Coping With Brown Spot And Root Rots Of Lupins, Mark Sweetingham

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

There is increasing concern that brown spot and root diseases may limit the long term viability of lupin cultivation in close rotations in the agricultural areas of Western Australia. Research has found several useful strategies to reduce the impact of brown spot and Pleiochaeta root rot so that losses can be kept to a minimum. Rhizoctonia has proved more difficult to combat. Although less widespread than Pleiochaeta, it has caused severe losses and appears to be increasing in incidence, particularly in the northern wheatbelt. Research has vastly expanded our knowledge of the strains of Rhizoctonia present in our soils and …

Dominance Relationships Of Cycloheximide-Resistant Mutants Of Schizophyllum Commune Fr., Marjorie Meier Eerdmans, Sally A. Amundson, Todd A. Reinhart, Keith K. Klein

Journal of the Minnesota Academy of Science

We have isolated several mutants of Schizophyllum commune Fr. able to grow on media containing cycloheximide in concentrations up to 30 mg/L. Genetic analyses of the resistant phenotypes show them to be due to the action of a single gene located on the first linkage group between the A-mating type factor and a gene for an adenine requirement (ade-ll). We have analyzed the growth and development of dikaryons made homoallelic for either the resistant or sensitive alleles as well as the heteroallelic dikaryon. These dikaryons showed different abilities to fruit when placed on media containing various concentrations of cycloheximide. Homoallelic …

Genotypic And Chemical Influences On Fruit Growth Of Tomato, Henry R. Owen, Louis H. Aung

Faculty Research & Creative Activity

A relationship between ovary size at anthesis and final fruit diameter of 12 tomato (Lycopersicon esculentum Mill.) cultivars with a range of fruit sizes, shapes, and maturation rates was determined. ‘Fireball’, ‘Michigan/Ohio Hybrid’, and ‘New Yorker’ produced nonfasciated, spherical fruits of intermediate maturation rate and showed a significantly higher correlation between ovary diameter at anthesis and final fruit diameter than ‘Small Fry’, ‘Roma VF’, ‘Early Cascade’, ‘Campbell 1327’, or ‘Ponderosa’. A linear regression of final fruit diameter at maturity on ovary diameter at anthesis of the cultivars was highly significant (r2 = 0.92**; ÿ = 22.5X - 0.3). Continuous root …

G90-1003 Maximizing Feed Intake For Maximum Milk Production, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide emphasizes the importance of maximizing feed intake for maximum milk production, and management practices which stimulate feeding activity by dairy cattle.

The goal of most dairy producers is to maximize milk production in a cost-effective manner. On the typical dairy farm, feed costs represent nearly 50 percent of the total milk production cost. Economically, it is important to maximize feed intake, improve efficiency of feed use, and lower feeding costs. Many dairy producers fail to realize that there is more involved with properly feeding a dairy cow than looking at a computer printout of a balanced ration. With …

Analysis Of The Fall And Winter Diet Of The Bobcat In Eastern Arkansas, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Food habits of the bobcat (Felis rufus) in eastern Arkansas were examined based on stomach contents of 148 specimens. Rabbits (Sylvilagus floridanus and S. aquaticus) were the primary food source for males, females, and kittens. Rice rats (Oryzomys palustris), nutria (Myocastor coypus), and several species of waterfowl are first reported as food of bobcats in Arkansas. Cotton rats (Sigmodon hispidus) and muskrats (Ondatra zibethica) were more common in bobcat diets in eastern versus western Arkansas. Adult males did not use smaller prey but this food source was common, in kittens; females were intermediate in their use of smaller prey.

Alternatives To And Reduction Of Animal Use In Biomedical Research, Education And Testing, John M. Frazier, Alan M. Goldberg

Experimentation Collection

Biomedical endeavours can be divided into three major categories: research, education, and testing. Within the context of each of these categories, activities involving whole animals have made major contributions and will continue to do so in the future. However, with technological developments in the areas of biotechnology and computers, new methods are already reducing the use of whole animals in certain areas. This article discusses the general tissues of alternatives and then focuses on the development of new approaches to toxicity testing.

