However, bioactive and nutritional qualities, especially human health protective phenolic antioxidants and associated non-communicable chronic disease (NCD) relevant health benefits of berries vary widely among accessions/cultivars and due to different production practices (organic vs conventional). Therefore, the aim of this thesis was to screen and select high phenolic and high antioxidant serviceberry and blackberry accessions/cultivars and to investigate the effect of different weed management and fertilization (organic vs. conventional) practices on phenolic bioactive linked antioxidant and anti-diabetic properties of blackberry using in vitro assay models. Overall, high phenolic-bioactive linked antioxidant and anti-hyperglycemic properties were observed in both serviceberry and blackberry accessions/cultivars and further for blackberry it was significantly higher under organic weed management and fertilization practices.NDSU policy 190.6.2https://www.ndsu.edu/fileadmin/policy/190.pdfHyperglycemia -- Prevention.Hypertension -- Prevention.Antioxidants.Phenols.Blackberries -- Organic farming.Amelanchier. -- Organic farming.Plant bioactive compounds.Thesis0000-0002-3483-3057
