - Wet Beet Pulp Compared With Corn Silage In The Dairy Ration, George Q. Bateman, George B. Caine

UAES Bulletins

Wet beet pulp coming as a by-product from the sugar-beet industry in Utah is fed in varying amounts to dairy cows. Corn silage is also used to make up part of the dairy ration. Conflicting statements as to the value of the one feed as compared to the other indicated the need of more knowledge as to the value of pulp as compared to silage in the dairy ration. For this reason a study of the problem was initiated in February, 1926.

Bulletin No. 237 - Panguitch Livestock Experimental Farm Progress Report, B. F. Hulme Oct 1932

Bulletin No. 237 - Panguitch Livestock Experimental Farm Progress Report, B. F. Hulme

UAES Bulletins

The Panguitch Experimental Livestock Farm is located three miles north of Panguitch, the county seat of Garfield County. Prior to 1909 it was held by the United States as an Indian school. In 1909 the United States Congress transferred title to the State of Utah. Two years later, in 1911 , the Utah Legislature decided that this property should "be used as an experiment station in connection with the Agricultural College of Utah ...", and control was vested in the Board of Trustees of the Utah State Agricultural College.

The Nature Of Resistance In Alfalfa To Wilt (Aplanobacter Insidiosum L. Mc.), George L. Peltier, F. R. Schroeder Oct 1932

The Nature Of Resistance In Alfalfa To Wilt (Aplanobacter Insidiosum L. Mc.), George L. Peltier, F. R. Schroeder

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Alfalfa wilt was first discovered in 1924 in southern Wisconsin and northern Illinois. The causal organism, Aplanobacter insidiosum, was later described by McCulloch. Since that time wilt has been reported from most of the alfalfa-growing sections of the United States and in some states it has been responsible for a rapid decrease in the acreage of alfalfa. During the past three years a number of investigators have found that certain alfalfas are somewhat resistant to wilt, whereas others are very susceptible. At the Nebraska station the results to date indicate that all common and most variegated alfalfas are very …

Root System Of Quercus Macrocarpa In Relation To The Invasion Of Prairie, J. E. Weaver, Joseph Cramer Sep 1932

Root System Of Quercus Macrocarpa In Relation To The Invasion Of Prairie, J. E. Weaver, Joseph Cramer

Department of Agronomy and Horticulture: Faculty Publications

Invasion of trees into grassland is primarily a phenomenon of plant competition. It involves the relation of the invaded and the invader to light and other atmospheric factors of the habitat, both physical and biotic. But perhaps even to a greater degree the edaphic factors, and especially water in dry climates, are concerned. Consequently to understand the reasons for plant distribution and the changes resulting from natural successions, a knowledge of the parts of the plants underground and of the interrelations of the root systems is of fundamental importance.

The great tension zone or ecotone between the deciduous forest formation …


Bulletin No. 236 - The Manufacture Of Cheese From Soft-Curd And Hard-Curd Milks, R. L. Hill, A. C. Merrill Aug 1932

Bulletin No. 236 - The Manufacture Of Cheese From Soft-Curd And Hard-Curd Milks, R. L. Hill, A. C. Merrill

UAES Bulletins

Little investigational work has been conducted on the effect of the hardness of curd of milk on the quality, quantity, and commercial value of cheese.

In July 1930, a preliminary report from the Utah Agricultural Experiment Station was made on these researches. This report indicated that for the manufacture of cheese hard-curd milk was far superior to soft-curd milk. This research is a continuation of that project.

Hard- and soft-curd milk used in the tests reported was obtained from Holstein cows. The fat content of each milk was practically the same. While the difference in curd hardness between the soft- …
