A Study In The Metabolism Of The Adult Honey Bee, M. D. Farrar

Electronic Theses and Dissertations

The study of metabolism in the higher forms of life has been carried on for many year and much has been found out that has been of great importance in understanding the way things live and grow. It has been only in the last few years that attention has been given to this phase of the work in insects. The extensive work that has been carried on concerning metabolism in men and animals is the basis for the more recent researches on the lower forms including the microorganisms. Before this work could be carried out on the small forms it …

The text is intended to give the present status of the projects under consideration and to record the changes and additions since the last report.

The Differential Reaction Of Strains Within A Variety Of Wheat To Physiologic Forms Of Puccinia Graminis Tritici, T. A. Kiesselbach, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Black stem rust of wheat (Puccinia graminis tritici (Pers.) Erikss. & Henn.), which occurs in Nebraska and thruout most of the wheat producing regions of the world, is of a composite nature, in that it consists of a number of physiologic forms which can be determined by their action on different varieties of Triticum species, as shown by Stakman and Levine. The ordinary commercial variety of wheat may likewise be regarded as a mixture, in that it consists of numerous strains, which differ in some more or less important characteristics, as has been frequently indicated in the literature concerning …

The Immediate Effect Of Gametic Relationship And Of Parental Type Upon The Kernel Weight Of Corn, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This investigation to determine the relation of the kernel weight of corn to the source of pollen with which it was fertilized has been made to answer several questions of both practical and technical interest: (1) To what extent is kernel weight affected in the current crop by the "breadth of breeding" or the gametic relationship? (2) What is the relation of the diversity of parental type to the immediate effect of foreign pollen upon the kernel weight of corn? (3) Is the immediate effect of cross-fertilization upon the kernel weight of sufficient importance to justify the annual mixing of …

Alfalfa Investigations, T. A. Kiesselbach, Arthur Anderson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of these alfalfa investigations has been to determine the relation of variety, source of seed, and cultural practice to the yield and quality of hay produced. Due to the high initial cost of seeding, the inconvenience and wastefulness of losing a stand prematurely, and the superiority of properly-made hay, an understanding of these relationships is very important.

Studies On The Ascaris Lumbricoides, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The Ascaris lumbricoides, in one phase or another, has attracted the attention of parasitologists for many years, and during the last decade this parasite has been studied by a large number of investigators. The recent observations have been, to a great extent, directed along one line, the study of its life history. These investigators have established two important points: (a) That the life history of Ascaris is more complex than was supposed, as it has been found that a vasculo-pulmonary circuit of the larvae is necessary before they settle down in the intestine, where they develop to the adult …

Studies On The Ascaris Lumbricoides, Harry Mathias Martin

University of Nebraska-Lincoln Extension: Historical Materials

The Ascaris lumbricoides [roundworm], in one phase or another, has attracted the attention of parasitologists for many years, and during the last decade this parasite has been studied by a large number of investigators. The recent observations have been, to a great extent, directed along one line, the study of its life history. These investigators have established two important points: (a) That the life history of Ascaris is more complex than was supposed, as it has been found that a vasculo-pulmonary circuit of the larvae is necessary before they settle down in the intestine, where they develop to the adult …

Nutrient Requirements Of Growing Chicks, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of our experimental work was to establish if possible certain principles of poultry nutrition, permitting later a better combination of natural feedstuffs with the highest growth efficiency.

Circular No. 62 - Summary Of Publications

UAES Circulars

Circular No. 62 contains a summary of publications of the Utah Agricultural Experiment Station issued since September 1925. The publications of this Station are no longer sent to a general mailing list (except in the case of libraries), but are sent. only on request. Therefore, copies of any of the publications listed will be sent without charge to those requesting them as long as the supply is available. However, in the case of abstracts of scientific and technical papers the supply is very limited and the requests for these should therefore be limited as far as possible only to those …

Grazing Periods And Forage Production On The National Forests, Arthur W. Sampson, Harry E. Malmsten

Aspen Bibliography

Stockmen in the West have always had confidence in the adequacy of the native forage crop to provide pasturage for their livestock. Indeed, under normal climatic conditions this enormous natural resource has not failed the grazier, except where it has been called upon to meet unreasonable demands. The productivity of the range has declined sharply, however, wherever the requirements of plant growth have been disregarded for many years in succession. Where there has been too early or too frequent and to heavy grazing, undue trampling, or some other unsatisfactory feature of range use, the results have been uniformly bad. Many …

The Segregation Of Carbohydrates In Crosses Between Waxy And Starchy Types Of Maize, T. A. Kiesselbach, N. F. Petersen

Department of Agronomy and Horticulture: Faculty Publications

The purpose of this paper is to report the Mendelian segregation of waxy and starchy carbohydrates in both the sporophytic and gametophytic generations of maize. This is of especial genetic interest because the counts of segregate waxy kernels have very commonly been short of the expected numbers, although this character appears to be a simple Mendelian recessive. Collins (1909) was the first to point out the physical difference in the endosperm of waxy and ordinary starchy varieties.

While the exact difference in their chemical nature has not been established, Weatherwax (1922) considered that the waxy carbohydrate was erythrodextrin because of …

Turkey Production, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Whatever problems turkey production presents, lack of demand for roast turkey is not at this time one of them. Turkeys rate so high in popular esteem that very rarely indeed do prices fall below that of dressed chickens and usually the best grades are 12 to 15 cents per pound higher during the holiday season. The world of commerce has become quite complex but the consuming public still has one clear way of speaking to producers. In the language of the dollar we are apparently being asked to raise more turkeys.

