Range Feeding Of Cotton By-Products In The Kimberleys, John Hubert Auty

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

Commercial cotton production has started in the Ord River area and by-products of the industry will soon be available for stock feeding in the surrounding pastoral areas.

Cotton seed and cotton seed meal will cause digestive upsets if fed in any quantity to horses, poultry or pigs.

Ruminants have no trouble in handling the material and the Kununurra ginnery could supply a useful protein supplement for Kimberley cattle.

Hyperparasitism, Michael G. Boosalis

Department of Plant Pathology: Faculty Publications

Much of the research on hyperparasitism has been of a descriptive nature, based primarily on studies with dual cultures in synthetic media. The main contributions from these investigations concern the host range of the parasite, the mode of penetration and infection, and the morphological changes of the host and the parasite resulting from parasitism.

More recent studies on hyperparasitism emphasize the effect of environmental factors, especially nutrition, on the susceptibility of the host. Research on the physiology of hyperparasitism has been limited. Nevertheless, this important aspect of the problem should continue to receive increased attention as hyperparasitism is extremely amenable …

Leaf Ribonuclease Activity As Related To Virus Infection, And Ribonucleic Acid Concentration, Andrew Chien-Yau Hsu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ribonucleic acid (RNA) appears to be the entity responsible for infectivity and genetic continuity in certain plant, animal and bacterial viruses. RNA also plays an important role in protein synthesis. The enzymes which are involved in RNA synthesis and degradation have received much attention. Among these enzymes ribonuclease (RNase) has been most thoroughly studied Rnase is widely distributed and has been isolated from many sources such as snake venom, bacteria, the pancreas, and many plant and animal tissues. Most studies with RNase have been concerned with its role in the hydrolysis of RNA in vitro. Therefore, it has generally been …

Biosynthesis Of Infectious Cucumber Mosaic Virus Ribonucleic Acid In A Cell-Free Medium, Men Hui Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mechanism of biosynthesis of the nucleic acids, RNA, remained obscure until 1955 when the announcement was made (14) that an enzyme isolated from bacterial sources catalyzes the synthesis of ribopolynucleotides from nucleoside-5'-diphosphates. It has been shown that the biosynthesis of polynucleotides occurs through the stepwise polymerization of nucleoside-5'-diphosphates or triphosphates. A great deal of research over the past few years has indicated that isolated nuclei from both animal (1) and plant (19) sources are able to synthesize ribonucleic acids in vitro (18).

The Biochemical Differences Associated With Iron Chlorosis In Higher Plants, Daniel Ming-Yi Teng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chlorosis, which is associated with a reduction in the chlorophyll content of leaves, is a major problem in the growing of deciduous fruit trees and some field crops on calcareous soil. Under various soil conditions more than one factor may be involved in the development of chlorosis in plants. A deficiency of magnesium, manganese, zinc or iron, and virus infections can induce chlorosis. It is also induced by the presence of high concentrations of phosphate, bicarbonate, manganese, copper, zinc, or numerous other factors.

A Nutritional Survey Of Sweet Cherry Orchards In Utah, M. Dale Christensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The sweet cherry crop has always been the number one fruit crop in Utah until the last three or four years when it shifted to second place due to severe spring frosts. However, the outlook for its continued success is still very good. Even though there are drawbacks such as virus infestations, spring frosts, nutritional disorders, cracking, doubling, and bird injury, new plantings are being made each year in each of the important fruit producing counties. Utah is also important in the national production of sweet cherries and is presently sixth in the nation.

A nutritional survey of sweet cheries …

The Respiratory Chain Involved In Oxidative Phosphorylation On Higher Plants In Relation To Carbon Dioxide-Bicarbonate Inhibition, Wan-Jean Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Increased concentrations of CO₂ with the accompanying high bicarbonate level in the culture medium have been reported to have a depressing effect in certain plant species on growth (34), respiration (23, 33), oxidative phosphorylation (9), mineral nutrient absorption (17), certain enzymatic reactions (4, 22, 27), accumulation of organic and amino acids (11), and protein synthesis (16). Since accumulation of organic acids occurs in lime-induced chlorotic tissue together with a depression in the respiration of plant tissue, an effect on the energy transfer mechanism of such plants is suspected. Inhibition of electron transfer from the substrate level could result in …

Infrared Spectroscopy As Applied To The Study Of Biochemical Changes Induced By Tobacco Mosaic Virus In Leaf Cells, Banavara Krishnappa Chandrasekhar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The biochemical reactions occurring during the early stages in the infection cycle of a plant virus are still unknown. Many studies involving bacteriophage and animal viruses that have been made in recent years have provided evidence of the nature of virus infection, but these have not been of much value in understanding the nature of plant viruses. Infrared spectroscopy applied to the study of viral infection processes by Chochran and his co-workers (1960, 1962) have given some clues about the nature of biochemical changes taking place in the leaf tissues as a result of infection with cucumber mosaic virus and …

Iron Deficiency Of Oats In The Lower South West, Edgar Noel Fitzpatrick, R. Sprivulis

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

Oats grown on the acid peaty sands of the West and South Coastal areas of Western Australia develop iron deficiency.

This deficiency can be cured by spraying with iron sulphate. A 2 to 4 per cent, solution can be applied through a low volume spray without damage to the plants. The spray should be repeated when deficiency symptoms reappear.

Growing oats on these soils is not recommended.

This report marks the completion of the second year of research at this farm. Experimental work was continued in the areas of fertility and cultural practices, plant disease control, crop management, and crop variety testing. Investigations were expanded into corn plant populations, potassium deficiency, plant breeding and genetic studies on corn, grasses, legumes, sorghum and soybeans. Livestock research was initiated in the spring of 1962 when 106 feeder pigs were placed in three temporary buildings constructed for this purpose. Results of this trial are summarized in this report. Ninety(90) fall pigs have been started as a continuation of this experiment.

Differential Salt Tolerance Of Hordeum Jubatum, Agropyron Trachycaulum, And Their Natural Hybrid Elymus Macounii, Marian Lucy Hanna

Theses and Dissertations

Because plants show a wide range of variation in growth in the presence of excessive concentrations of soluble salts in the soil, this study was undertaken to determine the effects of various concentrations of NaCL and Na2SO4 on the growth and development of Hordeum jubatum, Agropyron trachycaulum, and the natural hybrid of these two plants, Elymus macounii.

Biochemical Studies On The Effect Of Fluoride On Higher Plants, Shang-Fa Yang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluoride occurs naturally in plants, but its presence has attracted attention primarily in certain industrial areas where concentrations are elevated above normal by accumulation from the atmosphere. Certain plant species have been observed to be injured as a result of accumulation of excessive fluoride from the atmosphere. The general symptoms of fluoride injury are necrotic lesions and burning which appear first in the leaf tips and margins.

A Genetic Investigation Of A Yellow Plant Color Characteristic In Winter Wheat, John Oscar Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective in wheat hybridization primarily is to obtain new varieties which are of a greater agronomic value than existing varieties. Frequently, however, crosses which obviously will not produce superior commercial types are made and studied in order to obtain genetic information which may be useful to the breeder. This latter phase of breeding, i.e., the accumulation of genetic information, provides the basis for this study.
