An Economic Analysis Of Wild Bee Pollination In Lowbush Blueberry Production, Francis A. Drummond

University of Maine Office of Research Administration: Grant Reports

The purpose of this project is to determine the relative economic values of wild bee pollinators and commercial honeybees in lowbush blueberry production for individual Maine farms. The lowbush blueberry requires insect pollination in order to set fruit. Most farmers rent colonies of the non-native honeybee for pollination services, but wild, native bees are also effective pollinators. This project aims to provide growers with the means to assess the pollination needs of individual fields and to understand the levels of pollination possible if honeybees are not available. In order to achieve these goals, the relative abundance and species diversity of …

Production Of Minitubers From Potato Seedlings And Advanced Selections, Benildo G. De Los Reyes

University of Maine Office of Research Administration: Grant Reports

This cooperation between the University of Maine and USDA-ARS was aimed at providing the infrastructure and manpower support for the propagation and advancement of tetraploid potato breeding materials for the USDFA-ARS-Beltsville Potato Breeding Program (K. Haynes, PI).

Pushing The Pace Of Tree Species Migration, Eli D. Lazarus, Brian Mcgill

Publications

Plants and animals have responded to past climate changes by migrating with habitable environments, sometimes shifting the boundaries of their geographic ranges by tens of kilometers per year or more. Species migrating in response to present climate conditions, however, must contend with landscapes fragmented by anthropogenic disturbance. We consider this problem in the context of wind-dispersed tree species. Mechanisms of long-distance seed dispersal make these species capable of rapid migration rates. Models of species-front migration suggest that even tree species with the capacity for long-distance dispersal will be unable to keep pace with future spatial changes in temperature gradients, exclusive …

Factors Responsible For Differences In Yield Among Lowbush Blueberry Clones, Francis A. Drummond

University of Maine Office of Research Administration: Grant Reports

Identify factors that explain differences in yield among lowbush blueberry clones. Compare high yielding clones to low yielding clones for several factors. Factors include average genetic similarity with neighbors and effects of relationship of parents in controlled crosses on fruit set, synchrony of flowering time with neighbors, freezing tolerance of closed flower buds and open flowers, floral morphological and physiological differences (nectar amounts) that might be more attractive to bees, signs of disease, etc.

Studies will focus on comparing high yielding clones to low yielding clones for several factors. Because V. angustifolium is predominantly outcrossing and self-fertility is poor due …

Potato Breeding And Variety Development For Improved Quality And Pest Resistance In The Eastern United States, Gregory Porter, Andrei Alyokhin, David Lambert, Donald Halseth, G. Yencho, John Jemison, Joshua Freeman, Keith Perry, L. Brian Perkins, Lincoln Zotarelli, Mark Clough, Mary Camire, Matthew Kleinhenz, Nicholas Dufault, Richard Veilleux, Walter De Jong, Xinshun Qu

University of Maine Office of Research Administration: Grant Reports

The eastern U.S. potato industry needs new potato varieties to overcome pest problems while reducing agricultural chemical use and to enhance marketing opportunities. This project will conduct potato breeding, germplasm enhancement, and selection studies to improve potato productivity and quality for important eastern U.S. markets. Novel and highly improved potato germplasm and varieties will be developed to reduce the impact of economically important potato pests, such as golden nematode, late blight, pink rot, and scab.

In an effort to develop suitable culture techniques for macroalgae in the Northeast, this guide reviews the current knowledge of Sargassum biology and reports on culture techniques learned during a research exchange between the United States (NOAA Sea Grant) and South Korea (National Fisheries Research and Development Institute).

Culture Of Sea Cucumbers In Korea: A Guide To Korean Methods And The Local Sea Cucumber In The Northeast U.S., Michael Pietrak, Jang K. Kim, Sarah Redmond, Young-Dae Kim, Charlie Yarish, Ian Bricknell

Maine Sea Grant Publications

In an effort to develop suitable culture techniques for sea cucumber (Cucumaria frondosa) in the Northeast, this guide reviews the current knowledge of C. frondosa biology and reports on techniques for the hatchery culture of the Japanese sea cucumber Apostichopus japonicus learned during a research exchange between the United States (NOAA Sea Grant) and South Korea (National Fisheries Research and Development Institute). The final portion of the guide discusses the potential adoption of the culture techniques for A. japonicus for use with C. frondosa.
