A Comparative Study Of Wood Pulp From The Trunk, Limbs, And Roots Of The Quaking Aspen (Populus Tremuloides), John Vernanth, Raynell Walker, Ann Johnson

Journal of the Minnesota Academy of Science

A three part study was conducted on a single quaking aspen tree (Populus tremuloides): ( l) the strength and other physical properties of fiberboard made from the trunk, roots, and limbs using the cold soda pulping process, (2) the strength properties of paper made from the trunk, root, and limb sections using the Kraft pulping process, and (3) a chemical analysis of the trunk, roots, and limbs. Results of these studies indicate there are significant differences in many of the properties of the three parts of the tree, and that parts of the tree other than the trunk possess useful …

Weed Control In Irrigation Channels, Geoffrey A. Pearce

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

Probably the major task involved in maintaining drainage and irrigation channels is the regular removal of weed growth.

The cost of hand chipping a standard head channel is approximately 10s. per chain.

The use of suitable chemicals could reduce this cost considerably.

"Puccinellia" is a tussocky perennial grass with an outstanding ability to survive salty and waterlogged conditions.

Considerable areas of saltland in Western Australia are suited to its growth.

Seed is now available commercially and in this article the conditions to which the grass is suited are described and establishment and management methods are suggested.

Seed And Pasture Rates For New Dairy Pastures, F E. Ryan

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

THE success or failure of pasture establishment on new land often depends on the interaction of rate of seeding and rate of superphosphate application.

Every year large areas of virgin land are cleared and sown to pasture in the higher rainfall areas, and all-too often the new pasture is not as successful as it should be because too little super is applied, and, in some cases, too little seed.

Thimet For Woolly Aphis Control, G D. Rimes

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

THE woolly aphis Eriosoma lanigerum (Hausm) has been known as a serious insect problem in Western Australia since the early days of apple growing.

It was distributed on nursery stock to most parts of the world in the early days of horticulture.

Wheat Quality Surveys In Western Australia. 2. Variation Between Seasons And Localities In The Production Of High And Low Protein Wheat, J A. Parish

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

Although the protein content of West Australian f.a.q. wheat averages only 9.4 per cent., often substantial amounts of comparatively high protein wheat are contained in this mixture.

However the quantity varies widely from year to year and is obtained from widely scattered areas of the wheatbelt.

Roles Of Hypothalamus And Hypophysis In The Control Of The Estrous Cycle, A. V. Nalbandov

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The interrelation between the hypothalamus and the anterior pituitary gland has been firmly established. It is not the intention of this report to review the literature on this extensive subject. Such reviews are available in "Advances in Neuroendocrinology" (Nalbandov, 2), and since the time of this publication many papers on this subject have appeared in current journals. For the purposes of the present discussion a few fundamental facts will be restated, but the major part of my presentation will deal with my own views of the research areas which should be of special interest to animal scientists concerned with phenomena …

Studies Of The Incorporation Of 5-Fluorouracil Into Tobacco Mosaic Viral Rna By Cell-Free Synthesing Systems Isolated From Infected Tobacco Plants, Helen Lu-Sheng Wang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research on biosynthesis of tobacco mosaic virus (TMV) ribonucleic acid in vitro has been reported by a number of laboratories (8, 16, 17). Bonner et al. postulated that ribonucleic acid could be synthesized from nucleotides by chromatin extracted from nuclei of pea seedlings (5, 14, 22). The evidence from in vitro synthesis of viral RNA suggested that an enzyme, RNA polymerase, links the four nucleotides (ATP, UTP, CTP, GTP) with viral RNA present as a primer and magnesium ions participating as a catalyst (7, 8).

Depletion Of Subsoil Moisture By Apple Trees And Other Woody Species, C. C. Wiggans

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This project began in 1934 and ended in 1955. The work of Kiesselbach, Russel and Anderson indicated that depleted subsoil moisture might be the reason for the loss of many orchards and the injurious effects noted on native woody forest species. Most of the work in apple orchards was done at the University Fruit Farm at Union, Nebraska. Samples were also secured from commercial plantings of apples and other woody species in areas ranging from Rulo, near the Kansas-Nebraska border, to Florence, just north of Omaha, to Lincoln and several points in central Nebraska.

