The Chromosome Number Of Maize, T. A. Kiesselbach, N. F. Petersen

Department of Agronomy and Horticulture: Faculty Publications

The wide-spread interest in the genetics of maize, coupled with the uncertainty as to the number of chromosomes occurring in this species prompted the investigation which is here reported. From a review of the literature it appears that Kuwada (1911, 1915, 1919) is the only worker who has reported extensive counts of maize chromosomes. His results are summarized in table 1. Variations were reported in the number of chromosomes both within and between varieties as well as between different cells of individual plants. He concluded that sweet varieties are usually characterized by having twelve chromosomes, and starchy varieties by having …

Further Studies On The Effect Of Environment On Potato Degeneration Diseases, R. W. Goss, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The identification of potato degeneration diseases in the field is extremely difficult owing to the number of diseases now described, their manifestation on different varieties, the combination of several diseases on the same plant, and the further splitting up of these combinations into separate diseases. The influence of environmental factors in intensifying or inhibiting the symptoms of these diseases also increases the difficulty of diagnosis. In the present investigation the effect of environmental factors has been studied with the purpose of determining the limiting factor or factors in the masking of the symptoms, in the hopes of simplifying a complex …

The Occurrence Of Starch And Erythrodextrin In Maize And Their Segregation In The Pollen Of Hybrids, T. A. Kiesselbach, N. F. Petersen

Department of Agronomy and Horticulture: Faculty Publications

A variety of maize (Zea mays) differing from other known sorts in the texture of its endosperm was described by Collins (1909). The type of endosperm of this variety was designated as “waxy” in contrast with the starchy and sweet types of other maize. It has since been shown by Weatherwax (1922) that the carbohydrate of this waxy endosperm is erythrodextrin which can be distinguished from other carbohydrates by its red color reaction with iodine. It has recently been reported by Demerec (1924) and Brink and MacGillivray (1924) that this carbohydrate is also present in the pollen of …

Color, Countee Cullen

Electronic Texts in American Studies

Poet, playwright, novelist, graduate of DeWitt Clinton High, New York University, and Harvard University, Countee Cullen (1903–1946) emerged as a leading literary figure of the Harlem Renaissance. Color (1925), his first published book of poetry, confronts head-on what W.E.B. DuBois called “the problem of the 20th century—the problem of the color line.” The work includes 72 poems, such as the following:

Incident (For Eric Walrond)

Once riding in old Baltimore,
Heart-filled, head-filled with glee,
I saw a Baltimorean
Keep looking straight at me.

Now I was eight and very small,
And he was no whit bigger,
And so I smiled, …

Better Sires -- Better Stock: Build Better By Breeding, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Economy and logic indicate that the most satisfactory method of obtaining higher-yielding dairy cattle is to breed them. Nebraska raises the feeds - corn, oats and alfalfa - that will grow dairy cattle and can raise them as cheaply as any region. The method is simple. Use purebred dairy sires on the present cows. By the use of good purebred dairy sires great improvement can be obtained in a single generation.

Control Equipment For The Study Of The Relation Of Environment To Disease, George L. Peltier, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The investigation of certain plant disease problems in Nebraska has necessitated the study of the relation of various environmental factors to these diseases. The control of these environmental factors in the greenhouse studies has been obtained by the use of previously described apparatus or their modification and adaptation, along with new methods which have been devised to meet the needs of these investigations. In view of the widespread interest in the subject of environmental control for experimental studies, it was deemed advisable to present briefly the methods now in use in this department in the hope that the information may …

Xx. The Term "Communal", Louise Pound

Department of English: Faculty Publications

I. The Doctrine of Communal Origins

The period following the French Revolution was deeply interested in "the people" as a mass conception, in all that belonged to them and all that they created. It was in this period that theorists on the origin of law, customs, religion, language, literature--particularly the folk-song and the folk-tale--liked to advocate the doctrine of spontaneous, unconscious growth "from the heart of the people," as the phrase went. Such conceptions of origin had their critics from the first; but they remained more or less orthodox throughout the nineteenth century, and they still have foothold in both …

Potato Wilt And Stem-End Rot Caused By Fusarium Eumartii, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present study was undertaken to obtain more information regarding the pathogenicity of Fusarium eumartii and to compare its action with F. oxysporum, in order to distinguish between and to determine the relative importance of the diseases produced by these two organisms. An effort was also made to explain the many negative results of isolation studies reported by various investigators, as well as the inconsistent results often reported in studies of the transmission of wilt by infected tubers. Investigations dealing with the effect of certain environmental conditions on the occurrence of the disease were also undertaken. All of the …

Absorption Of Nutrients From Subsoil In Relation To Crop Yield, John W. Crist, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Investigations of the development of root systems of native and crop plants have been pursued for a number of years at the University of Nebraska. The gradual intensification of this work has led to a type of experimentation designed to discover the nature of the activities of roots at great depths in relation to absorption of water and nutrients. In the present investigation the effects of absorption of nutrients from deep levels upon quantity and quality of yield were determined. Studies on the amounts of water and nitrates removed by crops from various soil levels were begun in i919, but …

Range And Pasture Management, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Sampson's range and pasture management is an excellent example of the application of the principles of ecology to the solution of economic problems. In grazing experiments it is of equal importance to know what is happening to the stock and to the vegetation. This emphasizes the fact, which ecologists are coming more and more to recognize, that animals, both wild and domesticated, have a proper place in the environment and that they play an important role in modifying the vegetational development. This volume consists largely of first-hand information obtained by the author during fifteen years of intensive pasture investigations for …

Direct Measurement Of Water Loss From Vegetation Without Disturbing The Normal Structure Of The Soil, J. E. Weaver, John Crist

Department of Agronomy and Horticulture: Faculty Publications

One of the most serious objections to the usual method of determining the water losses from plants is the almost universal use of containers which are quite too small to accommodate the normal development of the root system. But even where containers of sufficient size to overcome this obstacle are employed, the plants are grown in a mass of soil which has been at least fairly recently screened, mixed, aerated and watered and thus its structure is wholly unlike that which occurs in nature. This difference has been noticed for a number of years in connection with investigations of root …

Effect Of Environment On Potato Degeneration Diseases, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

During recent years much of the investigational work on the degeneration diseases of the potato has been directed toward the separation and identification of a number of diseases formerly grouped under the general names of mosaic, leaf roll, and "running out". Extensive studies have also been made on methods of transmission, host range, overwintering and the identification of the evasive causal factor. Investigations of this type, however, have progressed slowly because of the necessity of developing new methods of research, because of the complexity of the problem, and because of the lack of knowledge regarding the causal factors. Meanwhile there …

The Hemotoxins Of Intestinal Parasites: A Critical Summary With Notes Of Some Cases, Joseph Mellick Leidy Ii

Harold W. Manter Laboratory of Parasitology: Library Materials

The mechanical and reflex disturbances produced by animal parasites in the intestinal canal and other organs of the body have long been recognized by pathologists and clinicians. The researches of economic parasitologists and the occasional reports by clinical observers indicate the presence of other factors deserving of further investigation. That certain parasitic worms secrete substances that effect the blood of their hosts deleteriously has been shown conclusively by the researches of Tallqvist, Schwartz, Schaumann and others. The broad tapeworm of man which is known to produce severe anaemia contains a hemolytic agent according to the experiments and researches of Schaumann …
