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 …

Iron Coated Sand: A Sustainable Substrate Amendment For Nutrient Management And Growth Of Floriculture Crops, Savannah Mead

Graduate Theses, Dissertations, and Problem Reports (ETD)

Acid mine drainage and phosphorus pollution are two of the most pervasive forms of water contamination in Appalachia and globally. The horticultural industry is a contributor to nutrient pollution via leaching from greenhouses, necessitating the adoption of more sustainable practices for container production in controlled environments. In this thesis, an acid mine drainage-based iron-coated sand product was assessed on its effectiveness for phosphate adsorption when used as a sustainable substrate amendment for soilless container production of flowering ornamentals. The first study centered around the amount of iron-coated sand to use for production of petunias, pansies, and chrysanthemums. Iron-coated sand at …

The Effects Of Potassium Fertilization Regime On High Tunnel Tomato Production, Sapana Pandey

Theses and Dissertations--Plant and Soil Sciences

A two-year field experiment (2022-2023) was conducted at the University of Kentucky Horticulture Research Farm in Lexington, KY to study the effects of potassium (K2O) fertilization rates on tomato yield and ripening disorders in determinate and indeterminate varieties (‘BHN-589’ and ‘Big Beef’, respectively). In the first year, K2O rates representing the soil test result-based commercial recommendation (0 lbs/acre) and sequentially greater rates (150, 300, and 450 lbs K2O/acre) were applied. In the second year, K2O rates were increased based on lack of fruit quality response and were 0, 300, 600, and 900 lbs K2O/acre. Leaf tissue nutrients, tomato yield, and …

Farmers need accurate estimates of winter cover crop biomass to make informed decisions on termination timing or to estimate potential release of nitrogen from cover crop residues to subsequent cash crops. Utilizing data from an extensive experiment across 11 states from 2016 to 2020, this study explores the most reliable predictors for determining cereal rye cover crop biomass at the time of termination. Our findings demonstrate a strong relationship between early-season and late-season cover crop biomass. Employing a random forest model, we predicted late-season cereal rye biomass with a margin of error of approximately 1,000 kg ha⁻¹ based on …

Artificial Intelligence And Image-Based Phenotyping For Monitoring Morpho-Physiological Dynamics In Grapevines, Prakriti Sharma

Electronic Theses and Dissertations

Plant phenotypic features are essential for determining the structure, composition, and function of plants. These traits are controlled by both environmental variables and genetic makeup. Conventional manual methods of phenotyping, although time-consuming and not very accurate, have laid the foundation for more modern approaches such as high throughput phenotyping (HTP). HTP utilizes imaging, sensor networks, robotics, and data analytics to automate the process of collecting and analyzing data. This study utilizes hyperspectral and digital imaging techniques to quantify physiological, biochemical, and morphological characteristics in grapevines. Hyperspectral imaging was leveraged to collect spectral data for evaluating physiological factors, whereas digital imaging …

Integrating Early Season Clover Cover Crops As A Living Mulch In Broccoli And Transitional Organic Winter Squash Production In Eastern South Dakota, Alexis Rose Barnes