The Pruning Of Fruit Trees : Deciduous Fruit Trees (Apricots), H R. Powell

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

APRICOTS are grown in this State mainly for the fresh fruit market. Varieties commonly grown include Newcastle Early, Royal, Ouillins Early, Blenheim, Moorpark, Trevatt and Tilton.

In some orchards the trees are regularly pruned, but in others they are left unpruned. Unpruned trees are given some renovation pruning from time to time.

Continuation of an illustrated series on pruning fruit trees, by H. R. Powell, B.Sc. (Agric), Chief, Horticulture Division.

Black Spot Of Roses, G C. Macnish

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

ROSES are among the most popular and versatile ornamentals as they may be grown as climbers, bushes or standards.

Black Spot of roses can be prevented by combining good sanitary practices with the regular use of preventative fungicides such as maneb and folpet.

Saffron Thistle, B J. Quinlivan, H. A. Pearce

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

Saffron thistle is a declared primary noxious weed in Western Australia and is especially troublesome in the northern agricultural areas.

Modern Developments In Bulk Handling Of Apples, J C. Rowbotham

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

One of the results of mechanisation replacing physical labour has been the development of bulk handling of many commodities.

Apart from the saving of time, effort and cost, bulk handling of agricultural produce enables quicker harvesting at the right time.

Linseed Growing In The Ord River Valley, D F. Beech

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

Experimental work with linseed at the Kimberley Research Station began in 1952 and has been intensified in the last four years.

Fertiliser requirements and methods of land preparation, sowing, irrigation and weed control have been established.

Suitable varieties have been selected. Farm-scale crops have been grown in the area and, although cotton is very much more remunerative as an establishment crop, it is expected that linseed will ultimately have a place in the Ord irrigation scheme.

Sulfur Fertilizers For Alfalfa Production In Nebraska, R. L. Fox, A. D. Flowerday, F. W. Hosterman, H. F. Rhoades, R. A. Olson

Put Garden Rubbish To Work In A Compost Heap, W Dawson

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

THERE'S a surprising amount of mumbo jumbo written about the simple compost heap. By the time you've waded through all the instructions, you feel as if you ought to have prerequisites of a doctorate in soil chemistry or an unbroken ancestry of at least three generations of professional English gardeners.

Lawns : Their Establishment And Management, H G. Elliott, F. E. Ryan

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

THERE is nothing more pleasing to the eye than a well kept lawn, be it in a home garden or covering a sporting area, and under Western Australian conditions there is no reason why a good lawn or turf cannot be developed and maintained—always provided that there is enough water and proper care and attention.

Mites On Kangaroo Rats At The Nevada Test Site, Morris A. Goates

Brigham Young University Science Bulletin, Biological Series

A systematic study of parasitic mites on kangaroo rats of two species at the Nevada Test Site was conducted from August 1959 to December 1961. The intent was to determine the kinds, numbers, seasonal occurrences and ecological relationships of mites in nuclear disturbed and contiguous undisturbed areas. A total of 1,256 rats from nine plant communities was examined.

The 6,208 mites collected represented 16 species including four undescribed. Fourteen were found on both kinds of rats. Considerably more rats were infested with chiggers than with mesostigmatids. Each species of mite occurred alone on its host at least 20% of the …

The Development Of Irrigation In Nebraska, 1854–1910: A Descriptive Survey, Martin Evald Carlson

Department of History: Dissertations, Theses, and Student Research

Preface (excerpted)

The primary purpose of this study is tto trace the development of irrigation in Nebraska from the organization of the state as a territory in 1854 through the rest of the nineteenth century. This period covers the first four stages through which irrigation progressed: individualistic, corporate, district, and state. A brief discussion of the North Platte Project is included, however, in order to carry the story into the fifth and final stage--the development of irrigation with Federal aid, as provided for in the Reclamation Act of 1902.

The emphasis of this work is on the irrigation movement and …

Influence Of Sodium And Calcium Chlorides On Respiration Of Tissues From Several Plant Species, Hossein Lessani

The growth of plants on saline and alkaline soils has occupied the attention of agriculturists and scientists for many years. Saline soils are found in many parts of the world and present real problems to crop production.

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 …

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).
