Grain and other field crops published reports

Lentil is one of the grain legumes with potential for inclusion into Australian farming systems on fine textured, neutral to alkaline soils. It is an important protein source for the large populations of the Indian sub-continent and elsewhere, and the export market potential is excellent. Old Canadian varieties grown on a small scale in Victoria (Laird and Callisto) are poorly adapted to short season WA environments, A number of varieties have recently been selected from ICARDA material and released in Victoria and SA (Digger, Cobber, Matilda and Aldinga), and these have adequate adaptation to commence a lentil industry in WA. …

Fast Tracking Barley Varieties Using Anther Culture, Sue Broughton, Penny Priest Jan 1994

Fast Tracking Barley Varieties Using Anther Culture, Sue Broughton, Penny Priest

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

Breeding new varieties of barley or other cereal crops usually takes between 12 and 15 years. five years of that time may be needed to stabalise the new varieties so that they breed trueto type, but anther culture can reduce this delay to only eight months. This technology will allow the Department of Agriculture's barley breeding programme to respond more rapidly to changes in goals set by industry and to meet market demands.

New Yellow Serradella Varieties For Low Rainfall Pastures, Clinton Revell Jan 1992

New Yellow Serradella Varieties For Low Rainfall Pastures, Clinton Revell

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

Large areas of acidic, sandy soils in Western Australia's low and medium rainfall, wheatsheep areas are suited to the pasture legume, yellow serradella.

In the past, a lack of varieties with suitable maturity has limited the use of this species.

New varieties developed in Western Australia and significantly earlier in maturity than traditional types can now extend the use of yellow serradella into these regions.


Local Polyploid Variation In The Native Prairie Grass Andropogon Gerardii, Kathleen H. Keeler Jan 1992

Local Polyploid Variation In The Native Prairie Grass Andropogon Gerardii, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

The microscale distribution of polyploid variants of the dominant grass big bluestem (Andropogon gerardii) in virgin tallgrass prairie was mapped using flow cytometry. The correlation between DNA content and polyploidy allows the use of flow cytometry for nondestructive determination of polyploidy in intact plants. At Konza Prairie, local plots contained from 0 to 100% hexaploid cytotypes but most showed fine-scale mixing of the polyploid variants. The relationship of cytotype frequency to moisture availability or burning history was nonsignificant

Origin And Evolution Of Defective Interfering Rnas Of Tomato Bushy Stunt Virus, David A. Knorr, Thomas Jack Morris Jan 1991

Origin And Evolution Of Defective Interfering Rnas Of Tomato Bushy Stunt Virus, David A. Knorr, Thomas Jack Morris

School of Biological Sciences: Faculty Publications

Viruses with defective genomes have been identified in association with virtually every major family of viruses and have been widely utilized as tools for investigating virus functions in animal cell culture systems (Perrault, 1981). It is generally thought that defective interfering viruses (DIs) arise through deletion, rearrangement, or recombination of a competent viral genome. DIs tack the ability for independent existence relying on their parental helper viruses to supply factors required for replication, maturation, and/or encapsidation (Huang and Baltimore, 1977). The interference attributed to DIs is thought to result from competition with the helper virus for factors required in trans …


Sexual Dimorphism And Intersexual Differences In Resource Allocations Of A Dioecious Shrub, Lindera Melissifolia (Walt.) Blume, Dennis J. Richardson, Robert D. Wright, Shannon Walker Jan 1990

Sexual Dimorphism And Intersexual Differences In Resource Allocations Of A Dioecious Shrub, Lindera Melissifolia (Walt.) Blume, Dennis J. Richardson, Robert D. Wright, Shannon Walker

Journal of the Arkansas Academy of Science

Morphometric data were gathered to make intersexual comparisons on the morphology and reproductive resource allocation patterns of the rare, dioecious shrub, Lindera melissifolia. Females produced significantly fewer flowers and leaves than did males. No other significant differences could be detected in morphology. Female "clones" exhibit low area coverage and low stem density, which suggests higher costs of reproduction. If this is the case, the deficits produced in resource allocations directed toward sexual reproduction seem to result in increased mortality and/or reduced vegetative reproduction.

