Identification Of Poinsettia Cultivars Using Rapd Markers, Jing-Tian Ling, Roger Sauve, Nick Gawel

Agricultural and Environmental Sciences Faculty Research

Randomly amplified polymorphic DNA (RAPD) techniques were used to compare the DNA from leaf tissues of nine commercial poinsettia (Euphorbia pulcherrima Wild ex Klotzsch) cultivars. Amplification occurred in 57 out of 60 (95%) tested primers. Nine primers that revealed polymorphisms among cultivars were selected for further evaluation. Forty-eight RAPD bands were scored from these primers, and 33 (69%) were polymorphic. All tested cultivars could be discriminated with seven bands generated from primers OPB7 and OPC13. Results of a UPGMA cluster analysis and principal components analysis placed the nine cultivars into two groups: one group consisted of `Jingle Bells', `Supjibi', …

Behavior Of Female Eretmocerus Sp. Nr. Californicus Howard (Aphelinidae: Hymenoptera) Attacking Bemisa Argentifolii Bellows And Perring (Aleyrodidae: Homoptera) On Two Native Californian Weeds, David H. Headrick, Thomas S. Bellows, Jr., Thomas M. Perring

Horticulture and Crop Science

Searching and ovipositional behaviors by female Eretmocems sp. nr. californicus Howard on Bemisia argentifolii Bellows and Perring infesting velvetleaf, Abutilon theophrasti Medic. (Malavaceae), and telegraph weed, Heterotheca grandiflora Nutt. (Asteraceae), were quantified. Adult female behaviors were described and quantified for E. sp. nr. californicus to establish a behavioral time budget analysis. Females departed from leaves of A. theophrasti in 83.3% of the trials, and of those that remained and searched for hosts, walking speeds averaged 0.29 mm/s. Females departed from the leaves of H. grandiflora in 44.4% of the trials, and those remaining readily searched for whitefly hosts with walking …

An Evaluation Of Mango (Mangifera Indica L.) Cultivars And Their Commercial Suitability For The Kimberley, P. R. Johnson, D. M. Robinson

Horticulture published reports

An evaluation of 74 mango cultivars was conducted from 1983 to 1995 in the Ord River Irrigation Area (ORIA) on Cockatoo sand. The aim to determine their suitability for commercial production and establish the basis for a mango industry in the Northern tropics of Western Australia. Measurements were made on yield, harvest times, flowering times, brix, fruit quality, growth rates and market acceptability. Results have indicated that cultivars, other than Kensington Pride, most commercially suitable in the ORIA are Banana for early cropping in mid September, Irwin for high regular yields and good market acceptability, Haden for excellent market acceptability, …

International Market Opportunities For Lentils, Andrew Quinn, Malcolm Sedgwick

Farm Systems and Economics published reports

The purpose of this report is to determine, through desk top statistical analysis, those countries which hold significant promise for the export expansion of the Western Australian lentil industry.

The report is comprised of five parts. 1) a brief lentil overview, 2) world lentil production and trade, 3) Australian lentil production and trade, 4) Western Australian lentil production and trade and 5) conclusions.

The first four sections identify the major producers, exporters, importers and premium markets operating in the international lentil market. The fifth section concludes by identifying six countries that warrant further in-market analysis to determine their lentil preferences …

Molecular And Functional Characterization Of A Novel Low-Affinity Cation Transporter (Lct1) In Higher Plants, Daniel P. Schachtman, Raman Kumar, Julian I. Schroeder, Ellen L. Marsh

Department of Agronomy and Horticulture: Faculty Publications

The transport of cations across membranes in higher plants plays an essential role in many physiological processes including mineral nutrition, cell expansion, and the transduction of environmental signals. In higher plants the coordinated expression of transport mechanisms is essential for specialized cellular processes and for adaptation to variable environmental conditions. To understand the molecular basis of cation transport in plant roots, a Triticum aestivum cDNA library was used to complement a yeast mutant deficient in potassium (K⁺) uptake. Two genes were cloned that complemented the mutant: HKT1 and a novel cDNA described in this report encoding a cation …

International Market Opportunities For Faba Beans, Andrew Quinn, Malcolm Sedgwick

Farm Systems and Economics published reports

Western Australian faba bean production is growing and export volumes are increasing. In contrast, production is declining in many of the world's traditional faba bean regions. World trade, however, is growing.

China dominates the world export market and is growing rapidly as an exporter. The UK and Australia are the second and third largest exporters respectively.

As Western Australian production increases, the State will increasingly play an important role in Australia's ability to supply faba beans into markets looking tor quality and stable supply.

Saudi Arabia has emerged as the State's largest export market. The State is well located to …

Soil Temperature And Fumigation Effects On Plant Phosphorus Uptake And Related Microbial Properties, Dennis L. Mccallister, L. A. Jawson, M. D. Jawson

Department of Agronomy and Horticulture: Faculty Publications

Early season problems with growth of corn (Zea mays L.) under cool, wet conditions prompted a study of the effects of soil and environmental conditions on mineralization and plant uptake of phosphorus (P). Our objective was to determine the effect of soil test P, temperature, and soil fumigation on soil P availability and uptake during early corn growth. Corn was grown in growth chambers at temperatures of 14°C or 25°C. Soils were a high-P Hastings silty clay loam (fine, montmorillonitic, mesic Udic Argiustoll) and a low-P Sharpsburg clay loam (fine, montmorillonitic, mesic Typic Argiudoll). Plants grew for up to …

Notes: Forage Yield, Quality, And Fertility Of Sorghum X Sudan Grass Hybrids In A1 And A3 Cytoplasm, Jeffrey F. Pedersen, J. J. Toy

Department of Agronomy and Horticulture: Faculty Publications

Currently, no information is available comparing the agronomic performance of A1 and A3 cytoplasms in sorghum x sudangrass [Sorghumbi color (L.) Moench] hybrids. The objectives of this study were to compare the effects of A1 and A3 cytoplasm on the maturity, fertility, height, forage yield, and forage quality of sorghum × sudangrass hybrids. In 1989, pollen from a bulk of eight sudangrass populations was used to pollinate four sorghum lines that had been male-sterilized in both A1 and A3 cytoplasm. Hybrids were grown at the Univ. of Nebraska Field Laboratory Ithaca, NE, in 1990 and 1991, in a split-plot …

The research reports in this publication represent one year of results; therefore, these results should not be used as a basis for long-term recommendations. Several research reports in this publication dealing with soil fertility also appear in Arkansas Soil Fertility Studies 1995 , Arkansas Agricultural Experiment Station Research Series 450. 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.

Issues Concerning The Eradication Or Establishment And Biological Control Of The Mediterranean Fruit Fly, Ceratitis Capitata(Wiedemann) (Diptera: Tephritidae), In California, David H. Headrick, Richard D. Goeden

Horticulture and Crop Science

Classical biological control is suggested as a tool worth developing now for possible future use in the integrated pest management of the Mediterranean fruit fly (Medfly), Ceratitis capitata (Wiedemann), in California. Three factors that impact broadly on developing and implementing such a biological control program are: (1) the question of Medfly establishment, (2) quarantine considerations, and (3) agricultural and urban concerns. Each of these factors and their combined effects must be considered when discussing biological control of Medfly in California as shaped by historical perspectives on Medfly invasions, methods of Medfly eradication, and past biological control efforts against Medfly. We …
