Grain Moisture Problems On The South Coast, J A. Parish, G. H. Jones

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

In most West Australian grain growing districts high temperatures and dry weather at grain maturation are ideal for harvesting and enable delivery of grain with acceptable moisture levels. Grain from W.A. is known in world markets as a good quality dry product which is unlikely to deteriorate in storage. However, growers in coastal areas and particularly those south of Narrogin sometimes have trouble harvesting grain below the receival limit of 12 per cent moisture.

Samphire For Waterlogged Salt Land, C V. Malcolm, G. J. Cooper

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

For non-waterlogged and mildly waterlogged salt land a number of salt-tolerant shrubs may be used for forage production.

Areas which are highly saline and regularly waterlogged are not suited to these shrubs. However, during trials with shrub species, samphires (Arthrocnemum spp.) were found to volunteer and grow well on these sites.

Research into the use of samphires has shown that it is possible to harvest seed and obtain a seed sample suitable for sowing through a drill. Established samphire stands provide useful grazing in many parts of the Western Australian wheatbelt.

Forage Production From Shrubs On Saline Land, C V. Malcolm

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

In the first volume of the Journal of the Department of Agriculture in the year 1900, the results of experiments at Tulare Experiment Station in California on the growing of Australian saltbushes are reported.

Seed was first sent from Australia by Baron von Mueller in June, 1881. Three species of saltbush (A. semibaccata, A. numularia and A. vesicaria) are all reported to have grown well.

Although C. A. Gardner in 1929 suggested the growing of saltbushes for forage, the earliest and clearest recommendations are those of Teakle and Burvill in 1945.

Early research tended to concentrate mainly on the possibility …

Morphological And Physiological Factors Related To Yield Of Alfalfa, A. L. Foutz, Wallace Wilhelm, A. K. Dobrenz

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

Several morphological and physiological factors were measured on clones of alfalfa (Medicago sativa L. ‘Mesa- Sirsa’) which displayed a wide range in SLW, leaflet weight and leaflet area. Apparent photosynthesis, dark respiration and post-illumination burst expressed as mg C0₂ dm^-2hr^-1 were not related to yield. However, when the rate of each factor was expressed on a whole plant basis (rate x leaf area per plant) , significant relationships were found with yield. Correlation coefficients between total apparent photosynthesis, total dark respiration, total post-illumination C0₂ burst and yield were r = .71*, r = .77* …

Potential Insect-Control Applications For Microwaves, Stuart Nelson

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

The idea of using radiofrequency (RF) electric energy for controlling insects is not new. Experiments in the United States to control insects with high-frequency electric fields date back at least 45 years, and reports indicate development of similar interests in Europe during the same period. Many researchers have explored the possibilities since then, and their findings have been reviewed in several publications (Thomas, 1952; Frings, 1952; Peredel'skii, 1956; van den Bruel et al., 1960; Watters, 1962; Nelson, 1966, 1967, 1972, 1973). The purposes in preparing this paper are to summarize these findings in a general way, to discuss some of …

Fisheries Report No 13 - Results Of A Biological Survey Of The Shire Of Kent, Western Australia, N. L. Mckenzie

Fisheries Research Reports

The Department of Fisheries and Fauna is responsible for the conservation of the native fauna in Western Australia. The main approach to this problem has been the creation of reserves for "The Conservation of Flora and Fauna". These reserves, known as "Wildlife Sanctuaries", are controlled by the Western Australian Wild Life Authority - a Statutory Authority serviced by the Department.