Prediction Of Zinc Deficiency In Navy Beans (Phaseolus Vulgaris) By Soil And Plant Analyses, J. D. Armour, A. D. Robson, G. S.P. Ritchie

Food Science and Nutrition

Navy beans (Phaseolus vulgaris cv. Gallaroy) were grown with 7 rates of zinc (Zn) in a Zn-deficient gravelly sandy loam in a glasshouse experiment. The plant shoots were harvested 31 days after sowing and the Zn concentration in each of 4 plant parts (YL, young leaf; YOL, young open leaf; YFEL, youngest fully expanded leaf; and whole shoots) was related to the fresh weight of the shoots. The critical Zn concentrations (mgtkg) in the plant parts determined by the 2 intersecting straight lines model were 21.1 for YL (r² = 0.66), 17.1 for YOL (r² = 0.83), …

Extractable Zinc In Particle Size Fractions Of Soils From Western Australia And Queensland, J. D. Armour, G. S.P. Ritchie, A. D. Robson

Food Science and Nutrition

The zinc (Zn) content of particle size fractions of 12 mainly Zn deficient soils was measured by extraction with three contrasting extractants. The soils, which ranged from sands to a black earth, were from Western Australia and Queensland and particle size fractions (clay, silt, fine sand, coarse sand) were obtained by sieving and sedimentation after ultrasonification of soil suspended in deionized water. The extractants were concentrated HNO₃/H₂SO₄/HClO₄ (acid extractable or AE-Zn), DTPA and 0.002 M CaCl₂. For each extractant, Zn contents of the fractions and whole soils were correlated with organic …

Bacterial Gill Disease Of Freshwater Fishes, G. L. Bullock

United States Fish and Wildlife Service: Publications

Fish gills function as both respiratory and excretory organs. Basically they consist of a network of capillaries where blood is separated from the surrounding water by only one or two layers of cells. Proliferation of epithelial tissue, and later the loss of surface by the clubbing and fusing of lamellae, impair respiration and the excretion of nitrogenous waste materials, and disturb osmotic balance. Because these changes adversely affect the health of fish, the prevention and treatment of gill diseases are important in fish culture. Pathologic changes in gill tissues have been divided into five categories: (1) bacterial gill disease (BGD) …

There was increased production of Verano up to the maximum fertilizer level. Both varieties responded in the second year to residual P following application in the first year but there were no responses in subsequent years.

Conditioned Flavor Aversion: A Mechanism For Goats To Avoid Condensed Tannins In Blackbrush, Frederick D. Provenza, Elizabeth A. Burritt, T. P. Clausen, J. P. Bryant, P. B. Reichardt, Roberto A. Distel

Behavioral Education for Human, Animal, Vegetation, and Ecosystem Management (BEHAVE)

It has been hypothesized that herbivores instinctively avoid tannin-containing plant parts in response to the adverse effects of tannins on forage digestion. However, we found that goats learned to avoid condensed tannins (CTs) from blackbrush current season's growth by associating the flavor of foods containing CTs with aversive postingestive consequences. The aversive consequences experienced by goats apparently are not related to digestion inhibition and may depend on the structure of CTs and on how CTs are bound with other cell constituents. These observations suggest several areas of inquiry related to the interaction between CTs and herbivores. A better understanding of …

What is a Coalition?

1. A coalition is a group of organizations and individuals working together for a common purpose. There are two types of coalitions:

2. "One issue" or event coalitions only have to agree on one particular issue. The coalition is dissolved when the issue has been solved or the event has been coordinated.

"Multi issues" coalitions have related issues, such as nutrition and health, child care needs, elderly health care, or the environment. This more permanent type of coalition recognizes the value of mobilizing together for …

Seed Phosphorus : Its Effect On Plant Production, Mike Bolland, Mike Riley, Brett Thomson, Blakely Paynter, Mike Baker

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

The amount of phosphorus in the seed of annual crop and pasture species influences production of plants grown from that seed. It appears the more phosphorus there is in the seed, the better the potential yield irrespective of whether fertilizer phosphorus is applied to the soil or not. This article discusses the influence of phosphorus concentration in the seed of annual crop and pasture species on subsequent production. It also explains the difference between phosphorus concentration and phosphorus content in the seed

Fisheries Research Report No. 87 - The Recreational Marron Fishery In Western Australia, Summarised Research Statistics, 1971-1987, N. M. Morrissy, C. J. Fellows

Fisheries Research Reports

The freshwater crayfish Cherax tenuimanus, called marron, provides an important recreational fishery in the south-west of Western Australia. The annual fishing catch and fishing effort have been monitored by a log book research programme and an end-of season telephone survey since the 1971/72 season.

Following the 1986/87 fishing season, the fishery remained closed for two seasons (1987/88 and 1988/89) to permit stocks to recover from the effects of high total fishing effort and unfavourable water conditions over the preceding seasons

This paper provides a detailed account of the catch and effort statistics to the close of the 1986/87 fishing season, …
