Tb203: Recent Advances In The Biology And Genetics Of Lowbush Blueberry, Daniel J. Bell, Lisa J. Rowland, John Smagula, Frank Drummond

Technical Bulletins

For lowbush blueberries, this publication presents an in-depth look at the biology and genetics of lowbush blueberry. The authors provide details on its genetic composition and the outline the usefulness of various biochemical, genomic, and other markers in studying the plants genetic structure. The authors also provide an overview of the plant’s economic value to Maine, nutritional value, and its life history.

Tb202: Composition And Biomass Of Forest Floor Vegetation In Experimentally Acidified Paired Watersheds At The Bear Brook Watershed In Maine, Peter Kenlan, G. B. Wiersma, A. S. White, I. J. Fernandez Sep 2009

Tb202: Composition And Biomass Of Forest Floor Vegetation In Experimentally Acidified Paired Watersheds At The Bear Brook Watershed In Maine, Peter Kenlan, G. B. Wiersma, A. S. White, I. J. Fernandez

Technical Bulletins

The percentage cover (abundance), frequency of occurrence, biomass, species richness, and species diversity of understory herbs was measured on a paired watershed ecosystem in eastern Maine, USA. This paired watershed site (Bear Brook Watershed in Maine, BBWM) has had the West Bear Brook Watershed treated bi-monthly with granular ammonium sulfate at a rate of 28.8 kg S ha-1 yr-1 and 25.2 kg N ha-1 yr-1 since 1989. East Bear Brook Watershed serves as the reference site. More than 100 plots were randomly located across the two watersheds. The data suggest that there is generally a lower frequency of occurrence of …

Tb201: Comparison Of The Efficacy Of Sodium Acid Sulfate And Citric Acid Treatments In Reducing Acrylamide Formation In French Fries, Byungchul Kim, L. Brian Perkins, Beth Calder, Lawrence A. Leblanc Jun 2009

Tb201: Comparison Of The Efficacy Of Sodium Acid Sulfate And Citric Acid Treatments In Reducing Acrylamide Formation In French Fries, Byungchul Kim, L. Brian Perkins, Beth Calder, Lawrence A. Leblanc

Technical Bulletins

Two acidulant food additives, sodium acid sulfate (SAS) and citric acid, were investigated for their effectiveness in reducing acrylamide formation in french fries. Acrylamide concentration was determined by gas chromatography-mass spectrometry (GC-MS) after cleanup of french fry extracts by passage through a C-18 column and derivitization by bromination. At a frying temperature of 180°C, both acidulants appeared ineffective, possibly due to the rapid rate of acrylamide formation, which surpassed the capacity of the acidulants to protonate acrylamide intermediates. At the lowest frying temperature tested (160°C), 3% SAS and 3% citric acid significantly (P < 0.05) inhibited acrylamide formation as compared to the control. However, 3% SAS appeared to inhibit acrylamide formation more effectively than citric acid at 160°C, as well as at frying temperatures of 170 and 180°C. Our results indicate that acrylamide formation during frying can be reduced by treatment of potatoes with 3% SAS or citric acid, but SAS, a stronger acid with a lower pKa, is the more effective acidulant.

Performance Of Small-Fruited Pumpkin Cultivars In Maine, David T. Handley, Mark G. Hutton, Gregory J. Koller Jan 2009

Performance Of Small-Fruited Pumpkin Cultivars In Maine, David T. Handley, Mark G. Hutton, Gregory J. Koller

Cooperative Extension - Agriculture

A small-fruited (2-4 lb) or “pie” type pumpkin variety trial was established in the spring of 2009 at Highmoor Farm in Monmouth, ME. Three replications of seven varieties were direct-seeded on 18 June through black plastic mulch. Plots were 18 feet long with three feet between plants and six feet between rows. All fertilizer was applied according to soil test recommendations and incorporated prior to mulch application and seeding. Fruit were harvested on 18 September. Top performing varieties in terms of yield per plot included ‘Chucky’, ‘Small Sugar’, and ‘Field Trip’. ‘Fall Splendor’ produced the largest fruit in the trial, …

B852: Organic Wild Blueberry Production, Frank Drummond, John Smagula, Seanna Annis, David Yarborough Jan 2009

B852: Organic Wild Blueberry Production, Frank Drummond, John Smagula, Seanna Annis, David Yarborough

Bulletins

Recent research carried out under the auspices of a USDA organic transition grant resulted in a better understanding of the interaction of wild blueberry production tactics such as pruning method, soil pH reduction by sulfur (S) application, and organic fertilizer rates on wild blueberry growth, development, and yield. This bulletin is the product of what we have learned over the past four years of this research project.
