Effects Of Time And Method Of Treatment On Tree Kill And Bluegrass Recovery, J. M. Aikman, E. P. Sylwester

Proceedings of the Iowa Academy of Science

Box elder trees in replicated plots within four seasonal blocks mostly ranged in age from 17 to 24 years, in breast-high diameter from 2 to 8 inches, and in height from 18 to 24 feet. Tree cutting at 3 inches and at 1 foot was done with a chain saw; and a brush killer-fuel oil mixture, at the rate of one quart of concentrate to 5 gallons of fuel oil and one quart to 10 gallons, was applied to the stumps. Resprouting from stumps cut at both heights and in four different seasons was controlled by both concentrations of the …

Yield Components In Oats. Iv. Effect Of Delayed Application Of Nitrogen, Kenneth J. Frey

Proceedings of the Iowa Academy of Science

Three rates of nitrogen fertilization, 20, 40, and 80 pounds per acre, were applied to oats at seeding time and 2, 4, and 6 weeks later. When compared with the seeding data, delaying the application of 20 and 80 pounds of nitrogen caused a decrease in relative grain yields. At the 40-pound rate, increases in relative yields due to applying the nitrogen 2 and 4 weeks after seeding were observed. The yield response to delayed application of 20 pounds of nitrogen per acre resulted from a reduced relative number of seeds per head, while the 80 pound response was due …

Biosynthesis Of Cholinesterase-Inhibitory Substances From Non-Inhibitory Dialkyl Thiophosphates By Plant Tissues, Wallace H. Orgell, Kunda A. Vaidya, Eugene W. Hamilton

Proceedings of the Iowa Academy of Science

Aqueous solutions of the potassium salts of diethyl thiophosphate and diethyl dithiophosphate were applied to intact leaves of the following 10 plant species: alfalfa (Medicago saliva L.), carrot (Daucus carota L.), strawberry (Fragaria chiloensis, Duchesne), American elderberry (Sambucus canadensis L.), velvetleaf (Abutilon theophrasti Medic.), dandelion (Taraxacum officinale Weber), soybean (Glycine max, Merr.), lima bean (Phaseolus limensis Macf.), catnip (Nepeta cataria L.), and Virginia creeper (Hedera quinquefolia L.). After 24 to 72 hours, aqueous homogenates of all species, excepting carrot, inhibited the action of human plasma cholinesterase in vitro. Neither the plant homogenates nor the thiophosphate salts either separately …

Growth Of The Walleye In The Des Moines River, Boone County, Iowa, James C. Schmulbach

Proceedings of the Iowa Academy of Science

Even though the habitat is marginal, a considerable fishery exists for walleyes in the Des Moines River. Tagging studies indicate the annual rate of harvest to be about 10 percent. The size of the population is evidently limited by frequent fish kills due to high water temperatures in the summer and oxygen depletion in the winter. Considerable variation in growth exists within age groups and between year classes. Possible explanations include: (1) sexual differences, especially between fish over four years old; (2) frequent fish kills which result in vacancies in the habitat; (3) low water levels during certain years; and …

The Effects On The Quality And Rate Of Cursive Writing Of A Seven Months Delay In Its Introduction In The Waterloo Schools, Mary Elizabeth Fredrikson

Dissertations and Theses @ UNI

It has been the policy in the Waterloo school system for the past sixteen years to make the transition from manuscript to cursive handwriting during the last six to eight weeks in second grade. The first part of third grade is spent in a review of the formation of the small and capital cursive letters. Cursive writing is taught throughout the remainder of third grade and used as the primary writing tool throughout the grades. The purpose of this study was to investigate how the quality and rate of cursive writing were affected by delaying the starting of instruction in …

A Proposed Guide For Secretaries For Use In Maintaining The Financial Records Of A School Lunch Program, Lavern Elmer Carpenter

Dissertations and Theses @ UNI

One of the greatest advances in reoent years in the area of student health, in both the elementary and secondary schools of our nation. has been the development of the school lunch program. The impetus for this program in the United States came during the year 1933 when the Federal Emergency Relief Administration authorized relief funds for the feeding of school children. At that time many schools throughout the country began serving a hot dish--sometimes a bowl of soup to be eaten with the student's home-packed lunch. By 1934 there were approximately 300,000 school children being served at school.

