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 …

Arkansas Rice Research Studies 1991, B. R. Wells

Arkansas Agricultural Experiment Station Research Series

The research reports in this publication represent one year of results; therefore, these results should not be used as a basis for longterm recommendations. Several research reports in this publication dealing with soil fertility also appear in Arkansas Soil Fertility Studies 1991, Arkansas Agricultural Experiment Station Research Series 421. This duplication is the result of the overlap in research coverage between the two series and our effort to inform Arkansas rice producers of all the research being conducted with funds from the rice check-off.

A Survey Of Mucilaginous Testa In Chamaesyce, Martha S. Jordan, W. John Hayden

Biology Faculty Publications

Seeds of Chamaesyce were studied for presence of mucilaginous testa. Samples were selected to represent all major systematic sections within the genus. Observations were made with a dissecting microscope following brief hydration of seeds; additional SEM observations of both intact and fractured dry seeds were made for selected species. With few exceptions, most of Boissier's subsections test positively for seed mucilage; however, mucilage is generally absent in subsections Gymnadeniae and "Sclerophyllae", for which absence of mucilage is regarded as secondary loss from mucilagionus ancestors. Although mucilage production is associated with a well-defined subepidermal layer of macroesclereids, it is …

Herbicide Trials On Field Crops 1991, Robert Frans, Marilyn Mcclelland, David Jordan

Arkansas Agricultural Experiment Station Research Series

Herbicidal weed control is economically important for production of field crops. Field experiments are conducted annually in Arkansas to evaluate the activity of developmental ancommercial herbicides for selective control of weeds in several important crops. These experiments serve both industry and Arkansas agriculture by providing information on the selectivity of herbicides still in the developmental stage and by comparing the activity of these new herbicides with that of recommended herbicides.

Arkansas Cotton Variety And Strain Tests 1991, F. M. Bourland, J. S. Dacus

Arkansas Agricultural Experiment Station Research Series

Varieties and advanced strains of cotton were evaluated in 1991 by the Arkansas Agricultural Experiment Station. Varieties and some advanced breeding lines were evaluated in the 1991 Arkansas Cotton Variety Test. Entries in the 1991 Commercial Cotton Strain Test included both released varieties that have not been evaluated in Arkansas and advanced breeding lines that may soon be available to producers.

A Complete Index To The Butler University Botanical Studies, A Journal Of Original Research Published By Butler University 1929-1964, Rebecca W. Dolan

Scholarship and Professional Work - LAS

For 35 years, the Botany Department of Butler University published a journal of research conducted by Butler faculty, students. and other Indiana botanists. Many of the papers contain valuable historical studies. especially floristic surveys that document Indiana's vegetation in past decades. This article presents a complete index for the journal. arranged both chronologically and alphabetically. Reprints of articles are still available.

Distribution, Habitats, And Taxonomy Of Ruppia Maritima L. And R. Occidentalis S. Watson In Nebraska, Robert B. Kaul

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Specimens of Ruppia from all eleven Nebraska counties in which it is known fall into two groups: R. occidentalis in alkaline Sandhills waters and R. maritima in saline waters of the Platte River Valley and Lancaster County. Ruppia occidentalis is distinguished by its more robust size; redspotted leaves and stems; terete, entire, obtuse leaves; 4-8(9) carpels; and by two elliptic white spots on its endocarp, among other characteristics. Ruppia maritima is more delicate and unspotted; the leaves are oblate in section, sub-apically denticulate, and acute-acuminate; the carpels are 3 or 4, and the endocarp spots are nearly circular. Both species …

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.

Local Polyploid Variation In The Native Prairie Grass Andropogon Gerardii, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

The microscale distribution of polyploid variants of the dominant grass big bluestem (Andropogon gerardii) in virgin tallgrass prairie was mapped using flow cytometry. The correlation between DNA content and polyploidy allows the use of flow cytometry for nondestructive determination of polyploidy in intact plants. At Konza Prairie, local plots contained from 0 to 100% hexaploid cytotypes but most showed fine-scale mixing of the polyploid variants. The relationship of cytotype frequency to moisture availability or burning history was nonsignificant

The 1991 Field Evaluation Of Herbicides On Small Fruit, Vegetables And Ornamental Crops, R. E. Talbert, R. A. Wichert, V. F. Carey Iii, D. H. Johnson, D. F. Ruff, J. A. Kendig

Arkansas Agricultural Experiment Station Research Series

The establishment of this field-testing procedure provides the chemical industry, through its partial support, and the Arkansas Experiment Station the opportunity to evaluate herbicide performance on small fruit, vegetable and ornamental crops grown under Arkansas conditions. This report also provides a means for disseminating information to interested people and public-service weed scientists.

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 …

'Living Soil' Seminar, Department Of Agriculture, Western Australia

Agriculture reports

Provides an opportunity for farmers and those involved in the agricultural service industry, to focus on what happens in the soil. Seminar reflects the interest detected amongst farmers in knowing more about the things that influence plant growth and a genuine concern about the environment.

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.
