Relation Between The Development Of Root System And Shoot Under Long- And Short-Day Illumination, J. E. Weaver, W. J. Himmel Oct 1929

Relation Between The Development Of Root System And Shoot Under Long- And Short-Day Illumination, J. E. Weaver, W. J. Himmel

Department of Agronomy and Horticulture: Faculty Publications

Relatively few investigations have been made to determine the factors which affect the relation of the growth of roots to tops. A more exact knowledge of the relations between aerial and subterranean plant parts and the degree to which these may be modified through cultural practices is of great scientific and practical importance. Extensive investigations have shown that plants exhibit marked specific and varietal differences with respect to relative development of roots when grown under the same environmental conditions. Intensive studies on the growth of wheat by Weaver, Kramer, and Reed (20) and of certain other plants by Crist and …

Bulletin No. 212 - Studies On The Morphology Of The Beet Leafhopper, G. F. Knowlton Jul 1929

Bulletin No. 212 - Studies On The Morphology Of The Beet Leafhopper, G. F. Knowlton

UAES Bulletins

The beet leafhopper, Eutettix tenellus (Baker), is one of the most serious insect pests of western North America. Its chief importance is as a vector of the plant disease curly-top, which it transmits to beets, tomatoes, beans, melons, and many other agricultural plants. The virus apparently is introduced into the plant during the process of feeding, and is responsible for the frequent and often enormous losses to the sugar-beet growers and sugar manufacturers of the west. Apparently, the virus multiplies and remains active in the body of a leafhopper for some time, making it possible for the insect, after once …


Bulletin No. 213 - Food Habits Of Utah Farm Families, Almeda Perry Brown Jul 1929

Bulletin No. 213 - Food Habits Of Utah Farm Families, Almeda Perry Brown

UAES Bulletins

This report is merely an attempt to set forth the findings of the investigation without making claim to their being conclusive except for the families included in the study. While the study was carried into a relatively large portion of the state, the records are too few in number for any claim to be made that they represent community food conditions. It is believed, however, that the records which form the basis of this report are representative of the food situation in the homes from which they come.

Bulletin No. 211 - Silage Corn Varieties For Utah, George Stewart, A. L. Wilson Jun 1929

Bulletin No. 211 - Silage Corn Varieties For Utah, George Stewart, A. L. Wilson

UAES Bulletins

Utah is rapidly developing an important dairy industry. In addition to homegrown hay and grain, there must be some form of succulence. Pasturage is the common way of furnishing fresh feed in summer. In certain regions, silage and beet pulp are the winter forms. With a scarcity of beet pulp, silage corn is likely to be an important crop in the Great Salt Lake and Utah Lake Valleys, where corn does well. The data presented in this publication are related to the choice of a corn variety for ensilage.


Circular No. 77 - Measurement Of Irrigation Water, George D. Clyde Jun 1929

Circular No. 77 - Measurement Of Irrigation Water, George D. Clyde

UAES Circulars

Water is the limiting factor in Utah's agricultural development. In spite of its admitted value the farmer knows less about the measurement of water than about any of the other commodities which he handles. He knows how to measure his land, his crops and his cattle, but he has little conception of how to measure his most valuable asset, viz., irrigation water. The importance of water measurement is not appreciated until the water-supply becomes over-appropriated and users begin interfering with each other's rights. Expensive litigation, which always follow controversies over water, is gradually convincing the farmer that water should be …

The Structure Of The Seed And The Development Of The Seedling Of Symplocarpus Foetidus (L.) Nutt,, John P. Ranzau Jun 1929

The Structure Of The Seed And The Development Of The Seedling Of Symplocarpus Foetidus (L.) Nutt,, John P. Ranzau

Bachelors’ Theses

The first mention of Symplocarpus foetidus (L.) Nutt. is made by John Josselyn in his ''New England rarities discovered in birds, beasts. fishes, serpents and plants of that country" published in 1872, where it is listed with plants such as are "proper to the country and have no name." The subject of his description can readily be discovered from a crudely engraved illustration. "The whole plant scents as strong as a fox" certainly leaves no doubt as to the identity of the plant. The plant has for a long time been of unusual interest to both layman and botanist because …

Bulletin No. 210 - The Mineral Content Of Grains, J. E. Greaves, C. T. Hirst May 1929