X-Ray Irradiation Of Soybean Seed As A Technique For Production Of Disease Resistant Plants, John Dunleavy

Proceedings of the Iowa Academy of Science

Hawkeye soybean seeds were irradiated with X-rays at dosage levels of 2,500, 5,000, 7,500, 10,000 and 15,000 r. Irradiation had no effect on germination. Plant height 2 weeks after sowing was greatly reduced at 10,000 and 15,000 r., and morphological abnormalities were common. Fertility was greatly reduced at 15,000 r. When seeds were irradiated at dosage levels of 20,000 to 65,000 r., no plant matured and produced seed when dosage was above 35,000 r. The most obvious effect of high dosage X-ray irradiation of seed was the killing of primary leaves and apical meristems. When tested for resistance to Pseudomonas …

Variations In Mankato Glacial Till And Related Soil Types In Hamilton County, Iowa, Allen R. Hidlebaugh

Proceedings of the Iowa Academy of Science

Soil surveys in Hamilton County, Iowa, have shown a need for the revision of the Clarion and Nicollet soil series to include the fine textured variant soils found there or for the establishment of new series. The results of this study show that sufficient differences exist to warrant the establishment of new series for the fine textured variants of Clarion and Nicollet. They are higher in clay content, have lower chroma in the A horizon, have higher gravel content, have higher bulk density, are firmer in consistence, have finer and better developed structure, and mottling occurs at shallower depths, than …

Changes In Fish Populations And Food Habits Of Yellow Bass In North Twin Lake, 1956-1958, Joe E. Collier

Proceedings of the Iowa Academy of Science

Fish population studies initiated in 1953 indicated that most species were on the increase until the winter kill of 1955. In 1956, populations were below normal; in 1957 there was an increase in most species, followed by a decrease in 1958. Studies during 1953 and 1954 showed that the food of adult yellow bass consisted to a great extent of young-of-the-year yellow bass and gizzard shad, along- with insects. During the summers of 1956, 1957, and 1958, forage fish were of very minor importance in the diet of yellow bass; they fed mainly on immature insects and minute crustacea.

The Contribution Of De Bary To Our Knowledge Of Myxomycetes, G. W. Martin

Proceedings of the Iowa Academy of Science

The slime molds have been known scientifically for over two centuries. Even before Micheli's time, there is record of references to Fuligo, and in 1729 Micheli published recognizable descriptions and illustrations of several genera and species. Other pre-Lipnean botanists studied the group, but it was not until Linnaeus had stimulated interest in things botanical (although, as is well known, he added nothing to our knowledge of the fungi and slime molds) that extensive study was devoted to the group. The work of Batsch, Bulliard, Schrader, Schweinitz and some of their contemporaries gave us a taxonomic basis for the species, while …

Recent Locality Records For Some Iowa Mammals, Emmett Polder

Proceedings of the Iowa Academy of Science

In 1953 the writer published a Checklist of Iowa Mammals with notes on new species and changes in distribution since 1937. At that time it was apparent that much information was lacking on distribution of some species. A few forms were small, retiring, and difficult to collect. A large number were conspicuous fur bearers and game species that had moved into new territory or had escaped notice of systematic mammalogists in the past. Some larger mammals for which considerable distribution data were lacking included the otter, grey fox, wildcat, woodchuck, chipmunk, red squirrel, grey squirrel, and white-tailed jack rabbit. Most …

The Fish Population Of A Southern Iowa Artificial Lake, James Mayhew

Proceedings of the Iowa Academy of Science

Lake Macbride, a 138-acre state-owned artificial lake in Johnson County, was drained in the fall of 1956 to permit reconstruction of the dam. The Coralville Flood-Control Dam on the nearby Iowa River was nearing the final phases of construction, and would ultimately flood the present Lake Macbride with 27 feet of water. Rather than destroy the facilities offered by this established recreational area, the various agencies involved decided to increase the height of the Macbride dam by approximately 29 feet. Surface area of the impounded lake would be expanded to about 940 acres at the new spillway elevation. The Macbride …

Salsola Collina Pall., New To Iowa, William Schapaugh

Proceedings of the Iowa Academy of Science

In October, 1957, a specimen of Salsola was collected in Ames, Story County, Iowa, on the Chicago and Northwestern Railroad, right-of-way embankment at the Sixth Street underpass. This new plant appeared distinct from the various varieties of the well-known Salsola kali L., and search in the Iowa State College herbarium failed to reveal other specimens. Subsequent examination of specimens of Salsola in the herbarium of the State University of Iowa likewise revealed no specimens of this species from Iowa. There seems to be no previous published reports of any species of Salsola other than S. kali from the state of …

The Nature Of Viola Missouriensis Greene, Norman H. Russell

Proceedings of the Iowa Academy of Science

One of the most distinctive of the stemless blue violets of the upper midwest is Viola missouriensis Greene, the Missouri Violet. It is one of the approximately twenty-eight species of the Subsection Boreali-Americanae, Section Nominium, a group of violets somewhat notorious for their propensity for interspecific hybridization. Population studies were initiated in 1956 to define the members of this group more accurately and to determine the effect of hybridization upon their taxonomy and evolution. The Subsection Boreali-Americanae includes the so-called "stemless" (acaulescent), blue-flowered species. Within this group of species, two types of violets can be roughly distinguished: the entire-leaved species …

The Effects Of The Chemical Mutagen, Diepoxybutane, On Clintland Oats, Charles F. Murphy, Fred L. Patterson

Proceedings of the Iowa Academy of Science

The objective of any mutation breeding program is to create desirable genetic diversity. With the spectrum of mutations from ionizing radiations becoming somewhat defined, several workers have investigated the use of chemical mutagens as a method of broadening the range.
