B803: The Effects Of Juice Extraction Methods On The Quality Of Low-Calorie Blueberry Jellies, Tom C.S. Yang

Bulletins

Juice extracted from lowbush blueberries was used to prepare a low-calorie jelly. Extraction methods included cold-extraction, hot-extraction, and enzyme-extraction. Enzyme-extraction produced the highest yield and least viscous juice with lighter and redder color than other extraction methods whereas hot-extracted juice had an intermediate yield, greatest viscosity and darkest color. Cold-extracted juice made the hardest jelly. Jellies prepared from cold-extracted and enzyme-extracted juices were darker and had a more intense purple color than the corresponding juices, whereas jelly prepared from hot-extracted juice was lighter and redder in color than its corresponding juice.

Explorations — A Journal of Research

Welcome to the first issue of Explorations, A Journal of Research at the University of Maine at Orono.

Join us as we explore a representative selection of the pure and applied research of our faculty. At UMO, we believe that research can capture the imagination and invigorate the mind, as well as contribute directly to the quality of life of the citizens we serve.

In this first issue, we have selected four areas of research that span the disciplines of biological and environmental sciences and the arts. This is but a small part of the research conducted by the faculty …

B802: Base-Age Invariant Polymorphic Site Index Curves For Even-Aged Spruce-Fir Stands In Maine, Bret P. Vicary, Thomas B. Brann, Raph H. Griffin

Bulletins

The spruce-fir forest cover type, occupying nearly 8 million acres in Maine, accounts for approximately 50 percent of the growing stock volume in the State. A similar portion of Maine's commercial forest land is owned and managed by forest industry, with spruce and fir being the mainstay of the industry.

Analyses in recent years of Maine's timber supply have shown softwood removals to exceed growth. The dramatic effects of the spruce budworm (Choristoneura.fumiferana (Clemens)) on the spruce-fir forest of Maine has heightened concern over the timber supply. A greater emphasis on management is necessary if timber growth is to keep …

B792: The Development Of The Ability To Select For Increased Milk Production: The Jersey Dairy Cow In Maine, 1900-1984, John R. Paton, Barbara A. Barton

Bulletins

Histories of dairying and dairy farming usually pass over one very important topic, the point of origin herself: the dairy cow. In the past 150 years, the period associated with the rise of commercial dairying in the U.S., she has not been a static creature. The story of her development is an important and exciting part of the history of dairying, but this development cannot be explained by such phrases as "feeding and management improved" or "breeding improved " . Since the dairy cow of the 1980s is not the same dairy cow of the 1830s, we should understand how …

Bulletins

Cooperative potato clone and variety trials were conducted at 23 locations to determine field, storage, and processing behavior of selected clones and varieties grown under soil, climatic, and cultural management common to the potato growing areas of 13 cooperating states and the Province of New Brunswick, Canada. These tests are all contributions to Regional Project NE107 entitled, "Breeding and Evaluation of New Potato Clones for the Northeast." The primary objective of this project is to determine clone stability over a wide range of soil, climate, and cultural conditions.

Tb113: A Field Test Of Mating-Suppression Using The Spruce Budworm Sex Pheromone, J. B. Dimond, D. G. Mott, W. P. Kemp, J. H. Krall

Technical Bulletins

Spruce budworm sex pheromone was dispersed from aircraft over forest land in Maine in late June, 1980. A major goal was to sample pheromone concentrations in air to determine whether the formulation would provide the steady, sustained release of chemical believed required for interfering with the mating process of the moths. Since pheromone was going to be applied for purposes of analyses of air, we believed we should also study some behavioral effects on spruce budworm populations. The principal body of data involved the ability of male budworm moths to orient to point sources of pheromone in pheromone-treated and untreated …

Tb112: Chemical Control Of The Spruce Budmoth, Zeiraphera Canadensis Mut. And Free. (Lepidoptera: Olethreuthidae) On White Spruce In Maine, J. A. Holmes, E. A. Osgood

Technical Bulletins

The principle objectives of the current study were to determine through preliminary qualitative surveys, the distribution, abundance, and species composition of budmoth in Maine; and to gain satisfactory control of the budmoth through the proper timing of insecticides.