The Natural Vegetation Of Ohio. Iii. Plant Succession, Paul B. Sears

Papers in Ecology

In the preceding papers of this series (1) it has been shown that within the glaciated area the physiographic results of glaciation offer the best general key to the pattern of natural vegetation. The results of glaciation, in turn, have been largely influenced by preglacial conditions.

In analyzing the composition of the natural vegetation of Ohio certain groups of associations were distinguished, to wit, Prairie, Ash, Oak, and Beech. Each group includes several related classical associations as described by Cowles (2) and others.

Bulletin No. 197 - The Pear Leaf Blister Mite As An Apple Pest, I. M. Hawley

UAES Bulletins

The blister mite is a pest of foreign origin, that has been in the United States for many years. It was introduced into this country, probably from Europe, sometime before 1872, and by 1894 it was rather general in its distribution thruout the United States and Canada. At the present time this mite is a serious pest of apples in many of the fruit-growing sections of Western America. The blister mite was first reported in Utah by Hedrick as early as 1898. During the last few years it has been abnormally abundant in some parts of Utah.

Bulletin No. 196 - The Fruit Tree Leaf Roller And Its Control By Oil Sprays, I. M. Hawley

UAES Bulletins

When the fruit tree leaf roller is present in large numbers in an apple orchard it i the most destructive apple insect in the state. Fortunately, it is not a pest of general occurrence. Tho this insect is known to occur from Cache Valley south to Beaver, serious losses from its ravages have been restricted to occasional orchards within the infested territory.

The Preparation Of Laboratory Specimens As An Aid To The Diagnosis Of Animal Diseases, L. Van Es, L. V. Skidmore

Nebraska Agricultural Experiment Station: Historical Circulars

Many problems in connection with animal diseases require for their solution the application of methods which can only be undertaken in properly equipped laboratories. This ordinarily involves the collection, packing, and shipping of samples of specimens. The manner in which this is done is a most important factor and to a very large extent is responsible either for the success or for the failure of the undertaking. The discussion of the subject to which the following pages are devoted is taken in hand in the hope that it may provide guidance to the veterinarians and others who may have occasion …

The Evaluation Of The Dairy Cow, George Gardner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The accurate appraisal of property is in a great many cases a difficult task. A savings account in a bank may be evaluated with high precision. A business building in a large city may bring in returns sufficiently steady and permanent so that a careful appraiser with a reasonable knowledge of depreciation losses to be anticipated might fix a value without very much error.

Bulletin No. 195 - Field Studies Of Sugar-Beet Nematode, George Stewart, A. H. Bateman

UAES Bulletins

The sugar-beet nematode has now become of importance in Utah. It occurs in spots in practically all of the older beet-growing districts and in a few parts of the state in much larger areas. The intensity of infestation varies from mere traces to nearly complete occupation. One of the areas of severe infestation in Utah on a large area is in the Lewiston district, of northern Cache Valley. The survey here reported was undertaken in order to find the extent of nematode infestation in Cache Valley and the possibility of its control by ordinary cultural practices.

Correlated Inheritance In Wheat, George Stewart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the rediscovery of Mendel's law in 1900, there have been many studies of inheritance in wheat. Of these rather numerous investigations, however, only a few have consisted of correlated studies of various characters on the same plant.

Inheritance of awns and of spike density have received some attention but the studies have hardly more than indicated the problem. Both have been thought by some to be rather simple in their inheritance, and in some crosses without doubt such is the case, but lately there has come a recognition of considerable complexity.

Density. As here used, "density" refers to …

Correlation Studies In Wheat, Joseph Reed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Considerable work has been done by plant breeders and investigators in the study of individual plant characters, but only a few have attempted to work out correlations between characters in crop plants. One reason for this seems to be, that many investigators have felt that correlation studies were of very little practical value. This attitude was due perhaps to the interpretation given correlation data, especially the nature of the casual agency or agencies to which the correlation was attributed. Most of our plant breeders however, have been too busy working on experiments with single characters and have given little or …

The Spindle-Tuber Disease As A Factor In Seed Potato Production, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The lines of experimentation that supplied the data herein reported, stated in very general terms, were as follows: (1) Tuber-line selection studies (2) Relation of environmental conditions to seed-potato production (3) Seed-potato strain trials of certified and uncertified stock (4) Spindle-tuber transmission experiments. Most of these general lines of experimentation will not be completely discussed as a unit in any one part of the bulletin. For the sake of clarity, consecutive thought, and elimination of repetition, data will be selected from any experiment for insertion and discussion under the most logical heading in any part of the bulletin. Unless otherwise …

The Natural Vegetation Of Ohio Ii. The Prairies, Paul B. Sears

Papers in Ecology

It is well known that many treeless areas existed in Ohio before white settlement. These areas, of various ecological character and usually restricted in size, were in a few cases fairly extensive—embracing from fifty to one hundred square miles. The term "prairie" was rather generally applied to them, although more exact terms were not wanting. Like the various forest associations, these treeless areas have played an important role in influencing industrial and cultural phases of human life in Ohio (1). The present paper is an attempt to reconstruct such areas, now destroyed or obscured by secondary successions induced by white …

The Effect Of Alternate Freezing And Thawing On Impermeable Alfalfa And Dodder Seeds, A. R. Midgley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is surprising to know the small amount of work that has been done on alternate freezing and thawing of seeds. Many experiments, however, have been conducted to see the effect of very low temperatures on seeds and to notice the effect it had on their vitality. Some experimenters subjected seeds to temperatures as low as liquid hydrogen with very interesting results but in very few cases, if any, was the effect of alternate freezing and thawing studied.

The work that follows deals directly with the effects of alternate freezing and thawing on impermeable seeds of alfalfa and of dodder. …
