GOOD storage conditions are vitally important for retaining the germinating capacity of seeds.

Vermin Symposium Report : Wanted : A New Approach To Rabbit Control, A R. Tomlinson

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

THE main reason why rabbits have not increased as rapidly as their amazing capabilities might have led people to expect has been a series of years not suitable for full breeding.

This has been more important than myxomatosis and "1080". This was one of the thoughts taken away by those who attended the rabbit control symposium held in Perth recently.

Bacterial Blight Or Black Spot Of Walnuts, O M. Goss, R. F. Doepel

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

Bacterial blight is the most important disease of walnuts in Western Australia.

In bad seasons it can cause heavy losses in susceptible varieties such as Wilson's Wonder, and in some seedling trees.

Carefully timed sprays greatly reduce the incidence of bacterial blight, and it is also recommended that less susceptible varieties—such as Franquette— should be used for new plantings.

Plant Diseases In Western Australia, S C. Chambers

Spread Super For Cereal Crops, T E. Mcdowell, J. A. C. Smith, W. J. Toms, M. D. Carroll

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

THE use of bulk superphosphate broadcast direct on to the paddocks is a new method of reducing fertiliser costs.

But it has long been known that broadcasting phosphate is less efficient than drilling it in with the seed.

The experiment reported here was designed to demonstrate this point.

Stoneville Research Station Horticulture Field Day, Department Of Agriculture, Western Australia

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

THE experimental programme at the Department of Agriculture's Horticultural Research Station at Stoneville was on show when the station's first full-scale field day was held this spring.

About 100 fruitgrowers saw the progress made in development of the station and its research programme, and discussed the experiments with the experts concerned.

Vibrionic Dysentery Of Pigs, M R. Gardiner

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

VIBRIONIC DYSENTERY of pigs, also known as porcine vibriosis and swine dysentery, has been recognised for many years in the U.S.A. It was first reported in Australia in 1938, in South Australia, and later in both Victoria and New South Wales.

This brief description of a disease recently diagnosed for the first time in Western Australia is given so that breeders have some chance of recognising it in their herds. Suspected cases should be reported without delay.

Antibiotic Residues In Milk : The Farmer's Responsibility, N Ingleton

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

THE LEVEL of antibiotic residues in commercial milk supplies has been steadily increasing over the past few years.

These residues find their way into the bulk milk as a result of milk from cows under antibiotic treatment for mastitis or other infections being included in the bulk milk for sale.

Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

SUMMARY

Good stable soil structure is valuable for promoting the growth of plants and micro-organisms by permitting enhanced aeration and water penetration and by decreasing erosion under some conditions.

Micro-organisms influence water percolation through the soil. They may plug up soil pores with byproducts of growth and reduce water percolation. On the other hand, if a soil containing a large amount of microbial products is stirred and allowed to dry, then the percolation may be high.

Micro-organisms are involved in stabilizing soil structure by their products of decomposition and their cellular binding material, such as mycelia. Microorganisms differ greatly in …

Assay Of Cis And Trans-O-Hydroxycinnamic Acids In Sweetclover Extracts, Francis A. Haskins, H. J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

Various investigations related to the biosynthesis of o-hydroxycinnamic acid in sweetclover require that simple, rapid methods of assay be available for both the cis isomer (coumarinic acid) and the trans isomer (o-coumaric acid). This report deals with two such methods, both of which represent refinements of a technique for the fluorometric assay of coumarin described in an earlier publication from t h i s laboratory a ask ins and Gorz, 1957). In one procedure, designatled method I, o-coumaric acid and total o-hydroxycinnamic acid are determined, and coumarinic acid is estimated by difference; while in the other procedure, method 11, coumarinic …

Pensternon In Your Garden, Glenn Viehmeyer

Department of Agronomy and Horticulture: Faculty Publications

A new race of hardy perennials is beginning to appear in American gardens. These are the penstemons, a genus of plants closely related to the familiar snapdragon, which may become important ornamentals as they become better known to gardeners. The purpose of this bulletin is to show the possibility of the genus as an ornamental and to suggest species and species hybrids of possible value to Great Plains gardeners; to provide information about propagation and culture; and to encourage gardeners to engage in penstemon breeding as an avocation.

Toxic Annuals In Horticulture, Robert Dunlop Royce

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

THE number of poisonous shrubs and trees that are grown in gardens is very great, and several of these species have been discussed in detail.

It is probable that few people realise just how many of the commonest garden plants are in some way or under some circumstances, likely to contain a toxic principle.

Furthermore, this is not confined to the longer lived plants, but it applies equally to the annual plants, both summer growing and winter growing.

Wheat Quality, Department Of Agriculture, Western Australia

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

IN August, 1956, the Australian Agricultural Council agreed that, as a first step in the further examination of all aspects of the subject of wheat quality in Australia, a conference of all interested parties should be convened by the Department of Primary Industry.

Stocking Rate And Pasture Management, B F. Carlin

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

FARMERS west of the Great Southern Railway, raising sheep and beef cattle, frequently associate soil deficiencies with difficulties in holding sub. clover in their pastures.

Field observations and some trials in those districts indicate that in many paddocks the problem arises through undergrazing rather than a deficiency in the soil.

Wheat Variety Trials On Research Stations, J T. Reeves, J. L. Mcmullan

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

THE results of wheat variety trials at seven Research Stations in the medium and low rainfall areas for the years 1957, 1958 and 1959 are presented and discussed.

