Comparative Anatomy And Systematics Of Picrodendron, Genus Incertae Sedis, W. John Hayden

Biology Faculty Publications

This study of the vegetative anatomy of Picrodendron and some of its putative relatives has been undertaken in order better to understand its natural relationships. Despite the number of anatomical studies in the literature (Jadin, 1901; Solereder, 1908; Boas, 1913; Webber, 1936; Heimsch, 1942; Record & Hess, 1943; Metcalfe & Chalk, 1950), our information on the anatomy of Picrodendron is still incomplete· for example, nodal and petiolar anatomy has apparently never been described. Furthermore, with the exception of Record and Hess (1943), who discussed Picrodendron in a family by itself, other anatomists have compared Picrodendron only with members of Simaroubaceae, …

A Description Of Vascular Plant Species From An Area In The Central Sierra Nevada Foothills Of California, Thomas Carter Hensel

University of the Pacific Theses and Dissertations

Much work has been done on the remarkably diverse flora of California but few specific studies of the foothills of the Central Sierra Nevada Range have been undertaken. One such area is Calaveras County, a region rich in the early history of California.

The site chosen for this study ranges from approximately 2350 to 2700 feet in elevation. It is well defined by survey and accessible at all times of the year. The primary objective of the study was to determine what vascular plant species occur naturally in the area. This was accomplished by extensive collections made from April 1970 …

Why Botanical Names Are Necessary, Robert Dunlop Royce

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

BOTANISTS engaged in naming plants are ofen asked "Why can't you speak English?"

The answer becomes quite clear as the inquirers learn more and more about plants and find people calling the same plant by quite different names.

Use Of The Antibiotics, Streptomycin And Terramycin, As Growth Stimulants For Orchid Seedlings, Margaret W. O'Neill

Biology ETDs

Antibiotics first came to the public's attention in 1945, when penicillin and streptomycin were released by the United States government to fight human diseases. Later, other antibiotics were released and experimental work was done on control of plant and animal diseases. By 1948 plant pathologists found that certain plant diseases such as walnut blight, tomato and pepper bacterial spot, soft rot, cucumber, downy mildew, chrysanthemum bacterial wilt, and lilac bacterial blight could be controlled by antibiotics.

Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Approximately three and one-third million acres of native prairie are harvested annually in Nebraska for hay. In the four-year period 1948-1951, the State ranked first in wild hay production with an average yield of more than two and one-quarter million tons per year. This crop is an important natural resource in Nebraska's livestock industry. Studies were initiated in 1945 to determine the effects of time of cutting on the yield and feeding value of prairie hay in southeastern Nebraska. The studies were continued through the summer of 1952 to determine the effects of different cutting treatments on the vigor and …

Cytogenetic Studies In The Genus Cymbidium, Donald E. Wimber

CGU Theses & Dissertations

The orchids known today make up one of the largest Angiospermous families in the world. Recent estimates place the number of genera at about 450 which estimates between 10,000 and 15,000 species (some authorities go as high as 20,000). They are without doubt one of the most highly specialized groups of green plants. Botanically the flowers are of more than passing interest for they deviate so distinctly from the norm of the Monocots. They are the possessors of a number of unique structures that are found in no other family of flowering plants.

An Etiological And Host Range Study Of Celery Mosaic In Utah, Dennis H. Hall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Celery mosaic is a virus disease of major economic importance in Utah. In years of severe epiphytotics, it has been a limiting factor in celery production. In 1947 losses due to this disease were estimated to exceed 8 per cent of the total crop. This estimate does not include losses resulting from reduction in grade or from plants discarded in the packing sheds. The celery acreage in Utah dropped from a high of 950 acres in 1946 to 750 acres in 1947 and dropped again in 1948 to 420 acres. Leaders in the industry attributed this reduction in acreage, in …

Drug Plants Of California, Frederick Louis Beauchamp

University of the Pacific Theses and Dissertations

Many books and articles have been written covering the flora of California. Few, however, have dealt specifically with those plants yielding drug principles used in the materia medica of the medical and pharmacy professions. Over one thousand different species of native and introduced drug plants are growing in the state. Many of these, it is true, have fallen into disuse, either because of lack of medicinal value, or substitutes have been found in the laboratories of the chemist.

The development of the drug farming industry will not only give employment to the state’s increasing population, but will enable our nation …

Common Native Grasses Of Nebraska, A. L. Frolik, F. D. Keim

Nebraska Agricultural Experiment Station: Historical Circulars

Twenty-four native grasses that are the most important and most generally distributed in Nebraska are described and illustrated in this circular. Information concerning their distribution and economic value is given. Anyone interested in learning to identify the common native grasses should be able to do so by comparing plant specimens with the illustrations and descriptions herein presented. The work of identifying grasses may seem technical and limited only to botanists or those with similar training. Nearly anyone, however, can learn to identify many of the native grasses if willing to spend a little time and effort.

Rocky Mountain Flowers, Frederic E. Clements, Edith Schwartz Clements

School of Biological Sciences: Faculty Publications

AN ILLUSTRATED GUIDE FOR PLANT-LOVERS AND PLANT-USERS WITH TWENTY-FIVE PLATES IN COLOR AND TWENTY-TWO PLATES IN BLACK AND WHITE

The present book is an endeavor to present the materials of the Rocky Mountain flora in preliminary form from the standpoint of the experimental ecologist. The latter is concerned primarily with the relationships of "species" and their subdivisions as an organic expression or measure of habitat differences, and of the competitive relations of the various formations. Whatever the taxonomic value of the numerous segregates of the last decade or two, the fact that the binomial form conceals the relationship to the …

On The Movements Of Petals, Esther Pearl Hensel

University Studies (University of Nebraska) (1888–1984)

The following paper has to do with an investigation of the physical causes· which bring about opening and closing movements, periodic or otherwise, of certain flowers. With that end in view, seven different species of flowering plants have been experimented upon directly, a much larger number being simply observed with respect to the nature, time, etc., of their anthotropic movements. Movement consists in the corolla taking upon itself either the open or closed position for certain periods of the day or night; for example, the morning glory (Ipomoea purpurea) opens early in the morning (from 4:00 to 5 …