Bulletin No. 210 - The Mineral Content Of Grains, J. E. Greaves, C. T. Hirst

UAES Bulletins

It is generally recognized that shrunken, frosted, or smutty grain is inferior to sound, clean, plump grain. Much has been done on the protein content of grain, and the best millers today purchase grain for its protein content. Few give any consideration to its minerals. Yet do two bushels of sound, plump, clean grain of known protein content grown under the same or different conditions, have the same mineral content? If not, it is of importance to both the producer and consumer: to the consumer because it governs the nutritive value of the product; to the producer because it represents …

The Effect Of Treatment With Ethylene Chlorhydrin Upon The Respiration Of Sweet Potatoes (Ipomea Batatas), Leon J. Tyler Jan 1929

The Effect Of Treatment With Ethylene Chlorhydrin Upon The Respiration Of Sweet Potatoes (Ipomea Batatas), Leon J. Tyler

Electronic Theses and Dissertations

  1. Treatment with ethylene chlorhydrin produced marked results in the respiration of four of five varieties of sweet potatoes tried.
  2. Not all varieties of sweet potatoes respond alike to the same treatment. Porto Rico variety of sweet potatoes did not respond to the treatment.
  3. There was a considerable difference in the amount of CO2 respired by different varieties.
  4. The need for further research here with respect to the specific effect of chemicals upon the cell system becomes apparent and again emphasizes the importance of Biochemistry.
  5. There was possibly an accelerative effect on sprouting due to increased respiratory processes brought about …


A Contribution On The Staminate Flower Of Cucumis Sativus, Kenneth W. Simons Jan 1929

A Contribution On The Staminate Flower Of Cucumis Sativus, Kenneth W. Simons

Electronic Theses and Dissertations

In Heimlich’s recent paper (2) on the staminate flower of Cucumis sativus, the conclusion was reached that the tetrasporangiate stamen was complete while the bisporangiate stamen was only half complete. In Miller’s more recent investigation of Schinocystis lobata (4), the bisporangiate stamen was shown to be complete and the tetrasporangiate stamen double. These opposing points of view suggest the advisability of further investigation in the Cucurbitaceae. Since Heimlich described two separate apical prolongations on each tetrasporangiate stamen and only one on the bisporangiate stamen, it seemed to the present writer that these prolongations might indicate the double and single natures …


The Frequency Of Somatic Mutation In Variegated Pericarp Of Maize, R. A. Emerson Jan 1929

The Frequency Of Somatic Mutation In Variegated Pericarp Of Maize, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

Some years ago (Emerson 1922) the writer announced that in F2 of

certain crosses of variegated with colorless pericarp in maize the heterozygous

individuals changed to self color more frequently than did the homozygous

individuals of the same cultures. No “explanation” of this phenomenon

was then apparent, but later results, though still far from affording

an adequate solution of the problem, have furnished at least a working

hypothesis. The original unpublished paper, with minor modifications,

is given below, under the heading. “Somatic mutations in heterozygous

and in homozygous variegated pericarp.”

Bulletin No. 207 - The Physical Cure Character Of Milk And Its Relationship To The Digestability And Food Value Of Milk For Infants, R. L. Hill Jun 1928

Bulletin No. 207 - The Physical Cure Character Of Milk And Its Relationship To The Digestability And Food Value Of Milk For Infants, R. L. Hill

UAES Bulletins

In the feeding of infants,' cows' milk is the best and most common substitute for human milk. In the feeding of delicate infants, however, considerable difficulty is often experienced from its use. The ideal substitute for mothers' milk has not been found, and most of the clinical effort has been directed towards the modification of cows' milk for infants.

Comparatively little research has been done on the difference in the digestibility and food value of milks from different cows for the infant. It is a well-known fact that the curd of cows' milk forms in a tough mass which varies …


Bulletin No. 206 - Treehopper Injury In Utah Orchards, Charles J. Sorenson Jun 1928

Bulletin No. 206 - Treehopper Injury In Utah Orchards, Charles J. Sorenson

UAES Bulletins

Treehopper injury is a problem that has given many fruit growers in Utah some concern during recent years. These people have observed that their young fruit trees and the twigs and smaller branches of older trees have been attacked during the autumn of each year in a manner that produced numerous cuts which later formed scars. The trees frequently became unthrifty, and more or less deformed and stunted, as a result of these annual attacks.

The investigation reported in this publication was made for the purpose of ascertaining the present status of the treehopper situation in Utah orchards.