The trials are designed to give information on yield and flour quality of promising crossbreds originating from local breeding programmes and newly produced varieties from other parts of Australia.

Large scale variety trials are the final tests in the long process of selection and testing which is essential before a new crossbred can be released.

The new wheats are compared with standard ones under different conditions of soil and climate.

Evolutionary Relationships Among The North American Mallards, Paul A. Johnsgard

Papers in Ornithology

A comparative morphological, behavioral, and electrophoretic study was undertaken on six populations of North American mallards that are currently considered by the A.O.U. Check-list to comprise four species and two additional subspecies. These include Anas p. platyrhynchos, A. d. diaxi, A. d. novimexicana, A. f. fulvigula, A. f. maculosa, and A. rubripes. These forms are essentially allopatric in their breeding distributions, with the major exception of A. p. platyrhynchos and A. rubripes, which overlap throughout a several-hundred-mile zone in east-central United States.

Geographic ranges and population sizes are estimated, and evidence is presented to indicate that the …

Notes On The Collared Pika, Ochotona Collaris (Nelson), In Alaska, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Maps showing the geographic range of the collared pika, Ochotona collaris (Nelson), have been published recently by Hall (1951) and by Hall and Kelson (1959). According to these, this mammal occurs in the mountains between the Tanana and Yukon Rivers, and in the Alaska Range as far west as Mt. McKinley. A specimen from the summit of the Chugach Mountains (Baker, 1951) was not included on the aforementioned maps. Osgood (1904) referred to two specimens collected by C. L. McKay in the Chogmit Mountains, east of Lake Clark at the base of the Alaska Peninsula, and also mentioned a sight …

Mortality Of Eastern Brook Trout Caused By Plerocercoids (Cestoda: Pseudophyllidea: Diphyllobothriidae) In The Heart And Viscera, Glenn L. Hoffman, C. E. Dunbar

United States Fish and Wildlife Service: Publications

It is well known that migrating helminth larvae do a great amount of damage to the host. Often, however, the host is relatively large and the damage done by few larvae is not serious. When the host is very small the mechanical damage, at least, must be proportionately greater for each larva present. An unusual case of mortality of small brook trout (Salvelinus fontinalis) roughly 2 to 4 inches long was brought to our attention. Examination of the mortalities, as well as survivors, revealed relatively large diphyllobothrid larvae (fig. 1) in the chambers of the heart, liver, pericardial …

Notes On Sanguinicola Davisi (Trematoda: Sanguinicolidae) In The Gills Of Trout, H. S. Davis, Glenn L. Hoffman, E. W. Surber

United States Fish and Wildlife Service: Publications

In 1953 the late Dr. Davis recorded the presence of an unnamed trematode from the gill blood vessels of fingerling cutthroat trout (Salmo clarki) and fingerling steelhead trout (Salmo gairdneri) at the Alsea Hatchery and in yearling rainbow trout (Salmo gairdneri) at the Oakridge Hatchery, both of the Oregon State Game Commission. Subsequently, two blood flukes, Sanguinicola davisi and S. klamathensis, were described from trout by Wales (1958). The present species was determined to be S. davisi by one of us (GLH). This report supplements data reported by Davis (1953) and Wales (1958). …

Activities Of Acid Phosphatase, Peroxidase, And Polyphenolase In Etiolated Shoots From Control And Irradiated Maize Seeds, Francis A. Haskins, S. C. Downs

Department of Agronomy and Horticulture: Faculty Publications

Evidence is presented that enzymatic differences exist between etiolated shoots from appropriately irradiated maize seeds and shoots from control seeds. Differences in specific activities of acid phosphatase and peroxidase became apparent only when individual portions (first internode, coleoptile, and unexpanded foliage leaves) of the shoot were considered. Contributions of the three shoot portions to total activities of acid phosphatase, peroxidase, and polyphenolase also were studied, and irradiation-induced differences in the patterns of contribution were noted.

The Biology Of Karyolysus Dilloni N. Sp. From Rana Aurora Draytoni, Wayne Aldo Sorsoli

University of the Pacific Theses and Dissertations

While investigating various Amphibia of Central California for blood inhabiting parasites, the writer found a parasite in the blood of the Rod-legged Frog (Rana aurora draytoni) which exhibited the characteristics of Karyolysus, yet was different from any described; this same parasite had been previously observed by Dr. D. L. Lerhmann, Associate Professor of Zoology, University of the Pacific. In order to increase the knowledge of this form, further investigations were undertaken.

The first step was to determine the life cycle in the vertebrate host and, if possible, to find the invertebrate host and to elaborate the developmental stages in the …

The Taxonomy Of The Anatidae—A Behavioural Analysis, Paul A. Johnsgard

Paul Johnsgard Collection

Delacour & Mayr's (1945) classic revision of the Anatidae took waterfowl behaviour into account to a much larger degree than had any previous classifications of the group. However, their utilization of behaviour was primarily at the tribal and generic levels, and no real attempt was made to use behaviour for determining intrageneric relationships. Thus far only Lorenz (1941, 1951-1953) has seriously attempteq this with waterfowl, and his analysis of the relationships within the genus Anas (sensu Delacour & Mayr) has provided a remarkable insight into the evolution of this group. I have attempted to expand Lorenz's behavioural delineation of relationships …
