Laboulbeniales On Semiaquatic Hemiptera. Iii. Rhizopodomyces, Richard K. Benjamin

Aliso: A Journal of Systematic and Floristic Botany

Thaxter's original description of Rhizopodomyces is emended to reflect new information gained from a study of not only the type species, R. merragatae, but also of six additional species described as new, R. basifurcatus, R. californicus, R. erectus , R. geniculatus, R. mexicanus, and R. polhemusii. All of the species have been found on semiaquatic bugs of the family Hebridae (Hemiptera). The female thallus of Rhizopodomyces spp. consists of a simple, two-celled receptacle, the suprabasal cell bearing a one-celled primary appendage and giving rise usually to a single, longstalked perithecium. The male thallus initially consists of …

Erosion Risks With High Stocking Rates At Kojonup Trial, Department Of Agriculture, Western Australia

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

A pasture grazing trial at Kojonup dramatically illustrated the effects of Cyclone Alby. Severe erosion was evident on the heavily stocked plots while the more lightly stocked plots showed little damage.

Options For Machinery And Labour, A F. Herbert

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

Machinery is one of the highest costs in farming today. It is not unusual for capital investment in machinery to be 20 to 30 percent of the total investment in the farm.

On an annual basis, expenditure directly attributable to machinery can be 40 per cent or more.

This article cannon be a panacea for everyone to reduce machinery costs - each farm is different. But some of the issues might be of help.

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

Tractor and implement matching involves balancing implement load characteristics with tractor output characteristics to obtain the best output from the combination. Too much or too little can be costly.

Getting The Best From Tractor Tyres, J Quealy

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

The amount of pull a tractor develops depends largely on tyre efficiency and so with so many tyre size options for the one tractor model it is very easy to make the wrong decision on tyre fitment.

Tyre efficiency varies with tractor weight, soil conditions, inflation pressure and tyre size.

Hers we look at some of these factors and how changing them may affect efficiency.

Planting Trees-Why Rather Than How, Angelo Cohn

Journal of the Minnesota Academy of Science

Three evergreen plantings over 25 years in a private woodland are described and evaluated in terms of reforestation, economics and personal satisfaction. Credit is given to government foresters and support from the Minnesota Department of Natural Resources (DN\R) and the federal Forest Incentives Program (FIP). Changes in site preparation methods, selection of species and planting procedures are discussed as outcomes of research and field experience. Cost-benefits are assigned principally to human values reflected in family learning and enhanced appreciation of the ecosystem of rural Minnesota.

Photoperiodicity In Adsuki Beans, A Preliminary Report, Thomas W. Clapp, Vivian L. Johnson

Journal of the Minnesota Academy of Science

One variety, Adsuki beans (Phaseolus angularis or Vigna angularis) has been demonstrated to be photoperiodically sensitive, flowering within fifty days or in the three to five internode stage when grown under "short day" conditions and remaining vegetative for at least 70 days or past the 12 internode stage under "long day" conditions.

Lichen Deterioration About A Coal-Fired Steam Electric Generating Plant, Elmer L. Schmidt, R. J. Zeyen

Journal of the Minnesota Academy of Science

A survey of three common epiphytic species of foliose lichens was conducted about a coal-fired steam electric station in North-central Minnesota during the summer of 1977 to assess general lichen health on a gradient basis from a point-source of air pollution. Health, as judged by abnormal form and color, of nearly 3,500 lichen specimens was recorded in 35 vegetation survey plots from a total of 291 trees. Lichen discoloration and degeneration decreased with increased distance from the power plant, and little deterioration was observed beyond 3 miles. Within the plant vicinity, lichen damage was noted on tree boles facing the …

Lake Itasca State Park Myxomycetes: An Annotated Checklist, M. E. Palm, E. L. Stewart, E. F. Haskins

Journal of the Minnesota Academy of Science

A lack of published information regarding Minnesota Myxomycetes prompted attempts to document species from Lake Itasca State Park in Clearwater county, in the northwest part of the state. Seventy-five species are herein recorded from 341 collections made during the years 1959, 1971,and 1975-78.

In Vitro Experiments On Totipotency Of Dacus Carota, Karl L. Ruser

Journal of the Minnesota Academy of Science

The intent of this project was to induce the totipotency of carrot cells in tissue culture. The information gathered would be applied to work with woody plants. Differentiated cells removed from the root were cultured in vitro using a modified White's medium. Callus was initiated and successfully sub cultured. Roots and the production of chlorophyll have been initiated in the cultures. Because some specialized equipment and facilities for tissue culture were not available at the beginning of the project, it took considerable time to gather and improvise them. A roller tube culture mixer was constructed, using the mechanism from a …

Contour Cultivation : Cheap Erosion Control, T R. Negus, B. Barrett

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

Although the benefits of contour cultivation are well recognised, it makes cultivation more difficult, particularly if the paddock is split by contour banks and grassed waterways. However, a comparison east of Pingelly indicates that contour cultivation is little more expensive or time-consuming than ordinary cultivation.

Fumigating A Farm To Control Grain Insects, J H. Moulden

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

During the past year, two major projects for control of grain insects were organised on Western Australian farms. Both excercises aimed to eradicate grain pests which would have seriously threatened grain exports if they had become established.

The fumigation was done jointly by the Entemology branch of the Department of Agriculture, and the Agricultural Protection Board.