Jamaican Blue-Green Algae Collections Of J.C. Strickland, W. John Hayden

Biology Faculty Publications

Professor John C. Strickland (1915-1980) devoted much of his life to teaching biology, botany, and phycology at the University of Richmond. Throughout his academic career he maintained a keen interest in the Myxophyceae, or blue-green algae, studying their culture, cytology, and taxonomy (Drouet & Strickland, 1942; Strickland, 1940, 1946). Most of his collections of these and other algae were made in Virginia and are housed in the herbarium maintained by the Department of Biology, University of Richmond. However, he also made four trips to Jamaica in the years 1966-1971 before his health deteriorated to the extent that field work, and …

Bulletin 3990 - The Narrow-Leafed Lupin In Western Australia, J. S. Gladstones Apr 1977

Bulletin 3990 - The Narrow-Leafed Lupin In Western Australia, J. S. Gladstones

Bulletins - 3000 - 3999

Lupins are new as a commercial crop, but may be very old as a food plant. Types of the Mediterranean white lupin (Lupinus albus L.) have been part-developed and used as a subsistence crop for 3 000 years or more. Likewise the pearl lupin (L. mutabilis Sweet) has been grown for many centuries in the Andean Highlands of South America. In both cases the seeds are boiled and steeped in water for several days to rid them of their bitter, somewhat toxic alkaloids. They are then used directly as a valued protein source in human diets.

An Investigation Of The Nucleotide Cyclic 3'5' Adenosine Monophosphate In Young Hypocotyls Of Pisum Sativum L., Gary Marsh Hilton

Biological Sciences Theses & Dissertations

Concentrations of cAMP increased with time in pea hypocotyls assayed at 24 hour intervals over a period of four days. The highest concentration was 20.1 pmoles/mg protein which occurred in 96 hour hypocotyl tips. Ninety-six hour root bodies (dissected region between tip and embryo) achieved a concentration of 8.6 pmoles/mg. Concentrations of cAMP in embryos remained constant around one pmole/mg for three days and values doubled on the fourth day.

Hypocotyls, after germination for 72 hours, were dissected and incubated for various lengths of time in water and 3xl0-8M IAA. Tips incubated for two hours showed a tenfold …


The Mediterranean White Lupin, John Sylvester Gladstones Jan 1976

The Mediterranean White Lupin, John Sylvester Gladstones

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

"If you want to bring in a good lupin harvest, thrash your wife soundly before you go out sowing in the field". Old Syrian Proverb.

Lupin breeder Dr. John Gladstones does not beat his wife as recommended in the Syrian proverb above. Nor is he known to use ground up lupin seeds for the diverse cosmetic and medicinal purposes recommended in ancient Roman and other texts on lupins.

But his modern work on lupin breeding and development has undoubtedly been influenced by his detailed study of such writings.

In this article he discusses the history of the Mediterranean white lupin …

Subterranean Clover In W.A. 2. Characteristics Required For Agronomic Success, C M. Francis, B. J. Quinlivan, N. J. Halse, D. A. Nicholas

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

Development of subterranean clover varieties is a rapidly changing scene, particularly in terms of farmer acceptance, disease and persistency problems. This is only to be expected, because this is an agricultural plant of only some 50 to 70 years standing, whereas many other pasture plants have been in common use for thousands of years.


The Art And Science Of Plant Breeding, John Sylvester Gladstones Jan 1973

The Art And Science Of Plant Breeding, John Sylvester Gladstones

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

The first part of this article described the evolution of crop varieties and their improvement by simple selection. This part discusses cross-breeding and the other techniques which underly most modern plant breeding programmes.

The purpose cf crossing is to generate new combinations of varietal characteristics. It does not create anything basically new. All the genetic "ingredients" of a new variety must be present in one or other of the parents.

Pasture Seed Production In Western Australia, B J. Quinlivan Jan 1969

Pasture Seed Production In Western Australia, B J. Quinlivan

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

Pasture seed production in Western Australia is an industry with a somewhat turbulent past. Booms and slumps have been the rule rather than the exception.

However, during the past few years there has been some degree of "stability"—if not in price, at least in terms of total production.


The History And Characteristics Of Troodos And Olympus Rose Clover, E T. Bailey, N. B. Gayfer Jan 1968

The History And Characteristics Of Troodos And Olympus Rose Clover, E T. Bailey, N. B. Gayfer

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

ROSE CLOVER is being produced and used in increasing quantities in south-western Australia. The first line named was designated Kondinin and five lines have now been given cultivar (variety) names.

One of the first samples of rose clover, C.P.I. 13949, introduced into Western Australia proved to be a mixture of two very similar types, differing visibly only in leaf markings.

The mixed sample was named Troodos,* and the selection from it, Olympus.

This paper describes the origin of the two varieties, their history and characteristics.
