In Vitro And In Vivo Techniques For Screening New Natural Product-Based Fungicides For Control Of Strawberry Anthracnose, Maritza Abril

Dissertations

Seven plant pathogenic fungi (Botrytis cinerea, Colletotrichum acutatum, C. fragariae, C. gloeosporioides, Fusarium oxysporum, Phomopsis obscurans, and P. viticola) valuable in screening fungicide efficacy were tested. Optimal and reproducible conditions for germination of these selected fungi were established by incorporating Roswell Park Memorial Institute 1640 (RPMI) as a medium of known composition and washing conidia to remove innate germination inhibitors. This step reduced average fungal germination times between 3.5 h and 21.2 h. The natural product-based fungicide, sampangine, seven sampangine analogs (4-bromo-sampangine, 4-methoxysampangine, benzo[4,5]sampangine, liriodenine Mel AMC-XIII-103, onychine, cryptolepine, and liriodenine CDH-II-37), plus seven conventional fungicides (benomyl, captan, cyprodinil, fenbuconazole, …

Subcritical Water And Carbonated Water Extraction Of Anthocyanins From Grape Pomace, Lydia Rice, L. R. Howard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Grape pomace, a by-product of juice and wine processing, is a rich source of anthocyanins, antioxidant compounds that may afford protection against cancer and coronary heart disease. Unfortunately, traditional extraction of these antioxidants involves use of organic solvents, which pose serious safety and disposal problems for industry. Clearly a need exists for “green” extraction technologies—such as use of subcritical water—that eliminate or reduce the amount of organic solvents. In this study, we determined the efficacy of subcritical and carbonated water in extraction of anthocyanins from red grape pomace. Extraction variables including particle size, pomace mass, and temperature were optimized, and …

Powdery Mildew In Wine Grapes In Western Australia, Diana Fisher, Trevor Wicks Dr

Bulletins 4000 -

Powdery mildew is caused by the fungal pathogen Uncinula necator. It is the most persistent fungal problem of grapes in WA and one of the most widespread fungal diseases of grapevines in the world. It is characterised by ash-grey to white powdery growth on green tissue of the vine. If uncontrolled it can cause serious crop losses and impair wine quality.

Commercial Irrigation And Nutrition Practices For Strawberries In Western Australia, D. Phillips, D. Gatter, T. Calder, D. Pitman

Horticulture research reports

Irrigation practices employed by five commercial strawberry growers on sandy soils of the Swan Coastal Plain near Perth Western Australia were monitored for two consecutive seasons, 1995 and 1996 during the Spring production period.

Nutritional practices for the same grower group plus one Albany grower were monitored by plant, soil and sap analysis at 14 day intervals throughout the 1996 season.

Irrigation records showed that market quality strawberries could be produced at this time of year (August to December in Perth) on soils with very poor water retention properties with an average crop factor(E Pan) for the season of 0.7 …

Formation And Control Of Chlorophyll, Solanine Alkaloids, And Sprouts Of Potato (Solanum Tuberosum L.) Tubers And Carbonyl Compound Of Tomato (Lycopersicon Esculentum Mill.) Fruits, S. J. Jadhav

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Part I. Formation and control of chlorophyll, solanine alkaloids, and sprouts of potato (Solanum tuberosum L.) tubers

Incorporation of radioactive carbon from acetic acid-2-¹⁴C (sodium salt), β-hydroxy-β-methylglutaric acid (HMG)-3-¹⁴C, L-leucine-U-¹⁴C, L-alanine-U-¹⁴C, and D-glucose-U-¹⁴C into the predominant glycosidic steroidal alkaloids, ⍺-solanine and ⍺-chaconine of potato sprouts was 4.88, 9.0, 15, 24, and 20 times less than that of mevalonic acid (MVA)=2-¹⁴C (DBED salt), respectively. The efficiency ratio revealed that β-hydroxy-β-methylglutaric acid (HMG)-3-¹⁴C was incorporated via acetate or acetoacetate. The distribution of radioactivity originated from D-glucose-U-^{14 …}

An Ecological Study Of Coliform Bacteria Associated With Vaccinium Corymbosum, Harry C. Bittenbender

Honors Theses

Recent research has shown that there are coliform populations associated with the cultivated high bush blueberry, Vaccinium corynbosum. This study is aimed at determining the ecology of these colofirms, as they are related to blueberry production from the farm to the warehouse. Tests will be made to identify the Salmonella group, those associated with "food poisoning." Total bacterial coliform counts will also be made. This paper is primarily an ecological study of the coliforms found on blueberry farms near Grand Junction, though fruit samples were taken from all warehouses of the M.B.G.A.

Growing And Marketing Yates For Profit, Frank Melville

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

THE YATES APPLE is a late maturing red variety which because of its good storage qualities enjoyed a prominent place on the late market for many years.

The trees grow and crop well, the only disabilities are insufficient colour under some circumstances, small size fruit and a tendency to shrivel.

All these troubles can be successfully overcome by appropriate management.

Preserving And Pickling, O. Evans Scott

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

AT this time of the year many housewives wish that fruit trees would bear little and often throughout the year rather than a lot in a comparatively short space of time.

We preserve fruits to try to spread this short period, and to have them on hand to vary menus when fruit is out of season.

A cupboard shelf packed with bottles of colourful, neatly arranged preserved fruits is indeed a satisfying sight.

Bottling is the most popular method, with pickling being done to a smaller extent.
