Best Management Practices: Sambucus Canadensis Propagation Techniques, Hannah Berendzen Jan 2025

Best Management Practices: Sambucus Canadensis Propagation Techniques, Hannah Berendzen

Graduate Theses/Dissertations

American elderberry (Sambucus nigra ssp. canadensis) is a fruit-bearing shrub native to North America, traditionally utilized for medicinal and culinary purposes. In recent years, its popularity has surged due to emerging research supporting its immune-boosting properties. Despite its growing demand, standardized best management practices for elderberry cultivation, particularly propagation techniques, remain lacking. This study aims to clarify propagation recommendations by examining the influence cutting size and stem diameter on rooting success. A field study was conducted from February to May 2024, in which one-node and two-node dormant hardwood elderberry cuttings of varying stem diameters were planted in small …


Identification Of Qtls For Berry Acids And Sugar In A Vitis Aestivalis-Derived 'Norton'-Based Population, Karlene Louise Negus Aug 2021

Identification Of Qtls For Berry Acids And Sugar In A Vitis Aestivalis-Derived 'Norton'-Based Population, Karlene Louise Negus

Graduate Theses/Dissertations

Acidity and sugar content are among the grape berry quality traits that influence wine quality. Despite advantageous environmental tolerances of Vitis aestivalis-derived ‘Norton’, its acid and sugar concentrations often deviate from expectations set for V. vinifera. Identification of the genetic determinants of malic acid, tartaric acid, pH, and total soluble solids (TSS) can assist in the improvement of new hybrid cultivars. For this purpose, a ‘Norton’ and V. vinifera ‘Cabernet Sauvignon’ hybrid mapping population containing 223 individuals was used to construct a linkage map containing 384 simple sequence repeat (SSR) and 2084 genotyping-by-sequencing (GBS)-derived single nucleotide polymorphism (SNP) …


Investigating Dicamba Tolerance In Grapevine Cultivars Through Drift Simulation Assays, Bryce David Bentley Dec 2019

Investigating Dicamba Tolerance In Grapevine Cultivars Through Drift Simulation Assays, Bryce David Bentley

Graduate Theses/Dissertations

Dicamba is a synthetic auxin herbicide which acts systematically and selectively controls broadleaf plants and has become increasingly popular in the past several years for weed control in commercial agriculture following widespread adoption of dicamba-resistant, transgenic soybean and cotton. Dicamba may be better acknowledged by growers of specialty crops, like grapes, for its capacity to drift miles away from the site of application and deposit on fields, remaining potent enough to cause crop damage and yield loss to vulnerable plants. Grapes are among the most susceptible agronomic crops to dicamba drift, showing visible injury at rates less than 1% of …
