Genetic Manipulation Of Tall Fescue, Jeffrey F. Pedersen, D. A. Sleper
Genetic Manipulation Of Tall Fescue, Jeffrey F. Pedersen, D. A. Sleper
Department of Agronomy and Horticulture: Faculty Publications
Genetic manipulation of tall fescue (Festuca arnndinacea Schreb.) has not been altered by the discovery of the Acremonium coenophialum (Morgan-Jones and Gams) / grass interaction. However, tall fescue breeding programs have been affected greatly. The basic methods for genetically manipulating the grass have remained static. Tall fescue is an obligate out-crossing species, and most improvements are, therefore, captured in the form of an improved population developed through some form of mass or recurrent selection. What has changed is the breeder's ability to recognize genetic differences in the grass because of the confounding effect of A. coenophialum on plant phenotype. It …
Comparison Of Sorghum And Indiangrass Chloroplast Genomes Using Rflps, Jeffrey F. Pedersen, R. D. Lee, D. J. Lee, K. P. Vogel
Comparison Of Sorghum And Indiangrass Chloroplast Genomes Using Rflps, Jeffrey F. Pedersen, R. D. Lee, D. J. Lee, K. P. Vogel
Department of Agronomy and Horticulture: Faculty Publications
Sorghum (Sorghum bicolor (L.) Moench) and indiangrass (Sorghastrum nutans (L.) Nash) appear closely related based on morphological and chemotaxonomic characters. Each species could potentially provide desirable traits to the other. However, traditional breeding techniques have been unsuccessful in hybridizing these two species. The objective of this study was to determine the relatedness of sorghum and indiangrass chloroplast DNA using RFLPs. Eleven sorghum lines in several cytoplasms, two indiangrass popu1ations, and a corn line were studied using 60 proberestriction enzyme combinations. Principal component analysis of the results showed sorghum to be as closely related to corn as to indiangrass, with no …

Visions For Agriculture, Department Of Agriculture, Western Australia
Agriculture reports
This workshop grew out of a conversation between Maurice Barnes, a Trayning farmer and member of the Research Advisory Committee of the Dryland Research Institute, and Steve Porritt, the officer in charge of the Dryland Research Institute at Merredin. Maurice was interested in the idea of posing the question 'What would agriculture be like if we had known as much about this landscape in 1829 as we know now?', to a group of farmers and others interested in the central wheatbelt and its future. Maurice saw this question as a first step toward achieving some shared vision for the future …

Distribution And Ecological Significance Of On-Farm Bushland Remnants In The Southern Wheatbelt Region Of Western Australia, F Mollemans, G Beeston
Soil conservation survey collection
The Southern Wheatbelt Region Remnant Vegetation Survey was funded by the Save the Bush program, and aimed at surveying pieces of on-farm remnant vegetation in the "Great Southern" of Western Australia. At the outset a total of 13 shires were selected for survey, namely: Broomehill, Corrigin, Dumbleyung, Katanning, Kent, Kondinin, Kulin, Lake Grace, Narrogin, Tambellup, Wagin, Wickepin, Woodanilling. However, time constraints (available funding indicated a time frame of 40 weeks for the project to be completed) meant that subsequently Kent and Lake Grace shires (two of the largest) had to be dropped from the survey to allow for proper completion …

Plan For Neridup Creek Catchment Neridup Soil Conservation Group, Martyn G. Keen
Plan For Neridup Creek Catchment Neridup Soil Conservation Group, Martyn G. Keen
Soil conservation survey collection
This report was initiated at the request of the Neridup Soil Conservation Group as an aid to overcoming the degradation problems of the catchment known as the Neridup Creek Catchment.Work was commenced on collecting data about the catchment in May 1990 and has continued on a part-time basis as workload has permitted. This report outlines the physical details of the catchment, predicts runoff peak flows and contains recommendations as a framework for stable land use within the catchment.Attached to this report are: a set of maps of physical details, a set of plans related to individual degradation problems requiring solutions …

Navail Spreadsheet, S J. Burgess
Navail Spreadsheet, S J. Burgess
Agriculture reports
A computer program called NPDECIDE has been developed by the Western Australian Department of Agriculture to assist with decisions relating to the use of phosphorus fertiliser on cereal crops. NPDECIDE functions by estimating the response of the crop to combinations of nitrogen and phosphorus fertilisers, and by indicating the likely profit from the use of these materials. In order to carry out this task, NPDECIDE must be able to calculate the availability to the growing plants of nitrogen from the fertilisers and from organic material in the soil.
Jasmonate, Genes, And Fragrant Signals, Paul E. Staswick
Jasmonate, Genes, And Fragrant Signals, Paul E. Staswick
Department of Agronomy and Horticulture: Faculty Publications
Although first recognized for its growth-inhibiting activity about 20 years ago, JA2 and its fragrant methyl ester MeJA (referred to here collectively as jasmonate) are receiving renewed interest as potentially important signaling molecules in plants. This is because jasmonate markedly increases the expression of specific plant genes, some of which are wound responsive. Similarities with fatty acid-derived stress signaling molecules in animals (1) make jasmonate of general biological interest.

Review Of The Wild Oat Inflorescence And Seed: Anatomy, Development And Morphology, M. V. S. Raju, David M. Sutherland
Review Of The Wild Oat Inflorescence And Seed: Anatomy, Development And Morphology, M. V. S. Raju, David M. Sutherland
Biology Faculty Publications
This slim volume describes a detailed study of the reproductive parts of Avena fatua, the wild oat plant-a common weed in the northern plains and the probable ancestor of the cultivated oat. The book integrates the author's own work with information from available literature and includes lengthy technical descriptions of the structure and the growth of the inflorescence, the floret, the ovule, the pollen grain, the embryo, the seed, and the young seedling. Throughout the work, the author relates the wild oat's structure and development to other grasses, other monocotyledons, and other seed plants, offering evolutionary interpretations of many of …
