The Algal Flora (Excluding Class Bacillariophyceae) Of Foster's Pond, Allen County, Kentucky, Linda Garrett

Masters Theses & Specialist Projects

A systematic survey of the algal flora (excluding Class Bacillariophyceae) of Foster's Pond, Allen County, Kentucky, was conducted from January 29, 1970, to March 25, 1971. Physical and chemical data were taken in order to characterize the quality of the water and examine its relationships to floral composition and periodicity insofar as the level of discrimination employed permitted.

A total of 119 taxa representing five divisions were identified. Twenty-five of these were previously unreported for the State of Kentucky.

Members of the Division Chlorophyta, which composed 66.4% of all the identified taxa, dominated the flora throughout the year. Desmid and …

The Effects Of Moist-Heat Treatments And Stratification On Germination Of Prairie Plant Seeds, John E. Stuurwold

Honors Theses

Germination of Silphium terebinthenaceum was enhanced by a post-stratification most-heat treatment at 80°C. Tested seeds of four other perennial herbs common to midwestern prairies (Andropogon scoparius, Sorghastrum nutans, Eryngium yuccifolium, and Solidago rigida) showed little adverse or beneficial effects of the heat treatment. Heat treatments alone had little effect on the seeds; the length of stratification periods necessary to effect maximal germination varied. The significance of these findings is examined in the light of related literature on grassland fire ecology.

Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince

Fisheries Research Reports

The Dampier Archipelago is a group of islands off the north west coast of Australia (20 20! - 20 45'S, 116 Cast . 117°E), first discovered by William Dampier in 1699 and subsequently named after him by the Baudin expedition of 1801. This name has since been applied by some authors to include all islands from Roebourne to North West Cape, including both Barrow Island and the Monte Bello Islands, but it is more correctly applied to those islands within a 30 mile radius of the town of Dampier.

Ir. recent times, three parties have visited the Archipelago and examined …

Following small scale trials in the production and evaluation of Gluclub wheat in 1970 and 1971, farmers have been asked to produce 20,000 tons of this variety for the 1972/73 season.

The background of this attempt to establish a class of soft or biscuit wheat in world markets is described in this article.

Reproductive Wastage In Sheep On Clover Areas, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Western Australia's 67 per cent lambing for 1970 compares poorly with that of other Australian States, and other countries. From the 12.3 million ewes mated in this State's agricultural areas in 1970, only 8.2 million lambs were marked.

This low 77.7 per cent conception rate sparked the present series of reproductive wastage investigations by the Department's Sheep and Wool Branch.

This report describes the first year's results of the project in W.A.'s "clover disease" areas.

Soil And Plant Analysis For Mineral Deficiencies, M D. Carroll

Journal of the Department of Agriculture, Western Australia, Series 4

Soil and plant analysis (testing) has its supporters and its critics. Some of the differences are resolved if the distinction is made between the concept and the practice. Most people would agree with the concept of soil and plant analysis but the practice, or service offered, in any agricultural situation can be subject to valid criticism.

This article defines some of the principles involved and illustrates some of the problems, to provide a better understanding of the usefulness and the limitations of soil and plant analysis as a diagnostic aid in plant and animal nutrition.

Recognizability And Reproducibility Of Airphoto Interpreted Landscape Units, Robert Dean Heil

Electronic Theses and Dissertations

A physiographic terrain analysis study using the principles of airphoto interpretation was made: (1) to determine the internal homogeneity of airphoto interpreted mapping units, (2) to determine the variability in characteristics among different occurrences of the same mapping unit, and (3) to determine if the units differentiated were sufficiently different to warrant discrimination. The study was conducted in Sedgewick County, Colorado. The study area was comprised of four distinctly different land forms [sic]: a major river and its associated floodplain and terraces; a level to nearly level loamy upland plain; a level to sloping sandy upland plain; and steeply sloping, …

Scirpus Validus And S. Acutus: A Question Of Distinctness, Marlyn Miller, E. O. Beal

Journal of the Minnesota Academy of Science

An analysis of 32 populations of bulrushes in the Scirpus validus-acutus complex growing in Itasca State Park and prairie ponds to the west indicates that most of the populations are referable to neither S. validus nor S. acutus but, rather, are intermediate in morphology. Further, the supposedly characteristic features by which the two nomenclatural species have been identified are erratically correlated.

