Biochar Influences Phytochemical Concentrations of Viola cornuta Flowers

Edible flowers are a rich source of phytochemicals with potential health benefits. Yet, changes in production practices can influence the phytochemical composition edible flowers. Practices such as addition biochar have been used to affect growing media properties well conserve peat resources. However, there is little known about how affects To determine if Viola cornuta, four cultivars were subjected different rates biochar, and without fertilizer. At rate 10% fertilizer application, flower polyphenol flavonoid concentrations decreased by 10–20% two cultivars. at 25% varied widely. When was added, no effects seen. Phytochemical characterization unfertilized plants further revealed that while increased reduced certain antioxidant compounds, these compounds when added. Overall, fertilization counteract some negative on cultivars, resulting higher nutritional quality an increase bioactive produced, providing ability replace moss biochar.
