Assessing Freezing Effect On Kiwifruit Cultivars And Mapping Suitable Areas For Growing The Crop In Eastern Texas, Lais De Oliveira Machado
Assessing Freezing Effect On Kiwifruit Cultivars And Mapping Suitable Areas For Growing The Crop In Eastern Texas, Lais De Oliveira Machado
Electronic Theses and Dissertations
Kiwifruit is a perennial vine originating from China where it has been grown for centuries. In the United States, green kiwifruit (Actinidia deliciosa) is primarily produced commercially in California. They are fuzzy, green fleshed and well known in the marketplace. Kiwifruit plants require low to moderate soil pH, adequate winter chilling and adequate precipitation to guarantee plant development and good fructification. Actinidia chinesis or golden kiwifruit are smooth skinned, feature golden flesh and are a more recent introduction into the global market. Kiwifruit crops have attributes that favor production in east Texas, including low pest problems, current long …
Functional Diversity In Blueberries And Their Responses To Extreme Drought, Pratima Pahadi
Functional Diversity In Blueberries And Their Responses To Extreme Drought, Pratima Pahadi
Electronic Theses and Dissertations
Climate change is expected to lead to novel climate conditions with an increase in frequency and severity of drought across many places around the globe including the north-eastern (NE) United States. Therefore, experimental studies that test the impacts of changing environmental conditions over long time scales or experimental studies that mimic these conditions are crucial to understand the potential impact on crops in this region. Wild lowbush blueberries and highbush blueberries are two important crops in NE USA. In this study, the leaf functional, structural, nutrient traits across genotypes of wild blueberries (Vaccinium angustifolium and V. myrtilloides) at …
The Role Of Red Raspberry (Rubus Idaeus) On Inflammation, Lipid Metabolism, And Endothelial Dysfunction As Related To The Metabolic Syndrome, Natalie Vandenakker
The Role Of Red Raspberry (Rubus Idaeus) On Inflammation, Lipid Metabolism, And Endothelial Dysfunction As Related To The Metabolic Syndrome, Natalie Vandenakker
Electronic Theses and Dissertations
Metabolic syndrome (MetS) is major public health concern. Diet can play a major role in the prevention and/or progression of the MetS. At 8 weeks of age, male obese Zucker rat (OZR) and their lean littermates (LZR) were placed on a control or an 8% w/w whole red raspberry (WRR)-enriched diet for 8 weeks. Circulating levels of inflammatory cytokines and their gene expression in the liver and adipose tissue were evaluated. Several lipid markers were measured in the plasma, liver and adipose tissue. The expression of eight genes related to lipid metabolism were evaluated, both in liver and adipose tissue. …
Landscape Pattern And Wild Bee Communities In Maine, Brianne Du Clos
Landscape Pattern And Wild Bee Communities In Maine, Brianne Du Clos
Electronic Theses and Dissertations
Commercial production of lowbush blueberry (Vaccinium angustifolium Aiton) in Maine relies primarily on managed honeybee hives; however, naturally occurring wild bees are more efficient pollinators of the crop. Wild bees have short foraging distances and must nest near crop fields to provide pollination services. After crop bloom, the surrounding landscape must provide sufficient forage to maintain wild bee populations for the remainder of the growing season. Lowbush blueberries in Maine are produced in a mixed-use landscape with two distinct landscape contexts. Here, we document bee communities and habitat resources (nesting and floral) in power line rights-of-way and eight land …
The Enhancement Of Wild Bees (Hymenoptera: Apoidea) For Pollination Security, Eric M. Venturini
The Enhancement Of Wild Bees (Hymenoptera: Apoidea) For Pollination Security, Eric M. Venturini
Electronic Theses and Dissertations
The acreage of pollinator-dependent crops continues to expand across the globe. Simultaneously, honey bee hives – an annually rented commodity that growers rely on – are more expensive every year and in some cases, scarce. In response, pollinator-dependent growers seek alternative pollinators. One approach is installing bee pasture on farms, a strategy that enables systems-based farmers to become in-situ farm-scale habitat managers. This thesis first presents a review of the literature on bee pasture plantings and provides a brief overview of some methods for assessing their impacts on the pollinator community. There are three major gaps in current bee pasture …
Application Of Spatial Modeling Tools To Predict Native Bee Abundance In Maine's Lowbush Blueberries, Shannon J. Chapin
Application Of Spatial Modeling Tools To Predict Native Bee Abundance In Maine's Lowbush Blueberries, Shannon J. Chapin
Electronic Theses and Dissertations
Non-native honeybees historically have been used to pollinate many crops throughout the United States, however, recent population declines have revealed the need for a more sustainable pollination plan. Native bees are a natural resource that can play an important role in pollination. I used spatial modeling tools to evaluate relationships between landscape factors and native bee abundance, with a focus on the wild native bees that pollinate Maine’s lowbush blueberries. I applied the InVEST Crop Pollination ecosystem spatial modeling tool, which predicts pollinator abundance based on available floral resources and nesting habitat, to the Downeast Maine region. The InVEST model …
A Characterization Of Maine Blueberry Growers In 2010, Anya Rose
A Characterization Of Maine Blueberry Growers In 2010, Anya Rose
Electronic Theses and Dissertations
A survey was sent to 343 lowbush blueberry growers in Maine with a response rate of 29%. Growers were asked questions about their management practices, pesticide use, priorities, decision-making influences, and beliefs about pesticide safety. Respondents categorized themselves into one of four categories: Integrated Pest Management (IPM), Conventional, Organic, and No-Spray. Analyses were conducted to examine factors that were linked to these four categories. A major goal of this study was to determine differences and similarities between growers of different management styles, and to define each category by the practices and beliefs of its members. Toxicity ratings were also calculated …
Reestablishing The Juneberry On The Fort Berthold Indian Reservation: Cultural, Horticultural, And Educational Connections, Kerry E. Hartman
Reestablishing The Juneberry On The Fort Berthold Indian Reservation: Cultural, Horticultural, And Educational Connections, Kerry E. Hartman
Electronic Theses and Dissertations
Tribal people of the Northern Great Plains have utilized plants for centuries. Amelanchier anifolia (Juneberries/Serviceberries) historically played an important part in the diet and culture of the Mandan, Hidatsa, and Arikara (MHA) Tribal Nations. Research conducted as part of this study into historical and contemporary uses of the Juneberry by MHA Tribal Members indicated extensive historical use and a high interest in Juneberry reestablishment for cultural, nutritional, and economic reasons. Previous research on Juneberries has investigated factors including state of dormancy, propagation method, transplant type, and mulch type. Another purpose of this study was to elucidate the impact of presence …
Dynamics Of Bee And Wasp Populations In Maine Lowbush Blueberry (Vaccinium Angustifolium), Joseph E. Karem
Dynamics Of Bee And Wasp Populations In Maine Lowbush Blueberry (Vaccinium Angustifolium), Joseph E. Karem
Electronic Theses and Dissertations
Conservation of natural enemies can be an effective form of pest management. If beneficial Hymenoptera, native to the area, can be protected and encouraged to multiply, the benefits of natural insect pest control might be realized. Hymenoptera as "natural enemies" as well as "pollinators" have been studied intensively in many agroecosystems worldwide. However, lowbush blueberry is not an ecosystem where ecology of Hymenoptera has been well studied. This thesis discusses two studies conducted in lowbush blueberry fields in Washington County, Maine in 1997 and 1998. In the first study, I investigated "towers" as a method for deploying insect traps along …