Frost Injury To Cereals In W.A, M W. Perry, A. G. P. Brown

Journal of the Department of Agriculture, Western Australia, Series 4

Late spring frosts commonly reduce yields and affect the quality of grain in wheat crops, especially in the southern, eastern and north-eastern districts. The damage is usually localised on individual farms, but is sometimes widespread.

Barley, and oats to a lesser extent, are also affected. Average losses of wheat in Western Australia have been estimated at 3 to 5 per cent, per year, or about 2 million bushels on current production figures.

A Taxonomic Study Of The Marine Algae Of Netarts Bay, Oregon, Charles Jerome Kunert

Dissertations and Theses

Gathering taxonomic data is fundamental to any biological or ecological research. It was the intent of this paper to increase the storehouse of taxonomic information by studying the marine algae of one section of the Oregon coastline. Netarts Bay was chosen because of its accessibility and generally primitive nature. It is in an area of Oregon largely untouched by phycologists and so offered an opportunity for original research.

Techniques of collecting and preserving specimens were kept as simple as possible, thus allowing a proportionately greater amount of the available time to be spent in the classification of the organisms. The …

Penstemon In Your Garden, R. D. Uhlinger, G. Viehmeyer

Nebraska Agricultural Experiment Station: Historical Circulars

A new race of hardy perennials is beginning to appear in American gardens. These are the penstemons, a genus of plants closely related to the familiar snapdragon, which may become important ornamentals as they be come better known to gardeners. The purpose of this bulletin is to show the possibility of the genus as an ornamental and to suggest species and species hybrids of possible value to Great Plains gardeners; to provide information about propagation and culture; and to encourage gardeners to engage in penstemon breeding as an avocation.

A Pectin Histochemical Study Of The Host Pathogen Relationship Between Pyrenochaeta Terrestris And Allium Cepa, Leroy Richard Cobia

Theses and Dissertations

The involvement of pectin and pectinases in the host pathogen interaction of P. terrestris and Allium cepa were investigated by use of pectin histochemical stains at the electron microscope level. Several different pectin histochemical stains were used, but only two (the hydroxylamine reaction, and the pectin stain developed in this study) gave reliable results. It was observed that by the time the fungus has reached the host cell wall pectinesterase and endoplygalacturonase have fully removed the pectin from the host cell wall. When this has occurred, cellulases are released which continue to degrade the host cell wall. Electron transparent areas …

A Study Of Seed Germination And Establishment Of Seedlings Of Lodgepole Pine In Different Soil Types Under Certain Bog Conditions, Yun-Fan Yuan

Theses and Dissertations

Soil texture, organic matter content, and hydrogen-ion concentration of soil samples were determined to find the correlation between soil characteristics, seed germination and seedling establishment of Pinus contorta. Scarification and stratification were treatments used for determining germination requirements of dormant seeds. Seeds were planted in different soils and experiments were conducted to determine the effects of different light intensities, temperatures, and depths of the water table on apparent photosynthesis rate and seedling establishment. Soil samples, pine cones, and young trees needed for the experiments were collected near Lily Lake, in the Uintah Mountains. The greatest and the fastest germination was …

Soil Surveys In Kentucky, Harry Hudson Bailey, Robert L. Blevins

Agronomy Notes

Soil surveys are a scientific inventory of the soil and land resources of an area. They locate the different kinds of soils and provide information as to their physical and chemical properties. The survey reports also contain tables and charts showing the use of the soils for agriculture, engineering, community development, recreational areas, woodland, and wildlife.

Today there is some type of soil survey activity in every county of Kentucky. The University of Kentucky has cooperative soil survey arrangements with the USDA Soil Conservation Service and the U.S. Forest Service.
