Extending The Fruiting Season With Container Grown Primocane-Fruiting Blackberries Grown In A High-Tunnel, Edwin James Tucker Iii Jan 2026

Extending The Fruiting Season With Container Grown Primocane-Fruiting Blackberries Grown In A High-Tunnel, Edwin James Tucker Iii

Graduate Theses/Dissertations

Blackberry production has become an important part of many small fruit orchard operations because they’re easy to grow, produce a large crop, and sell well at market. The current blackberry season in Missouri extends from mid-June to mid-August, depending on the cultivar chosen. This fruiting season is common for floricane-fruiting blackberry cultivars (cultivars that fruit on one-year old canes). Primocane-fruiting blackberry, or blackberries that fruit on current season growth, have the potential to further extend the harvest season of blackberry into September and October especially if grown in a high-tunnel. This study had two objectives. The first objective was to …

Modeling The Impact Of Climate Change On Plant Hardiness Zones Across The Contiguous United States Using Empirical Bayesian Kriging Regression Prediction, Daniel Donkor Jan 2025

Modeling The Impact Of Climate Change On Plant Hardiness Zones Across The Contiguous United States Using Empirical Bayesian Kriging Regression Prediction, Daniel Donkor

Graduate Theses/Dissertations

Mapping plant hardiness zones is crucial to understanding and predicting the spatial distribution of plants in response to climatic conditions. The United States Department of Agriculture (USDA) developed the plant hardiness zones based on the average of annual extreme minimum temperatures using the Parameter elevation Regression on Independent Slope Model (PRISM). While the USDA’s 2012 and 2023 Plant Hardiness Zone maps remain standard references, they offer limited geostatistical transparency that causes more complications in replicating. This study applies Empirical Bayesian Kriging Regression Prediction (EBKRP) method to generate Plant Hardiness Zone maps, analyze spatial and temporal shifts in the plant hardiness …

Cold Hardiness In Vitis Interspecific Hybrid 'Chambourcin'-Based Population, Tabinda Shahid Jan 2024

Cold Hardiness In Vitis Interspecific Hybrid 'Chambourcin'-Based Population, Tabinda Shahid

Graduate Theses/Dissertations

The susceptibility of grapevines to low-temperature injury presents a significant challenge, particularly in the United States. Traditional European grape cultivar, Vitis vinifera ‘Cabernet sauvignon’, faces bud damage at temperatures below freezing. On the other hand, Vitis interspecific hybrid ‘Chambourcin’, exhibits greater tolerance to sub-zero temperatures. The objective of this research was to conduct Differential Thermal Analysis (DTA) on 273 F1 hybrid genotypes generated from a cross of ‘Chambourcin’ × ‘Cabernet Sauvignon’ to quantify bud cold hardiness by identifying the freezing exothermic reactions. Low temperature exotherm (LTE) profiles, over two dormant seasons (December to February 2022-2024), revealed 15 interspecific hybrid …

Effects Of Lemongrass Essential Oil On Galleria Mellonella Hemocytes, Kyndra Chastain Jan 2022

Effects Of Lemongrass Essential Oil On Galleria Mellonella Hemocytes, Kyndra Chastain

Graduate Theses/Dissertations

In modern agriculture, the use of pesticides is unavoidable. However, improper use has resulted in pest resistance and negative impacts on the environment and human health. Changes are needed in the agricultural industry to account for the damage already caused. Researchers have turned to essential oils as key ingredients for potential biopesticides, with some mixtures already on the market. Most studies involving essential oils and a pest’s response concentrate on mortality or interruptions in development during and between life stages. My study, however, focused on immune responses; specifically, lemongrass essential oil’s impact on Galleria mellonella. Such responses include a …

Garlic Curing: Post-Harvest Nutrient Remobilization From Leaves To Cloves, Mary L. Books Jan 2022

Garlic Curing: Post-Harvest Nutrient Remobilization From Leaves To Cloves, Mary L. Books

Graduate Theses/Dissertations

Garlic (Allium sativum L.) is grown on small and large scales worldwide. After harvesting, garlic undergoes a drying process for long-term preservation, called curing. Some producers cure with leaves intact, while others will remove and discard the leaves, curing only the bulbs. Due to the ability of plants to remobilize nutrients from leaves to underground storage organs, such as bulbs, the curing method of garlic may affect clove nutrient content. This study explores nutrient remobilization responses in garlic when cured with leaves intact compared to leaves separated from bulbs. Four cultivars of garlic, German White, Chesnok Red, Romanian Red, and …

Marker-Assisted Selection To Determine The Introgression Of Rpv-3 Mediated Downy Mildew Resistance In 'Chambourcin' X 'Caberenet Sauvignon' Grapevine Population, Kavya Sri Tummala Aug 2021

Marker-Assisted Selection To Determine The Introgression Of Rpv-3 Mediated Downy Mildew Resistance In 'Chambourcin' X 'Caberenet Sauvignon' Grapevine Population, Kavya Sri Tummala

Graduate Theses/Dissertations

Downy mildew caused by the fungus, Plasmopara viticola in the grapes is one of the major diseases affecting crop yield throughout the world. Breeding grapes via conventional methods for the downy mildew resistance will take approximately 25-30 years to fully evaluate and release new cultivars. Because of the long breeding cycle in woody plant species like grape, developing DNA markers linked to genes or quantitative trait loci (QTLs) for horticultural traits can greatly accelerate the breeding process and allow a much more accurate selection of progeny. This study aims to determine the presence of resistance in the 267 F1 genotypes …
