Summer Soil And Air Temperatures In Four Plant Communities, Paul W. Conrad
Summer Soil And Air Temperatures In Four Plant Communities, Paul W. Conrad
Theses and Dissertations
Temperature, one of the most influential factors controlling the growth and distribution of plants, was measured during a three month summer period within several stands of vegetation. The stands represented four distinct plant communities: sagebrush-grass, mountain brush, aspen, and conifer. Measurements were obtained by a sucrose inversion method which gave exponential average or effective mean temperature (eT) values. Registerants, small glass vials filled with a sucrose-buffer solution, were placed in the air 10 decimeters above the ground level and in the soil 1, 5, and 10 decimeters below the ground level. The sites were carefully described with respect to plant …
Mammal Populations And Their Effects On Red Elderberry In The Mud Creek Sheep Allotment, Stawberry Valley, Utah, Howard Duane Smith
Mammal Populations And Their Effects On Red Elderberry In The Mud Creek Sheep Allotment, Stawberry Valley, Utah, Howard Duane Smith
Theses and Dissertations
The purpose of this study has been to determine : (1) the mammalian species present in the Mud Creek area; (2) the approximate population density of each trappable species; (3) the species responsible for the damage; (4) the stem density and frequency of Smbucus racemosa; and (5) the approximate extent of damage to the red elderberry stems.
A Microscopic Study Of An Early Pennsylvanian Flora From The Manning Canyon Shale, Utah, Max W. Blaylock
A Microscopic Study Of An Early Pennsylvanian Flora From The Manning Canyon Shale, Utah, Max W. Blaylock
Theses and Dissertations
The Manning Canyon Shale on the eastern slope of Lake Mountain in Utah County, Utah contains an Early Pennsylvanian flora within its upper shales. Many of these fossils appear to be new species. A microscopic study of the tissue remains can be of value in the further classification of these fossils. Selected fossils were macerated in hydrofluoric acid, and the residues were examined microscopically for tissue remains. Objects identified as fossil tissue remains were found in twenty five of the forty-eight specimens examined. Fibers, fiber tracheids, tracheids, and spores were isolated from fossils identified as Calamites. The spores were possibly …
A Phytosociological Study Of Coprophilous Ascomycete And Basidiomycete Communities From Santaquin Canyon, Utah, A. Clyde Blauer
A Phytosociological Study Of Coprophilous Ascomycete And Basidiomycete Communities From Santaquin Canyon, Utah, A. Clyde Blauer
Theses and Dissertations
Numerous reports have been published on the taxonomy and distribution of the coprophilous Ascomycetes and Basidiomycetes. No known quantitative work has been done, however, on the succession and structure of the communities formed by these higher fungi. This research was undertaken to study those two phases of the ascomycete and basidiomycete communities which grow and fruit on cow dung collected from Santaquin Canyon, Utah.
Revision Of Gilia (Polemoniaceae) Section Gilmania, M. Eileen Matthews
Revision Of Gilia (Polemoniaceae) Section Gilmania, M. Eileen Matthews
Theses and Dissertations
The results of this study show that section Gilmania (genus Gilia) consists of only two species G. latifolia and G. ripleyi, which are well separated from the rest of the members of genus Gilia by their simple, aristately toothed, obovate to orbicular leaf blades, many, small, brilliant rose, salverform corollas, basally inserted, stout-filamented stamens, and 30 to 100 small, reddish-brown, oval seeds per locule.
Effect Of Fluoride On Respiratory Enzymes In Soybean Leaves, Arthur Chiu-Eng Lee
Effect Of Fluoride On Respiratory Enzymes In Soybean Leaves, Arthur Chiu-Eng Lee
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
There are many reports relating the effects of fluorides on plant respiration. Fluoride has been regarded as an inhibitor of respiration. Warburg et al. (1942) demonstrated that fluoride inhibited enolase activity, therefore, decreased the respiration rate of yeast. Miller (1958), found a similar inhibition of enolase from pea seed. Bonner (1948), Bonner and Wildman (1946), and Laties (1949) reported that the fluoride ion in culture solutions reduced the respiration rate in Avena Coleoptile, spinach leaves and barley roots. Since the inhibition was reversed by the addition of pyruvate, they concluded that the inhibition of respiration was due to the inactivation …

A Survey Of The State Of Utah For Areas Infested With The Stem Nematode Of Alfalfa, Dwayne R. Buxton
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Plant nematodes belong to a large group of invertebrates known as round worms, They derive their name from the Greek word "nema," meaning thread. In literature some authors refer to nematodes as nemas. In England and many parts of the United States, plant-parasitic nematodes are called eelworms.
While some damage to plants results from mechanical injury, salivary secretions injected by the nematode into the plant are usually the major cause of damage. Experiments conducted in the first part of the present century have demonstrated large differences in plant growth in soil infested with nematodes and soil freed of nematodes by …
