Fertility Build Up Under Northern Wheatbelt Pastures, M L. Poole

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

Experiments on two farmers' properties demonstrated that legume pastures increase the fertility of northern wheatbelt soils.

Crops on legume pastures had higher yields than crops on volunteer pasture.

The experiments also indicated the most productive legume species for each situation and demonstrated that nitrogen added by legumes has a residual effect in the soil.

Saltland Pastures, C V. Malcolm

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

FOLLOWING THE DEVELOPMENT of Agriculture in Western Australia considerable areas of highly productive land have become salt affected to the degree that normal crops and pastures cannot be grown.*

Estimating Surface Area Of Soybean Root Systems, John B. Carlson

Journal of the Minnesota Academy of Science

A procedure for estimating the total root length, root surface, and root hair surface is described for greenhouse-grown soybeans. Data are presented on the extent of the root systems of 3-week and 14-week old soybeans. The possibility of correlating data from greenhouse-grown soybeans with that of field-grown soybeans as a method to make some predictions on extent of the root systems of field-grown soybeans is suggested.

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.

Dormancy And Life Span Of Saffron Thistle Seeds, B J. Quinlivan, J. R. Pierce

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

RESEARCH in the Geraldton area has indicated that seeds of the saffron thistle (Carthamus lanatus) spread their germination over some seven years but most germinate in the first two years.

Factors influencing the rate of germination and the survival of seeds are the depth of burial and the presence of termites in the soil.

Floral Morphology And Phylogeny In The Hydrocharitaceae, Robert B. Kaul

School of Biological Sciences: Faculty Publications

The vascular anatomy of 13 of the 15 genera of the Hydrocharitaceae has been studied, and certain aspects of floral morphology are considered. The flowers of the family show a broad range of specialized structures combined with primitive characteristics. The origin of paired and single stamens is interpreted as probable modifications of fascicled stamens. Extreme reduction in the androecium is shown for several genera. Tendencies toward reduction and fusion within the gynoecium are pronounced. Most genera are at least slightly syncarpous, but a few are apocarpous. The inferior ovary is appendicular in nature, with some genera exhibiting more complete fusion …

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.

The Dalmation Green Graft, D Mann, H. R. Rodda

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

THE GREEN GRAFT, introduced to the Swan Valley by Dalmatian vignerons many years ago, is carried out in late November or early December, at the stage when the pith of the growing shoot is beginning to whiten.

Because stock and scion are green at this time and the shoots have not started to ripen, the green graft calluses quickly.

Seasonal Chlorophyll Change In A Leafy Liverwort, Richard L. Anderson, Edward Flaccus

Journal of the Minnesota Academy of Science

It is known that chlorophyll content of plant material varies with the season of the year, though the fact is sometimes lost sight of in studies of particular plant communities. Measurement of seasonal changes has been more often done with higher plants: e.g., Compton and Boynton (1945), Bordeau ( 1959). But Myiata and Hosokowa (1961) studied these changes in epiphytic mosses as correlated with photosynthetic efficiency.

This paper reports on a study made during 1963-1964 of the chlorophyll content of the leafy liverwort, Scapania nemerosa (l.) Dumort, measured at monthly intervals for a period of one year. This plant material …

It has yielded more than Prior in all areas.

Subterranean Clover Establishment In The Wheatbelt, M L. Poole

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

Care and attention to detail will greatly increase the chances of establishing good subterranean clover pastures in the wheatbelt.

PASTURE ESTABLISHMENT usually takes second place to cropping in the wheatbelt, with many farmers "bunging in a bit of clover" and hoping for the best. The worst often transpires, with either patchy stands or complete failure resulting.

Using "cheap" methods of establishment is a short-sighted approach and a waste of energy and resources.

Germination And Early Development Of The Silky Prairie Clover, Richard B. Forbes

Journal of the Minnesota Academy of Science

Field and laboratory studies of the silky prairie clover (Petalostemon villosum Nutt.) in central Minnesota indicated that seeds of this plant require scarification but do not require an overwintering period, to germinate. Germination and primary root growth are rapid; shoot growth appears to be quite slow. Methods of associating shoot growth with age are suggested and several notes on the life history of the plant ore presented.