The object of the acquisition programme is to develop a reserve system which will include, as far as possible, a full and permanent cross-section of the State's native floral and faunal assemblages and, at the same time, provide for the …

Characteristics Of Deoxyribonucleic Acid Polymerase Isolated From Spores Of Rhizopus Stolonifer , Cheng-Shung Gong, Larry Dunkle, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Deoxyribonucleic acid (DNA)-dependent DNA polymerase was purified several hundredfold from germinated and ungerminated spores of the fungus Rhizopus stolonifer. The partially purified enzymes from both spore stages exhibited identical characteristics; incorporation of [³H] deoxythymidine monophosphate into DNA required Mg²⁺, DNA, a reducing agent, and the simultaneous presence of deoxyguanosine triphosphate, deoxycytidine triphosphate, and deoxyadenosine triphosphate. Heat-denatured and activated DNAs were better templates than were native DNAs. The buoyant density of the radioactive product of the reaction was similar to that of the template DNA. The enzyme is probably composed of a single polypeptide chain with …

Three New Species Of Petrified Dicotyledonous Wood From The Lower Cretaceous Cedar Mountain Formation Of Utah, Gregory F. Thayn

Theses and Dissertations

Two genera and three species of definite fossil angiosperm wood have been identified from the diverse flora of the Lower Cretaceous Cedar Mountain Formation of Utah for the first time. Well preserved fossil dicotyledonous woods have been found in association with the fern Tempskya and conifer woods at two sites, one east of Castle Dale, Utah 1 and one east of Ferron, Utah. Petrified logs were collected from a horizon between ten and thirty feet below the overlying Dakota Sandstone at the Castle Dale site. Dakota Sandstone is missing at the Ferron site, but the wood occurs on the surface …

Effects Of A Nuclear Detonation On Arthropods At The Nevada Test Site, Dorald M. Allred

Brigham Young University Science Bulletin, Biological Series

Fifty-three arthropod species were studied in an area affected by an underground nuclear detonation. These were represented by 10 species of ants, 17 beetles, 5 orthopterans, 4 scorpions, 6 solpugids, and 11 spiders (Table 16). Relative populations were determined prior to the detonation and at three periods after the detonation–(1) one and two months after (August and September 1962), (2) 11 months after (June 1963), and (3) 13 months after (August 1963). One and two months after the detonation, the number of species was reduced from the expected by 48 percent, by 52 percent after 11 months, and by 66 …

Internal Water Potential Of An Engelmann Spruce Stand In Relation To Soil And Atmospheric Factors, Richard L. Meyn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study was to determine the degree of correlation between internal water potential of Engelmann spruce trees and selected environmental factors. The secondary objective of the study was to determine the effect of summer precipitation, both in meadow and forested sites, on the soil drying cycle.

Four study plots (each roughly 154 square meters) under spruce cover and two study plots (100 square meters) in a small meadow were established. At each spruce plot, a thermocouple psychrometer was installed at one meter above the ground on the north side of three selected, mature Engelmann spruce trees. …

Field Measurements Of Photosynthesis And Leaf Growth Rates Of Three Alpine Plant Species, Douglas A. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Leaf photosynthetic measurements using a portable ¹⁴Co₂ field system were carried out and correlative leaf relative growth rates, RGR, were determined at different leaf positions of three alpine plant species throughout the growing season. Initially there was a period of high leaf RGR associated with a period of increasing photosynthetic activity. Following this stage was a long period of no net change in length of the living leaf. During this period, photosynthetic activity generally increased to a maximum level and then decreased steadily. The final ontogenetic stage was a period of negative leaf RGR denoting leaf senescence which …

Autecological Life History Studies Of Two Geraniums, Geranium Richardsonii And Geranium Nervosum, Becky Lee Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two perennial species of wild geranium (Geranium nervosum Rydb. and G. richardsonii Fisch, and Trautv, [Geraniaceae]) which grow throughout the mountainous regions of western North America were studied to determine the factors influencing the life stage development and distribution of these plants. Attempts were also made to provide some information to assist in the taxonomy of this genus.

Geranium richardsonii is found in wet meadows and along streambanks throughout its distribution. Geranium nervosum frequents rocky hillsides and drier meadows throughout its range.

Seeds of G. nervosum had 65%, germination in the stratification pretreatment. Geranium richardsonii seeds required scarification to …
